Auth Client (Next.js + Tailwind + MUI + NextAuth + Axios)

Providers

• Credentials
• Google

API base URL

• NEXT_PUBLIC_BASE_API=http://localhost:5001/api/v1

Setup

1. Install dependencies:

   npm install

2. Create env file:

   cp .env.local.example .env.local

3. Run dev server:

   npm run dev

Notes

• Credentials provider posts to /auth/login on your configured base API.
• NextAuth endpoint is /api/auth/[...nextauth].
• GOOGLE_CLIENT_SECRET must be the OAuth Client Secret from Google Cloud Console credentials, not an access token (tokens often start with ya29.).
• Social login flow (Google):
  • After OAuth callback, frontend exchanges Google tokens with backend via:
  • AUTH_SOCIAL_GOOGLE_ENDPOINT (default: /auth/oauth/google)
  • Backend should return app user + app access token in one of these shapes: { token, data }, { accessToken, user }, or equivalent.
