1. Adds an `unstable_experiments` option to `createDevMiddleware` in `react-native/dev-middleware`.
2. Adds `enableCustomDebuggerFrontend` (default `false` for now) as an experiment flag controlling whether the new debugger frontend (D48680624, D48682302) is in use. We plan to enable this by default in RN 0.73 after additional testing.
If enabled, the new debugger frontend will only be used for the `/open-debugger` flow

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39078
Simplifies and hardens behaviour for detecting other processes / dev server instances when running `react-native start`.
- New flow:
- Exits with error message if port is taken by another process (*no longer suggests next port*).
- Exits with info message if port is taken by another instance of this dev server (**unchanged**).
- Continues if result unknown.
- *(No longer logs dedicated message for another RN server running in a different project root.)*
- This now checks if the TCP port is in use before attempting an HTTP fetch.
Previous behaviour: [`handlePortUnavailable`](7342221187/packages/cli-tools/src/handlePortUnavailable.ts (L8)). This decouples us from some lower-level `react-native-community/cli-tools` utils, which remain reused by the `android` and `ios` commands.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39107
Augments D48466760 to report debugger commands (request/response pairs) through `EventReporter`. With the appropriate backend integration, this can help validate the correctness/completeness of the CDP implementation (in the client, proxy and server) and measure the latency of debugger commands - more accurately, the time between the proxy receiving a command from the client and receiving the corresponding response from the server.
Most of the new logic here is in the `DeviceEventReporter` class, which is responsible for associating responses with requests. Requests are kept in a buffer with a 10s TTL which serves as a timeout in case of an unresponsive server.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/38990
This PR adds auto-generation of Typescript definitions from Flow source code for packages using the shared monorepo build setup (https://github.com/facebook/react-native/pull/38718).
Today, these are the following Node.js packages:
- `packages/community-cli-plugin`
- `packages/dev-middleware` (⬅️ `emitTypeScriptDefs` enabled)
This also improves emitted Flow definitions (`.js.flow`), by using [`flow-api-translator`](https://www.npmjs.com/package/flow-api-translator) to strip implementations.
**All changes**
- Include `flow-api-translator` and configure this to emit type definitions as part of `yarn build`.
- Add translation from Flow source to TypeScript definitions (`.d.ts`) adjacent to each built file.
- Improve emitted Flow definitions (`.js.flow`), by using `flow-api-translator` to strip implementations (previously, source files were copied). The Flow and TS defs now mirror each other.
- Add `emitFlowDefs` and `emitTypeScriptDefs` options to build config to configure the above.
- Integrate TypeScript compiler to perform program validation on emitted `.d.ts` files.
- This is based on this guide: https://github.com/microsoft/TypeScript-wiki/blob/main/Using-the-Compiler-API.md#a-minimal-compiler.
- Throw an exception on the `rewritePackageExports` step if a package does not define an `"exports"` field.
- Add minimal `flow-typed` definitions for `typescript` 😄.
**Notes on [`flow-api-translator`](https://www.npmjs.com/package/flow-api-translator)**
This project is experimental but is in a more mature state than when we evaluated it earlier in 2023.
- It's now possible to run this tool on our new Node.js packages, since they are exclusively authored using `import`/`export` syntax (a requirement of the tool).
- As a safety net, we run the TypeScript compiler against the generated program, which will fail the build.

## Context
RFC: Decoupling Flipper from React Native core: https://github.com/react-native-community/discussions-and-proposals/pull/641
## Changes
Inits new package `react-native/community-cli-plugin`. This migrates [`react-native-community/cli-plugin-metro`](https://github.com/react-native-community/cli/tree/main/packages/cli-plugin-metro) into the React Native repo, to enable faster iteration by the React Native core team. Specifically:
- This package contains several `metro` dependencies, which when removed from CLI will no longer require us to ship new CLI releases to get Metro patches and features to users.
- This package contains the `start`, `bundle`, and `ram-bundle` commands (central to the React Native development experience), for which we have incoming debugging-related changes.
- This package now **only** exports commands to be attached via a RN CLI plugin. With this move, we're aiming to **internalise** the default implementations of these dev commands within React Native — other RN CLI plugins can continue to override these, but must do so wholesale. (See also the recent fix for this: https://github.com/react-native-community/cli/pull/1999.)
In V15:
- (Microsoft feedback) Re-export `unstable_buildBundleWithConfig`, marking as unstable. This gives us a time buffer to consider how we repackage this functionality in future.
The package source has been converted from TypeScript to Flow, with a number of new `flow-typed/` defs added to meet type coverage requirements.
## To dos
- For now, we aren't removing the existing [`react-native-community/cli-plugin-metro`](https://github.com/react-native-community/cli/tree/main/packages/cli-plugin-metro) source — until later PRs consolidate this move by changing dependencies in the `react-native` package.
- **Exported API is reduced!**: I'm working with szymonrybczak to decouple references from RN CLI packages https://github.com/react-native-community/cli/pull/2021.

## Context
RFC: Decoupling Flipper from React Native core: https://github.com/react-native-community/discussions-and-proposals/pull/641
## Changes
To support incoming new React Native packages around debugging (including migrating over [`react-native-community/cli-plugin-metro`](https://github.com/react-native-community/cli/tree/main/packages/cli-plugin-metro)) — which target Node.js and require a build step, this PR adds a minimal shared build setup across the `react-native` monorepo.
The setup is closely inspired/based on the build scripts in Jest, Metro, and React Native CLI — and is a simple set of script wrappers around Babel. These are available as build commands at the root of the repo:
- `yarn build` — Builds all configured packages. Functionally, this:
- Outputs a `dist/` directory with built files.
- Rewrites package.json `"exports"` to update every `./src/*` reference to `./dist/*` (source of truth).
- `scripts/build/babel-register.js` — Allows running all Node.js entry points from source, similar to the current setup in [facebook/metro](https://github.com/facebook/metro). (Example entry point file in this PR: `packages/dev-middleware/src/index.js`)
Build configuration (i.e. Babel config) is shared as a set standard across the monorepo, and **packages are opted-in to requiring a build**, configured in `scripts/build.config.js`.
```
const buildConfig /*: BuildConfig */ = {
// The packages to include for build and their build options
packages: {
'dev-middleware': {target: 'node'},
},
};
```
For now, there is a single `target: 'node'` option — this is necessary as `react-native`, unlike the above other projects, is a repository with packages targeting several runtimes. We may, in future, introduce a build step for other, non-Node, packages — which may be useful for things such as auto-generated TypeScript definitions.
{F1043312771}
**Differences from the Metro setup**
- References (and compiles out) repo-local `scripts/build/babel-register.js` — removing need for an npm-published dependency.
## Current integration points
- **CircleCI** — `yarn build` is added to the `build_npm_package` and `find_and_publish_bumped_packages` jobs.
**New Node.js package(s) are not load bearing quite yet**: There are not yet any built packages added to the dependencies of `packages/react-native/`, so this will be further tested in a later PR (and is actively being done in an internal commit stack).
### Alternative designs
**Per-package config file**
Replace `scripts/build/config.js` with a package-defined key in in `package.json`, similar to Jest's [`publishConfig`](1f019afdcd/packages/jest-cli/package.json (L87C3-L89C4)).
```
"buildConfig": {
"type": "node"
},
```
This would be the only customisation required, with a single Babel config still standardised. Another option this might receive in future is `enableTypeScriptCodgeen`.
**Rollup**
More sophisticated build tool for Node.js, used by the React codebase (albeit within a custom script setup as well).
**Lerna and Nx**
- Most sophisticated setup enabling caching and optimised cloud runs.
- Probably the most likely thing we'll move towards at a later stage.

Summary:
Generating this diff was difficult. We _will_ fix the issues with jscodeshift, but i don't want to block the syntax change on that.
To get this diff, I first codemodded all of xplat to use exact-by-default. Then i turned on implicit-inexact-object:error enforcement to get a list of errors showing places that violated the lint. With that, I used this to generate a list of `sed` commands to add `...`:
```
flow --json | jq '.errors | .[] | .message | .[] | .loc | {source, "line": .end."line", "column": .end."column"} | "\(.column),\(.line),\(.source)"' | sort -n -r | sed 's/"//g' | while read -r line; do echo $line; awk -F',' "{ print \"sed -i '\"\$2\"s/./...&/\"\$1\"' \" \$3 }"; done
```
Then I ran prettier, reverted generated files, and manually fixed up suppressions that got messed up.
