* Remove e.suppressReactErrorLogging check before last resort throw
It's unnecessary here. It was here because this method called console.error().
But we now rethrow with a clean stack, and that's worth doing regardless of whether the logging is silenced.
* Don't print error addendum if 'error' event got preventDefault()
* Add fixtures
* Use an expando property instead of a WeakSet
* Make it a bit less fragile
* Clarify comments
* Add stack unwinding phase for handling errors
A rewrite of error handling, with semantics that more closely match
stack unwinding.
Errors that are thrown during the render phase unwind to the nearest
error boundary, like before. But rather than synchronously unmount the
children before retrying, we restart the failed subtree within the same
render phase. The failed children are still unmounted (as if all their
keys changed) but without an extra commit.
Commit phase errors are different. They work by scheduling an error on
the update queue of the error boundary. When we enter the render phase,
the error is popped off the queue. The rest of the algorithm is
the same.
This approach is designed to work for throwing non-errors, too, though
that feature is not implemented yet.
* Add experimental getDerivedStateFromCatch lifecycle
Fires during the render phase, so you can recover from an error within the same
pass. This aligns error boundaries more closely with try-catch semantics.
Let's keep this behind a feature flag until a future release. For now, the
recommendation is to keep using componentDidCatch. Eventually, the advice will
be to use getDerivedStateFromCatch for handling errors and componentDidCatch
only for logging.
* Reconcile twice to remount failed children, instead of using a boolean
* Handle effect immediately after its thrown
This way we don't have to store the thrown values on the effect list.
* ReactFiberIncompleteWork -> ReactFiberUnwindWork
* Remove startTime
* Remove TypeOfException
We don't need it yet. We'll reconsider once we add another exception type.
* Move replay to outer catch block
This moves it out of the hot path.
* Remove global mocks
They are making it harder to test compiled bundles.
One of them (FeatureFlags) is not used. It is mocked in some specific test files (and that's fine).
The other (FiberErrorLogger) is mocked to silence its output. I'll look if there's some other way to achieve this.
* Add error.suppressReactErrorLogging and use it in tests
This adds an escape hatch to *not* log errors that go through React to the console.
We will enable it for our own tests.
* Update transforms to handle ES modules
* Update Jest to handle ES modules
* Convert react package to ES modules
* Convert react-art package to ES Modules
* Convert react-call-return package to ES Modules
* Convert react-test-renderer package to ES Modules
* Convert react-cs-renderer package to ES Modules
* Convert react-rt-renderer package to ES Modules
* Convert react-noop-renderer package to ES Modules
* Convert react-dom/server to ES modules
* Convert react-dom/{client,events,test-utils} to ES modules
* Convert react-dom/shared to ES modules
* Convert react-native-renderer to ES modules
* Convert react-reconciler to ES modules
* Convert events to ES modules
* Convert shared to ES modules
* Remove CommonJS support from transforms
* Move ReactDOMFB entry point code into react-dom/src
This is clearer because we can use ES imports in it.
* Fix Rollup shim configuration to work with ESM
* Fix incorrect comment
* Exclude external imports without side effects
* Fix ReactDOM FB build
* Remove TODOs I don’t intend to fix yet
* Use relative paths in packages/react
* Use relative paths in packages/react-art
* Use relative paths in packages/react-cs
* Use relative paths in other packages
* Fix as many issues as I can
This uncovered an interesting problem where ./b from package/src/a would resolve to a different instantiation of package/src/b in Jest.
Either this is a showstopper or we can solve it by completely fobbidding remaining /src/.
* Fix all tests
It seems we can't use relative requires in tests anymore. Otherwise Jest becomes confused between real file and symlink.
https://github.com/facebook/jest/issues/3830
This seems bad... Except that we already *don't* want people to create tests that import individual source files.
All existing cases of us doing so are actually TODOs waiting to be fixed.
So perhaps this requirement isn't too bad because it makes bad code looks bad.
Of course, if we go with this, we'll have to lint against relative requires in tests.
It also makes moving things more painful.
* Prettier
* Remove @providesModule
* Fix remaining Haste imports I missed earlier
* Fix up paths to reflect new flat structure
* Fix Flow
* Fix CJS and UMD builds
* Fix FB bundles
* Fix RN bundles
* Prettier
* Fix lint
* Fix warning printing and error codes
* Fix buggy return
* Fix lint and Flow
* Use Yarn on CI
* Unbreak Jest
* Fix lint
* Fix aliased originals getting included in DEV
Shouldn't affect correctness (they were ignored) but fixes DEV size regression.
* Record sizes
* Fix weird version in package.json
* Tweak bundle labels
* Get rid of output option by introducing react-dom/server.node
* Reconciler should depend on prop-types
* Update sizes last time
* Enable Yarn workspaces for packages/*
* Move src/isomorphic/* into packages/react/src/*
* Create index.js stubs for all packages in packages/*
This makes the test pass again, but breaks the build because npm/ folders aren't used yet.
I'm not sure if we'll keep this structure--I'll just keep working and fix the build after it settles down.
* Put FB entry point for react-dom into packages/*
* Move src/renderers/testing/* into packages/react-test-renderer/src/*
Note that this is currently broken because Jest ignores node_modules,
and so Yarn linking makes Jest skip React source when transforming.
* Remove src/node_modules
It is now unnecessary. Some tests fail though.
* Add a hacky workaround for Jest/Workspaces issue
Jest sees node_modules and thinks it's third party code.
This is a hacky way to teach Jest to still transform anything in node_modules/react*
if it resolves outside of node_modules (such as to our packages/*) folder.
I'm not very happy with this and we should revisit.
* Add a fake react-native package
* Move src/renderers/art/* into packages/react-art/src/*
* Move src/renderers/noop/* into packages/react-noop-renderer/src/*
* Move src/renderers/dom/* into packages/react-dom/src/*
* Move src/renderers/shared/fiber/* into packages/react-reconciler/src/*
* Move DOM/reconciler tests I previously forgot to move
* Move src/renderers/native-*/* into packages/react-native-*/src/*
* Move shared code into packages/shared
It's not super clear how to organize this properly yet.
* Add back files that somehow got lost
* Fix the build
* Prettier
* Add missing license headers
* Fix an issue that caused mocks to get included into build
* Update other references to src/
* Re-run Prettier
* Fix lint
* Fix weird Flow violation
I didn't change this file but Flow started complaining.
Caleb said this annotation was unnecessarily using $Abstract though so I removed it.
* Update sizes
* Fix stats script
* Fix packaging fixtures
Use file: instead of NODE_PATH since NODE_PATH.
NODE_PATH trick only worked because we had no react/react-dom in root node_modules, but now we do.
file: dependency only works as I expect in Yarn, so I moved the packaging fixtures to use Yarn and committed lockfiles.
Verified that the page shows up.
* Fix art fixture
* Fix reconciler fixture
* Fix SSR fixture
* Rename native packages
