## Summary
Overlooked when was working on
https://github.com/facebook/react/pull/26887.
- Added `webpack` packages as dev dependencies to `react-devtools-core`,
because it calls webpack to build
- Added `process` package as dev dependency, because it is injected with
`ProvidePlugin` (otherwise fails with Safari usage)
- Updated rule for sourcemaps
- Listed required externals for `standalone` build
Tested on RN application & Safari
## Summary
- Updated `webpack` (and all related packages) to v5 in
`react-devtools-*` packages.
- I haven't touched any `TODO (Webpack 5)`. Tried to poke it, but each
my attempt failed and parsing hook names feature stopped working. I will
work on this in a separate PR.
- This work is one of prerequisites for updating Firefox extension to
manifests v3
related PRs:

## How did you test this change?
Tested on all surfaces, explicitly checked that parsing hook names
feature still works.

Just a small upgrade to keep us current and remove unused suppressions
(probably fixed by some upgrade since).
- `*` is no longer allowed and has been an alias for `any` for a while
now.
## Summary
This pull request aims to improve the maintainability of the codebase by
consolidating types and constants that are shared between the backend
and frontend. This consolidation will allow us to maintain backwards
compatibility in the frontend in the future.
To achieve this, we have moved the shared types and constants to the
following blessed files:
- react-devtools-shared/src/constants
- react-devtools-shared/src/types
- react-devtools-shared/src/backend/types
- react-devtools-shared/src/backend/NativeStyleEditor/types
Please note that the inclusion of NativeStyleEditor in this list is
temporary, and we plan to remove it once we have a better plugin system
in place.
## How did you test this change?
I have tested it by running `yarn flow dom-node`, which reports no
errors.
## Summary
- #26234 is reverted and replaced with a better approach
- introduce a new global devtools variable to decouple the global hook's
dependency on backend/console.js, and add it to react-devtools-inline
and react-devtools-standalone
With this PR, I want to introduce a new principle to hook.js: we should
always be alert when editing this file and avoid importing from other
files.
In the past, we try to inline a lot of the implementation because we use
`.toString()` to inject this function from the extension (we still have
some old comments left). Although it is no longer inlined that way, it
has became now more important to keep it clean as it is a de facto
global API people are using (9.9K files contains it on Github search as
of today).
**File size change for extension:**
Before:
379K installHook.js
After:
21K installHook.js
363K renderer.js

## Summary
<!--
Explain the **motivation** for making this change. What existing problem
does the pull request solve?
-->
This pull request emit the trace update events `drawTraceUpdates` with
the trace frame information when the trace update drawer runs outside of
web environment. This allows React Devtool running in mobile or other
platforms have a chance to render such highlights and provide similar
feature on web to provide re-render highlights. This is a feature needed
for identifying unnecessary re-renders.
## How did you test this change?

I tested this change with Flipper desktop app running against mobile
app, and verified that the event with correct array of frames are
passing through properly.
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
# Summary
* This PR adds support for persisting certain settings to device
storage, allowing e.g. RN apps to properly patch the console when
restarted.
* The device storage APIs have signature `getConsolePatchSettings()` and
`setConsolePatchSettings(string)`, in iOS, are thin wrappers around the
`Library/Settings` turbomodule, and wrap a new TM that uses the `SharedPreferences` class in Android.
* Pass device storage getters/setters from RN to DevTools'
`connectToDevtools`. The setters are then used to populate values on
`window`. Later, the console is patched using these values.
* If we receive a notification from DevTools that the console patching
fields have been updated, we write values back to local storage.
* See https://github.com/facebook/react-native/pull/34903
# How did you test this change?
Manual testing, `yarn run test-build-devtools`, `yarn run prettier`,
`yarn run flow dom`
## Manual testing setup:
### React DevTools Frontend
* Get the DevTools frontend in flipper:
* `nvm install -g react-devtools-core`, then replace that package with a
symlink to the local package
* enable "use globally installed devtools" in flipper
* yarn run start in react-devtools, etc. as well
### React DevTools Backend
* `yarn run build:backend` in react-devtools-core, then copy-paste that
file to the expo app's node_modules directory
### React Native
* A local version of React Native can be patched in by modifying an expo
app's package.json, as in `"react-native":
"rbalicki2/react-native#branch-name"`
# Versioning safety
* There are three versioned modules to worry about: react native, the
devtools frontend and the devtools backend.
* The react devtools backend checks for whether a `cachedSettingsStore`
is passed from react native. If not (e.g. if React Native is outdated),
then no behavior changes.
* The devtools backend reads the patched console values from the cached
settings store. However, if nothing has been stored, for example because
the frontend is outdated or has never synced its settings, then behavior
doesn't change.
* The devtools frontend sends no new messages. However, if it did send a
new message (e.g. "store this value at this key"), and the backend was
outdated, that message would be silently ignored.
* Facebook -> Meta in copyright
rg --files | xargs sed -i 's#Copyright (c) Facebook, Inc. and its affiliates.#Copyright (c) Meta Platforms, Inc. and affiliates.#g'
* Manual tweaks
This upgrade made more expressions invalidate refinements. In some
places this lead to a large number of suppressions that I automatically
suppressed and should be followed up on when the code is touched.
I think most of them might require either manual annotations or moving
a value into a const to allow refinement.

Pull Request resolved: https://github.com/facebook/react/pull/25410
Rationale: The only case where the unsupported dialog really matters is React Naive. That's the case where the frontend and backend versions are most likely to mismatch. In React Native, the backend is likely to send the bridge protocol version before sending operations– since the agent does this proactively during initialization.
I've tested the React Native starter app– after forcefully downgrading the backend version to 4.19.1 (see #23307 (comment)) and verified that this change "fixes" things. Not only does DevTools no longer throw an error that causes the UI to be hidden– it works (meaning that the Components tree can be inspected and interacted with).
* 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
Co-authored-by: Andrew Clark <git@andrewclark.io>
* 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
Update all our local scripts to use `build` instead of `build2`.
There are still downstream scripts that depend on `build2`, though, so
we can't remove it yet.

This PR adds separate DevTools feature flag configurations for react-devtools-core. It also breaks the builds down into facebook specific and open source flags so we can experiment in React Native.
Tested yarn build:standalone, yarn build:backend, yarn build:standalone:fb, and yarn build:backend:fb and inspected the output to make sure each package used the correct feature flags (the first two use core-oss and the latter two use fb-oss.
React currently suppress console logs in StrictMode during double rendering. However, this causes a lot of confusion. This PR moves the console suppression logic from React into React Devtools. Now by default, we no longer suppress console logs. Instead, we gray out the logs in console during double render. We also add a setting in React Devtools to allow developers to hide console logs during double render if they choose.
The following APIs have been added to the `react` stable entry point:
* `SuspenseList`
* `startTransition`
* `unstable_createMutableSource`
* `unstable_useMutableSource`
* `useDeferredValue`
* `useTransition`
The following APIs have been added or removed from the `react-dom` stable entry point:
* `createRoot`
* `unstable_createPortal` (removed)
The following APIs have been added to the `react-is` stable entry point:
* `SuspenseList`
* `isSuspenseList`
The following feature flags have been changed from experimental to true:
* `enableLazyElements`
* `enableSelectiveHydration`
* `enableSuspenseServerRenderer`
Add an explicit Bridge protocol version to the frontend and backend components as well as a check during initialization to ensure that both are compatible. If not, the frontend will display either upgrade or downgrade instructions.
Note that only the `react-devtools-core` (React Native) and `react-devtools-inline` (Code Sandbox) packages implement this check. Browser extensions inject their own backend and so the check is unnecessary. (Arguably the `react-devtools-inline` check is also unlikely to be necessary _but_ has been added as an extra guard for use cases such as Replay.io.)
React has its own component stack generation code that DevTools embeds a fork of, but both of them use a shared helper for disabling console logs. This shared helper is DEV only though, because it was intended for use with React DEV-only warnings and we didn't want to unnecessarily add bytes to production builds.
But DevTools itself always ships as a production build– even when it's used to debug DEV bundles of product apps (with third party DEV-only warnings). That means this helper was always a noop.
The resolveCurrentDispatcher method was changed recently to replace the thrown error with a call to console.error. This newly logged error ended up slipping through and being user visible because of the above issue.
This PR updates DevTools to also fork the console patching logic (to remove the DEV-only guard).
Note that I didn't spot this earlier because my test harness (react-devtools-shell) always runs in DEV mode. 🤡
