I encountered an issue where useRouter is returning null and router.isready is not functioning properly with nextjs version 13

Question

I encountered an issue where useRouter is returning null and router.isready is not functioning properly with nextjs version 13

After experimenting with Next.js version 13, I encountered an error in my code that I am struggling to resolve. Here is the code snippet:

import { useRouter } from 'next/navigation';

async function getCheckoutInfo() {
    const router = useRouter();
    if (router.isReady) {
        console.log('Router query:', router.query);
    } else {
        console.log('Router is not ready yet')
    }
    
    return 'test';
}


export default async function CheckoutPage() {
    const info = await getCheckoutInfo();

    return(
        <div>
            <h1>Checkout </h1>
            <p>{info}</p>
        </div>
    )
}

Upon encountering the error, the message displayed was:

Unhandled Runtime Error
Error: Cannot read properties of null (reading 'useContext')

Call Stack
Object.useContext
webpack-internal:///(sc_server)/./node_modules/next/dist/compiled/react/cjs/react.shared-subset.development.js (1428:31)
useRouter
webpack-internal:///(sc_server)/./node_modules/next/dist/client/components/navigation.js (91:32)

I suspect that the issue lies with the usage of useRouter as it seems to not be functioning correctly. In previous versions, I utilized useEffect(), which worked fine. However, according to the documentation for Next.js 13, this should no longer be necessary: https://beta.nextjs.org/docs/api-reference/use-router

I appreciate any assistance in solving this mystery.

Answer №1

When using NextJS 13, the router.ready method is no longer available. Instead, you can utilize the following methods:

router.push
router.replace
router.refresh()
router.prefetch
router.back()
router.forward()

If you need to access query values, you can use the hook useSearchParams as shown below:

import { useSearchParams } from 'next/navigation';


export default async function CheckoutPage() {
    const searchParams = useSearchParams();

    return(
        <div>
            <h1>Checkout </h1>
            <p>{searchParams.toString()}</p>
        </div>
    )
}

If you are using the latest version of the App Directory, React Components are divided into two categories: Server and Client Components (you can find more information here https://beta.nextjs.org/docs/rendering/server-and-client-components). By default, they are considered React Server Components.

Components that utilize hooks (such as useRouter, useEffect, use...) fall under the category of Client Components. To designate them as such, you must include the "use client" directive at the beginning of the file (before any imports) (following the convention outlined here https://beta.nextjs.org/docs/rendering/server-and-client-components#client-components). Therefore, your code should look like this:

'use client';

import { useRouter } from 'next/navigation';

//... rest of the code

Make sure to only use useRouter() at the top level of your React function component.

Avoid calling Hooks inside loops, conditions, or nested functions. Stick to using Hooks at the beginning of your React function, before any early returns.

Here's a sample code snippet to help you:

import { useRouter } from 'next/router';

function getCheckoutInfo(router) {
    if (router.isReady) {
        console.log('Router query:', router.query);
    } else {
        console.log('Router is not ready yet')
    }
    
    return 'test';
}

export default function CheckoutPage() {
    const router = useRouter();
    const info = getCheckoutInfo(router);

    return(
        <div>
            <h1>Checkout </h1>
            <p>{info}</p>
