* Rename lower case isomorphic default exports modules to upper case named exports
We're somewhat inconsistent here between e.g. ReactLazy and memo.
Let's pick one.
This also moves the responder, fundamental, scope creators from shared
since they're isomorphic and same as the other creators.
* Move some files that are specific to the react-reconciler from shared
Individual renderers are allowed to deep require into the reconciler.
* Move files specific to react-dom from shared
react-interactions is right now dom specific (it wasn't before) so we can
type check it together with other dom stuff. Avoids the need for
a shared ReactDOMTypes to be checked by RN for example.
* Move ReactWorkTags to the reconciler
* Move createPortal to export from reconciler
Otherwise Noop can't access it since it's not allowed deep requires.
* Added missing @flow pragma to React.js
* Fixed useContext() return type definition
* Fixed previously masked Flow errors in DevTools and react-interactions packages
* Added displayName to internal Context Flow type
* Removed Flow generic annotations for createResponder
This seems to cause a parsing error. (Not sure why.) The API is deprecated anyway so I'm being lazy for now and just adding a .
* Move remaining things to named exports
The interesting case here is the noop renderers. The wrappers around the
reconciler now changed to use a local export that gets mutated.
ReactNoop and ReactNoopPersistent now have to destructure the object to
list out the names it's going to export. We should probably refactor
ReactNoop away from createReactNoop. Especially since it's also not Flow
typed.
* Switch interactions to star exports
This will have esModule compatibility flag on them. They should ideally
export default instead.
* Add options for forked entry points
We currently fork .fb.js entry points. This adds a few more options.
.modern.fb.js - experimental FB builds
.classic.fb.js - stable FB builds
.fb.js - if no other FB build, use this for FB builds
.experimental.js - experimental builds
.stable.js - stable builds
.js - used if no other override exists
This will be used to have different ES exports for different builds.
* Switch React to named exports
* Export named exports from the export point itself
We need to re-export the Flow exported types so we can use them in our code.
We don't want to use the Flow types from upstream since it doesn't have the non-public APIs that we have.
This should be able to use export * but I don't know why it doesn't work.
This actually enables Flow typing of React which was just "any" before.
This exposed some Flow errors that needs fixing.
* Create forks for the react entrypoint
None of our builds expose all exports and they all differ in at least one
way, so we need four forks.
* Set esModule flag to false
We don't want to emit the esModule compatibility flag on our CommonJS
output. For now we treat our named exports as if they're CommonJS.
This is a potentially breaking change for scheduler (but all those apis
are unstable), react-is and use-subscription. However, it seems unlikely
that anyone would rely on this since these only have named exports.
* Remove unused Feature Flags
* Let jest observe the stable fork for stable tests
This lets it do the negative test by ensuring that the right tests fail.
However, this in turn will make other tests that are not behind
__EXPERIMENTAL__ fail. So I need to do that next.
* Put all tests that depend on exports behind __EXPERIMENTAL__
Since there's no way to override the exports using feature flags
in .intern.js anymore we can't use these APIs in stable.
The tradeoff here is that we can either enable the negative tests on
"stable" that means experimental are expected to fail, or we can disable
tests on stable. This is unfortunate since some of these APIs now run on
a "stable" config at FB instead of the experimental.
* Switch ReactDOM to named exports
Same strategy as React.
I moved the ReactDOMFB runtime injection to classic.fb.js
Since we only fork the entrypoint, the `/testing` entrypoint needs to
be forked too to re-export the same things plus `act`. This is a bit
unfortunate. If it becomes a pattern we can consider forking in the
module resolution deeply.
fix flow
* Fix ReactDOM Flow Types
Now that ReactDOM is Flow type checked we need to fix up its types.
* Configure jest to use stable entry for ReactDOM in non-experimental
* Remove additional FeatureFlags that are no longer needed
These are only flagging the exports and no implementation details so we
can control them fully through the export overrides.
* import * as React from "react";
This is the correct way to import React from an ES module since the ES
module will not have a default export. Only named exports.
* import * as ReactDOM from "react-dom"
The changes to the test code relate to changes in JSDOM that come with Jest 25:
* Several JSDOM workarounds are no longer needed.
* Several tests made assertions to match incorrect JSDOM behavior (e.g. setAttribute calls) that JSDOM has now patched to match browsers.
* https://codesandbox.io/s/resets-value-of-datetime-input-to-fix-bugs-in-ios-safari-1ppwh
* JSDOM no longer triggers default actions when dispatching click events.
* https://codesandbox.io/s/beautiful-cdn-ugn8f
* JSDOM fixed (jsdom/jsdom#2700) a bug so that calling focus() on an already focused element does not dispatch a FocusEvent.
* JSDOM now supports passive events.
* JSDOM has improved support for custom CSS properties.
* But requires jsdom/cssstyle#112 to land to support webkit prefixed properties.
* Update Flow to 0.84
* Fix violations
* Use inexact object syntax in files from fbsource
* Fix warning extraction to use a modern parser
* Codemod inexact objects to new syntax
* Tighten types that can be exact
* Revert unintentional formatting changes from codemod
Moves the unit testing library for events into the `packages` directory so it can more easily be used in tests for other react packages, and mirrored internally to help with testing of event hooks we prototype in www.
Introduces a state machine around pointer events to produce more accurate mock
touch events. This allows multi-touch unit tests to be written entirely in
terms of mock pointer interactions, while producing the expected
'changedTouches', 'targetTouches', and 'touches' fields for mock touch events.
* Replace all warning/lowPriWarning with console calls
* Replace console.warn/error with a custom wrapper at build time
* Fail the build for console.error/warn() where we can't read the stack
* prep for codemod
* prep warnings
* rename lint rules
* codemod for ifs
* shim www functions
* Handle more cases in the transform
* Thanks De Morgan
* Run the codemod
* Delete the transform
* Fix up confusing conditions manually
* Fix up www shims to match expected API
* Also check for low-pri warning in the lint rule
Tools like BetterTouchTool for macOS trigger middle-clicks with a 'buttons'
value that doesn't correspond to the middle-mouse button. To account for this
we also inspect the value of 'button'.
Close#17367
`it.experimental` marks that a test only works in Experimental builds.
It also asserts that a test does *not* work in the stable builds. The
main benefit is that we're less likely to accidentally expose an
experimental API before we intend. It also forces us to un- mark an
experimental test once it become stable.
* Tests run in experimental mode by default
For local development, you usually want experiments enabled. Unless
the release channel is set with an environment variable, tests will
run with __EXPERIMENTAL__ set to `true`.
* Remove concurrent APIs from stable builds
Those who want to try concurrent mode should use the experimental
builds instead.
I've left the `unstable_` prefixed APIs in the Facebook build so we
can continue experimenting with them internally without blessing them
for widespread use.
* Turn on SSR flags in experimental build
* Remove prefixed concurrent APIs from www build
Instead we'll use the experimental builds when syncing to www.
* Remove "canary" from internal React version string
