I was on the fence about RSC.
I could see the new abilities it unlocked. But I was wary of the added complexity, and I felt like it wasn’t solving the problems that originally brought me to React.
Seeing Parcel’s low level RSC APIs (and now @vitejs/plugin-rsc) changed my mind.

Happy to announce Parcel v2.14, now with support for React Server Components! 🥳
RSCs can be integrated into client-rendered apps, server rendered, or statically rendered at build time.
Also: rust MDX compiler, create-parcel CLI, new error overlay, and native import maps.

ALT Screenshot of code sample: $ parcel server.tsx // server.tsx import express from 'express'; import {renderRequest} from '@parcel/rsc/node'; import {Page} from './Page'; const app = express(); app.get('/', async (req, res) => { await renderRequest(req, res, <Page />); }); app.listen(3000); // Page.tsx "use server-entry"; export function Page() { return ( <html> <body> <h1>Hello world!</h1> <Client /> </body> </html> ); }

“takes a while to get something in the app and approved by the app store”
Apps should iterate just as fast as websites. Use Expo to share React code and push out changes to all users instantly with OTA updates.
