Access cookies in NextJS from server side

If you want to set an authentication system like jwt, then you have to store your token inside the client(browser). You store them either in localStorage or as a cookie. But when you perform any kind of server-side operation, then you don't have access to the client. So you can't access the cookies from the server-side. Then what is the solution?

The solution.

import { GetServerSideProps } from 'next'

export const getServerSideProps: GetServerSideProps = async (ctx) => {
    const { req, res } = ctx

    const {cookies} = req

    return { props: {  } }
}
Enter fullscreen mode Exit fullscreen mode

I have created a YouTube video about this. You can check that out. If you like this video, please like and subscribe to my channel.

You can access the cookies from the request object inside the getServerSideProps data fetching method. You can learn about data fetching methods of nextjs from here .

getServerSideProps method takes context as a parameter. A context is a giant object. Request and Response object is inside the context object.

const { req, res } = ctx
Enter fullscreen mode Exit fullscreen mode

In the request object you'll find a cookies object.

const { cookies } = req
Enter fullscreen mode Exit fullscreen mode

All your cookies will be inside the cookies object.

So that's it for this blog.
