A week's small victories: Angular, Equality and Testing

Our work weeks are made up of victories both big and small. What really gets me writing is the small. The a-ha! moments. The high fives (internal ones count too). The green builds. The git pushes.

I spent my week creating dynamic forms and lists in Angular. I made them, fought with them, tested them, and came out the other side in one piece. Here's my story:

Writing and testing custom form validators

Custom form validators are a powerful feature in Angular.

	function snakeToCamelObjectKeys(obj) {
	return Object.keys(obj).reduce((output, key) => {
	let value = obj[key]

	const isObject = value.toString() === '[object Object]'
	if (isObject) {
	value = snakeToCamelObjectKeys(value)
	}

	const newKey = key.replace(/_(\w)/g, (match, $1) => $1.toUpperCase())

	const React = require('react')
	const ReactDomServer = require('react-dom/server')
	const fetch = require('node-fetch')

	function App(props) {
	const { repos } = props

	return React.createElement('p', {
	children: repos.length ? repos[0].name : 'no name',
	})

	import { columns, display, gridSpans, margin } from './css-modules-styles'

	const COLUMNS = 12

	const toArray = arrayLike => Array.prototype.slice.call(arrayLike)

	const placeItemsOnGrid = grid => {
	const withGutters = grid.classList.contains(columns.withGutters)
	let currentColumnSpansInRow = 0
	let currentRow = 1

	//@flow
	import React, { Component } from 'react'
	import type { ElementRef } from 'react'

	type Props = { src: string, alt: string }

	type State = { source?: string }

	export default class LazyImage extends Component<Props, State> {
	state = {}

	const { parse } = require('css')
	const { readdirSync, readFileSync } = require('fs')
	const { basename, extname, resolve } = require('path')
	const camel = require('lodash.camelcase')

	const baseNameForCSSFile = filename => basename(filename, '.css')

	const isAClassSelector = selector => /^\./.test(selector)

	const removeLeadingDotAndTrailingSelectors = selector =>

	{
	"rules": {
	"indent": [
	2, 2
	],
	"quotes": [
	2,
	"single"
	],
	"linebreak-style": [

	#!/bin/sh

	protectedBranch='master'
	currentBranch=$(git rev-parse --abbrev-ref HEAD)

	lastCommand=$(ps -ocommand= -p $PPID)
	disallowedCommand='force\|\-f'

	if [[ $lastCommand =~ $disallowedCommand ]] && [ $currentBranch = $protectedBranch ]; then
	echo "Force pushing to $protectedBranch is not allowed. Your push is rejected."
