cookies - How to use getServerSideProps for every pages in next.js?

Question

I have set a cookie with nookies which store the values of all the products selected by user. I want to fetch the cookie in server side using getServerSideProps and pass the value as props. I have to display the value of cookie on all pages.

When I tried getServerSideProps in _app.js. It did not worked and it did not even run the code.

Is there any way to do it?

Answer 1

getServerSideProps does not work in _app.js. see docs.

you could use the older getInitialProps in your custom app component but then the automatic static optimisation is disabled, which is something Next.js bets on heavily.

it might be worth digging into your cookie use case and figure out if you really need to read it on the server side.
