Babel Run utils

This folder contains various pieces to make using Babel with our Babel preset easier, without the need for Babel configurations in every module.

CLI

You can run scripts written in ES6 directly from the command line:

$ ../babel-run/babel-node my_script.js

The babel-node wrapper modifies CLI arguments as if node were executing the script directly. If you need to run the script without altered arguments (for e.g. cluster.fork() expects unaltered arguments) you may want to use babel-node-allargs wrapper:

$ ../babel-run/babel-node-allargs my_script.js

Shebang

Both babel-node and babel-node-allargs can be used in a shebang line so you can directly create executable scripts written in ES6:

#! /usr/bin/env ../pub/babel-run/babel-node

console.log(`This is ES6 Code`);

Custom wrapper scripts

If you need to do additional things besides Babelifying the code, you may want to write your own wrapper script rather than using babel-node or babel-node-allargs.

#!/usr/bin/env node

'use strict';

require('../babel-run/node')();
doAdditionalStuff();
require('./myscript');

Mocha:

For example you can use the node.js file to setup a mocha environment, by adding a your-module/test/mocha.opts file:

--require ../../babel-run/mocha

Alternatively, you can refer to a dedicated JS module to set up the node environment if you wish to do additional stuff:

--require test/setup.js

test/setup.js would look similar to a CLI wrapper script:

require('../../babel-run/node')();
doAdditionalStuff();
