Workers Remote-procedure call (RPC)
Implements a JavaScript-native remote procedure call system to allow Workers and Durable Objects to call methods on each other via Service Bindings.
When To Use
Use when you need to enable one Cloudflare Worker or Durable Object to invoke methods on another Worker within the same account using a native JavaScript syntax.

What This Skill Covers
- To use RPC, define a compatibility date of 2024-04-03 or higher, or include rpc in your compatibility flags.
- Main sections:
Tags,Example,All calls are asynchronous,Structured clonable types, and more,Functions.
Workflow
- Open the most relevant file under
docs/for the exact documented workflow and wording. - Open
schemas/files for exact structured contracts. - Open
examples/files for concrete requests, commands, snippets, and manifests. - Do not add behavior or configuration that is not present in the attached source files.
