babel-preset-env

babel-preset-blueflag uses babel-preset-env to automatically determine the Babel plugins and polyfills you need based on your supported environments. By default if browser is set to true then the env settings will be:

{
  "targets": {
    "browsers": ["last 2 versions"]
  }
}

otherwise they will be:

{
  "targets": {
    "node": "current"
  }
}

Configuration

babel-preset-blueflag can be configured to provide different plugins and presets, as well as to pass configuration to those plugins and presets.

Configuration can be passed by wrapping the preset in an array and placing a configuration object as the second item in the array.

{
    presets: [
        ['blueflag', {

        }]
    ]
}

The follow options are supported:

library

boolean - defaults to false.

Doesn't do anything at the moment.

browser

boolean - defaults to false

Whether this project is to be used in a browser. If set to true then babel-preset-env's target will be set to target the last 2 versions of major browsers.

disabled

String[] - defaults to []

An array of plugins/presets that shouldn't be enabled. The plugin/preset prefix should be excluded, eg. ['env', 'transform-runtime', 'transform-class-properties', 'react', 'stage-3']

config

Object - defaults to {}

An object containing configuration to be passed on to the preset's child plugins and presets. eg.

{
    presets: [
        ['blueflag', {
            config: {
                env: {
                    targets: {
                        browsers: 'last 3 versions'
                    }
                }
