babel-asset-pipeline

babel.js transformation for asset-pipeline

usage

simply add

compile 'net.errbuddy.plugins:babel-asset-pipeline:1.3.0'

to dependencies

and

maven { url "http://dl.bintray.com/errbuddy/plugins" }

to you repositories in build.gradle. The plugin will ONLY process .es6 and .jsx files if not otherwise told.

Configuration

Important

although you can define options in application.yml (or .groovy) it is recommended to configure those options in build.gradle in the "assets" block as otherwise configuration parameters are not picked up during grails war or gradle assetCompile. E.g:

assets {
    minifyJs = true
    minifyCss = true
    configOptions = [
        babel: [
            enabled: true,
            processJsFiles: true,
            options: [
                blacklist: ['useStrict'],
                loose: 'all'
            ]
        ]
    ]
}

Options

grails.assets.babel.enabled = true // boolean

default to true. enables the plugin

grails.assets.babel.processJsFiles = false // boolean

defaults to false. Whether to process JsAssetFiles (.js) too. By default to Processor only touches Es6AssetFiles (.es6)!

grails.assets.babel.options = [blacklist: ['useStrict'], loose: 'all'] // babel transfom options. see https://babeljs.io/docs/usage/options/ for more information

defaults to null. A Map of options passed to babels transform method. see https://babeljs.io/docs/usage/options/ for possible values

Modules

grails.assets.babel.options = [modules: 'amd', moduleIds: true]

When the moduleIds option is set the plugin provides Babel with a moduleId for each file. The ID is the relative path of the file inside grails-app/assets/javascripts with the file extension removed.

e.g.
# File Path:
grails-app/assets/javascripts/foo/bar.js
# Generated moduleId:
foo/bar
