Return JSON

Return JSON directly from a Worker script, useful for building APIs and middleware.

export default {
  async fetch(request) {
    const data = {
      hello: "world",
    };


    const json = JSON.stringify(data, null, 2);


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

};


const handler: ExportedHandler = {
  async fetch(request: Request) {
    const data = {
      hello: "world",
    };


    const json = JSON.stringify(data, null, 2);


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

};
