Do this a few times a day and it starts to eat into your focus. The problem is not that these tools are bad. It is the constant context switch. Your routes live in your codebase, but your tests live somewhere else, usually behind a lo...

LinkedIn frontend switches to React.js

LinkedIn is using React.js these days, but what’s interesting is the CSS side of things too. They seem to have gone down a fairly “in-house atomic CSS” direction, somewhat similar in spirit to tools like StyleX or Linaria. It’s kind of funny looking at LinkedIn’s frontend history: Ember.js: LinkedIn was one of the biggest adopters of Ember. React.js: They’ve since moved heavily toward React. Lin...
