* feat(runtime): embed goja + esbuild; add ZAP-over-HTTP transport
Establish zip as the canonical Hanzo Go web framework with embedded
in-process JS execution and a native ZAP RPC HTTP transport. One Go
binary mounts native handlers, legacy TS/JS handlers, WebSocket, and
the ZAP RPC plane — no separate runtime service, no inter-service RPC,
no container-per-service.
zip/runtime/ (new):
- jsvm.go NewJSRuntime / Eval / RegisterHostFn / LoadModule, backed
by a pool of *goja.Runtime (pure Go, no CGO). Pool pattern
lifted from hanzoai/base/plugins/gojavm, slimmed to run +
forEach so late host-fn / module registration reaches warm
VMs.
- pool.go fixed-size goja VM pool; saturated calls fall back to a
fully-provisioned one-off VM.
- require.go CommonJS-style require(): per-VM module sources + memoized
exports in a Go-side side-table (never visible to JS).
- esbuild.go TranspileToES5: TS/modern-JS -> goja-ready JS via esbuild's
pure-Go API (ES2015 target, CommonJS format).
- handler.go JSHandler / JSModule: mount an Express-shaped (req, res) JS
function as a fiber.Handler; req mirrors method/path/query/
headers/body, res mirrors status/set/json/send.
- json.go encode/decode through internal/jsonenc — one wire format.
zip/zaprpc/ (new on existing Registry seam):
- envelope.go canonical ZAP RPC frame (service/method/payload) over the
zap-proto/go wire codec.
- http.go HTTPHandler(reg): serves the ZAP RPC plane over HTTP POST;
binary envelope canonical, X-ZAP-* headers are a hint only.
examples/express-in-zip/ (new): legacy app.ts -> real esbuild -> real
goja -> real Fiber -> real HTTP, with an integration test proving
GET /legacy/foo and POST /legacy/bar body echo.
README: embedded-JS migration path + single-binary (HIP-0106) sections.
go build ./... and go test ./... (incl. -race) pass.
* feat(runtime): ctx-aware Eval + multi-file BundleToES2015
Two consumer-integration follow-ups so callers (base's gojavm) stop
reaching past the runtime abstraction.
EvalContext(ctx, src): interrupt a running goja VM when ctx fires.
A watcher goroutine calls vm.Interrupt(ctx.Err()) on ctx.Done(); the
resulting *goja.InterruptedError is unwrapped back to ctx.Err(). The
watcher is joined and ClearInterrupt() is called before the VM is
returned to the pool, so a borrowed VM is never left interrupted.
Eval routes through EvalContext(context.Background()). InvokeFunc(ctx,
fnName, args...) calls a named global JS function under the same
cancellation discipline. This lets base drop the goroutine+timeout race
around Invoke.
BundleToES2015(entry, files, opts): transpile + bundle a multi-file
TS/JS tree from an in-memory files map using esbuild's pure-Go Build
API with an onResolve/onLoad plugin serving a virtual namespace — no
real FS access, no CGO. Relative imports resolve against the importer's
dir; opts.External keeps bare specifiers as require()/import calls for
goja to resolve at runtime. This replaces consumers importing esbuild's
api package directly to bundle.
Tests (go test -race clean):
- EvalContext(50ms, while(true){}) returns DeadlineExceeded in ~50ms
- successful eval returns the value; VM reusable afterwards
- two-file CommonJS bundle runs in goja, entry.run() === 42
- external dep stays require("external") and resolves via host module
* feat(runtime): unified multi-language Runner over the extruntime SPI
Add Runner — a registry of language → Engine that executes arbitrary-
language source in goroutine-scoped, context.Context-bound tasks. Each
Run spawns a worker (engine.Eval) and a watcher (ctx.Done() → engine
interrupt), joining both before return so a borrowed VM is never handed
back to its pool while still interrupted. This generalizes the settled
JSRuntime.EvalContext cancellation contract (one worker, one watcher,
joined, engine-specific interrupt) across every backend a host registers.
zip ships exactly one in-tree engine: the pure-Go goja engine, surfaced
via (*JSRuntime).Engine() and registered as "js". It self-manages ctx
inside EvalContext (per-call interrupt on the exact borrowed VM), so the
Runner's watcher is a benign no-op for it. base's backends (pyvm, v8vm,
wasmvm, starkvm) plug in through the same Engine seam via thin extruntime
adapters at app startup — the registry is the seam, not an import edge.
zip never imports base; the dependency direction stays base → zip.
Engine is the zip-side projection of base's extruntime backends: any
value implementing Eval(ctx, src, args) satisfies it. Optional
Interruptible lets the watcher abort a runaway eval out-of-band.
Wire the unified runner into examples/express-in-zip: POST /runtime/:lang
reads the body as source, dispatches to the engine for :lang, returns
{result} or 404 {error:"unknown language"}.
Tests (go test -race, all green):
- JS happy path: Run(ctx, "js", "1+2") → int64(3)
- JS function call: define + invoke in one eval
- JS ctx deadline: while(true){} interrupted, DeadlineExceeded, ~50ms
- unknown language: ErrUnknownLanguage sentinel, no panic
- concurrent: 100 goroutines, registry RWMutex + per-call VM isolation
- example: POST /runtime/js "40+2" → {"result":42}; cobol → 404
No cgo. No base import. README documents the Runner + SPI registration.
