Recaps: TKDodo: React 19 and Suspense - A Drama in 3 Acts , and also How React 19 (Almost) Made the Internet Slower
Joe Savona “We'll hold the 19 release”
Previously, per Andrew: React 19 was ready to release
What does the React team want for data fetching?
Seb: “We never released official Suspense on the client, we did RSCs instead” and “Some people got the render-as-you-fetch memo. Some people chose to ignore it.”
Andrew: “the community shouldn’t think ‘we bullied React into changing fetching strategies”.
Related: how do we communicate with the React team?
Tanner Linsley: “I feel there needs to be a permanent React + community working group”
Joe Savona: “we’re working on ideas to get feedback earlier and more users trying canaries”
