duo-babel

duo-plugin for babel.

Installation

$ npm install duo-babel

Usage

From the CLI:

$ duo --use duo-babel

Using the API:

var Duo = require('duo');
var babel = require('duo-babel');

Duo(__dirname)
  .entry('index.js')
  .use(babel())
  .run(function (err, results) {
    // ...
  });

API

babel([options])

Initialize a duo plugin. Available options:

extensions a list of file extensions that should be transpiled (default: ['.js', '.jsx', '.es', '.es6'])
onlyLocals specify that any remotes should not be transpiled
only a list of glob patterns to only transpile
ignore a list of glob patterns to not transpile (the opposite of only)
anything else is passed directly to babel

Selective Transpiling

In many cases, onlyLocals is needed early on. Your local scripts need to be transpiled, but most of your dependencies don't need it. However, as time goes on and you publish your own dependencies using ES6, you'll need something more selective.

You can add an array as either only or ignore (not both) to selectively enable babel's transpilation.

Your patterns should match the directory structure that duo uses. (and that you can see on disk)

lib/**.js will match any JS file in the local lib dir
components/lodash-lodash@*/**.js will match any version of lodash
components/component-*/**.js will match anything in the component organization.

Source Maps

ES6 source-maps are turned on automatically when duo has enabled source-maps, this feature can be disabled by explicitly setting the sourceMaps option.
