Workers

Workers is a serverless execution environment that runs Cloudflare module Workers on this platform. One ocd process supervises one pinned workerd child on the node. The platform does not provide a global edge, workers.dev, or a Cloudflare dashboard.

With Workers you can:

• Deploy a module Worker (export default { fetch }) with project-local Wrangler
• Bind KV, R2, D1, Durable Objects, Queues, Workflows, and other Workers
• Schedule scheduled() with UTC cron expressions
• Serve Static Assets from the same immutable deployment

export default {
  fetch(request: Request, env: Env): Response {
    return Response.json({
      message: env.GREETING,
      pathname: new URL(request.url).pathname,
    });
  },
} satisfies ExportedHandler<Env>;

The sample in this repository is examples/hello-worker/. Deploy it against a running ocd (default origin http://127.0.0.1:8787):

cd examples/hello-worker
ocd wrangler deploy --env dev
