Twitter Thread Crash Courses

Chris (@chrisachard) and I (@hexrcs) created a few crash courses in the format of Twitter threads. People seem to love them!

The idea was to reduce complex stuff down to no more than ten 280-character tweets, then couple them with carefully crafted images to illustrate the points. (Chris invented this genius format!)

Here are some of those crash courses!

Hope you enjoy them! (More are coming! :smiley:)

Thanks for sharing Leo I need to make one of these about CSS or something theyโ€™re really valuable!

What did you use to add annotations to the images?

I really like your svelte one as well!


Your GQL thread was a nice summary. Thanks!


A thread on CSS is a great idea, looking forward to it! :smiley:

I mostly used carbon to generate the syntax-highlighted code snippets, pasted in Figma then added annotations by hand. I think I should probably come up with a design system and a component library :rofl: There are definitely better ways to make them! :sweat_smile:

All my images by far are in 2:1 format because this way readers wonโ€™t need to click on them to see the whole pic in the Twitter web app. This limits the freedom a lot and probably isnโ€™t a good idea if you want to show some more lines of code.


Wow! What a great idea and thanks for putting these together. I love the EggHead community always thinking outside the Tweet (see what I did there?) :smile:. Also Thanks for sharing your recipe and for thinking of the user by making your images 2:1. Nice touchโ€ฆ

Keep it up!


Thanks for sharing Leo! This is a really cool resource and ideas. I enjoyed your GraphQL crash course! Iโ€™m considering creating a Twitter thread crash course on CSS Grid. :smile:

Thanks for sharing/creating these. I love the simple ( but not too simple) explanations and diagrams. Distilling the key concepts down to easily digestible nuggets.

Love the format.

Nice! Thanks for sharing this!

I have been wondering about Redux with hooks for a while now. I might have to give it a try one of these days!
