This is a Next.js project bootstrapped with create-next-app.

NextAuth + Keycloak setup

  1. Copy environment variables:
cp .env.example .env.local
  1. Set values in .env.local:
  • NEXTAUTH_SECRET: generate one with openssl rand -base64 32
  • KEYCLOAK_ISSUER: e.g. http://localhost:8080/realms/<your-realm>
  • KEYCLOAK_CLIENT_ID and KEYCLOAK_CLIENT_SECRET: from your Keycloak client
  1. In Keycloak client settings, add callback URL:
  • http://localhost:3000/api/auth/callback/keycloak
  1. Start the app and test sign-in:
npm run dev

Open http://localhost:3000 and click Sign in with Keycloak.
