Like any other header, a cookie is also a header that web apps use to store essential information. If you want to clear a cookie from server-side in Next.js (which uses node.js under the hood) you can simply use response's <code>setHeader</code> method like so:
<pre><code class="lang-js">res.setHeader('Set-Cookie', 'some-cookie=someValue; Max-Age=0');
</code></pre>
The important part is setting <code>Max-Age=0</code>, which will make the browser delete that cookie immediately.

PS: This will work for other frameworks and languages too, syntax might be different but Headers work in the same way across all browsers
