## 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

## 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
<!--
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?
<!--
Demonstrate the code is solid. Example: The exact commands you ran and
their output, screenshots / videos if the pull request changes the user
interface.
How exactly did you verify that your PR solves the issue you wanted to
solve?
If you leave this empty, your PR will very likely be closed.

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.
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.

* Manual tweaks
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

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.)
This commit adds a new tab to the Settings modal: Debugging
This new tab has the append component stacks feature and a new one: break on warn
This new feature adds a debugger statement into the console override
This dialog is shown in the browser extension the first time a user views v4. It is off by default for the standalone extension, but can be enabled via a public API.
But only do this if we can verify the element file path. This hopefully avoids the case where clicking the button does nothing because of an invalid/incomplete path.
* Added shadow to modals
* Change default "collapse new nodes" to be disabled rather than enabled
* Changed setting label "Collapse newly added components by default" to "Expand component tree by default"
* Change CSS media query for settings popup to show labels at smaller size
* Hide "Inspect the matching DOM element" button (since it doesnt really serve a purpose in standalone)
* Fixed small size bug for settings icon (viewbox of 20x20 instead of 24x24)
* bugfix: window.addEventListener/window.removeEventListener is not defined in Hermes.
* Patch console.warn and console.error to auto-append owners-only component stacks.
This setting is enabled by default and will work for React Native even if no front-end DevTools shell is being used. The setting can be disabled via a new, persisted user preference though.
* Add version 4 react-devtools and react-devtools-core packages which support both React Native and e.g. Safari or iframe DOM usage.
* Replaces typed operations arrays with regular arrays in order to support Hermes. This is unfortunate, since in theory a typed array buffer could be more efficiently transferred between frontend and backend for the web extension, but this never actually worked properly in v8, only Spidermonkey, and it fails entirely in Hermes so for the time being- it's been removed.
* Adds support for React Native (paper renderer)
* Adds a style editor for react-native and react-native-web
