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.
