Bandolier

Bandolier takes modules with dependencies specified using ES6 import/export statements and returns a single script that can run in an pre-ES2015 JavaScript environment.

Installation

Install via maven:

mvn install

If you need to bundle the dependencies into a single jar:

mvn compile assembly:single

Usage

Running from the command line:

java -jar bandolier.jar path/to/file.js

Calling the static bundle method:

Script result = Bundler.bundle("/path/to/file.js");

Alternatively, if you have the file's contents handy you can use bundleString:

Script result = Bundler.bundleString("import { x } from \"foo\"; console.log(x);");

Both bundle and bundleString can be parameterized by an IResourceLoader (which tells the bundler how to load a resource referred to by some path) and an IResolver (which tells the bundler where to actually look for a resource referenced by some path). By default FileSystemResolver and FileLoader are used. Also available are a NodeResolver that follows node module resolving semantics and ClassResourceLoader for loading resources inside of jars.
