Cloudflare Assets

Rules

1. Configure static assets in wrangler.jsonc with an assets block that sets both binding and directory.
2. Serve static files from the Worker by returning env.ASSETS.fetch(request) inside fetch.
3. Keep the binding name consistent across config and code (for example ASSETS in both places).

Example 1: wrangler.jsonc

{
  "$schema": "node_modules/wrangler/config-schema.json",
  "name": "my-worker",
  "main": "src/index.ts",
  "compatibility_date": "2026-02-24",
  "assets": {
    "binding": "ASSETS",
    "directory": "./public"
  }
}

Example 2: Minimal Worker

export default {
  async fetch(request, env, ctx) {
    return env.ASSETS.fetch(request);
  },
};
