Return small HTML page

Last reviewed: over 1 year ago

Deliver an HTML page from an HTML string directly inside the Worker script.

If you want to get started quickly, click on the button below.

This creates a repository in your GitHub account and deploys the application to Cloudflare Workers.

export default {
  async fetch(request) {
    const html = `<!DOCTYPE html>
    <body>
      <h1>Hello World</h1>
      <p>This markup was generated by a Cloudflare Worker.</p>
    </body>`;

    return new Response(html, {
      headers: {
        "content-type": "text/html;charset=UTF-8",
      },
    });
  },
};

Run Worker in Playground

export default {
  async fetch(request): Promise<Response> {
    const html = `<!DOCTYPE html>
    <body>
      <h1>Hello World</h1>
      <p>This markup was generated by a Cloudflare Worker.</p>
    </body>`;

    return new Response(html, {
      headers: {
        "content-type": "text/html;charset=UTF-8",
      },
    });
  },
} satisfies ExportedHandler;

from workers import Response

def on_fetch(request):
    html = """<!DOCTYPE html>
    <body>
      <h1>Hello World</h1>
      <p>This markup was generated by a Cloudflare Worker.</p>
    </body>"""

    headers = {"content-type": "text/html;charset=UTF-8"}
    return Response(html, headers=headers)

use worker::*;

#[event(fetch)]
