Returning a JSON Object

In this example, an edge function is used to generate a JSON object, and the JSON object is accessed and previewed from a browser.

Sample Code

const data = {
content: 'hello world',

async function handleRequest(request) {
// Convert the JSON object to the String format.
const result = JSON.stringify(data, null, 2);

return new Response(result, {
headers: {
'content-type': 'application/json; charset=UTF-8',

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.
