New blog post: Composable streaming with Suspense
I've been using this technique to let components lazily load their data. It's been perfect for dropdowns with dynamic content.
My first AI course is here.
It's the perfect way to go deep into building great AI apps.
We're building a complex, agentic search app from scratch, in 100% TypeScript.
And for the first time, we're running it as an async workshop. I'll be by your side, helping you out.
