Fetch Remote Resources

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

Sample Code

async function handleRequest(request) {
// Fetch a remote resource.
const response = await fetch('https://static.cloudcachetci.com/qcloud/main/scripts/release/common/vendors/jquery-3.2.1.min.js');
return response;
}

addEventListener('fetch', event => {
return event.respondWith(handleRequest(event.request));
});

Sample Preview

In the address bar of the browser, enter a URL that matches a trigger rule of the edge function to preview the effect of the sample code.
