Making the Login Button Actually Work

Here's exactly what it takes to turn the fake "Log in" button into a production-ready authentication system.

PRODUCTION READY

What it takes to make Login actually work

The current button only shows an alert. Here's the full technical path to a real, secure login.

1

Backend Authentication

  • User accounts stored in PostgreSQL / Supabase / Firebase
  • Password hashing with bcrypt or Argon2
  • JWT or Session-based auth (httpOnly cookies recommended)
  • OAuth options: Google, Apple, TradingView Connect (future)
2

Frontend Integration

async function login(email, password)
const res = await fetch('/api/auth/login', {
  method: 'POST',
  body: JSON.stringify({email, password})
});
if (res.ok) { window.location = '/dashboard'; }

Replace fakeLogin() with real API call + state management (Zustand / Redux / Context)
