Show FPS for Steam Games

18.6.2018
There’s nothing more frustrating to a top gamer (outside of bugs in a game) than dropped frames in a video game. If you’re playing a competitive multiplayer game like PUBG or Fortnite, where up to 100 people are simultaneously competing, dropped frames can be the difference between...

Uppy File Uploading

11.6.2018
One of the big tasks I was charged with at my first job was setting up a system by which any customer or potential customer (aka anonymous user) could upload PDF and image files. I had loads of constraints to deal with: browser support, server settings, variance in user tech knowledge, etc....

console.logTime

7.6.2018
I work on a really complex debugger at Mozilla but, and don’t tell my colleagues, I sometimes enjoy simply using console.log and other console commands to get some simple output. I know, I know, but hey — whatever gets the job done. A few years ago I detailed console.time...

OpenRates Currency API (Sponsored)

30.5.2018
Creating your own APIs can be a total nightmare: worrying about uptime, load balancing, data accuracy, caching, and all of the other risks would keep me up at night. And if your API relates to money in any way? If you get that wrong you could be costing yourself, your employer, or your client...

How to Delete Untracked Files in a Mercurial Repository

29.5.2018
Working around Firefox at Mozilla means that you need to get acquainted with mercurial, the version control system that rivals git and svn. Like any tool, hg (mercurial) can be difficult until you’re well versed with it. And if you hg import a URL that doesn’t match up with...

Regain Disk Space from Homebrew

21.5.2018
One of my favorite utilities is Homebrew, the shell utility for installing and upgrading other utilities — it’s a lazy developer’s dream. Dreams can easily turn to nightmares, however, and I recently learned that Homebrew caches older versions of installed packages, leading...

Get a React Component by DOM Node

15.5.2018
Retrieving a React component’s DOM node is fairly simple from within the component itself, but what if you want to work backward: retrieve a component’s instance by DOM node? This is a task that the old Dojo Toolkit’s Dijit framework allowed with the dojo.byId method, so it made...

How to Get a React Component’s Element

14.5.2018
JSX is an amazing pseudo-language for React, and if I’m honest, it’s what brought me to love React so much. Using React without JSX is cumbersome and frustrating, while using JSX is such an easier way to express your code. One drawback of JSX, however, is that it makes accessing...

Vertically Centering with Flexbox

8.5.2018
Vertically centering sibling child contents is a task we’ve long needed on the web but has always seemed way more difficult than it should be. We initially used tables to accomplish the task, then moved on to CSS and JavaScript tricks because table layout was horribly inefficient —...
