Responding in Streaming Mode

Last updated: 2023-02-13 16:11:01

    In this example, the Fetch API is called to fetch a remote jQuery.js resource, and the resource is sent to a client in streaming mode in response to a request from the client.

    Sample Code

    async function handleRequest(request) {
      const response = await fetch('https://static.cloudcachetci.com/qcloud/main/scripts/release/common/vendors/jquery-3.2.1.min.js');
      if (response.status !== 200) {
        return response;
      // Generate readable streams and writeable streams.
      const { readable, writable } = new TransformStream();
      // Respond to the client in streaming mode.
      return new Response(readable, response);
    addEventListener('fetch', event => {
