An alternative of oauth2_proxy implemented with njs scripting language. There is a similar implementation for NGINX Plus, but this can also work on open source NGINX.

1. Edit nginx/js/config.js and fill clientId and clientSecret
   • Create OAuth 2.0 Client ID here
   • Add https://localhost/oauth2/callback to Authorized redirect URIs
2. Run docker-compose up -d
3. Open https://localhost/
4. Login with your gmail account
5. It works!

• You must set cookieSecret on production environment.
• You can implement custom auth-strategy, see nginx/js/handler.js and nginx/js/acl.js.
• You can pass some user profile to backend, see an end of authHandler function.
• Initial implementation uses Google as an OpenID provider. Other providers also can be used.
