NextAuth.js Example App
Open Source. Full Stack. Own Your Data.
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
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.
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).
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:
3. Configure Authentication Providers
Review and update options in
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
e.g. For Google OAuth you would use:
A list of configured providers and their callback URLs is available from the endpoint
/api/auth/providers. You can find more information at https://next-auth.js.org/configuration/providers/oauth
- 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
