🚀 Quick Start (3 Steps)

Step 1: Add to Page Head

<link rel="stylesheet" href="/app.css">
<script src="/auth.js"></script>

Step 2: Add to Page Body (end)

<script src="/components/nav.js"></script>
<script src="/components/footer.js"></script>

Step 3: Protect the Page

<script>
  requireAuth(); // Redirects to login if not authenticated
</script>

That's it! Navigation and footer auto-inject. You're ready to build.

  }
}

Protected API Call

// Before: fetch('/api/tenders')
// After: use fetchWithAuth
const response = await fetchWithAuth('/api/tenders');
const tenders = await response.json();
// Automatically includes: Authorization: Bearer {token}
