* Split out into helper functions
This is similar to the structure of beginWork in Fiber.
* Split the rendering of a node from recursively rendering a node
This lets us reuse render node at the root which doesn't spawn new work.
* Remove redundant initial of isArray (#21163)
* Reapply prettier
* Type the isArray function with refinement support
This ensures that an argument gets refined just like it does if isArray is
used directly.
I'm not sure how to express with just a direct reference so I added a
function wrapper and confirmed that this does get inlined properly by
closure compiler.
* A few more
* Rename unit test to internal
This is not testing a bundle.

* Implement DOM format config structure
* Styles
* Input warnings
* Textarea special cases
* Select special cases
* Option special cases
We read the currently selected value from the FormatContext.
* Warning for non-lower case HTML
We don't change to lower case at runtime anymore but keep the warning.
* Pre tags innerHTML needs to be prefixed
This is because if you do the equivalent on the client using innerHTML,
this is the effect you'd get.
* Extract errors
* Encode tables as a special insertion mode
The table modes are special in that its children can't be created outside
a table context so we need the segment container to be wrapped in a table.
* Move formatContext from Task to Segment
It works the same otherwise. It's just that this context needs to outlive
the task so that I can use it when writing the segment.
* Use template tag for placeholders and inserted dummy nodes with IDs
These can be used in any parent. At least outside IE11. Not sure yet what
happens in IE11 to these.
Not sure if these are bad for perf since they're special nodes.
* Add special wrappers around inserted segments depending on their insertion mode
* Allow the root namespace to be configured
This allows us to insert the correct wrappers when streaming into an
existing non-HTML tree.
* Add comment
* Add format context
* Let the Work node hold all working state for the recursive loop
Stacks are nice and all but there's a cost to maintaining each frame
both in terms of stack size usage and writing to it.
* Move current format context into work
* Synchronously render children of a Suspense boundary
We don't have to spawn work and snapshot the context. Instead we can try
to render the boundary immediately in case it works.
* Lazily create the fallback work
Instead of eagerly create the fallback work and then immediately abort it.
We can just avoid creating it if we finish synchronously.
* Report errors to a global handler
This allows you to log errors or set things like status codes.
* Add complete callback
* onReadyToStream callback
This is typically not needed because if you want to stream when the
root is ready you can just start writing immediately.
* Rename onComplete -> onCompleteAll
* Use identifierPrefix to avoid conflicts within the same response
identifierPrefix as an option exists to avoid useOpaqueIdentifier conflicting
when different renders are used within one HTML response.
This lets this be configured for the DOM renderer specifically since it's DOM
specific whether they will conflict across trees or not.
* Add test for using multiple containers in one HTML document
* Track all suspended work while it's still pending
This allows us to abort work and put everything into client rendered mode
if we don't want to wait for further I/O.
It also allows us to cancel fallbacks if we complete the main content
before the fallback.
* Expose abort API to the browser streams
Since this API already returns a value, we need to use destructuring to
expose more options.
* Add a test including the client actually client rendering it
* Use AbortSignal option for W3C streams instead of external control
* Clean up listener after it's used once
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.
* Destroy the stream with an error if the root throws
But not if the error happens inside a suspense boundary.
* Try rewriting the test to see if it works in other Node envs
* Copy some infra structure patterns from Flight
* Basic data structures
* Move structural nodes and instruction commands to host config
* Move instruction command to host config
In the DOM this is implemented as script tags. The first time it's emitted
it includes the function. Future calls invoke the same function.
The side of the complete boundary function in particular is unfortunately
large.
* Implement Fizz Noop host configs
This is implemented not as a serialized protocol but by-passing the
serialization when possible and instead it's like a live tree being
built.
* Implement React Native host config
This is not wired up. I just need something for the flow types since
Flight and Fizz are both handled by the isServerSupported flag.
Might as well add something though.
The principle of this format is the same structure as for HTML but a
simpler binary format.
Each entry is a tag followed by some data and terminated by null.
* Check in error codes
* Comment
* Enable prefer-const rule
Stylistically I don't like this but Closure Compiler takes advantage of
this information.
* Auto-fix lints
* Manually fix the remaining callsites
* 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.
