Cloudflare Worker

Deploy a comprehensive Cloudflare Worker with Durable Objects, Workflows, RPC, R2, Queues, and AI Search

Cloudflare Worker Example

This example demonstrates a complete Cloudflare Worker application with multiple advanced features including Durable Objects, Workflows, Service Bindings (RPC), R2 Buckets, Queues, and AI Search.

Features

• Worker: Main HTTP handler with multiple bindings
• Durable Objects: Stateful objects with SQLite storage
• Workflows: OFAC workflow processing
• RPC Worker: Service-to-service communication
• R2 Bucket: Object storage
• Queue: Message queue for async processing
• AI Search: Vector search on R2 bucket contents

Project Setup

Key Features Explained

Durable Objects with SQLite

The example uses Durable Objects with SQLite storage enabled:

DO: DurableObjectNamespace<HelloWorldDO>("HelloWorldDO", {
  className: "HelloWorldDO",
  sqlite: true,
})

Queue Event Source

The worker is configured to process queue messages:

eventSources: [
  {
    queue,
    settings: {
      maxWaitTimeMs: 1000,
      batchSize: 10,
    },
  },
]

AI Search on R2

Vector search is enabled on the R2 bucket:

export const rag = await AiSearch("rag", {
  source: bucket,
});

RPC Service Binding

Workers can communicate via typed RPC:

export const rpc = await Worker("rpc", {
  entrypoint: "./src/rpc.ts",
  rpc: type<MyRPC>,
});
