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.

Read this first!

Hi there! Since this post was originally written, nvm has gained some new tools, and some people have suggested alternative (and potentially better) approaches for modern systems. Make sure to have a look at the comments to this article, before following this guide!

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

# The command finds the most recent tag that is reachable from a commit.
# If the tag points to the commit, then only the tag is shown.
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object 
# and the abbreviated object name of the most recent commit.
git describe

# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
git describe --abbrev=0

Publishing an NPM package

Here's what I do when I publish an NPM package.

1: Make sure you're up to date

I always like to check what's going on in a repo before I do anything:

cletusw

{
  // http://eslint.org/docs/rules/

  "ecmaFeatures": {
    "binaryLiterals": false,                    // enable binary literals
    "blockBindings": false,                     // enable let and const (aka block bindings)
    "defaultParams": false,                     // enable default function parameters
    "forOf": false,                             // enable for-of loops
    "generators": false,                        // enable generators
    "objectLiteralComputedProperties": false,   // enable computed object literal property names
