David Aurelio a72c2950d6 babel-preset-react-native: Make sure that `react-transform-hmr/lib/index.js` is included correctly for every module in the bundle Summary:This imports `react-transform-hmr/lib/index.js` with a relative path from every module, to make sure we don’t rely on the current (broken) behaviour. It works now, because: - the dependency is added by a transform - we extract dependencies before transforming - we include `react-transform-hmr/lib/index.js` manually - packager incorrectly names modules by the name of their package (i.e. packages with multiple versions overwrite each other) This blocks transforming before extracting dependencies, switching to numeric module IDs, and unbundling/random access bundles.

babel-preset-react-native

Babel presets for React Native applications. React Native itself uses this Babel preset by default when transforming your app's source code.

If you wish to use a custom Babel configuration by writing a .babelrc file in your project's root directory, you must specify all the plugins necessary to transform your code. React Native does not apply its default Babel configuration in this case. So, to make your life easier, you can use this preset to get the default configuration and then specify more plugins that run before it.

Usage

As mentioned above, you only need to use this preset if you are writing a custom .babelrc file.

Installation

Install babel-preset-react-native in your app:

npm i babel-preset-react-native --save-dev

Configuring Babel

Then, create a file called .babelrc in your project's root directory. The existence of this .babelrc file will tell React Native to use your custom Babel configuration instead of its own. Then load this preset:

{
  "presets": ["react-native"]
}

You can further customize your Babel configuration by specifying plugins and other options. See Babel's .babelrc documentation to learn more.
