Minimum Viable Async with Node 6

With the release of Node 6.0.0, the surface of code that needs transpilation to use ES6 features has been reduced very dramatically.

This is what my current workflow looks like to set up a minimalistic and fast microservice using micro and async + await.

Effective transpiling of ES6

After publishing my article on ECMAScript 6, some have reached out to ask how I exactly I make it all work.

I refrained from including these details on the original post because they're subject to immiment obsoletion. These tools are changing and evolving quickly, and some of these instructions are likely to become outdated in the coming months or even weeks.

The main tool

When evaluating the available transpilers, I decided to use 6to5, which has recently been renamed to Babel. I chose it based on:

// Future versions of Hyper may add additional config options,
// which will not automatically be merged into this file.
// See https://hyper.is#cfg for all currently supported options.

module.exports = {
  config: {
    // default font size in pixels for all tabs
    fontSize: 14,

    // font family with optional fallbacks
