babel-globals

babel-globals

Compiles javascript files and all their dependencies with babel, outputing them as global variables.

##Usage This is a wrapper around babel for compiling a list of files and exposing the ES6 modules as global variables. After compiling all given files (and their dependencies, since we're using babel-deps), they are bundled into a single file. The return value of the function is an instance of Concat.

var babelGlobals = require('babel-globals');

var files = [
	{
		contents: fs.readFileSync(path1, 'utf8'),
		options: {filename: path1}
	},
	{
		contents: fs.readFileSync(path2, 'utf8'),
		options: {filename: path2}
	}
];

var bundle = babelGlobals(files, {
	bundleFileName: 'bundle.js',
	globalName: 'foo'
});
// Bundle will contain all the modules, which will be available at this.foo

API

files

An array of files to be compiled with their dependencies. Each element of the array should be an object with the following keys:

• contents {string} The code to be compiled.
• options {!Object} Options to be passed to babel when compiling this file. Note that the filename option is required.

options

An object with the following options:

• babel {Object=} An object with babel options that should be used for all files. File specific options will be merged with this before the file is compiled, so they have higher priority.
• bundleFileName {string=} The name of the bundled file. Defaults to bundle.js.
• globalName {string=} The name of the global variable the modules will be exported to. Defaults to myGlobals.
• skipGlobalVarInit {boolean=} If true, will not initialize the global variable. Set this to true if the variable will be initialized somewhere else.
