Boilerplate with Maki Module

TL;DR: Make flexible and consistent folder-based modular boilerplate with Maki Module :)

In programming there is boilerplate:

sections of code that have to be included in many places with little or no alteration.


Since most things being made follow a pattern of things made before them, boilerplate gives a project consistency and sets the expectations of what you may find in other files, functions, classes, etc.

Shell commands with Node

Running CLI Node scripts, capture the return value of a shell command:

const execSync = require('child_process').execSync;
const nodeVer = execSync('node -v', { encoding: 'utf8' });

Shell command reports in the CLI:

const execSync = require('child_process').execSync;
execSync('npm -g ls', { stdio: 'inherit' });

Validate the Crickets’ Nest

I have a problem getting values from deeply nested objects: if one of the properties along the namespace is incorrect|modified|removed, Javascript throws. To avoid this, you can end up with obnoxious validation:

// Trying to get
const isValid = (
  typeof === 'object' &&
  typeof === 'object' &&
  typeof === 'object' &&
  typeof === 'string'
if (isValid) {
  const { name } =;

What if I made a reusable helper to validate the namespace and return the value?

export default function getNamespace(startObj, path) {
  const isValidArgs = (
    typeof startObj === 'object' &&
    typeof path === 'string'
  if (!isValidArgs) return undefined;

  const finalValue = path
    .reduce((obj, p) => ((typeof obj === 'object') 
      ? obj[p]
      : undefined
    ), startObj);{

  return finalValue;

Now the obnoxious validation looks like this:

// Trying to get
const name = getNamespace(this, '');
if (name) { ... }

Dude! Sweet!

Alias for Git sanity

Git command line is pretty confusing. Here are some aliases that I found helpful that normalize it with other command line commands and add a little bit better context.

Open global .gitconfig file:

$ open ~/.gitconfig

If there isn’t an [alias] section already, add one:

  cd = checkout
  ll = branch
  ls = branch
  delete-merged = !git branch --merged | egrep -v \"(^\\*|master|development)\" | xargs git branch -d
  new-up = !git push -u origin `git symbolic-ref --short HEAD`
  stage = add
  unstage = reset HEAD
