Targeting Environments

This module uses @babel/preset-env to target specific environments.

Please refer to @babel/preset-env#targets for a list of available options.

For a list of browsers please see browserlist.

You may override our default list of targets by providing your own targets key.

{
  "presets": [["babelbing", {
    "targets": {
      "chrome": 50,
      "explorer": 11,
      "firefox": 45
    }
  }]]
}

The following transpiles only for Node v6.

{
  "presets": [["babelbing", {
    "targets": {
      "node": 6
    }
  }]]
}

If you wish, you can also inherit our default list of browsers and extend them using additionalTargets.

{
  "presets": [["babelbing", {
    "additionalTargets": {
      "chrome": 42,
      "explorer": 8
    }
  }]]
}

You may override our default debug option by providing your own debug key.

{
  "presets": [["babelbing", {
    "debug": true
  }]]
}

React Development Mode

When process.env.NODE_ENV is 'development', the development mode will be set for @babel/preset-react.

You may override our default development option by providing your own boolean development key.

{
  "presets": [["babelbing", {
    "development": false
  }]]
}

React PropTypes removal

This preset can be configured to remove propTypes using babel-plugin-transform-react-remove-prop-types with the following default options:

To enable this transformation with the default options, set the removePropTypes option to true:

{
  "presets": [["babelbing", {
    "removePropTypes": true
  }]]
}

The default options that will be used are:

{
  mode: 'wrap',
  ignoreFilenames: ['node_modules'],
}

Default options can be overridden using the removePropTypes option. These options will be shallow-merged with the defaults:

{
  "presets": [["babelbing", {
    "removePropTypes": {
      "mode": "remove"
    }
  }]]
}

For example, if you are using this plugin in a deployable app, you might want to use the remove mode for your production build (and disable this transform entirely in development for optimal build speeds).
