How to Integrate Auth0 & Next.js
User authentication is an essential part of web applications, and integrating Auth0 with Next.js can provide a secure and seamless authentication experience for your users. In this article, we will discuss how to integrate Auth0 with Next.js for user authentication.
Step 1: Set up Auth0 account
The first step is to sign up for an Auth0 account and create a new application. Once you have created a new application, you will be provided with a client ID and client secret that you will need to integrate with your Next.js application.
Step 2: Install Auth0 SDK
In your Next.js project, install the Auth0 SDK using npm or yarn:
npm install @auth0/nextjs-auth0
This SDK will help you integrate Auth0 with your Next.js application and handle user authentication.
Step 3: Add authentication to Next.js pages
To add authentication to your Next.js pages, you will need to create an API route for handling authentication and use the `withPageAuthRequired` higher order component to protect your pages:
import { withPageAuthRequired } from '@auth0/nextjs-auth0';
function Profile() {
return (
<div>
<h1>Welcome, {user.name}!</h1>
</div>
);
}
export default withPageAuthRequired(Profile);
Step 4: Secure API routes
If you have API routes in your Next.js application that require authentication, you can use the `withApiAuthRequired` higher order function to secure those routes:
import { withApiAuthRequired } from '@auth0/nextjs-auth0';
export default withApiAuthRequired(async function me(req, res) {
return res.status(200).json({ user: req.user });
});
Step 5: Handle authentication in the frontend
Finally, you can use the Auth0 SDK to handle login, logout, and user information in your Next.js frontend:
import { useUser } from '@auth0/nextjs-auth0';
export default function Header() {
const { user, error, isLoading } = useUser();
if (isLoading) return <p>Loading...</p>;
if (error) return <p>Error: {error}</p>;
if (user) return <p>Hello, {user.name}</p>;
return (
<div>
<a href="/api/login">Login</a>
<a href="/api/logout">Logout</a>
</div>
);
}
By following these steps, you can easily integrate Auth0 with Next.js for user authentication. This will allow you to provide a secure and seamless authentication experience for your users while building your Next.js application.
node -e "console.log(crypto.randomBytes(32).toString('hex'))"
did exactly as you told on clicking the login i get 500 internal error
what is your nationality?
just some feedback that your keyboard noise is pretty loud
NOTE!!
NOT SO RELATED.
When a Nextjs app has been built(I mean using command like "npm run build" with some environment variables bundled with it).
Those keys kept in Environment Variables can they be found in the bundled code ?
I use auth0 in my server actions, in there I request the accessToken. But when the access token of the user expires, I het an error message saying "Error: The access token expired and a refresh token is not available. The user will need to sign in again.". How to fix this? I tried automatically redirecting the user to the logout endpoint but I was not able to make the user resirect from the server action since it runs on the server and not the client.
Was excited to see this tutorial, until you said you're going to use page router. App router is the future! Moving on to find another tutorial…
subscribed bro ! Thank you.I wanted quick information about Auth0 for project I was not part of and your video helped me. hope you have udemy course you are awesome !
thank you, can you please do a tutorial on next auth with the provider "next-auth/providers/duende-identity-server6"
Hey Arpan, you're freaking awesome! I initially found you from your 'React + Express/Node.js' linking-video! Super cohesive and clear! That said, I was wondering if you could make a video where you integrated Express with NextJS, as I can't seem to find any in-depth youtube videos (or any, in general) on that topic? Thanks!
Hey mister, great tutorial. I am having problems with this. I can properly log in but the access token generated is not a correct JWT. It has signature error. Can you make a tutorial showing how to get the proper JWT to save on local storage? Many thanks!
Watching your videos makes me feel motivated to do something productive in my life and not sleep all day.
Hey thanks man, this was a great simplified tutorial. Appreciate it.
