1. Install prettier
2. Make a .prettierignore file, and add directories you'd like prettier to not format, for example: **/node_modules
3. Run prettier --write "**/*.js" *Don't forget the quotes.
4. Optional: if you want to format JSON/SCSS files too, replace js with json/scss.

Standard JS in create-react-app

I've been using create-react-app lately as I find it very useful to kick things off while starting a project. I almost always follow JavaScript Standard Style and I found myself googling it so I figured out I should write it down.

Get Standard JS

I really like keeping dependencies as local as possible but if you prefer you can install it globally.

yarn add standard --dev

[LINUX] Factorio Headless Server Guide

So, with credit to the Factorio wiki and cbednarski's helpful gist, I managed to eventually setup a Factorio headless server. Although, I thought the process could be nailed down/simplified to be a bit more 'tutorialised' and also to document how I got it all working for my future records.

The specific distro/version I'm using for this guide being Ubuntu Server 16.04.1 LTS. Although, that shouldn't matter, as long as your distro supports systemd (just for this guide, not a Factorio headless requirement, although most distros use it as standard now). The version of Factorio I shall be using is 0.14.20, although should work for any version of Factorio 0.14.12 and higher.

Just a note to newcomers: If there are any issues with the installation steps, people in the comments are doing a good job
