From Facebook Engineering Blog:
Tons of great nuggets in here, and a lot that I can relate to in what’s we’ve been up to at my job.
Facebook reduced their CSS by 80%, added code splitting and added code budgets to help deliver what’s needed only when it’s needed. They also moved to GraphQL to modernize their data fetching.
It’s a shame Facebook makes products that are so terrible for society, because they really do build world-class software.
