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.
