I added parallel and recursive route rendering to Twofold, which kind of blew my mind. It's the first time I've used a React pattern that specifically takes advantage of the two phase server/client render. Wrote about it here: twofoldframework.com/blog/paralle...

New blog post: Composable streaming with Suspense One of my favorite patterns lately has been using Suspense to stream in lazily loaded content. It's perfect for dynamic dropdown menu options. twofoldframework.com/blog/composa...

React Router RSC Preview is now available This brings support for all of React's API in a way that is incrementally adoptable by the millions of React Router apps in production today, but also feels great for a greenfield React Router app remix.run/blog/rsc-pre...

If you're running an RSC server how do handle the react-server condition? 1. start node with --conditions=react-server? 2. run node without conditions, but start a worker with the react-server condition? 3. Something else, like a bundle time thing? I've been doing 1, but I'm not sure it's best

I wrote about building toast messages into an app with React Server Components. Really liked how easy it was to use server functions, cookies, and useOptimistic to make this all come together. buildui.com/posts/toast-...

RSC with a form and server action running while JavaScript is turned off

Hey @sebmarkbage.calyptus.eu I have an RSC+MPA question... is there a way to have a <form> that uses a server action directly (so you get $ACTION_ID/REF inputs for MPA), but then after hydration is able to work with client-side code that uses useOptimistic?

Completed this! Ended up releasing it as an open source library: github.com/twofold-rsc/... My first RSC OSS tool, feels good :)

Next.js source is a work of art. I was wondering how they serialize and encrypt action args and found this: github.com/vercel/next.... Of course they use an rsc stream to serialize all the args into a string... and then encrypt!

One of the areas where I've changed my mind recently is with server actions + closures. In the past I believed it was too dangerous to close over variables during render because it creates an implicit client param and therefore devs would be better off being explicit with hidden form inputs. but...

I made a video on useActionState! There's a lot of awesome stuff built into this hook - namely the queuing behavior and the fact that it's made to be used with transitions. Actions are one of the coolest things coming to 19 www.youtube.com/watch?v=p_wn...

Today's uAS thought: There's a beautiful refactor from a client-side only React app to a server backed React app in three steps.
