empyrical 03476a225e Add support for out-of-tree platform plugins (#20825)
Summary:
This pull request adds the ability for a platform developer to provide a `"haste"` key under the `"rnpm"` key in their `package.json` which allows the packager to pick up that platform's javascript files. The intent is to remove the need to have custom platforms hardcoded in. This is inspired by the `"jest": { "haste": {} }` key used by jest.

For example, React Native Dom would have an entry like:

```json
{
  "rnpm": {
    "haste": {
      "providesModuleNodeModules": [
        "react-native-dom"
      ],
      "platforms": [
        "dom"
      ]
    }
  }
}
```

Support for more keys (path blacklists perhaps?) could be added in the future.

This succeeds #20662, as per a discussion I had with matthargett.

I've got an open discussion over here as well: https://github.com/react-native-community/discussions-and-proposals/issues/21

Eli White d2c27f5bff Remove view configs from JS
Summary: Apparently different apps have different implementations of view managers that support different props. This is a problem that we will need to address. Unfortunately, this means we can't have a static config defined in JS. We will need to find another approach to this problem.

Rafael Oleza dd0900a03a Standarize options passed to the transformer
Summary:
This is the first step to make transformers fully customizable (and not be tied to JS, or RN). In order to do that, I'm changing the signature of the transformers, which currently is:

```
function transformCode(
  filename: string,
  localPath: LocalPath,
  transformerPath: string,
  options: WorkerOptions,
  assetExts: $ReadOnlyArray<string>,
  assetRegistryPath: string,
  minifierPath: string,
  asyncRequireModulePath: string,
  dynamicDepsInPackages: DynamicRequiresBehavior,
)
```

to be:

```
async function transformCode(
  filename: string,
  localPath: LocalPath,
  options: WorkerOptions,
)
```

(so basically, all the RN-custom properties are moved to `WorkerOptions`, which in the future will be a generic to allow anybody pass any random option to their transformers).

In order to make all this work, I've had to get rid of the logic that calculates the base cache key hash based on a subset of worker options (the ones that Metro knows that are not going to change between runs).

This could potentially cause a perf regression (since we're now making the hash calculation a bit more costly), and in fact I could measure a ~400ms regression on the worse case scenario (which happens when restarting Metro and re-transforming a Wilde from a warm local cache).

I've benchmarked this regression and could find that it's caused by the array of `assetExtensions` (which is potentially large). I have a followup diff to improve this, which is able to remove the regression completely.

Vincent Riemer c4bcca6685 Whitelist react-native-dom in haste/cli config defaults (#20393)
Summary:
This adds `react-native-dom` to `hasteImpl.js` because it's not currently possible to configure it from an out of tree platform. Also adds the relevant `providesModuleNodeModules` and `platforms` values to the default RN CLI config. This should hopefully be able to be removed once better support for out of tree platforms is implemented.

Rubén Norte 54942746d4 Hotfix to include react-native-windows in hasteImpl accepted paths (#20007)
Summary:
Closes https://github.com/facebook/react-native/pull/20007

We removed support for providesModule annotations and maintained support for Haste names in installed modules via `providesModuleNodeModules`, but our default `hasteImpl` doesn't take them into account. We need to find a better way to override core components from plugins but meanwhile this adds an exception for react-native-windows in the default `hasteImpl` to unblock their upgrade to the latest RC.

Peter van der Zee 7014a30baa Upgrade babel to beta.47 across xplat
Summary:
Upgrade Babel from beta.40 to beta.47

There are two important breaking changes here.

- If you want an AST from the Babel `transform` functions you must pass on `ast:true` in the options.
- The `sourceType` is now the only source of truth on whether to parse with the Script or Module goal. It defaults to `script` and can also be `module` or `unambiguous`. In the `unambiguous` case it will first try to parse with the Module goal and only if it crashes it will try again with the Script goal.

Beyond that there were some fixes and some smaller changes that may affect you. See the Babel changelogs for details (https://github.com/babel/babel/tags).

Also updated the way we generate the babel helpers file.

* Checked the Flow configuration by running flow on the project root (no errors):

```
yarn flow
```

* Checked the Jest configuration by running the tests with a clean cache:

```
yarn jest --clearCache && yarn test
```

* Checked the Metro configuration by starting the server with a clean cache and requesting some bundles:

```
yarn run start --reset-cache
curl 'localhost:8081/IntegrationTests/AccessibilityManagerTest.bundle?platform=android'
curl 'localhost:8081/Libraries/Alert/Alert.bundle?platform=ios'

```jsx
import React, { Component } from 'react';
import { AppState } from 'react-native';

class TestComponent extends Component {
  componentDidMount() {
    AppState.addEventListener('change', this.stateChangeListener);
  }
  componentWillUnmount() {
    AppState.removeEventListener('change', this.stateChangeListener);
  }
}
```

It should pass test using Jest (snapshots)

It's the continuation of #11199. This PR finish the mock for the native module `AppState`.

James Ide af6450c660 Add back support for the assetPlugin option
Summary:
**Summary**
Metro used to have support for "asset plugins", which allowed developers to specify arbitrary JS modules that could export a function for adding more fields to asset data objects. Some of this functionality was removed in the delta bundler work -- this PR adds it back.

**Test plan**
Made existing unit tests pass and added unit tests to test asset plugin behavior. Also tested E2E in a React Native project by adding `assetPlugin=/path/to/pluginModule` to a JS bundle URL and ensuring that the plugin ran.
Closes https://github.com/facebook/metro/pull/118

Maksym Rusynyk 3088096684 Return request id in jest mock for requestAnimationFrame
Summary:
`Jest` allows to use fake timers and according to https://developer.mozilla.org/en-US/docs/Web/API/Window/requestAnimationFrame the return value should be `A long integer value, the request id, that uniquely identifies the entry in the callback list`. This allows to use `cancelAnimationFrame`.

In current implementation of `jest/setup.js`, the return value is undefined. Therefore it's not possible to cancel the animation frame request.

```
let id = null;
const registerCallback = (callback) => {
  clearCallback();
  id = requestAnimationFrame(() => {
    id = null;
    callback();
  });
};
const clearCallback = () => {
  if (null !== id) {
    cancelAnimationFrame(id);
    id = null;
  }
};
```

```
jest.useFakeTimers();

const callback = jest.fn();
registerCallback(callback);
clearCallback();

jest.runAllTimers();
expect(callback).toHaveBeenCalledTimes(0); // Will be error in current implementation, since nothing is cleared. And test will pass, after MR is merged
```

This is fake example, but the real usage is when the animation frame request should be removed on `ComponentWillUnmount`.

Julien Moutte bbceb48dbb Direct assignment of the ref to avoid warning when mocking.
Summary:
When Jest is mocking native components that are assigned a ref with an arrow function, a warning is generated about stateless components which can not have a ref. This does not happen when the ref is assigned directly.

Fixes #16045.

The test provided in the related issue is used to validate the fix. I don't know how to detect console warnings in a Jest test.
