I've done a bunch of Egghead lessons about react and redux in the previous weeks and they were really nice.
This one is weird : git repo is not tagged for each lesson, so I just clone master, run
npm install (twice because it fails on the first time because... npm I guess).
npm run test it fails for some tests because of some TypeError... ok...
npm run dev or
run serve it fails because of some react-color-picket asset... ok...
Anyway I start the video, not even 1 minute to say what we are dealing with. So good luck for me to understand what could be the react-color-picker error above, or the TypeError.
Of course files I got from master branch are not the one displayed in the video. In fact, I guess only reading the code without watching video would do the same trick. Or just go to read documentation about expect, mocha and friends.
It kind of sucks because it seems there are lot of things to be learnt from your lessons, but the way it was built really does not help.
