Live demo of RPCs and entrypoints ✅

JavaScript frameworks provide their own Node.js local dev servers.

The Workers runtime provides built-in APIs to D1, R2, KV and more.

You just want local dev to work like prod.

We figured it out — with framework maintainers help. Here's how we did it:

Ok, this is the best Cloudflare announcement this week.
Cloudflare, hit me up once you open the marketplace sign-ups. You know I got some neat ideas.

Cloudflare Workers now features a built-in RPC (Remote Procedure Call) system for use in Worker-to-Worker and Worker-to-Durable Object communication, with absolutely minimal boilerplate. cfl.re/3U5qPoM #DeveloperWeek

Brendan Coll While I'm at it, thanks Glen Maddern Michael Hart James M Snell and Brendan Irvine-Broque for tons of feedback and spirited design discussions, and Milan (mellowyarker on GitHub; twitter handle unknown) for kicking off the initial implementation that got me going...

JavaScript-native RPC.

- JS language standards only, no special protocols
- define a public class method, call it from another Worker
- each named export in your Worker can provide its own RPC interface
- works with Durable Objects too
