This doesn't rely on checking the tag. When the alternate of a parent
is missing, it assumes it's a fragment indirection and moves onto the
next parent fiber.
Whenever we do this, Rollup needs to materialize this as an object.
This causes it to also add the Babel compatibility property which is
unnecessary bloat. However, since when we use these, we leak the object
this often also deopts any compiler optimizations.
If we really need an object we should export default an object.
Currently there is an exception for DOMTopLevelEventTypes since
listing out the imports is a PITA and it doesn't escape so it should
get properly inlined. We should probably move to a different pattern
to avoid this for consistency though.
* Simplify imports in ReactChildFiber
* Import type first in ReactCurrentFiber
* Simplify imports in ReactFiberBeginWork
* Simplify imports in ReactFiberScheduler
* Simplify import in ReactFiberTreeReflection
* Simplify import in ReactFiberUnwindWork
* Remove repeated import
* Fix imports from ReactFiberExpirationTime
* Master imports in ReactFiberBeginWork
* Introduce elementType field
This will be used to store the wrapped type of an element. E.g. pure and
lazy.
The existing type field will be used for the unwrapped type within them.
* Store the unwrapped type on the type field of lazy components
* Use the raw tags for lazy components
Instead, we check if the elementType and type are equal to test if
we need to resolve props. This is slightly slower in the normal case
but will yield less code and branching.
* Clean up lazy branches
* Collapse work tag numbering
* Split IndeterminateComponent out from Lazy
This way we don't have to check the type in a hacky way in the
indeterminate path. Also, lets us deal with lazy that resolves to
indeterminate and such.
* Missing clean up in rebase
* Accept promise as element type
On the initial render, the element will suspend as if a promise were
thrown from inside the body of the unresolved component. Siblings should
continue rendering and if the parent is a Placeholder, the promise
should be captured by that Placeholder.
When the promise resolves, rendering resumes. If the resolved value
has a `default` property, it is assumed to be the default export of
an ES module, and we use that as the component type. If it does not have
a `default` property, we use the resolved value itself.
The resolved value is stored as an expando on the promise/thenable.
* Use special types of work for lazy components
Because reconciliation is a hot path, this adds ClassComponentLazy,
FunctionalComponentLazy, and ForwardRefLazy as special types of work.
The other types are not supported, but wouldn't be placed into a
separate module regardless.
* Resolve defaultProps for lazy types
* Remove some calls to isContextProvider
isContextProvider checks the fiber tag, but it's typically called after
we've already refined the type of work. We should get rid of it. I
removed some of them in the previous commit, and deleted a few more
in this one. I left a few behind because the remaining ones would
require additional refactoring that feels outside the scope of this PR.
* Remove getLazyComponentTypeIfResolved
* Return baseProps instead of null
The caller compares the result to baseProps to see if anything changed.
* Avoid redundant checks by inlining getFiberTagFromObjectType
* Move tag resolution to ReactFiber module
* Pass next props to update* functions
We should do this with all types of work in the future.
* Refine component type before pushing/popping context
Removes unnecessary checks.
* Replace all occurrences of _reactResult with helper
* Move shared thenable logic to `shared` package
* Check type of wrapper object before resolving to `default` export
* Return resolved tag instead of reassigning
* Use %s in the console calls
* Add shared/warningWithStack
* Convert some warning callsites to warningWithStack
* Use warningInStack in shared utilities and remove unnecessary checks
* Replace more warning() calls with warningWithStack()
* Fixes after rebase + use warningWithStack in react
* Make warning have stack by default; warningWithoutStack opts out
* Forbid builds that may not use internals
* Revert newly added stacks
I changed my mind and want to keep this PR without functional changes. So we won't "fix" any warnings that are already missing stacks. We'll do it in follow-ups instead.
* Fix silly find/replace mistake
* Reorder imports
* Add protection against warning argument count mismatches
* Address review
* Fix getComponentName() for types with nested $$typeof
* Temporarily remove Profiler ID from messages
* Change getComponentName() signature to take just type
It doesn't actually need the whole Fiber.
* Remove getComponentName() forks in isomorphic and SSR
* Remove unnecessary .type access where we already have a type
* Remove unused type
* Move ReactFiberTreeReflection to react-reconciler/reflection #11659
* Use * for react-reconciler
We don't know the latest local version, and release script currently doesn't bump deps automatically.
* Remove unused field
* Use CommonJS in entry point for consistency
* Undo the CommonJS change
I didn't realize it would break the build.
* Record sizes
* Remove reconciler fixtures
They're unnecessary now that we run real tests on reconciler bundles.
* Only renderers should depend on reconciler code
* Remove react-art dependency on react-dom modules
They share ReactDOMFrameScheduling so I moved it to shared.
* 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
