It's now here, in The Programmer's Compendium. The content is the same as before, but being part of the compendium means that it's actively maintained.

Recently when refactoring a Vue 1.0 application, I utilized ES6 arrow functions to clean up the code and make things a bit more consistent before updating to Vue 2.0. Along the way I made a few mistakes and wanted to share the lessons I learned as well as offer a few conventions that I will be using in my Vue applications moving forward.

The best way to explain this is with an example so lets start there. I'm going to throw a rather large block of code at you here, but stick with me and we will move through it a piece at a time.

<script>

// require vue-resource...

new Vue({

	#!/bin/sh

	# This script runs every other night at 04:56 CET on a webserver I maintain
	# Results are always at: https://jult.net/block.txt ( or https://jult.net/block.txt.gz )
	# And much smaller, stripped of BS; https://jult.net/bloc.txt
	# For use in Tixati IP filter: https://jult.net/bloc.txt.gz !!!
	# And finally a txt file with just the bold IP-ranges: https://jult.net/bl.txt (or https://jult.net/bl.txt.gz )

	# Download open block-lists, unpack, filter:
	curl -s https://www.iblocklist.com/lists.php \| grep -A 2 Bluetack \| xargs wget -qO - --limit-rate=500k \| gunzip -f \| egrep -v '^#' > /tmp/xbp
