Hello World - Cloudflare Workers

A minimal Rivet Actor counter running on Cloudflare Workers with the WebAssembly runtime.

Getting Started

git clone https://github.com/rivet-dev/rivet.git
cd rivet/examples/hello-world-cloudflare-workers
npm install
npm run dev

rivet dev runs a local Rivet engine and spawns wrangler dev for you.

Implementation

The Worker exports createHandler from @rivetkit/cloudflare-workers, which wires the WebAssembly runtime and serves the Rivet handler. No configuration is required in local dev: the engine endpoint defaults to http://localhost:6420. To target a remote engine in production, set RIVET_ENDPOINT as a Worker variable or secret.

• Worker entry (src/index.ts): Counter actor and createHandler.
