Responding in Streaming Mode

Last updated: 2024-01-25 11:36:31
    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 => {
