Implementing Google Sign-In Authentication with Next-Auth in Next Js 13.4

Google SignIn Authentication in Next Js 13.4 | Next-Auth

In this article, we will discuss how to implement Google SignIn Authentication in a Next Js 13.4 application using the Next-Auth library.

Next Js is a popular framework for building React applications with server-side rendering, and it provides a robust ecosystem for handling authentication. Next-Auth is a library that simplifies the process of adding authentication to Next Js applications, and it supports various authentication providers, including Google.

To get started with Google SignIn Authentication in Next Js 13.4, you will need to create a new Next Js application or use an existing one. Once you have your Next Js application set up, you can install the Next-Auth library by running the following command:

“`html
npm install next-auth
“`

After installing the Next-Auth library, you can set up Google SignIn Authentication by following these steps:

1. Create a Google Developer Project:
– Go to the Google Developer Console and create a new project.
– Enable the Google SignIn API for your project.

2. Configure OAuth Credentials:
– Create OAuth 2.0 credentials for your project.
– Configure the authorized redirect URI to point to your Next Js application.

3. Set Up Next-Auth Configuration:
– Create a `next-auth` configuration file in your Next Js application.
– Add the `providers` property to the configuration file and specify Google as the authentication provider.

“`html
// next-auth.config.js
import NextAuth from ‘next-auth’;
import GoogleProvider from ‘next-auth/providers/google’;

export default NextAuth({
providers: [
GoogleProvider({
clientId: process.env.GOOGLE_CLIENT_ID,
clientSecret: process.env.GOOGLE_CLIENT_SECRET
})
],
});
“`

4. Add `signin` and `signout` pages:
– Create a `signin` and `signout` page in your Next Js application to handle authentication.

“`html
// pages/api/auth/signin.js
import { signIn } from ‘next-auth/react’;
export default (req, res) => {
signIn(‘google’, { callbackUrl: ‘http://localhost:3000/dashboard’ });
};

// pages/api/auth/signout.js
import { signOut } from ‘next-auth/react’;
export default (req, res) => {
signOut({ callbackUrl: ‘/’ });
};
“`

5. Add Google SignIn Button:
– Add a Google SignIn button to your application’s login page and call the `signin` API endpoint when the button is clicked.

“`html

signIn(‘google’)}>Sign in with Google
“`

By following these steps, you can easily implement Google SignIn Authentication in your Next Js 13.4 application using the Next-Auth library. This allows users to sign in to your application using their Google accounts, providing a seamless and secure authentication experience.
