NextAuth.js Example App

Open Source. Full Stack. Own Your Data.

Overview

NextAuth.js is a complete open source authentication solution.

This is an example application that shows how next-auth is applied to a basic Next.js app.

The deployed version can be found at next-auth-example.vercel.app

About NextAuth.js

NextAuth.js is an easy to implement, full-stack (client/server) open source authentication library originally designed for Next.js and Serverless. Our goal is to support even more frameworks in the future.

Go to next-auth.js.org for more information and documentation.

NextAuth.js is not officially associated with Vercel or Next.js.

Getting Started

1. Clone the repository and install dependencies

git clone https://github.com/nextauthjs/next-auth-example.git
cd next-auth-example
npm install

2. Configure your local environment

Copy the .env.local.example file in this directory to .env.local (which will be ignored by Git):

cp .env.local.example .env.local

Add details for one or more providers (e.g. Google, Twitter, GitHub, Email, etc).

Database

A database is needed to persist user accounts and to support email sign in. However, you can still use NextAuth.js for authentication without a database by using OAuth for authentication. If you do not specify a database, JSON Web Tokens will be enabled by default.

You can skip configuring a database and come back to it later if you want.

For more information about setting up a database, please check out the following links:

• Docs: authjs.dev/reference/core/adapters

3. Configure Authentication Providers

1. Review and update options in auth.ts as needed.

2. When setting up OAuth, in the developer admin page for each of your OAuth services, you should configure the callback URL to use a callback path of {server}/api/auth/callback/{provider}.

e.g. For Google OAuth you would use: http://localhost:3000/api/auth/callback/google

A list of configured providers and their callback URLs is available from the endpoint api/auth/providers. You can find more information at https://authjs.dev/getting-started/providers/oauth-tutorial

1. You can also choose to specify an SMTP server for passwordless sign in via email.

4. Start the application

To run your site locally, use:

npm run dev

To run it in production mode, use:

npm run build
npm run start

5. Preparing for Production

Follow the Deployment documentation
