Utilize localstorage with Redux and Next.js to initialize the state

Having an issue when attempting to populate the initial state from local storage in order to create a store. I encountered the following error message:

ReferenceError: localStorage is not defined

Here is my store configuration:

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

Answer №1

In Next.js, local storage is not defined due to its server-side rendering nature. To incorporate Redux into your project, you can use the boilerplate provided by Next.js.

Check out this example of Redux Persist

This example demonstrates how Redux can be integrated with Redux Persist in Next.js. By using Redux, you can create a global state for your application and ensure some state values are accessible offline as well. Redux Persist allows you to store your states in the browser's local storage. Although there are different methods available for persisting states, this example showcases the integration of redux-persist with Redux in conjunction with Next.js's universal rendering approach.
