🧩 ORGANIZATION IN LOVABLE
Lovable separates the app into three clear levels 👇
🧱 COMPONENTS
🔹 Reusable UI blocks
🔹 Used multiple times\
🔹 Do not represent URLs
📌 Examples:
📄 PAGES
🔹 Represent real URLs
🔹 Are complete views
🔹 Users can access them directly
📌 Examples:
- 🏠 Home
- 🔐 Login
- ❓ Not Found
- 🎨 Style Guide
🗺️ ROUTES
🔹 Connect URL ➝ Page
🔹 Control navigation
🔹 Defined in app.tsx
📌 They allow you to:
✔️ Define the default route
✔️ Create protected routes
✔️ Handle 404 errors
⚙️ WHAT IS CONFIGURED IN app.tsx?
📍 Main route map
It defines:
🔗 Which URL goes to each page
🏁 Initial route
🔒 Pages that require login
❌ What to show when a route does not exist
