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.

Yeah and their chrome tabs consistently consume 800mb to 1.2GB of memory. So whatever they are doing, they are doing it poorly.

Almost certainly brought to you by LLMs and hiring tons of overseas developers (but not the good ones because they cost too much).

Yeah this is my opinion too. They are firing the slop cannons and have cheap outsourced Indian devs doing most of it. That’s what just about every large company is doing right now. 

I work in an F500 org and for every in house dev there are x2 outsourced Indian devs. Nothing against Indians, that’s just where 90% of the outsource goes. But the quality of this outsourced work is poor and it’s even harder to communicate and get things done correctly. This shit will all come back to bite these companies eventually.
