Add support for out-of-tree platform plugins (#20825)
Browse files Browse the repository at this point in the history
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: react-native-community/discussions-and-proposals#21
Pull Request resolved: #20825
