const store = createStore(reducer, {
    userInfo: {
        isLogged: false,
        items: localStorage.getItem("@items") || []
    }
})

local storage is not defined in next js because it renders in server side to implement your Redux use this boiler Plate by Next js.

Redux Persist example

This example shows how to integrate Redux with the power of Redux Persist in Next.js.

With the advantage of having a global state for your app using redux. You'll also require some of your state values to be available offline. There comes redux-persist using which you can persist your states in browser's local storage. While there are various ways of persisting your states which you can always find in there documentation. This is an example of how you can integrate redux-persist with redux along with Next.js's universal rendering approach.
