NextAuth.js is a complete open source authentication solution.
This is an example application to demonstrate how to use NextAuth.js with Solana Wallet Adapter as the Solana sign in option.
Bootstrapped with next-auth-example repository, an adaptation of siwe.
The deployed version can be found at solana-next-auth.vercel.app
git clone https://github.com/Blocksmith-Labs/solana-next-auth.git
cd solana-next-auth
npm install
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:
-
Review and update options in
pages/api/auth/[...nextauth].jsas needed. -
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
- You can also choose to specify an SMTP server for passwordless sign in via email.
