* Rename Flight to Transport
Flight is still the codename for the implementation details (like Fiber).
However, now the public package is react-transport-... which is only
intended to be used directly by integrators.
* Rename names
* Lazily initialize models as they're read intead of eagerly when received
This ensures that we don't spend CPU cycles processing models that we're
not going to end up rendering.
This model will also allow us to suspend during this initialization if
data is not yet available to satisfy the model.
* Refactoring carefully to ensure bundles still compile to something optimal
* Remove generic from Response
The root model needs to be cast at one point or another same as othe
chunks. So we can parameterize the read instead of the whole Response.
* Read roots from the 0 key of the map
The special case to read the root isn't worth the field and code.
* Store response on each Chunk
Instead of storing it on the data tuple which is kind of dynamic, we store
it on each Chunk. This uses more memory. Especially compared to just making
initializeBlock a closure, but overall is simpler.
* Rename private fields to underscores
Response objects are exposed.
* Encode server components as delayed references
This allows us to stream in server components one after another over the
wire. It also allows parallelizing their fetches and resuming only the
server component instead of the whole parent block.
This doesn't yet allow us to suspend deeper while waiting on this content
because we don't have "lazy elements".
This is equivalent to the jsx-runtime in that this is what the compiled
output on the server is supposed to target.
It's really just the same code for all the different Flights, but they
have different types in their arguments so each one gets their own entry
point. We might use this to add runtime warnings per entry point.
Unlike the client-side React.block call this doesn't provide the factory
function that curries the load function. The compiler is expected to wrap
this call in the currying factory.
* 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.
* Rename to clarify that it's client-only
* Rename FizzStreamer to FizzServer for consistency
* Rename react-flight to react-client/flight
For consistency with react-server. Currently this just includes flight
but it could be expanded to include the whole reconciler.
* Add Relay Flight Build
* Rename ReactServerHostConfig to ReactServerStreamConfig
This will be the config specifically for streaming purposes.
There will be other configs for other purposes.
* Require deep for reconcilers
* Delete inline* files
* Delete react-reconciler/persistent
This no longer makes any sense because it react-reconciler takes
supportsMutation or supportsPersistence as options. It's no longer based
on feature flags.
* Fix jest mocking
* Fix Flow strategy
We now explicitly list which paths we want to be checked by a renderer.
For every other renderer config we ignore those paths.
Nothing is "any" typed. So if some transitive dependency isn't reachable
it won't be accidentally "any" that leaks.
This PR introduces adds `react/testing` and `react-dom/testing`.
- changes infra to generate these builds
- exports act on ReactDOM in these testing builds
- uses the new test builds in fixtures/dom
In the next PR -
- I'll use the new builds for all our own tests
- I'll replace usages of TestUtils.act with ReactDOM.act.
* 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
* Move Flight DOM to Webpack Specific Packagee
We'll have Webpack specific coupling so we need to ensure that it can be
versioned separately from various Webpack versions. We'll also have builds
for other bundlers in the future.
* Move to peerDep
* Move DOM Flight Tests
* Merge ReactFlightIntegration into ReactFlightDOM
This was an integration test. We can add to it.
* Fix fixture paths
* Add Flight Build and Unify HostFormat Config between Flight and Fizz
* Add basic resolution of models
* Add basic Flight fixture
Demonstrates the streaming protocol.
* Rename to flight-server to distinguish from the client parts
* Add Flight Client package and entry point
* Fix fixture
This implements 'usePress' in user-space as a combination of 'useKeyboard' and 'useTap'. The existing 'usePress' API is preserved for now. The previous 'usePress' implementation is moved to 'PressLegacy'.
* Rewrite ReactFiberScheduler
Adds a new implementation of ReactFiberScheduler behind a feature flag.
We will maintain both implementations in parallel until the new one
is proven stable enough to replace the old one.
The main difference between the implementations is that the new one is
integrated with the Scheduler package's priority levels.
* Conditionally add fields to FiberRoot
Some fields only used by the old scheduler, and some by the new.
* Add separate build that enables new scheduler
* Re-enable skipped test
If synchronous updates are scheduled by a passive effect, that work
should be flushed synchronously, even if flushPassiveEffects is
called inside batchedUpdates.
* Passive effects have same priority as render
* Revert ability to cancel the current callback
React doesn't need this anyway because it never schedules callbacks if
it's already rendering.
* Revert change to FiberDebugPerf
Turns out this isn't neccessary.
* Fix ReactFiberScheduler dead code elimination
Should initialize to nothing, then assign the exports conditionally,
instead of initializing to the old exports and then reassigning to the
new ones.
* Don't yield before commit during sync error retry
* Call Scheduler.flushAll unconditionally in tests
Instead of wrapping in enableNewScheduler flag.
* [Fizz] Add Flow/Jest/Rollup build infra
Add a new package for react-stream which allows for custom server renderer
outputs. I picked the name because it's a reasonable name but also
because the npm name is currently owned by a friend of the project.
The react-dom build has its own inlined server renderer under the
name `react-dom/fizz`.
There is also a noop renderer to be used for testing. At some point
we might add a public one to test-renderer but for now I don't want to have
to think about public API design for the tests.
* Add FormatConfig too
We need to separate the format (DOM, React Native, etc) from the host
running the server (Node, Browser, etc).
* Basic wiring between Node, Noop and DOM configs
The Node DOM API is pipeToNodeStream which accepts a writable stream.
* Merge host and format config in dynamic react-stream entry point
Simpler API this way but also avoids having to fork the wrapper config.
Fixes noop builds.
* Add setImmediate/Buffer globals to lint config
Used by the server renderer
* Properly include fizz.node.js
Also use forwarding to it from fizz.js in builds so that tests covers
this.
* Make react-stream private since we're not ready to publish
or even name it yet
* Rename Renderer -> Streamer
* Prefix react-dom/fizz with react-dom/unstable-fizz
* Add Fizz Browser host config
This lets Fizz render to WHATWG streams. E.g. for rendering in a
Service Worker.
I added react-dom/unstable-fizz.browser as the entry point for this.
Since we now have two configurations of DOM. I had to add another
inlinedHostConfigs configuration called `dom-browser`. The reconciler
treats this configuration the same as `dom`. For stream it checks
against the ReactFizzHostConfigBrowser instead of the Node one.
* Add Fizz Browser Fixture
This is for testing server rendering - on the client.
* Lower version number to detach it from react-reconciler version
* Extract base Jest config
This makes it easier to change the source config without affecting the build test config.
* Statically import the host config
This changes react-reconciler to import HostConfig instead of getting it through a function argument.
Rather than start with packages like ReactDOM that want to inline it, I started with React Noop and ensured that *custom* renderers using react-reconciler package still work. To do this, I'm making HostConfig module in the reconciler look at a global variable by default (which, in case of the react-reconciler npm package, ends up being the host config argument in the top-level scope).
This is still very broken.
* Add scaffolding for importing an inlined renderer
* Fix the build
* ES exports for renderer methods
* ES modules for host configs
* Remove closures from the reconciler
* Check each renderer's config with Flow
* Fix uncovered Flow issue
We know nextHydratableInstance doesn't get mutated inside this function, but Flow doesn't so it thinks it may be null.
Help Flow.
* Prettier
* Get rid of enable*Reconciler flags
They are not as useful anymore because for almost all cases (except third party renderers) we *know* whether it supports mutation or persistence.
This refactoring means react-reconciler and react-reconciler/persistent third-party packages now ship the same thing.
Not ideal, but this seems worth how simpler the code becomes. We can later look into addressing it by having a single toggle instead.
* Prettier again
* Fix Flow config creation issue
* Fix imprecise Flow typing
* Revert accidental changes
* use different eslint config for es6 and es5
* remove confusing eslint/baseConfig.js & add more eslint setting for es5, es6
* more clear way to run eslint on es5 & es6 file
* seperate ESNext, ES6, ES6 path, and use different lint config
* rename eslint config file & update eslint rules
* Undo yarn.lock changes
* Rename a file
* Remove unnecessary exceptions
* Refactor a little bit
* Refactor and tweak the logic
* Minor issues
