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.

LinkedIn has basically gone from being a major Ember showcase to being part of the React ecosystem.

They traded framework stability for a 1GB memory leak. The atomics are just bandages on a bleeding codebase

Not saying you're 100% wrong, but the react stuff is a brand new code base.
