Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51836
Currently, `community-cli-plugin` loads the user config and then overrides parts of it - specifically `resolver.resolveRequest` and `serializer.getModulesRunBeforeMainModule`, making it impossible for a user to modify this config.
Instead, treat the CLI's resolver and serializer customisations as "Framework defaults", layered on top of `react-native/metro-config` defaults but beneath a user's `metro.config.js`.
This allows the user to obtain (via `react-native/metro-config`'s `getDefaultConfig`) and extend or override them, if they need to.
This is technically breaking because users who currently have a custom `resolveRequest` or `getModulesRunBeforeMainModule` in their `metro.config.js` will have that config respected from this change, whereas currently they won't have any effect.
Changelog:
[General][Breaking] Community CLI users: user-defined `resolver.resolveRequest` and `serializer.getModulesRunBeforeMainModule` Metro config now takes precedence over CLI defaults

Now that we have `babel-plugin-syntax-hermes-parser` in `react-native/babel-preset` (since D63535216), it's no longer necessary to use `hermes-parser` directly in Metro in order to use newer Flow syntax.

See https://github.com/facebook/hermes/issues/1549 for context.

Summary:
React Native [app template provided by the CLI](https://github.com/react-native-community/template) currently uses [`metro-config` directly for `MetroConfig` type](https://github.com/react-native-community/template/blob/main/template/metro.config.js#L7).
However, it doesn't have `metro-config` as neither a dependency or dev dependency, which can lead to version mismatches.
While this is obviously a mistake on the template repo side, `metro-config` versions aren't matched with `react-native` versions. Therefore, getting the correct version of `metro-config` from `react-native/metro-config` would require reflecting on `react-native/metro-config`'s package.json etc. which is far from ideal. In my opinion it's would be much better to expose `MetroConfig` type from `react-native/metro-config` directly.
Version mismatching can happen in a monorepo setup. Say we have the monorepo structure using Yarn Modern:
```tree
.
├── RN75-app (workspace)
├── RN76-app (workspace)
│ ├── metro.config.js
│ └── node_modules
│ └── react-native
│ └── metro-config (0.76)
│ └── node_modules
│ └── metro-config (version for 0.76)
└── node_modules
├── react-native
│ └── metro-config (0.75)
└── metro-config (version for 0.75)
```
`react-native@0.75` gets hoisted to the monorepo root while `react-native@0.76` sits in an RN 0.76 app workspace.
Say we have the following `RN76-app/metro.config.js` contents:
```js
const {getDefaultConfig, mergeConfig} = require('react-native/metro-config');
/**
* Metro configuration
* https://reactnative.dev/docs/metro
*
* type {import('metro-config').MetroConfig}
*/
const config = {};
module.exports = mergeConfig(getDefaultConfig(__dirname), config);
```
In this case, `require('react-native/metro-config')` would resolve to `RN76-app/node_modules/react-native/node_modules/metro-config` since `react-native/metro-config` is a (dev) dependency of the App.
However `import('metro-config).MetroConfig` would resolve to `node_modules/metro-config` since it's not a direct dependency.
This is how we have a mismatch - imported functions come from different packages than imported type.
## Changelog:
[GENERAL] [ADDED] - Expose `MetroConfig` type directly from `react-native/metro-config`.
Pull Request resolved: https://github.com/facebook/react-native/pull/46602
Test Plan:
`yarn build` to generate dist for `react-native/metro-config`, see it has the export of `MetroConfig`.
## Notes
If this PR gets approved, I'll submit relevant one to the CLI template.

This likely only affects Meta usage, since Metro's default for [`isThirdPartyModule`](https://metrobundler.dev/docs/configuration/#isthirdpartymodule) already excludes all `node_modules`, but I'm making this change across Meta and OSS for consistency and to signal intent.

> Note, I also added the same `exports` block from `react-native/dev-middleware` for conformity.
One open question here is, why aren't we exporting _all_ helper functions from `metro-config`? To me, its a bit weird that we need both `metro-config` _and_ `react-native/metro-config` as `loadConfig` isn't exported.

Bump to the latest Metro release. This includes minor breaking changes to Metro subpackages that should *not* be visible to RN users.
Metro release notes: https://github.com/facebook/metro/releases/tag/v0.80.0
## Moving to unpinned versioning
Metro is a multi-package project, and not pinning to an exact version means multiple versions of `metro*` packages may appear in an RN project.
This isn't unusual in the NPM ecosystem and *shouldn't* be a problem, but historically has caused issues (eg https://github.com/facebook/react-native/issues/34714, https://github.com/facebook/metro/issues/1017). The root cause of all of these issues, as far as we know, was fixed in https://github.com/facebook/metro/commit/6d46078e74ae9a43aa90bed46dbd6610e2696cd0, a bug where Node hierarchical resolution was effectively sidestepped via a relative worker path, resulting in a mismatch between transformer and host process.
In addition, the fact that `react-refresh`, `metro-react-native-babel-transformer` and `metro-react-native-babel-preset` are now fully moved into the `react-native/` scope and versioned with React Native means there are no circular dependencies between React Native and Metro, explicit or implicit, and we're much more clearly decoupled.
So, we're moving to caret versioning to allow React Native users to pick up Metro fixes and features without requiring React Native releases and user upgrades.
