The old version of prettier we were using didn't support the Flow syntax
to access properties in a type using `SomeType['prop']`. This updates
`prettier` and `rollup-plugin-prettier` to the latest versions.
I added the prettier config `arrowParens: "avoid"` to reduce the diff
size as the default has changed in Prettier 2.0. The largest amount of
changes comes from function expressions now having a space. This doesn't
have an option to preserve the old behavior, so we have to update this.
These suppressions are no longer required.
Generated using:
```sh
flow/tool update-suppressions .
```
followed by adding back 1 or 2 suppressions that were only triggered in
some configurations.
This setting is an incremental path to the next Flow version enforcing
type annotations on most functions (except some inline callbacks).
Used
```
node_modules/.bin/flow codemod annotate-functions-and-classes --write .
```
to add a majority of the types with some hand cleanup when for large
inferred objects that should just be `Fiber` or weird constructs
including `any`.
Suppressed the remaining issues.
Builds on #25918
We have a currently unreproducible flaky e2e test. This PR captures snapshots on e2e test failures so we can better debug flaky e2e tests that don't fail locally.
This PR:
* Increases test retry count to 2 so that flaky tests have more of a chance to pass
* Ideally most e2e tests will run for all React versions (and ensure DevTools elegantly fails if React doesn't support its features). However, some features aren't supported in older React versions at all (ex. Profiling) Add runOnlyForReactRange function in these cases to skip tests that don't satisfy the correct React semver range
* Fix should allow searching for component by name test, which was flaky because sometimes the Searchbox would be unfocused the second time we try to type in it
* Edited test Should allow elements to be inspected to check that element inspect gracefully fails in older React versions
* Updated config to add a config.use.url field and a config.use.react_version field, which change depending on the React Version (and whether it's specified)
* Move createRoot/hydrateRoot to /client
We want these APIs ideally to be imported separately from things you
might use in arbitrary components (like flushSync). Those other methods
are "isomorphic" to how the ReactDOM tree is rendered. Similar to hooks.
E.g. importing flushSync into a component that only uses it on the client
should ideally not also pull in the entry client implementation on the
server.
This also creates a nicer parity with /server where the roots are in a
separate entry point.
Unfortunately, I can't quite do this yet because we have some legacy APIs
that we plan on removing (like findDOMNode) and we also haven't implemented
flushSync using a flag like startTransition does yet.
Another problem is that we currently encourage these APIs to be aliased by
/profiling (or unstable_testing). In the future you don't have to alias
them because you can just change your roots to just import those APIs and
they'll still work with the isomorphic forms. Although we might also just
use export conditions for them.
For that all to work, I went with a different strategy for now where the
real API is in / but it comes with a warning if you use it. If you instead
import /client it disables the warning in a wrapper. That means that if you
alias / then import /client that will inturn import the alias and it'll
just work.
In a future breaking changes (likely when we switch to ESM) we can just
remove createRoot/hydrateRoot from / and move away from the aliasing
strategy.
* Update tests to import from react-dom/client
* Fix fixtures
* Update warnings
* Add test for the warning
* Update devtools
* Change order of react-dom, react-dom/client alias
I think the order matters here. The first one takes precedence.
* Require react-dom through client so it can be aliased

* Add .browser and .node explicit entry points
This can be useful when the automatic selection doesn't work properly.
* Remove react/index
I'm not sure why I added this in the first place. Perhaps due to how our
builds work somehow.
* Remove build-info.json from files field
Builds on top of the existing Playwright tests to plug in the test selector API: https://gist.github.com/bvaughn/d3c8b8842faf2ac2439bb11773a19cec
My goals in doing this are to...
1. Experiment with the new API to see what works and what doesn't.
2. Add some test selector attributes (and remove DOM-structure based selectors).
3. Focus the tests on DevTools itself (rather than the test app).
I also took this opportunity to add a few new test cases– like named hooks, editable props, component search, and profiling- just to play around more with the Playwright API.
Relates to issue #22646
This is being done so that we can embed DevTools within the new React (beta) docs.
The primary changes here are to `react-devtools-inline/backend`:
* Add a new `createBridge` API
* Add an option to the `activate` method to support passing in the custom bridge object.
The `react-devtools-inline` README has been updated to include these new methods.
To verify these changes, this commit also updates the test shell to add a new entry-point for multiple DevTools.
This commit also replaces two direct calls to `window.postMessage()` with `bridge.send()` (and adds the related Flow types).
This change adds a new "react-dom/unstable_testing" entry point but I believe its contents will exactly match "react-dom/index" for the stable build. (The experimental build will have the added new selector APIs.)
