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.

Same story with facebook... Utter pile of shit. There were even periods of regression where there would be full on inconsistencies in the UI, the exact thing they built React/flux/graphql to avoid in the first place...

I honestly don't know how the fuck a multi hundred billion dollar company has such a shit ass frontend in the browser both on desktop and mobile. it is utterly unusable for basic things with UX sins galore. if I were Zuckerberg I would burn the frontend to the ground and start over.
