* First pass at scaffolding out the Node implementation of react-data.
While incomplete, this patch contains some changes to the react-data
package in order to start adding support for Node.
The first part of this change accounts for splitting react-data/fetch
into two discrete entries, adding (and defaulting to) the Node
implementation.
The second part is sketching out a rough approximation of `fetch` for
Node. This implementation is not complete by any means, but provides a
starting point.
* Remove NodeFetch module and put it directly into ReactDataFetchNode.
* Replaced react-data with react-fetch.
This patch shuffles around some of the scaffolding that was in
react-data in favor of react-fetch. It also removes the additional
"fetch" package in favor of something flatter.
* Tweak package organization
* Simplify and add a test

* Add a way to load nested entrypoint
* Only expose URL params to nested routers
* Add keys to route definitions
* [Blocks Fixture] Drop the Blocks
We've been shipping unprefixed experimental APIs (like `createRoot` and
`useTransition`) to the Experimental release channel, with the rationale
that because these APIs do not appear in any stable release, we're free
to change or remove them later without breaking any downstream projects.
What we didn't consider is that downstream projects might be tempted to
use feature detection:
```js
const useTransition = React.useTransition || fallbackUseTransition;
```
This pattern assumes that the version of `useTransition` that exists in
the Experimental channel today has the same API contract as the final
`useTransition` API that we'll eventually ship to stable.
To discourage feature detection, I've added an `unstable_` prefix to
all of our unstable APIs.
The Facebook builds still have the unprefixed APIs, though. We will
continue to support those; if we make any breaking changes, we'll
migrate the internal callers like we usually do. To make testing easier,
I added the `unstable_`-prefixed APIs to the www builds, too. That way
our tests can always use the prefixed ones without gating on the
release channel.
* 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
* [Blocks] Use native fetch
* Use the prototype
* Support arrayBuffer() and blob()
* ctor
* Simplify
* Use an expando
* Keep a map of formats
* Unused
* Remove unnecessary second property read
* Keep it simple
* Store the original thenable
* Rename ReactCache -> ReactCacheOld
We still use it in some tests so I'm going to leave it for now. I'll start making the new one in parallel in the react package.
* Add react/unstable-cache entry point
* Add react-data entry point
* Initial implementation of cache and data/fetch
* Address review
* Add more edge cases to fixture
Also adjust some expectations. I think the column should ideally be 1 but varies.
The Example row is one line off because it throws on the hook but should ideally be the component.
Similarly class components with constructors may have the line in the constructor.
* Account for the construct call taking a stack frame
We do this by first searching for the first different frame, then find
the same frames and then find the first different frame again.
* Throw controls
Otherwise they don't get a stack frame associated with them in IE.
* Protect against generating stacks failing
Errors while generating stacks will bubble to the root. Since this technique
is a bit sketchy, we should probably protect against it.
* Don't construct the thing that throws
Instead, we pass the prototype as the "this". It's new every time anyway.
* Implement component stack extraction hack
* Normalize errors in tests
This drops the requirement to include owner to pass the test.
* Special case tests
* Add destructuring to force toObject which throws before the side-effects
This ensures that we don't double call yieldValue or advanceTime in tests.
Ideally we could use empty destructuring but ES lint doesn't like it.
* Cache the result in DEV
In DEV it's somewhat likely that we'll see many logs that add component
stacks. This could be slow so we cache the results of previous components.
* Fixture
* Add Reflect to lint
* Log if out of range.
* Fix special case when the function call throws in V8
In V8 we need to ignore the first line. Normally we would never get there
because the stacks would differ before that, but the stacks are the same if
we end up throwing at the same place as the control.
* Eject CRA from Flight
We need to eject because we're going to add a custom Webpack Plugin.
We can undo this once the plugin has upstreamed into CRA.
* Add Webpack plugin build
I call this entry point "webpack-plugin" instead of "plugin" even though
this is a webpack specific package. That's because there will also be a
Node.js plugin to do the server transform.
* Add Flight Webpack plugin to fixture
* Rm UMD builds
* Transform classes
* Rename webpack-plugin to plugin
This avoids the double webpack name. We're going to reuse this for both
server and client.
* Remove /dist/ UMD builds
We publish UMDs to npm (and we're considering stopping even that).
This means we'll stop publishing to http://react.zpao.com/builds/master/latest/

* add email input fixture to show cursor jump

Originally the idea was to hide all suspending behind getters or proxies.
However, this has some issues with perf on hot code like React elements.
It also makes it too easy to accidentally access it the first time in an
effect or callback where things aren't allowed to suspend. Making it
an explicit method call avoids this issue.
All other suspending has moved to explicit lazy blocks (and soon elements).
The only thing remaining is the root. We could require the root to be an
element or block but that creates an unfortunate indirection unnecessarily.
Instead, I expose a readRoot method on the response. Typically we try to
avoid virtual dispatch but in this case, it's meant that you build
abstractions on top of a Flight response so passing it a round is useful.
This reverts commit cf0081263c.
The changes to the test code relate to changes in JSDOM that come with Jest 25:
* Several JSDOM workarounds are no longer needed.
* Several tests made assertions to match incorrect JSDOM behavior (e.g. setAttribute calls) that JSDOM has now patched to match browsers.
* https://codesandbox.io/s/resets-value-of-datetime-input-to-fix-bugs-in-ios-safari-1ppwh
* JSDOM no longer triggers default actions when dispatching click events.
* https://codesandbox.io/s/beautiful-cdn-ugn8f
* JSDOM fixed (jsdom/jsdom#2700) a bug so that calling focus() on an already focused element does not dispatch a FocusEvent.
* JSDOM now supports passive events.
* JSDOM has improved support for custom CSS properties.
* But requires jsdom/cssstyle#112 to land to support webkit prefixed properties.
This replaces the HTML renderer with instead resolving host elements into
arrays tagged with the react.element symbol. These turn into proper
React Elements on the client.
The symbol is encoded as the magical value "$". This has security implications
so this special value needs to remain escaped for other strings.
We could just encode the element as {$$typeof: "$", key: key props: props}
but that's a lot more bytes. So instead I encode it as:
["$", key, props] and then convert it back.
It would be nicer if React's reconciler could just accept these tuples.
The testing build versions of react-dom are included in the builds right now, but we're not ready to share them yet. This PR removes them for now (back soon for the next release)
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
