* Use consistent naming for unstable_testing entry point
* Exclude the testing build from non-experimental builds except at FB
* FB builds shouldn't contribute to whether we include the npm files
* Exclude exports fields if we delete the files entry
* Move test to no longer be internal so we can test against the build
* Update the bundle artifact names since they've now changed
* Gate import since it doesn't exist
* Use the server src files as entry points for the builds/tests
We need one top level entry point to target two builds so we can't have
the top level one be the entry point for the builds.
* Same thing but with the modern entry point
* Clean up partial renderer entry points
I made a mistake by leaving server.browser.stable in which is the partial
renderer for the browser build of stable. That should use the legacy fizz
one.
Since the only usage of the partial renderer now is at FB and we don't use
it with Node, I removed the Node build of partial renderer too.
* Remove GC test
No code is running this path anymore. Ideally this should be ported to
a Fizz form.
* Wire up DOM legacy build
* Hack to filter extra comments for testing purposes
* Use string concat in renderToString
I think this might be faster. We could probably use a combination of this
technique in the stream too to lower the overhead.
* Error if we can't complete the root synchronously
Maybe this should always error but in the async forms we can just delay
the stream until it resolves so it does have some useful semantics.
In the synchronous form it's never useful though. I'm mostly adding the
error because we're testing this behavior for renderToString specifically.
* Gate memory leak tests of internals
These tests don't translate as is to the new implementation and have been
ported to the Fizz tests separately.
* Enable Fizz legacy mode in stable
* Add wrapper around the ServerFormatConfig for legacy mode
This ensures that we can inject custom overrides without negatively
affecting the new implementation.
This adds another field for static mark up for example.
* Wrap pushTextInstance to avoid emitting comments for text in static markup
* Don't emit static mark up for completed suspense boundaries
Completed and client rendered boundaries are only marked for the client
to take over.
Pending boundaries are still supported in case you stream non-hydratable
mark up.
* Wire up generateStaticMarkup to static API entry points
* Mark as renderer for stable
This shouldn't affect the FB one ideally but it's done with the same build
so let's hope this works.
Some legacy environments can not encode non-strings. Those would specify
both as strings. They'll throw for binary data.
Some environments have to encode strings (like web streams). Those would
encode both as uint8array.
Some environments (like Node) can do either. It can be beneficial to leave
things as strings in case the native stream can do something smart with it.
* Move files
* Update paths
* Rename import variables
* Rename /server to /writer
This is mainly because "React Server Server" is weird so we need another
dimension.
* Use "react-server" convention to enforce that writer is only loaded in a server
This adds a new dimension similar to dom-relay. It's different from
"native" which would be Flight for RN without Relay.
This has some copy-pasta that's the same between the two Relay builds but
the key difference will be Metro and we're not quite sure what other
differences there will be yet.
* Remove Blocks
* Remove Flight Server Runtime
There's no need for this now that the JSResource is part of the bundler
protocol. Might need something for Webpack plugin specifically later.
* Devtools
* 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.
* 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
* 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
