Setting Cookies

Last updated: 2023-09-11 17:49:21
    In this example, cookies are used to count the number of access requests. When a browser accesses the Edge Functions service, the number of access requests is increased by 1.

    Sample Code

    // cookie name
    const COOKIE_NAME = 'count';
    async function handleRequest(request) {
    // collected the current requests' Cookies and resolution into scope
    const cookies = new Cookies(request.headers.get('cookie'));
    const cookieCount = cookies.get(COOKIE_NAME);
    // count increment
    const count = Number(cookieCount && cookieCount.value || 0) + 1;
    // update Cookie's count
    cookies.set(COOKIE_NAME, String(count));
    const response = new Response(`The count is: ${count}`);
    // setting responded cookies
    response.headers.set('Set-Cookie', getSetCookie(cookies.get(COOKIE_NAME)));
    return response;
    // concatenate Set-Cookie
    function getSetCookie(cookie) {
    const cookieArr = [
    const key2name = {
    expires: 'Expires',
    max_age: 'Max-Age',
    domain: 'Domain',
    path: 'Path',
    secure: 'Secure',
    httponly: 'HttpOnly',
    samesite: 'SameSite',
    Object.keys(key2name).forEach(key => {
    if (cookie[key]) {
    return cookieArr.join('; ');
    addEventListener('fetch', (event) => {

    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.
