## 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`](https://next-auth-example.vercel.app)
Go to [next-auth.js.org](https://next-auth.js.org) for more information and documentation.
## 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](https://jwt.io/introduction) 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: [next-auth.js.org/adapters/overview](https://next-auth.js.org/adapters/overview)
### 3. Configure Authentication Providers
1. Review and update options in `pages/api/auth/[...nextauth].js` 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://next-auth.js.org/configuration/providers/oauth
3. 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
