@hattip/adapter-cloudflare-workers

Hattip adapter for Cloudflare Workers.

Usage

Assuming you have your Hattip handler defined in handler.js, create an entry file like the following and use @hattip/bundler-cloudflare-workers or your favorite bundler to bundle it:

import cloudflareWorkersAdapter from "@hattip/adapter-cloudflare-workers";
import handler from "./handler.js";

export default {
  fetch: cloudflareWorkersAdapter(handler),
};

If you don't need to serve static files, you can import the adapter from @hattip/adapter-cloudflare-workers/no-static instead. You will get an error if you use the default adapter but you don't set up site = { bucket = "<YOUR STATIC FILES DIR>" } in your wrangler.toml.

@hattip/adapter-cloudflare-workers uses the newer modules format instead of the service worker format.

context.platform

export interface CloudflareWorkersPlatformInfo {
  /** Platform name */
  name: "cloudflare-workers";
  /**
   * Bindings for secrets, environment variables, and other resources like
   * KV namespaces etc.
   */
  env: unknown;
  /**
   * Execution context
   */
  context: ExecutionContext;
}

Environment variables

The ctx.env() function only returns bindings with a string value. Such bindings correspond to secrets and environment variables. Other bindings like KV or D1 will return undefined. You should use ctx.platform.env to access them instead.
