I am working on a nextjs website for a tezos project. In the local environment, it's working fine. But I get an error while deploying it.


ReferenceError: localStorage is not defined

It's due to the Airgap package it seems. I know that the error is because next uses server-side rendering and due to this error is occurring.

But I don't know how to fix it. Can anyone tell me how to fix it?

  • localStorage doesn't exist on the server so need to assure that that part of the code can only run client side. Can you provide a repro? Jun 5 at 15:28

The reason for this error is that in the nextjs application, the Airgap package code gets executed on the server side; hence, the localStorage was not accessible.

The solution here is to create an instance of the package on the client side.

You can find a complete solution to this by the Plenty Networks team here https://github.com/Plenty-network/plenty-network-frontend/blob/main/src/common/walletconnect.ts


Also make sure it only runs on browser/client side, there's a few posts about it on reddit/stackoverflow, you can check for window

const ISSERVER = typeof window === "undefined";

if(!ISSERVER) ....

or just make the component run client-side only with:

"use client";
