* throws(
* () => {
* throw err;
* },
* {
* // The `name` and `message` properties are strings and using regular
* // expressions on those will match against the string. If they fail, an
* // error is thrown.

* // The `reg` property contains a regular expression and only if the

* throws(
* () => {
* const otherErr = new Error('Not found');
* // Copy all enumerable properties from `err` to `otherErr`.
* for (const [key, value] of Object.entries(err)) {

* }
* throw otherErr;
* },
* // The error's `message` and `name` properties will also be checked when using

*
* ```js
* import assert from 'assert/strict';
*
* assert.throws(
* () => {
* throw new Error('Wrong value');
* },
* Error
* );
* ```
*
* Validate error message using [`RegExp`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions):
*
* Using a regular expression runs `.toString` on the error object, and will
* therefore also include the error name.
*
* ```js
* import assert from 'assert/strict';
*
* assert.throws(
* () => {
* throw new Error('Wrong value');
* },
* /^Error: Wrong value$/
* );
* ```
*
* Custom error validation:
*
* The function must return `true` to indicate all internal validations passed.
* It will otherwise fail with an `AssertionError`.
*
* ```js
* import assert from 'assert/strict';
*
* assert.throws(
* () => {
* throw new Error('Wrong value');
* },
* (err) => {
* assert(err instanceof Error);
* assert(/value/.test(err));
* // Avoid returning anything from validation functions besides `true`.
* // Otherwise, it's not clear what part of the validation failed. Instead,
* // throw an error about the specific validation that failed (as done in this
* // example) and add as much helpful debugging information to that error as
* // possible.
* return true;
* },
* 'unexpected error'
* );
* ```
*
* `error` cannot be a string. If a string is provided as the second
* argument, then `error` is assumed to be omitted and the string will be used for`message` instead. This can lead to easy-to-miss mistakes. Using the same
* message as the thrown error message is going to result in an`ERR_AMBIGUOUS_ARGUMENT` error. Please read the example below carefully if using
* a string as the second argument gets considered:
*
* ```js
* import assert from 'assert/strict';
*
* function throwingFirst() {
* throw new Error('First');
* }
*
* function throwingSecond() {
* throw new Error('Second');
* }
*
* function notThrowing() {}
*
* // The second argument is a string and the input function threw an Error.
* // The first case will not throw as it does not match for the error message
* // thrown by the input function!
* assert.throws(throwingFirst, 'Second');
* // In the next example the message has no benefit over the message from the
* // error and since it is not clear if the user intended to actually match
* // against the error message, Node.js throws an `ERR_AMBIGUOUS_ARGUMENT` error.
* assert.throws(throwingSecond, 'Second');
* // TypeError [ERR_AMBIGUOUS_ARGUMENT]
*
* // The string is only used (as message) in case the function does not throw:
* assert.throws(notThrowing, 'Second');
* // AssertionError [ERR_ASSERTION]: Missing expected exception: Second
*
* // If it was intended to match for the error message do this instead:
* // It does not throw because the error messages match.
* assert.throws(throwingSecond, /Second$/);
*
* // If the error message does not match, an AssertionError is thrown.
* assert.throws(throwingFirst, /Second$/);
* // AssertionError [ERR_ASSERTION]
* ```
*
* Due to the confusing error-prone notation, avoid a string as the second
* argument.

* While you can create your own implementation on top of the `async_hooks` module,`AsyncLocalStorage` should be preferred as it is a performant and memory safe
* implementation that involves significant optimizations that are non-obvious to
* implement.
*
* The following example uses `AsyncLocalStorage` to build a simple logger
* that assigns IDs to incoming HTTP requests and includes them in messages
* logged within each request.
*
* ```js
* import http from 'http';
* import { AsyncLocalStorage } from 'async_hooks';
*
* const asyncLocalStorage = new AsyncLocalStorage();
*
* function logWithId(msg) {
* const id = asyncLocalStorage.getStore();
* console.log(`${id !== undefined ? id : '-'}:`, msg);
* }
*
* let idSeq = 0;
* http.createServer((req, res) => {
* asyncLocalStorage.run(idSeq++, () => {
* logWithId('start');
* // Imagine any chain of async operations here
* setImmediate(() => {
* logWithId('finish');
* res.end();
* });
* });
* }).listen(8080);
*
* http.get('http://localhost:8080');
* http.get('http://localhost:8080');
* // Prints:
* // 0: start
* // 1: start
* // 0: finish
* // 1: finish
* ```
*
* Each instance of `AsyncLocalStorage` maintains an independent storage context.
* Multiple instances can safely exist simultaneously without risk of interfering
* with each other data.

* Causes `.exitedAfterDisconnect` to be set.
*
* After a server is closed, it will no longer accept new connections,

/**
* The `node:console` module provides a simple debugging console that is similar to
* the JavaScript console mechanism provided by web browsers.
*
* The module exports two specific components:
*
* * A `Console` class with methods such as `console.log()`, `console.error()`, and `console.warn()` that can be used to write to any Node.js stream.
* * A global `console` instance configured to write to [`process.stdout`](https://nodejs.org/docs/latest-v16.x/api/process.html#processstdout) and
* [`process.stderr`](https://nodejs.org/docs/latest-v16.x/api/process.html#processstderr). The global `console` can be used without importing the `node:console` module.
*
* _**Warning**_: The global console object's methods are neither consistently
* synchronous like the browser APIs they resemble, nor are they consistently
* asynchronous like all other Node.js streams. See the [`note on process I/O`](https://nodejs.org/docs/latest-v16.x/api/process.html#a-note-on-process-io) for
* more information.
*
* Example using the global `console`:
*
* ```js
* console.log('hello world');
* // Prints: hello world, to stdout
* console.log('hello %s', 'world');
* // Prints: hello world, to stdout
* console.error(new Error('Whoops, something bad happened'));
* // Prints error message and stack trace to stderr:
* // Error: Whoops, something bad happened
* // at [eval]:5:15
* // at Script.runInThisContext (node:vm:132:18)
* // at Object.runInThisContext (node:vm:309:38)
* // at node:internal/process/execution:77:19
* // at [eval]-wrapper:6:22
* // at evalScript (node:internal/process/execution:76:60)
* // at node:internal/main/eval_string:23:3
*
* const name = 'Will Robinson';
* console.warn(`Danger ${name}! Danger!`);
* // Prints: Danger Will Robinson! Danger!, to stderr
* ```
*
* Example using the `Console` class:
*
* ```js
* const out = getStreamSomehow();
* const err = getStreamSomehow();
* const myConsole = new console.Console(out, err);
*
* myConsole.log('hello world');
* // Prints: hello world, to out
* myConsole.log('hello %s', 'world');
* // Prints: hello world, to out
* myConsole.error(new Error('Whoops, something bad happened'));
* // Prints: [Error: Whoops, something bad happened], to err
*
* const name = 'Will Robinson';
* myConsole.warn(`Danger ${name}! Danger!`);

*
* The `msg` argument contains the message to be sent.
* Depending on its type, different behavior can apply. If `msg` is a `Buffer`,
* any `TypedArray` or a `DataView`,
* the `offset` and `length` specify the offset within the `Buffer` where the
* message begins and the number of bytes in the message, respectively.
* If `msg` is a `String`, then it is automatically converted to a `Buffer`with `'utf8'` encoding. With messages that
* contain multi-byte characters, `offset` and `length` will be calculated with
* respect to `byte length` and not the character position.
* If `msg` is an array, `offset` and `length` must not be specified.
*
* The `address` argument is a string. If the value of `address` is a host name,
* DNS will be used to resolve the address of the host. If `address` is not
* provided or otherwise falsy, `'127.0.0.1'` (for `udp4` sockets) or `'::1'` (for `udp6` sockets) will be used by default.
*
* If the socket has not been previously bound with a call to `bind`, the socket
* is assigned a random port number and is bound to the "all interfaces" address
* (`'0.0.0.0'` for `udp4` sockets, `'::0'` for `udp6` sockets.)
*
* An optional `callback` function may be specified to as a way of reporting
* DNS errors or for determining when it is safe to reuse the `buf` object.
* DNS lookups delay the time to send for at least one tick of the
* Node.js event loop.
*
* The only way to know for sure that the datagram has been sent is by using a`callback`. If an error occurs and a `callback` is given, the error will be
* passed as the first argument to the `callback`. If a `callback` is not given,
* the error is emitted as an `'error'` event on the `socket` object.
*
* Offset and length are optional but both _must_ be set if either are used.
* They are supported only when the first argument is a `Buffer`, a `TypedArray`,
* or a `DataView`.
*
* This method throws `ERR_SOCKET_BAD_PORT` if called on an unbound socket.
*
* Example of sending a UDP packet to a port on `localhost`;
*
* ```js
* import dgram from 'dgram';
* import { Buffer } from 'buffer';
*
* const message = Buffer.from('Some bytes');
* const client = dgram.createSocket('udp4');
* client.send(message, 41234, 'localhost', (err) => {
* client.close();
* });
* ```
*
* Example of sending a UDP packet composed of multiple buffers to a port on`127.0.0.1`;
*
* ```js
* import dgram from 'dgram';
* import { Buffer } from 'buffer';
*
* const buf1 = Buffer.from('Some ');
* const buf2 = Buffer.from('bytes');
* const client = dgram.createSocket('udp4');

* Sending multiple buffers might be faster or slower depending on the

* Example of sending a UDP packet using a socket connected to a port on`localhost`:
*
* ```js
* import dgram from 'dgram';
* import { Buffer } from 'buffer';
*
* const message = Buffer.from('Some bytes');
* const client = dgram.createSocket('udp4');
* client.connect(41234, 'localhost', (err) => {
* client.send(message, (err) => {
* client.close();
* });
* });
* ```
* @since v0.1.99
* @param msg Message to be sent.
* @param offset Offset in the buffer where the message starts.
* @param length Number of bytes in the message.
* @param port Destination port.
* @param address Destination host name or IP address.
* @param callback Called when the message has been sent.

/**
* Much of the Node.js core API is built around an idiomatic asynchronous
* event-driven architecture in which certain kinds of objects (called "emitters")
* emit named events that cause `Function` objects ("listeners") to be called.
*
* For instance: a `net.Server` object emits an event each time a peer
* connects to it; a `fs.ReadStream` emits an event when the file is opened;
* a `stream` emits an event whenever data is available to be read.
*
* All objects that emit events are instances of the `EventEmitter` class. These
* objects expose an `eventEmitter.on()` function that allows one or more
* functions to be attached to named events emitted by the object. Typically,
* event names are camel-cased strings but any valid JavaScript property key
* can be used.
*
* When the `EventEmitter` object emits an event, all of the functions attached
* to that specific event are called _synchronously_. Any values returned by the
* called listeners are _ignored_ and discarded.
*
* The following example shows a simple `EventEmitter` instance with a single
* listener. The `eventEmitter.on()` method is used to register listeners, while
* the `eventEmitter.emit()` method is used to trigger the event.
*
* ```js
* import EventEmitter from 'node:events';
*
* class MyEmitter extends EventEmitter {}
*
* const myEmitter = new MyEmitter();
* myEmitter.on('event', () => {
* console.log('an event occurred!');
* });
* myEmitter.emit('event');
* ```
* @see [source](https://github.com/nodejs/node/blob/v16.9.0/lib/events.js)

* The `Promise` will resolve with an array of all the arguments emitted to the

*
* This method is intentionally generic and works with the web platform [EventTarget](https://dom.spec.whatwg.org/#interface-eventtarget) interface, which has no special`'error'` event
* semantics and does not listen to the `'error'` event.
*
* ```js
* import { once, EventEmitter } from 'node:events';
*
* async function run() {
* const ee = new EventEmitter();
*
* process.nextTick(() => {

* try {
* await once(ee, 'myevent');
* } catch (err) {
* console.log('error happened', err);
* }
* }
*
* run();
* ```
*
* The special handling of the `'error'` event is only used when `events.once()`is used to wait for another event. If `events.once()` is used to wait for the
* '`error'` event itself, then it is treated as any other kind of event without
* special handling:
*
* ```js
* import { EventEmitter, once } from 'node:events';
*
* const ee = new EventEmitter();
*
* once(ee, 'error')
* .then(([err]) => console.log('ok', err.message))
* .catch((err) => console.log('error', err.message));
*
* ee.emit('error', new Error('boom'));
*
* // Prints: ok boom
* ```
*

*
* ```js
* import { EventEmitter, once } from 'node:events';
*
* const ee = new EventEmitter();
* const ac = new AbortController();
*
* async function foo(emitter, event, signal) {

* }
* }
* }
*
* foo(ee, 'foo', ac.signal);

*
* Once an event is emitted, all listeners attached to it at the

* const myEmitter = new MyEmitter();

* // Prints:
* // A
* // B
*
* // callbackB is now removed.

* myEmitter.emit('event');

*
* Because listeners are managed using an internal array, calling this will
* change the position indices of any listener registered _after_ the listener
* being removed. This will not impact the order in which listeners are called,
* but it means that any copies of the listener array as returned by
* the `emitter.listeners()` method will need to be recreated.
*
* When a single function has been added as a handler multiple times for a single
* event (as in the example below), `removeListener()` will remove the most

/**
* Makes a request to a secure web server.
*
* The following additional `options` from `tls.connect()` are also accepted:`ca`, `cert`, `ciphers`, `clientCertEngine`, `crl`, `dhparam`, `ecdhCurve`, `honorCipherOrder`, `key`, `passphrase`,
* `pfx`, `rejectUnauthorized`, `secureOptions`, `secureProtocol`, `servername`, `sessionIdContext`, `highWaterMark`.
*
* `options` can be an object, a string, or a `URL` object. If `options` is a
* string, it is automatically parsed with `new URL()`. If it is a `URL` object, it will be automatically converted to an ordinary `options` object.
*
* `https.request()` returns an instance of the `http.ClientRequest` class. The `ClientRequest` instance is a writable stream. If one needs to
* upload a file with a POST request, then write to the `ClientRequest` object.
*
* ```js
* import https from 'node:https';
*
* const options = {
* hostname: 'encrypted.google.com',
* port: 443,
* path: '/',
* method: 'GET'
* };
*
* const req = https.request(options, (res) => {
* console.log('statusCode:', res.statusCode);
* console.log('headers:', res.headers);
*
* res.on('data', (d) => {
* process.stdout.write(d);
* });
* });
*
* req.on('error', (e) => {
* console.error(e);
* });
* req.end();
* ```
*
* Example using options from `tls.connect()`:
*
* ```js
* const options = {
* hostname: 'encrypted.google.com',
* port: 443,
* path: '/',
* method: 'GET',
* key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
* cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
* };
* options.agent = new https.Agent(options);
*
* const req = https.request(options, (res) => {
* // ...
* });
* ```
*
* Alternatively, opt out of connection pooling by not using an `Agent`.
*
* ```js
* const options = {
* hostname: 'encrypted.google.com',
* port: 443,
* path: '/',
* method: 'GET',
* key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
* cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem'),
* agent: false
* };
*
* const req = https.request(options, (res) => {
* // ...
* });
* ```
*
* Example using a `URL` as `options`:
*
* ```js
* const options = new URL('https://abc:[email protected]');
*
* const req = https.request(options, (res) => {
* // ...
* });
* ```
*
* Example pinning on certificate fingerprint, or the public key (similar to`pin-sha256`):
*
* ```js
* import tls from 'node:tls';
* import https from 'node:https';
* import crypto from 'node:crypto';
*
* function sha256(s) {
* return crypto.createHash('sha256').update(s).digest('base64');
* }
* const options = {
* hostname: 'github.com',
* port: 443,
* path: '/',
* method: 'GET',
* checkServerIdentity: function(host, cert) {
* // Make sure the certificate is issued to the host we are connected to
* const err = tls.checkServerIdentity(host, cert);
* if (err) {
* return err;
* }
*
* // Pin the public key, similar to HPKP pin-sha25 pinning
* const pubkey256 = 'pL1+qb9HTMRZJmuC/bB/ZI9d302BYrrqiVuRyW+DGrU=';
* if (sha256(cert.pubkey) !== pubkey256) {
* const msg = 'Certificate verification error: ' +
* `The public key of '${cert.subject.CN}' ` +
* 'does not match our pinned fingerprint';
* return new Error(msg);
* }
*
* // Pin the exact certificate, rather than the pub key
* const cert256 = '25:FE:39:32:D9:63:8C:8A:FC:A1:9A:29:87:' +
* 'D8:3E:4C:1D:98:DB:71:E4:1A:48:03:98:EA:22:6A:BD:8B:93:16';
* if (cert.fingerprint256 !== cert256) {
* const msg = 'Certificate verification error: ' +
* `The certificate of '${cert.subject.CN}' ` +
* 'does not match our pinned fingerprint';
* return new Error(msg);
* }
*
* // This loop is informational only.
* // Print the certificate and public key fingerprints of all certs in the
* // chain. Its common to pin the public key of the issuer on the public
* // internet, while pinning the public key of the service in sensitive
* // environments.
* do {
* console.log('Subject Common Name:', cert.subject.CN);
* console.log(' Certificate SHA256 fingerprint:', cert.fingerprint256);
*
* hash = crypto.createHash('sha256');
* console.log(' Public key ping-sha256:', sha256(cert.pubkey));

* });
*
* req.on('error', (e) => {

* });
* req.end();

*
* This function is asynchronous. When the server starts listening, the `'listening'` event will be emitted. The last parameter `callback`will be added as a listener for the `'listening'`
* event.
*
* All `listen()` methods can take a `backlog` parameter to specify the maximum
* length of the queue of pending connections. The actual length will be determined

* error during the first `server.listen()` call or `server.close()` has been

*
* ```console

*
* ```js

* ```js

*
* [Punycode](https://tools.ietf.org/html/rfc3492) is a character encoding scheme defined by RFC 3492 that is
* primarily intended for use in Internationalized Domain Names. Because host
* names in URLs are limited to ASCII characters only, Domain Names that contain
* non-ASCII characters must be converted into ASCII using the Punycode scheme.
* For instance, the Japanese character that translates into the English word,`'example'` is `'例'`. The Internationalized Domain Name, `'例.com'` (equivalent
* to `'example.com'`) is represented by Punycode as the ASCII string`'xn--fsq.com'`.
*
* The `punycode` module provides a simple implementation of the Punycode standard.
*
* The `punycode` module is a third-party dependency used by Node.js and
* made available to developers as a convenience. Fixes or other modifications to
* the module must be directed to the [Punycode.js](https://github.com/bestiejs/punycode.js) project.

*
* ```js
* import readline from 'node:readline';
* const rl = readline.createInterface({
* input: process.stdin,

*

* break;
* }
* rl.prompt();
* }).on('close', () => {
* console.log('Have a great day!');
* process.exit(0);
* });
* ```
*
* ## Example: Read file stream line-by-Line
*
* A common use case for `readline` is to consume an input file one line at a
* time. The easiest way to do so is leveraging the `fs.ReadStream` API as
* well as a `for await...of` loop:
*
* ```js
* import fs from 'node:fs';
* import readline from 'node:readline';
*
* async function processLineByLine() {
* const fileStream = fs.createReadStream('input.txt');
*
* const rl = readline.createInterface({
* input: fileStream,
* crlfDelay: Infinity
* });
* // Note: we use the crlfDelay option to recognize all instances of CR LF

* // Each line in input.txt will be successively available here as `line`.
* console.log(`Line from file: ${line}`);
* }
* }
*
* processLineByLine();
* ```
*
* Alternatively, one could use the `'line'` event:
*
* ```js
* import fs from 'node:fs';
* import readline from 'node:readline';
*
* const rl = readline.createInterface({
* input: fs.createReadStream('sample.txt'),
* crlfDelay: Infinity
* });
*
* rl.on('line', (line) => {
* console.log(`Line from file: ${line}`);
* });
* ```
*
* Currently, `for await...of` loop can be a bit slower. If `async` / `await`flow and speed are both essential, a mixed approach can be applied:
*
* ```js
* import { once } from 'node:events';
* import { createReadStream } from 'node:fs';
* import { createInterface } from 'node:readline';
*
* (async function processLineByLine() {
* try {
* const rl = createInterface({
* input: createReadStream('big-file.txt'),
* crlfDelay: Infinity
* });
*
* rl.on('line', (line) => {
* // Process the line.
* });
*
* await once(rl, 'close');
*
* console.log('File processed.');
* } catch (err) {
* console.error(err);
* }
* })();
* ```
* @since v0.7.7
* @param callback Invoked once the operation completes.
* @return `false` if `stream` wishes for the calling code to wait for the `'drain'` event to be emitted before continuing to write additional data; otherwise `true`.

/**
* The `node:string_decoder` module provides an API for decoding `Buffer` objects
* into strings in a manner that preserves encoded multi-byte UTF-8 and UTF-16
* characters. It can be accessed using:
*
* ```js
* import { StringDecoder } from 'node:string_decoder';
* ```
*
* The following example shows the basic use of the `StringDecoder` class.
*
* ```js
* import { StringDecoder } from 'node:string_decoder';
* const decoder = new StringDecoder('utf8');
*
* const cent = Buffer.from([0xC2, 0xA2]);
* console.log(decoder.write(cent)); // Prints: ¢
*
* const euro = Buffer.from([0xE2, 0x82, 0xAC]);
* console.log(decoder.write(euro)); // Prints: €
* ```
*
* When a `Buffer` instance is written to the `StringDecoder` instance, an
* internal buffer is used to ensure that the decoded string does not contain
* any incomplete multibyte characters. These are held in the buffer until the
* next call to `stringDecoder.write()` or until `stringDecoder.end()` is called.
*
* In the following example, the three UTF-8 encoded bytes of the European Euro
* symbol (`€`) are written over three separate operations:
*
* ```js
* import { StringDecoder } from 'node:string_decoder';
* const decoder = new StringDecoder('utf8');
*
* decoder.write(Buffer.from([0xE2]));
* decoder.write(Buffer.from([0x82]));
* console.log(decoder.end(Buffer.from([0xAC]))); // Prints: €
* ```

/**
* The `trace_events` module provides a mechanism to centralize tracing information
* generated by V8, Node.js core, and userspace code.
*
* Tracing can be enabled with the `--trace-event-categories` command-line flag
* or by using the `trace_events` module. The `--trace-event-categories` flag
* accepts a list of comma-separated category names.
*
* The available categories are:
*
* * `node`: An empty placeholder.
* * `node.async_hooks`: Enables capture of detailed `async_hooks` trace data.
* The `async_hooks` events have a unique `asyncId` and a special `triggerId` `triggerAsyncId` property.
* * `node.bootstrap`: Enables capture of Node.js bootstrap milestones.
* * `node.console`: Enables capture of `console.time()` and `console.count()` output.
* * `node.dns.native`: Enables capture of trace data for DNS queries.
* * `node.environment`: Enables capture of Node.js Environment milestones.
* * `node.fs.sync`: Enables capture of trace data for file system sync methods.
* * `node.perf`: Enables capture of `Performance API` measurements.
* * `node.perf.usertiming`: Enables capture of only Performance API User Timing
* measures and marks.
* * `node.perf.timerify`: Enables capture of only Performance API timerify
* measurements.
* * `node.promises.rejections`: Enables capture of trace data tracking the number
* of unhandled Promise rejections and handled-after-rejections.
* * `node.vm.script`: Enables capture of trace data for the `vm` module's`runInNewContext()`, `runInContext()`, and `runInThisContext()` methods.
* * `v8`: The `V8` events are GC, compiling, and execution related.
*
* By default the `node`, `node.async_hooks`, and `v8` categories are enabled.
*
* ```bash
* node --trace-event-categories v8,node,node.async_hooks server.js
* ```
*
* Prior versions of Node.js required the use of the `--trace-events-enabled`flag to enable trace events. This requirement has been removed. However, the`--trace-events-enabled` flag _may_ still be
* used and will enable the`node`, `node.async_hooks`, and `v8` trace event categories by default.
*
* ```bash
* node --trace-events-enabled
*
* # is equivalent to
*
* node --trace-event-categories v8,node,node.async_hooks
* ```
*
* Alternatively, trace events may be enabled using the `trace_events` module:
*
* ```js
* import trace_events from 'node:trace_events';
* const tracing = trace_events.createTracing({ categories: ['node.perf'] });
* tracing.enable(); // Enable trace event capture for the 'node.perf' category
*
* // do work
*
* tracing.disable(); // Disable trace event capture for the 'node.perf' category
* ```

* Running Node.js with tracing enabled will produce log files that can be opened
* in the [`chrome://tracing`](https://www.chromium.org/developers/how-tos/trace-event-profiling-tool) tab of Chrome.
*
* The logging file is by default called `node_trace.${rotation}.log`, where`${rotation}` is an incrementing log-rotation id. The filepath pattern can
* be specified with `--trace-event-file-pattern` that accepts a template
* string that supports `${rotation}` and `${pid}`:
*
* ```bash
* node --trace-event-categories v8 --trace-event-file-pattern '${pid}-${rotation}.log' server.js

*
* The tracing system uses the same time source
* as the one used by `process.hrtime()`.
* However the trace-event timestamps are expressed in microseconds,
* unlike `process.hrtime()` which returns nanoseconds.

*
* ## Example: Running an HTTP server within a VM
*
* When using either `script.runInThisContext()` or {@link runInThisContext}, the code is executed within the current V8 global
* context. The code passed to this VM context will have its own isolated scope.
*
* In order to run a simple web server using the `http` module the code passed to
* the context must either call `require('http')` on its own, or have a reference
* to the `http` module passed to it. For instance:
*
* ```js
* 'use strict';
* import vm from 'node:vm';
*
* const code = `
* ((require) => {
* const http = require('node:http');

*
* console.log('Server running at http://127.0.0.1:8124/');
* })`;
*
* vm.runInThisContext(code)(require);
* ```
*
* The `require()` in the above case shares the state with the context it is
* passed from. This may introduce risks when untrusted code is executed, e.g.
* altering objects in the context in unwanted ways.
* @since v0.3.1

/**
* The `worker_threads` module enables the use of threads that execute JavaScript
* in parallel. To access it:
*
* ```js
* import worker from 'node:worker_threads';
* ```
*
* Workers (threads) are useful for performing CPU-intensive JavaScript operations.
* They do not help much with I/O-intensive work. The Node.js built-in
* asynchronous I/O operations are more efficient than Workers can be.
*
* Unlike `child_process` or `cluster`, `worker_threads` can share memory. They do
* so by transferring `ArrayBuffer` instances or sharing `SharedArrayBuffer`instances.
*
* ```js
* import {
* Worker, isMainThread, parentPort, workerData
* } from 'node:worker_threads';
* import { parse } from 'some-js-parsing-library';
*
* if (isMainThread) {
* module.exports = function parseJSAsync(script) {
* return new Promise((resolve, reject) => {
* const worker = new Worker(__filename, {
* workerData: script
* });
* worker.on('message', resolve);
* worker.on('error', reject);
* worker.on('exit', (code) => {
* if (code !== 0)
* reject(new Error(`Worker stopped with exit code ${code}`));
* });
* });
* };
* } else {
* const script = workerData;
* parentPort.postMessage(parse(script));
* }
* ```
*
* The above example spawns a Worker thread for each `parse()` call. In actual
* practice, use a pool of Workers for these kinds of tasks. Otherwise, the
* overhead of creating Workers would likely exceed their benefit.
*
* When implementing a worker pool, use the `AsyncResource` API to inform
* diagnostic tools (e.g. to provide asynchronous stack traces) about the
* correlation between tasks and their outcomes. See `"Using AsyncResource for a Worker thread pool"` in the `async_hooks` documentation for an example implementation.
*
* Worker threads inherit non-process-specific options by default. Refer to `Worker constructor options` to know how to customize worker thread options,
* specifically `argv` and `execArgv` options.

*
* `transferList` may be a list of [`ArrayBuffer`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer), `MessagePort` and `FileHandle` objects.
* After transferring, they are not usable on the sending side of the channel
* anymore (even if they are not contained in `value`). Unlike with `child processes`, transferring handles such as network sockets is currently
* not supported.
*
* If `value` contains [`SharedArrayBuffer`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer) instances, those are accessible
* from either thread. They cannot be listed in `transferList`.
*
* `value` may still contain `ArrayBuffer` instances that are not in`transferList`; in that case, the underlying memory is copied rather than moved.
*
* ```js
* import { MessageChannel } from 'node:worker_threads';
* const { port1, port2 } = new MessageChannel();
*
* port1.on('message', (message) => console.log(message));
*
* const uint8Array = new Uint8Array([ 1, 2, 3, 4 ]);
* // This posts a copy of `uint8Array`:
* port2.postMessage(uint8Array);
* // This does not copy data, but renders `uint8Array` unusable:
* port2.postMessage(uint8Array, [ uint8Array.buffer ]);
*
* // The memory for the `sharedUint8Array` is accessible from both the
* // original and the copy received by `.on('message')`:
* const sharedUint8Array = new Uint8Array(new SharedArrayBuffer(4));
* port2.postMessage(sharedUint8Array);
*
* // This transfers a freshly created message port to the receiver.
* // This can be used, for example, to create communication channels between
* // multiple `Worker` threads that are children of the same parent thread.
* const otherChannel = new MessageChannel();
* port2.postMessage({ port: otherChannel.port1 }, [ otherChannel.port1 ]);

* when the `Worker` is created. While the `MessagePort` object on the parent side
* is not directly exposed, its functionalities are exposed through `worker.postMessage()` and the `worker.on('message')` event
* on the `Worker` object for the parent thread.
*
* To create custom messaging channels (which is encouraged over using the default
* global channel because it facilitates separation of concerns), users can create
* a `MessageChannel` object on either thread and pass one of the`MessagePort`s on that `MessageChannel` to the other thread through a

/**
* The `zlib` module provides compression functionality implemented using Gzip,
* Deflate/Inflate, and Brotli.
*
* To access it:
*
* ```js
* import zlib from 'node:zlib';
* ```
*
* Compression and decompression are built around the Node.js `Streams API`.
*
* Compressing or decompressing a stream (such as a file) can be accomplished by
* piping the source stream through a `zlib` `Transform` stream into a destination
* stream:
*
* ```js
* import { createGzip } from 'node:zlib';
* import { pipeline } from 'node:stream';
* import {
* createReadStream,
* createWriteStream
* } from 'node:fs';
*
* const gzip = createGzip();
* const source = createReadStream('input.txt');
* const destination = createWriteStream('input.txt.gz');
*
* pipeline(source, gzip, destination, (err) => {
* if (err) {
* console.error('An error occurred:', err);
* process.exitCode = 1;
* }
* });
*
* // Or, Promisified
*
* import { promisify } from 'node:util';
* const pipe = promisify(pipeline);
*
* async function do_gzip(input, output) {
* const gzip = createGzip();
* const source = createReadStream(input);
* const destination = createWriteStream(output);
* await pipe(source, gzip, destination);
* }
*
* do_gzip('input.txt', 'input.txt.gz')
* .catch((err) => {
* console.error('An error occurred:', err);
* process.exitCode = 1;
* });
* ```
*
* It is also possible to compress or decompress data in a single step:
*
* ```js
* import { deflate, unzip } from 'node:zlib';
*
* const input = '.................................';
* deflate(input, (err, buffer) => {
* if (err) {
* console.error('An error occurred:', err);
* process.exitCode = 1;
* }
* console.log(buffer.toString('base64'));
* });
*
* const buffer = Buffer.from('eJzT0yMAAGTvBe8=', 'base64');
* unzip(buffer, (err, buffer) => {
* if (err) {
* console.error('An error occurred:', err);
* process.exitCode = 1;
* }
* console.log(buffer.toString());
* });
*
* // Or, Promisified
*
* import { promisify } from 'node:util';
* const do_unzip = promisify(unzip);
*
* do_unzip(buffer)
* .then((buf) => console.log(buf.toString()))
* .catch((err) => {
* console.error('An error occurred:', err);
* process.exitCode = 1;
* });
* ```

Native Abstractions for Node.js
===============================
**A header file filled with macro and utility goodness for making add-on development for Node.js easier across versions 8, 10, 12, 14, 16, 17, 18, 19, 20, 21, 22, 23, 24 and 25.**
***Current version: 2.24.0***
*(See [CHANGELOG.md](https://github.com/nodejs/nan/blob/master/CHANGELOG.md) for complete ChangeLog)*
[![NPM](https://nodei.co/npm/nan.png?downloads=true&downloadRank=true)](https://nodei.co/npm/nan/) [![NPM](https://nodei.co/npm-dl/nan.png?months=6&height=3)](https://nodei.co/npm/nan/)
[![Build status](https://ci.appveyor.com/api/projects/status/kh73pbm9dsju7fgh)](https://ci.appveyor.com/project/RodVagg/nan)
Thanks to the crazy changes in V8 (and some in Node core), keeping native addons compiling happily across versions, particularly 0.10 to 0.12 to 4.0, is a minor nightmare. The goal of this project is to store all logic necessary to develop native Node.js addons without having to inspect `NODE_MODULE_VERSION` and get yourself into a macro-tangle.
This project also contains some helper utilities that make addon development a bit more pleasant.

<a name="news"></a>
## News & Updates
<a name="usage"></a>
## Usage
Simply add **NAN** as a dependency using a package manager like npm, yarn, or bun:
``` bash
$ npm install nan
```
Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include <nan.h>` in your *.cpp* files:
``` python
"include_dirs" : [
"<!(node -e \"require('nan')\")"
]
```
This works like a `-I<path-to-NAN>` when compiling your addon.
<a name="example"></a>
## Example
Just getting started with Nan? Take a look at the **[Node Add-on Examples](https://github.com/nodejs/node-addon-examples)**.
Refer to a [quick-start **Nan** Boilerplate](https://github.com/fcanas/node-native-boilerplate) for a ready-to-go project that utilizes basic Nan functionality.
For a simpler example, see the **[async pi estimation example](https://github.com/nodejs/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does. Below are just some parts of the full example that illustrate the use of **NAN**.
Yet another example is **[nan-example-eol](https://github.com/CodeCharmLtd/nan-example-eol)**. It shows newline detection implemented as a native addon.
Also take a look at our comprehensive **[C++ test suite](https://github.com/nodejs/nan/tree/master/test/cpp)** which has a plethora of code snippets for your pasting pleasure.
<a name="api"></a>
## API
Additional to the NAN documentation below, please consult:
* [The V8 Getting Started * Guide](https://v8.dev/docs/embed)
* [V8 API Documentation](https://v8docs.nodesource.com/)
* [Node Add-on Documentation](https://nodejs.org/api/addons.html)
<!-- START API -->
### JavaScript-accessible methods
A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

### Scopes
A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
- <a href="doc/scopes.md#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
- <a href="doc/scopes.md#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
### Persistent references
An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://v8.dev/docs/embed#handles-and-garbage-collection).
### New
NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.

- <a href="doc/new.md#api_nan_empty_string"><b><code>Nan::EmptyString()</code></b></a>
### Converters
NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
- <a href="doc/converters.md#api_nan_to"><b><code>Nan::To()</code></b></a>
### Maybe Types
The `Nan::MaybeLocal` and `Nan::Maybe` types are monads that encapsulate `v8::Local` handles that _may be empty_.

- <a href="doc/maybe_types.md#api_nan_make_maybe"><b><code>Nan::MakeMaybe()</code></b></a>
### Script
NAN provides `v8::Script` helpers as the API has changed over the supported versions of V8.
- <a href="doc/script.md#api_nan_compile_script"><b><code>Nan::CompileScript()</code></b></a>
- <a href="doc/script.md#api_nan_run_script"><b><code>Nan::RunScript()</code></b></a>
- <a href="doc/script.md#api_nan_script_origin"><b><code>Nan::ScriptOrigin</code></b></a>
### JSON
The _JSON_ object provides the C++ versions of the methods offered by the `JSON` object in javascript. V8 exposes these methods via the `v8::JSON` object.
- <a href="doc/json.md#api_nan_json_parse"><b><code>Nan::JSON.Parse</code></b></a>
- <a href="doc/json.md#api_nan_json_stringify"><b><code>Nan::JSON.Stringify</code></b></a>
Refer to the V8 JSON object in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/da/d6f/classv8_1_1_j_s_o_n.html) for more information about these methods and their arguments.
### Errors
NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted.
Note that an Error object is simply a specialized form of `v8::Value`.
Also consult the V8 Embedders Guide section on [Exceptions](https://v8.dev/docs/embed#exceptions) for more information.

- <a href="doc/errors.md#api_nan_try_catch"><b><code>Nan::TryCatch</code></b></a>
### Buffers
NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.
- <a href="doc/buffers.md#api_nan_new_buffer"><b><code>Nan::NewBuffer()</code></b></a>
- <a href="doc/buffers.md#api_nan_copy_buffer"><b><code>Nan::CopyBuffer()</code></b></a>
- <a href="doc/buffers.md#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
### Nan::Callback
`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
- <a href="doc/callback.md#api_nan_callback"><b><code>Nan::Callback</code></b></a>
### Asynchronous work helpers
`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

- <a href="doc/asyncworker.md#api_nan_async_queue_worker"><b><code>Nan::AsyncQueueWorker</code></b></a>
### Strings & Bytes
Miscellaneous string & byte encoding and decoding functionality provided for compatibility across supported versions of V8 and Node. Implemented by NAN to ensure that all encoding types are supported, even for older versions of Node where they are missing.

- <a href="doc/object_wrappers.md#api_nan_object_wrap"><b><code>Nan::ObjectWrap</code></b></a>
### V8 internals
The hooks to access V8 internals—including GC and statistics—are different across the supported versions of V8, therefore NAN provides its own hooks that call the appropriate V8 methods.

## Known issues
### Compiling against Node.js 0.12 on OSX
With new enough compilers available on OSX, the versions of V8 headers corresponding to Node.js 0.12
do not compile anymore. The error looks something like:
```
❯ CXX(target) Release/obj.target/accessors/cpp/accessors.o
In file included from ../cpp/accessors.cpp:9:
In file included from ../../nan.h:51:
In file included from /Users/ofrobots/.node-gyp/0.12.18/include/node/node.h:61:
/Users/ofrobots/.node-gyp/0.12.18/include/node/v8.h:5800:54: error: 'CreateHandle' is a protected member of 'v8::HandleScope'
return Handle<T>(reinterpret_cast<T*>(HandleScope::CreateHandle(
~~~~~~~~~~~~~^~~~~~~~~~~~
```
This can be worked around by patching your local versions of v8.h corresponding to Node 0.12 to make
`v8::Handle` a friend of `v8::HandleScope`. Since neither Node.js not V8 support this release line anymore
this patch cannot be released by either project in an official release.
For this reason, we do not test against Node.js 0.12 on OSX in this project's CI. If you need to support
that configuration, you will need to either get an older compiler, or apply a source patch to the version
of V8 headers as a workaround.

## Governance & Contributing
NAN is governed by the [Node.js Addon API Working Group](https://github.com/nodejs/CTC/blob/master/WORKING_GROUPS.md#addon-api)
### Addon API Working Group (WG)
The NAN project is jointly governed by a Working Group which is responsible for high-level guidance of the project.
Members of the WG are also known as Collaborators, there is no distinction between the two, unlike other Node.js projects.
The WG has final authority over this project including:
* Technical direction
* Project governance and process (including this policy)
* Contribution policy
* GitHub repository hosting
* Maintaining the list of additional Collaborators
For the current list of WG members, see the project [README.md](./README.md#collaborators).
Individuals making significant and valuable contributions are made members of the WG and given commit-access to the project. These individuals are identified by the WG and their addition to the WG is discussed via GitHub and requires unanimous consensus amongst those WG members participating in the discussion with a quorum of 50% of WG members required for acceptance of the vote.
_Note:_ If you make a significant contribution and are not considered for commit-access log an issue or contact a WG member directly.
For the current list of WG members / Collaborators, see the project [README.md](./README.md#collaborators).
### Consensus Seeking Process
The WG follows a [Consensus Seeking](https://en.wikipedia.org/wiki/Consensus-seeking_decision-making) decision making model.
Modifications of the contents of the NAN repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification.
If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG. Simple majority wins.

## Asynchronous work helpers
`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

### Nan::AsyncWorker
`Nan::AsyncWorker` is an _abstract_ class that you can subclass to have much of the annoying asynchronous queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the asynchronous work is in progress.
This class internally handles the details of creating an [`AsyncResource`][AsyncResource], and running the callback in the
correct async context. To be able to identify the async resources created by this class in async-hooks, provide a
`resource_name` to the constructor. It is recommended that the module name be used as a prefix to the `resource_name` to avoid
collisions in the names. For more details see [`AsyncResource`][AsyncResource] documentation. The `resource_name` needs to stay valid for the lifetime of the worker instance.
Definition:
```c++
class AsyncWorker {
public:
explicit AsyncWorker(Callback *callback_, const char* resource_name = "nan:AsyncWorker");
virtual ~AsyncWorker();
virtual void WorkComplete();
void SaveToPersistent(const char *key, const v8::Local<v8::Value> &value);
void SaveToPersistent(const v8::Local<v8::String> &key,
const v8::Local<v8::Value> &value);
void SaveToPersistent(uint32_t index,
const v8::Local<v8::Value> &value);
v8::Local<v8::Value> GetFromPersistent(const char *key) const;
v8::Local<v8::Value> GetFromPersistent(const v8::Local<v8::String> &key) const;
v8::Local<v8::Value> GetFromPersistent(uint32_t index) const;
virtual void Execute() = 0;
uv_work_t request;
virtual void Destroy();
protected:
Persistent<v8::Object> persistentHandle;
Callback *callback;

### Nan::AsyncProgressWorkerBase &amp; Nan::AsyncProgressWorker
`Nan::AsyncProgressWorkerBase` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
Previously the definition of `Nan::AsyncProgressWorker` only allowed sending `const char` data. Now extending `Nan::AsyncProgressWorker` will yield an instance of the implicit `Nan::AsyncProgressWorkerBase` template with type `<char>` for compatibility.
`Nan::AsyncProgressWorkerBase` &amp; `Nan::AsyncProgressWorker` is intended for best-effort delivery of nonessential progress messages, e.g. a progress bar. The last event sent before the main thread is woken will be delivered.
Definition:
```c++
template<class T>
class AsyncProgressWorkerBase<T> : public AsyncWorker {
public:
explicit AsyncProgressWorkerBase(Callback *callback_, const char* resource_name = ...);
virtual ~AsyncProgressWorkerBase();
void WorkProgress();
class ExecutionProgress {
public:
void Signal() const;
void Send(const T* data, size_t count) const;
};
virtual void Execute(const ExecutionProgress& progress) = 0;
virtual void HandleProgressCallback(const T *data, size_t count) = 0;
virtual void Destroy();
};
typedef AsyncProgressWorkerBase<T> AsyncProgressWorker;
```

### Nan::AsyncProgressQueueWorker
`Nan::AsyncProgressQueueWorker` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
`Nan::AsyncProgressQueueWorker` behaves exactly the same as `Nan::AsyncProgressWorker`, except all events are queued and delivered to the main thread.
Definition:
```c++
template<class T>
class AsyncProgressQueueWorker<T> : public AsyncWorker {
public:
explicit AsyncProgressQueueWorker(Callback *callback_, const char* resource_name = "nan:AsyncProgressQueueWorker");
virtual ~AsyncProgressQueueWorker();
void WorkProgress();
class ExecutionProgress {
public:
void Send(const T* data, size_t count) const;
};
virtual void Execute(const ExecutionProgress& progress) = 0;
virtual void HandleProgressCallback(const T *data, size_t count) = 0;
virtual void Destroy();
};
```
<a name="api_nan_async_queue_worker"></a>
### Nan::AsyncQueueWorker
`Nan::AsyncQueueWorker` will run a `Nan::AsyncWorker` asynchronously via libuv. Both the `execute` and `after_work` steps are taken care of for you. Most of the logic for this is embedded in `Nan::AsyncWorker`.
Definition:
```c++
void AsyncQueueWorker(AsyncWorker *);

## Buffers
NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.
- <a href="#api_nan_new_buffer"><b><code>Nan::NewBuffer()</code></b></a>
- <a href="#api_nan_copy_buffer"><b><code>Nan::CopyBuffer()</code></b></a>
- <a href="#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
<a name="api_nan_new_buffer"></a>
### Nan::NewBuffer()
Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
You _must not_ free the memory space manually once you have created a `Buffer` in this way.
Signature:
```c++
Nan::MaybeLocal<v8::Object> Nan::NewBuffer(uint32_t size)
Nan::MaybeLocal<v8::Object> Nan::NewBuffer(char* data, uint32_t size)
Nan::MaybeLocal<v8::Object> Nan::NewBuffer(char *data,
size_t length,
Nan::FreeCallback callback,
void *hint)
```
<a name="api_nan_copy_buffer"></a>
### Nan::CopyBuffer()
Similar to [`Nan::NewBuffer()`](#api_nan_new_buffer) except that an implicit memcpy will occur within Node. Calls `node::Buffer::Copy()`.
Management of the `char*` is left to the user, you should manually free the memory space if necessary as the new `Buffer` will have its own copy.
Signature:
```c++
Nan::MaybeLocal<v8::Object> Nan::CopyBuffer(const char *data, uint32_t size)
```
<a name="api_nan_free_callback"></a>
### Nan::FreeCallback()
A free callback that can be provided to [`Nan::NewBuffer()`](#api_nan_new_buffer).
The supplied callback will be invoked when the `Buffer` undergoes garbage collection.
Signature:
```c++
typedef void (*FreeCallback)(char *data, void *hint);
```

## Nan::Callback
`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
- <a href="#api_nan_callback"><b><code>Nan::Callback</code></b></a>
<a name="api_nan_callback"></a>
### Nan::Callback
```c++
class Callback {
public:

bool operator==(const Callback &other) const;
bool operator!=(const Callback &other) const;

v8::Local<v8::Value> argv[],
AsyncResource* async_resource) const;
MaybeLocal<v8::Value> Call(int argc,
v8::Local<v8::Value> argv[],
AsyncResource* async_resource) const;
// Deprecated versions. Use the versions that accept an async_resource instead
// as they run the callback in the correct async context as specified by the
// resource. If you want to call a synchronous JS function (i.e. on a
// non-empty JS stack), you can use Nan::Call instead.
v8::Local<v8::Value> operator()(v8::Local<v8::Object> target,
int argc = 0,
v8::Local<v8::Value> argv[] = 0) const;
v8::Local<v8::Value> operator()(int argc = 0,
v8::Local<v8::Value> argv[] = 0) const;
v8::Local<v8::Value> Call(v8::Local<v8::Object> target,
int argc,
v8::Local<v8::Value> argv[]) const;
v8::Local<v8::Value> Call(int argc, v8::Local<v8::Value> argv[]) const;
};
```
Example usage:
```c++
v8::Local<v8::Function> function;
Nan::Callback callback(function);
callback.Call(0, 0);

## Converters
NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
- <a href="#api_nan_to"><b><code>Nan::To()</code></b></a>
<a name="api_nan_to"></a>
### Nan::To()
Converts a `v8::Local<v8::Value>` to a different subtype of `v8::Value` or to a native data type. Returns a `Nan::MaybeLocal<>` or a `Nan::Maybe<>` accordingly.
See [maybe_types.md](./maybe_types.md) for more information on `Nan::Maybe` types.
Signatures:
```c++
// V8 types
Nan::MaybeLocal<v8::Boolean> Nan::To<v8::Boolean>(v8::Local<v8::Value> val);
Nan::MaybeLocal<v8::Int32> Nan::To<v8::Int32>(v8::Local<v8::Value> val);
Nan::MaybeLocal<v8::Integer> Nan::To<v8::Integer>(v8::Local<v8::Value> val);
Nan::MaybeLocal<v8::Object> Nan::To<v8::Object>(v8::Local<v8::Value> val);
Nan::MaybeLocal<v8::Number> Nan::To<v8::Number>(v8::Local<v8::Value> val);
Nan::MaybeLocal<v8::String> Nan::To<v8::String>(v8::Local<v8::Value> val);
Nan::MaybeLocal<v8::Uint32> Nan::To<v8::Uint32>(v8::Local<v8::Value> val);
// Native types
Nan::Maybe<bool> Nan::To<bool>(v8::Local<v8::Value> val);
Nan::Maybe<double> Nan::To<double>(v8::Local<v8::Value> val);
Nan::Maybe<int32_t> Nan::To<int32_t>(v8::Local<v8::Value> val);
Nan::Maybe<int64_t> Nan::To<int64_t>(v8::Local<v8::Value> val);
Nan::Maybe<uint32_t> Nan::To<uint32_t>(v8::Local<v8::Value> val);

Nan::MaybeLocal<v8::String> str = Nan::To<v8::String>(val);
Nan::Maybe<double> d = Nan::To<double>(val);

### Nan::MaybeLocal
A `Nan::MaybeLocal<T>` is a wrapper around [`v8::Local<T>`](https://v8docs.nodesource.com/node-8.16/de/deb/classv8_1_1_local.html) that enforces a check that determines whether the `v8::Local<T>` is empty before it can be used.
If an API method returns a `Nan::MaybeLocal`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, an empty `Nan::MaybeLocal` is returned.
Definition:
```c++
template<typename T> class Nan::MaybeLocal {
public:
MaybeLocal();
template<typename S> MaybeLocal(v8::Local<S> that);
bool IsEmpty() const;
template<typename S> bool ToLocal(v8::Local<S> *out);
// Will crash if the MaybeLocal<> is empty.
v8::Local<T> ToLocalChecked();
template<typename S> v8::Local<S> FromMaybe(v8::Local<S> default_value) const;
};
```
See the documentation for [`v8::MaybeLocal`](https://v8docs.nodesource.com/node-8.16/d8/d7d/classv8_1_1_maybe_local.html) for further details.
<a name="api_nan_maybe"></a>
### Nan::Maybe
A simple `Nan::Maybe` type, representing an object which may or may not have a value, see https://hackage.haskell.org/package/base/docs/Data-Maybe.html.
If an API method returns a `Nan::Maybe<>`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, a "Nothing" value is returned.

## JavaScript-accessible methods
A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

### Nan::FunctionCallbackInfo
`Nan::FunctionCallbackInfo` should be used in place of [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html), even with older versions of Node where `v8::FunctionCallbackInfo` does not exist.
Definition:
```c++
template<typename T> class FunctionCallbackInfo {
public:
ReturnValue<T> GetReturnValue() const;
v8::Local<v8::Function> Callee(); // NOTE: Not available in NodeJS >= 10.0.0
v8::Local<v8::Value> Data();
v8::Local<v8::Object> Holder();
bool IsConstructCall();
int Length() const;
v8::Local<v8::Value> operator[](int i) const;
v8::Local<v8::Object> This() const;
v8::Isolate *GetIsolate() const;
};
```
See the [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from methods.
**Note:** `FunctionCallbackInfo::Callee` is removed in Node.js after `10.0.0` because it is was deprecated in V8. Consider using `info.Data()` to pass any information you need.

`Nan::PropertyCallbackInfo` should be used in place of [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html), even with older versions of Node where `v8::PropertyCallbackInfo` does not exist.
Definition:
```c++
template<typename T> class PropertyCallbackInfo : public PropertyCallbackInfoBase<T> {
public:
ReturnValue<T> GetReturnValue() const;
v8::Isolate* GetIsolate() const;
v8::Local<v8::Value> Data() const;
v8::Local<v8::Object> This() const;
v8::Local<v8::Object> Holder() const;
};
```
See the [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from property accessor methods.
<a name="api_nan_return_value"></a>
### Nan::ReturnValue
`Nan::ReturnValue` is used in place of [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.16/da/da7/classv8_1_1_return_value.html) on both [`Nan::FunctionCallbackInfo`](#api_nan_function_callback_info) and [`Nan::PropertyCallbackInfo`](#api_nan_property_callback_info) as the return type of `GetReturnValue()`.
Example usage:
```c++
void EmptyArray(const Nan::FunctionCallbackInfo<v8::Value>& info) {
info.GetReturnValue().Set(Nan::New<v8::Array>());
}
```
Definition:
```c++
template<typename T> class ReturnValue {
public:
// Handle setters
template <typename S> void Set(const v8::Local<S> &handle);
template <typename S> void Set(const Nan::Global<S> &handle);
// Fast primitive setters
void Set(bool value);
void Set(double i);
void Set(int32_t i);
void Set(uint32_t i);
// Fast JS primitive setters
void SetNull();
void SetUndefined();
void SetEmptyString();
// Convenience getter for isolate
v8::Isolate *GetIsolate() const;
};
```
See the documentation on [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.16/da/da7/classv8_1_1_return_value.html) for further information on this.
<a name="api_nan_method"></a>
### Method declaration
JavaScript-accessible methods should be declared with the following signature to form a `Nan::FunctionCallback`:
```c++
typedef void(*FunctionCallback)(const FunctionCallbackInfo<v8::Value>&);
```
Example:
```c++
void MethodName(const Nan::FunctionCallbackInfo<v8::Value>& info) {
...
}
```
You do not need to declare a new `HandleScope` within a method as one is implicitly created for you.
**Example usage**
```c++
// .h:
class Foo : public Nan::ObjectWrap {
...
static void Bar(const Nan::FunctionCallbackInfo<v8::Value>& info);
static void Baz(const Nan::FunctionCallbackInfo<v8::Value>& info);
}
// .cc:
void Foo::Bar(const Nan::FunctionCallbackInfo<v8::Value>& info) {
...
}
void Foo::Baz(const Nan::FunctionCallbackInfo<v8::Value>& info) {
...
}
```
A helper macro `NAN_METHOD(methodname)` exists, compatible with NAN v1 method declarations.
**Example usage with `NAN_METHOD(methodname)`**
```c++
// .h:
class Foo : public Nan::ObjectWrap {
...
static NAN_METHOD(Bar);
static NAN_METHOD(Baz);
}
// .cc:
NAN_METHOD(Foo::Bar) {
...
}
NAN_METHOD(Foo::Baz) {
...
}
```
Use [`Nan::SetPrototypeMethod`](#api_nan_set_prototype_method) to attach a method to a JavaScript function prototype or [`Nan::SetMethod`](#api_nan_set_method) to attach a method directly on a JavaScript object.

## New
NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.

<a name="api_nan_new"></a>
### Nan::New()
`Nan::New()` should be used to instantiate new JavaScript objects.
Refer to the specific V8 type in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/d1/d83/classv8_1_1_data.html) for information on the types of arguments required for instantiation.
Signatures:
Return types are mostly omitted from the signatures for simplicity. In most cases the type will be contained within a `v8::Local<T>`. The following types will be contained within a `Nan::MaybeLocal<T>`: `v8::String`, `v8::Date`, `v8::RegExp`, `v8::Script`, `v8::UnboundScript`.
Empty objects:
```c++
Nan::New<T>();
```
Generic single and multiple-argument:
```c++
Nan::New<T>(A0 arg0);
Nan::New<T>(A0 arg0, A1 arg1);
Nan::New<T>(A0 arg0, A1 arg1, A2 arg2);
Nan::New<T>(A0 arg0, A1 arg1, A2 arg2, A3 arg3);
```
For creating `v8::FunctionTemplate` and `v8::Function` objects:
_The definition of `Nan::FunctionCallback` can be found in the [Method declaration](./methods.md#api_nan_method) documentation._
```c++
Nan::New<T>(Nan::FunctionCallback callback,
v8::Local<v8::Value> data = v8::Local<v8::Value>());
Nan::New<T>(Nan::FunctionCallback callback,
v8::Local<v8::Value> data = v8::Local<v8::Value>(),
A2 a2 = A2());
```
Native number types:
```c++
v8::Local<v8::Boolean> Nan::New<T>(bool value);
v8::Local<v8::Int32> Nan::New<T>(int32_t value);
v8::Local<v8::Uint32> Nan::New<T>(uint32_t value);
v8::Local<v8::Number> Nan::New<T>(double value);
```
String types:
```c++
Nan::MaybeLocal<v8::String> Nan::New<T>(std::string const& value);
Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value, int length);
Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value);
Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value);
Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value, int length);
```
Specialized types:
```c++
v8::Local<v8::String> Nan::New<T>(v8::String::ExternalStringResource * value);
v8::Local<v8::String> Nan::New<T>(Nan::ExternalOneByteStringResource * value);
v8::Local<v8::RegExp> Nan::New<T>(v8::Local<v8::String> pattern, v8::RegExp::Flags flags);
```
Note that `Nan::ExternalOneByteStringResource` maps to [`v8::String::ExternalOneByteStringResource`](https://v8docs.nodesource.com/node-8.16/d9/db3/classv8_1_1_string_1_1_external_one_byte_string_resource.html), and `v8::String::ExternalAsciiStringResource` in older versions of V8.

### Nan::AsyncResource
This class is analogous to the `AsyncResource` JavaScript class exposed by Node's [async_hooks][] API.
When calling back into JavaScript asynchronously, special care must be taken to ensure that the runtime can properly track
async hops. `Nan::AsyncResource` is a class that provides an RAII wrapper around `node::EmitAsyncInit`, `node::EmitAsyncDestroy`,
and `node::MakeCallback`. Using this mechanism to call back into JavaScript, as opposed to `Nan::MakeCallback` or
`v8::Function::Call` ensures that the callback is executed in the correct async context. This ensures that async mechanisms
such as domains and [async_hooks][] function correctly.
Definition:
```c++
class AsyncResource {
public:
AsyncResource(v8::Local<v8::String> name,
v8::Local<v8::Object> resource = New<v8::Object>());
AsyncResource(const char* name,
v8::Local<v8::Object> resource = New<v8::Object>());
~AsyncResource();
v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
v8::Local<v8::Function> func,
int argc,
v8::Local<v8::Value>* argv);
v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
v8::Local<v8::String> symbol,
int argc,
v8::Local<v8::Value>* argv);
v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
const char* method,
int argc,
v8::Local<v8::Value>* argv);
};
```
* `name`: Identifier for the kind of resource that is being provided for diagnostics information exposed by the [async_hooks][]
API. This will be passed to the possible `init` hook as the `type`. To avoid name collisions with other modules we recommend
that the name include the name of the owning module as a prefix. For example `mysql` module could use something like
`mysql:batch-db-query-resource`.
* `resource`: An optional object associated with the async work that will be passed to the possible [async_hooks][]
`init` hook. If this parameter is omitted, or an empty handle is provided, this object will be created automatically.
* When calling JS on behalf of this resource, one can use `runInAsyncScope`. This will ensure that the callback runs in the
correct async execution context.
* `AsyncDestroy` is automatically called when an AsyncResource object is destroyed.
For more details, see the Node [async_hooks][] documentation. You might also want to take a look at the documentation for the
[N-API counterpart][napi]. For example usage, see the `asyncresource.cpp` example in the `test/cpp` directory.
<a name="api_nan_make_callback"></a>
### Nan::MakeCallback()
Deprecated wrappers around the legacy `node::MakeCallback()` APIs. Node.js 10+
has deprecated these legacy APIs as they do not provide a mechanism to preserve
async context.
We recommend that you use the `AsyncResource` class and `AsyncResource::runInAsyncScope` instead of using `Nan::MakeCallback` or
`v8::Function#Call()` directly. `AsyncResource` properly takes care of running the callback in the correct async execution
context – something that is essential for functionality like domains, async_hooks and async debugging.
Signatures:
```c++
NAN_DEPRECATED
v8::Local<v8::Value> Nan::MakeCallback(v8::Local<v8::Object> target,
v8::Local<v8::Function> func,
int argc,
v8::Local<v8::Value>* argv);
NAN_DEPRECATED
v8::Local<v8::Value> Nan::MakeCallback(v8::Local<v8::Object> target,
v8::Local<v8::String> symbol,
int argc,
v8::Local<v8::Value>* argv);
NAN_DEPRECATED
v8::Local<v8::Value> Nan::MakeCallback(v8::Local<v8::Object> target,
const char* method,
int argc,
v8::Local<v8::Value>* argv);
```
<a name="api_nan_module_init"></a>
### NAN_MODULE_INIT()
Used to define the entry point function to a Node add-on. Creates a function with a given `name` that receives a `target` object representing the equivalent of the JavaScript `exports` object.
See example below.
<a name="api_nan_export"></a>
### Nan::Export()
A simple helper to register a `v8::FunctionTemplate` from a JavaScript-accessible method (see [Methods](./methods.md)) as a property on an object. Can be used in a way similar to assigning properties to `module.exports` in JavaScript.
Signature:
```c++
void Export(v8::Local<v8::Object> target, const char *name, Nan::FunctionCallback f)
```
Also available as the shortcut `NAN_EXPORT` macro.
Example:
```c++
NAN_METHOD(Foo) {
...
}
NAN_MODULE_INIT(Init) {
NAN_EXPORT(target, Foo);
}
```

## Object Wrappers
The `ObjectWrap` class can be used to make wrapped C++ objects and a factory of wrapped objects.
- <a href="#api_nan_object_wrap"><b><code>Nan::ObjectWrap</code></b></a>
<a name="api_nan_object_wrap"></a>
### Nan::ObjectWrap()
A reimplementation of `node::ObjectWrap` that adds some API not present in older versions of Node. Should be preferred over `node::ObjectWrap` in all cases for consistency.
Definition:
```c++
class ObjectWrap {
public:
ObjectWrap();
virtual ~ObjectWrap();
template <class T>
static inline T* Unwrap(v8::Local<v8::Object> handle);
inline v8::Local<v8::Object> handle();
inline Nan::Persistent<v8::Object>& persistent();
protected:
inline void Wrap(v8::Local<v8::Object> handle);
inline void MakeWeak();
/* Ref() marks the object as being attached to an event loop.
* Refed objects will not be garbage collected, even if
* all references are lost.
*/
virtual void Ref();
/* Unref() marks an object as detached from the event loop. This is its
* default state. When an object with a "weak" reference changes from
* attached to detached state it will be freed. Be careful not to access
* the object after making this call as it might be gone!
* (A "weak reference" means an object that only has a
* persistent handle.)
*
* DO NOT CALL THIS FROM DESTRUCTOR
*/
virtual void Unref();
int refs_; // ro
};
```
See the Node documentation on [Wrapping C++ Objects](https://nodejs.org/api/addons.html#addons_wrapping_c_objects) for more details.
### This vs. Holder
When calling `Unwrap`, it is important that the argument is indeed some JavaScript object which got wrapped by a `Wrap` call for this class or any derived class.
The `Signature` installed by [`Nan::SetPrototypeMethod()`](methods.md#api_nan_set_prototype_method) does ensure that `info.Holder()` is just such an instance.
In Node 0.12 and later, `info.This()` will also be of such a type, since otherwise the invocation will get rejected.
However, in Node 0.10 and before it was possible to invoke a method on a JavaScript object which just had the extension type in its prototype chain.
In such a situation, calling `Unwrap` on `info.This()` will likely lead to a failed assertion causing a crash, but could lead to even more serious corruption.
On the other hand, calling `Unwrap` in an [accessor](methods.md#api_nan_set_accessor) should not use `Holder()` if the accessor is defined on the prototype.
So either define your accessors on the instance template,
or use `This()` after verifying that it is indeed a valid object.
### Examples
#### Basic
```c++
class MyObject : public Nan::ObjectWrap {
public:
static NAN_MODULE_INIT(Init) {
v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);
tpl->SetClassName(Nan::New("MyObject").ToLocalChecked());
tpl->InstanceTemplate()->SetInternalFieldCount(1);
Nan::SetPrototypeMethod(tpl, "getHandle", GetHandle);
Nan::SetPrototypeMethod(tpl, "getValue", GetValue);
constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
Nan::Set(target, Nan::New("MyObject").ToLocalChecked(),
Nan::GetFunction(tpl).ToLocalChecked());
}
private:
explicit MyObject(double value = 0) : value_(value) {}
~MyObject() {}
static NAN_METHOD(New) {
if (info.IsConstructCall()) {
double value = info[0]->IsUndefined() ? 0 : Nan::To<double>(info[0]).FromJust();
MyObject *obj = new MyObject(value);
obj->Wrap(info.This());
info.GetReturnValue().Set(info.This());
} else {
const int argc = 1;
v8::Local<v8::Value> argv[argc] = {info[0]};
v8::Local<v8::Function> cons = Nan::New(constructor());
info.GetReturnValue().Set(Nan::NewInstance(cons, argc, argv).ToLocalChecked());
}
}
static NAN_METHOD(GetHandle) {
MyObject* obj = Nan::ObjectWrap::Unwrap<MyObject>(info.Holder());
info.GetReturnValue().Set(obj->handle());
}
static NAN_METHOD(GetValue) {
MyObject* obj = Nan::ObjectWrap::Unwrap<MyObject>(info.Holder());
info.GetReturnValue().Set(obj->value_);
}
static inline Nan::Persistent<v8::Function> & constructor() {
static Nan::Persistent<v8::Function> my_constructor;
return my_constructor;
}
double value_;
};
NODE_MODULE(objectwrapper, MyObject::Init)
```
To use in Javascript:
```Javascript
var objectwrapper = require('bindings')('objectwrapper');
var obj = new objectwrapper.MyObject(5);
console.log('Should be 5: ' + obj.getValue());
```
#### Factory of wrapped objects
```c++
class MyFactoryObject : public Nan::ObjectWrap {
public:
static NAN_MODULE_INIT(Init) {
v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);
tpl->InstanceTemplate()->SetInternalFieldCount(1);
Nan::SetPrototypeMethod(tpl, "getValue", GetValue);
constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
}
static NAN_METHOD(NewInstance) {
v8::Local<v8::Function> cons = Nan::New(constructor());
double value = info[0]->IsNumber() ? Nan::To<double>(info[0]).FromJust() : 0;
const int argc = 1;
v8::Local<v8::Value> argv[1] = {Nan::New(value)};
info.GetReturnValue().Set(Nan::NewInstance(cons, argc, argv).ToLocalChecked());
}
// Needed for the next example:
inline double value() const {
return value_;
}
private:
explicit MyFactoryObject(double value = 0) : value_(value) {}
~MyFactoryObject() {}
static NAN_METHOD(New) {
if (info.IsConstructCall()) {
double value = info[0]->IsNumber() ? Nan::To<double>(info[0]).FromJust() : 0;
MyFactoryObject * obj = new MyFactoryObject(value);
obj->Wrap(info.This());
info.GetReturnValue().Set(info.This());
} else {
const int argc = 1;
v8::Local<v8::Value> argv[argc] = {info[0]};
v8::Local<v8::Function> cons = Nan::New(constructor());
info.GetReturnValue().Set(Nan::NewInstance(cons, argc, argv).ToLocalChecked());
}
}
static NAN_METHOD(GetValue) {
MyFactoryObject* obj = ObjectWrap::Unwrap<MyFactoryObject>(info.Holder());
info.GetReturnValue().Set(obj->value_);
}
static inline Nan::Persistent<v8::Function> & constructor() {
static Nan::Persistent<v8::Function> my_constructor;
return my_constructor;
}
double value_;
};
NAN_MODULE_INIT(Init) {
MyFactoryObject::Init(target);
Nan::Set(target,
Nan::New<v8::String>("newFactoryObjectInstance").ToLocalChecked(),
Nan::GetFunction(
Nan::New<v8::FunctionTemplate>(MyFactoryObject::NewInstance)).ToLocalChecked()
);
}
NODE_MODULE(wrappedobjectfactory, Init)
```
To use in Javascript:
```Javascript
var wrappedobjectfactory = require('bindings')('wrappedobjectfactory');
var obj = wrappedobjectfactory.newFactoryObjectInstance(10);
console.log('Should be 10: ' + obj.getValue());
```
#### Passing wrapped objects around
Use the `MyFactoryObject` class above along with the following:
```c++
static NAN_METHOD(Sum) {
Nan::MaybeLocal<v8::Object> maybe1 = Nan::To<v8::Object>(info[0]);
Nan::MaybeLocal<v8::Object> maybe2 = Nan::To<v8::Object>(info[1]);
// Quick check:
if (maybe1.IsEmpty() || maybe2.IsEmpty()) {
// return value is undefined by default
return;
}
MyFactoryObject* obj1 =
Nan::ObjectWrap::Unwrap<MyFactoryObject>(maybe1.ToLocalChecked());
MyFactoryObject* obj2 =
Nan::ObjectWrap::Unwrap<MyFactoryObject>(maybe2.ToLocalChecked());
info.GetReturnValue().Set(Nan::New<v8::Number>(obj1->value() + obj2->value()));
}
NAN_MODULE_INIT(Init) {
MyFactoryObject::Init(target);
Nan::Set(target,
Nan::New<v8::String>("newFactoryObjectInstance").ToLocalChecked(),
Nan::GetFunction(
Nan::New<v8::FunctionTemplate>(MyFactoryObject::NewInstance)).ToLocalChecked()
);
Nan::Set(target,
Nan::New<v8::String>("sum").ToLocalChecked(),
Nan::GetFunction(Nan::New<v8::FunctionTemplate>(Sum)).ToLocalChecked()
);
}
NODE_MODULE(myaddon, Init)
```
To use in Javascript:
```Javascript
var myaddon = require('bindings')('myaddon');
var obj1 = myaddon.newFactoryObjectInstance(5);
var obj2 = myaddon.newFactoryObjectInstance(10);
console.log('sum of object values: ' + myaddon.sum(obj1, obj2));

## Persistent references
An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

### Nan::PersistentBase & v8::PersistentBase
A persistent handle contains a reference to a storage cell in V8 which holds an object value and which is updated by the garbage collector whenever the object is moved. A new storage cell can be created using the constructor or `Nan::PersistentBase::Reset()`. Existing handles can be disposed using an argument-less `Nan::PersistentBase::Reset()`.

_(note: this is implemented as `Nan::PersistentBase` for older versions of V8 and the native `v8::PersistentBase` is used for newer versions of V8)_

Persistent &operator=(const Persistent &that);
template <typename S, typename M2>
Persistent &operator=(const Persistent<S, M2> &that);
/**
* The destructor will dispose the Persistent based on the kResetInDestructor

### Nan::Global
A type of `PersistentBase` which has move semantics.
```c++
template<typename T> class Global : public PersistentBase<T> {
public:
/**
* A Global with no storage cell.
*/
Global();
/**
* Construct a Global from a v8::Local. When the v8::Local is non-empty, a new

<a name="api_nan_weak_callback_info"></a>
### Nan::WeakCallbackInfo
`Nan::WeakCallbackInfo` is used as an argument when setting a persistent reference as weak. You may need to free any external resources attached to the object. It is a mirror of `v8:WeakCallbackInfo` as found in newer versions of V8.
Definition:
```c++
template<typename T> class WeakCallbackInfo {
public:
typedef void (*Callback)(const WeakCallbackInfo<T>& data);
v8::Isolate *GetIsolate() const;
/**
* Get the parameter that was associated with the weak handle.
*/
T *GetParameter() const;
/**
* Get pointer from internal field, index can be 0 or 1.
*/
void *GetInternalField(int index) const;
};
```
Example usage:
```c++
void weakCallback(const WeakCallbackInfo<int> &data) {
int *parameter = data.GetParameter();
delete parameter;
}
Persistent<v8::Object> obj;
int *data = new int(0);
obj.SetWeak(data, callback, WeakCallbackType::kParameter);
```
See the V8 documentation for [`WeakCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d8/d06/classv8_1_1_weak_callback_info.html) for further information.
<a name="api_nan_weak_callback_type"></a>
### Nan::WeakCallbackType
Represents the type of a weak callback.
A weak callback of type `kParameter` makes the supplied parameter to `Nan::PersistentBase::SetWeak` available through `WeakCallbackInfo::GetParameter`.
A weak callback of type `kInternalFields` uses up to two internal fields at indices 0 and 1 on the `Nan::PersistentBase<v8::Object>` being made weak.
Note that only `v8::Object`s and derivatives can have internal fields.
Definition:
```c++
enum class WeakCallbackType { kParameter, kInternalFields };
```

## Scopes
A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.

Allocate a new `Nan::HandleScope` whenever you are creating new V8 JavaScript objects. Note that an implicit `HandleScope` is created for you on JavaScript-accessible methods so you do not need to insert one yourself.
Example:
```c++
// new object is created, it needs a new scope:
void Pointless() {
Nan::HandleScope scope;
v8::Local<v8::Object> obj = Nan::New<v8::Object>();
}
// JavaScript-accessible method already has a HandleScope
NAN_METHOD(Pointless2) {
v8::Local<v8::Object> obj = Nan::New<v8::Object>();
}
```
<a name="api_nan_escapable_handle_scope"></a>
### Nan::EscapableHandleScope
Similar to [`Nan::HandleScope`](#api_nan_handle_scope) but should be used in cases where a function needs to return a V8 JavaScript type that has been created within it.
Definition:
```c++
class Nan::EscapableHandleScope {
public:
Nan::EscapableHandleScope();
static int NumberOfHandles();
template<typename T> v8::Local<T> Escape(v8::Local<T> value);
}
```
Use `Escape(value)` to return the object.
Example:
```c++
v8::Local<v8::Object> EmptyObj() {
Nan::EscapableHandleScope scope;
v8::Local<v8::Object> obj = Nan::New<v8::Object>();
return scope.Escape(obj);
}
```

## Script
NAN provides `v8::Script` helpers as the API has changed over the supported versions of V8.

- <a href="#api_nan_run_script"><b><code>Nan::RunScript()</code></b></a>
- <a href="#api_nan_script_origin"><b><code>Nan::ScriptOrigin</code></b></a>
<a name="api_nan_compile_script"></a>
### Nan::CompileScript()
A wrapper around [`v8::ScriptCompiler::Compile()`](https://v8docs.nodesource.com/node-8.16/da/da5/classv8_1_1_script_compiler.html#a93f5072a0db55d881b969e9fc98e564b).
Note that `Nan::BoundScript` is an alias for `v8::Script`.
Signature:
```c++
Nan::MaybeLocal<Nan::BoundScript> Nan::CompileScript(
v8::Local<v8::String> s,
const v8::ScriptOrigin& origin);
Nan::MaybeLocal<Nan::BoundScript> Nan::CompileScript(v8::Local<v8::String> s);
```
<a name="api_nan_run_script"></a>
### Nan::RunScript()
Calls `script->Run()` or `script->BindToCurrentContext()->Run(Nan::GetCurrentContext())`.
Note that `Nan::BoundScript` is an alias for `v8::Script` and `Nan::UnboundScript` is an alias for `v8::UnboundScript` where available and `v8::Script` on older versions of V8.
Signature:
```c++
Nan::MaybeLocal<v8::Value> Nan::RunScript(v8::Local<Nan::UnboundScript> script)
Nan::MaybeLocal<v8::Value> Nan::RunScript(v8::Local<Nan::BoundScript> script)
```
<a name="api_nan_script_origin"></a>
### Nan::ScriptOrigin
A class transparently extending [`v8::ScriptOrigin`](https://v8docs.nodesource.com/node-16.0/db/d84/classv8_1_1_script_origin.html#pub-methods)
to provide backwards compatibility. Only the listed methods are guaranteed to
be available on all versions of Node.
Declaration:
```c++
class Nan::ScriptOrigin : public v8::ScriptOrigin {
public:
ScriptOrigin(v8::Local<v8::Value> name, v8::Local<v8::Integer> line = v8::Local<v8::Integer>(), v8::Local<v8::Integer> column = v8::Local<v8::Integer>())
v8::Local<v8::Value> ResourceName() const;
v8::Local<v8::Integer> ResourceLineOffset() const;
v8::Local<v8::Integer> ResourceColumnOffset() const;
}

### Nan::Utf8String
Converts an object to a UTF-8-encoded character array. If conversion to a string fails (e.g. due to an exception in the toString() method of the object) then the length() method returns 0 and the * operator returns NULL. The underlying memory used for this object is managed by the object.
An implementation of [`v8::String::Utf8Value`](https://v8docs.nodesource.com/node-8.16/d4/d1b/classv8_1_1_string_1_1_utf8_value.html) that is consistent across all supported versions of V8.
Definition:
```c++
class Nan::Utf8String {
public:
Nan::Utf8String(v8::Local<v8::Value> from);
int length() const;
char* operator*();
const char* operator*() const;
};
```
<a name="api_nan_get_current_context"></a>
### Nan::GetCurrentContext()
A call to [`v8::Isolate::GetCurrent()->GetCurrentContext()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#a81c7a1ed7001ae2a65e89107f75fd053) that works across all supported versions of V8.
Signature:
```c++
v8::Local<v8::Context> Nan::GetCurrentContext()
```
<a name="api_nan_set_isolate_data"></a>
### Nan::SetIsolateData()
A helper to provide a consistent API to [`v8::Isolate#SetData()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#a7acadfe7965997e9c386a05f098fbe36).
Signature:
```c++
void Nan::SetIsolateData(v8::Isolate *isolate, T *data)
```
<a name="api_nan_get_isolate_data"></a>
### Nan::GetIsolateData()
A helper to provide a consistent API to [`v8::Isolate#GetData()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#aabd223436bc1100a787dadaa024c6257).
Signature:
```c++
T *Nan::GetIsolateData(v8::Isolate *isolate)
```
<a name="api_nan_typedarray_contents"></a>
### Nan::TypedArrayContents<T>
A helper class for accessing the contents of an ArrayBufferView (aka a typedarray) from C++. If the input array is not a valid typedarray, then the data pointer of TypedArrayContents will default to `NULL` and the length will be 0. If the data pointer is not compatible with the alignment requirements of type, an assertion error will fail.
Note that you must store a reference to the `array` object while you are accessing its contents.
Definition:
```c++
template<typename T>
class Nan::TypedArrayContents {
public:
TypedArrayContents(v8::Local<Value> array);
size_t length() const;
T* const operator*();
const T* const operator*() const;
};
