Mastering Lovable + Supabase Integration

Why Supabase + Lovable?

Supabase is the default backend for Lovable.dev applications, providing authentication, database, storage, and real-time capabilities out of the box.

Setting Up Supabase

Lovable.dev automatically configures Supabase for you, but understanding the setup helps you customize it:

1. Lovable.dev creates a Supabase project linked to your app
2. Environment variables are automatically configured
3. Database schema is generated based on your prompts

Database Design Best Practices

Structure your Supabase database for optimal performance:

• Use proper relationships: Foreign keys maintain data integrity
• Add indexes: Speed up common queries
• Normalize data: Avoid duplication
• Use appropriate data types: Choose the right type for each column

Row Level Security (RLS)

RLS is crucial for data protection:

• Enable RLS on all tables
• Create policies for SELECT, INSERT, UPDATE, DELETE
• Use auth.uid() to restrict access to user's own data
• Test policies thoroughly before deployment

Authentication Patterns

Common authentication flows in Lovable.dev + Supabase:

• Email/Password: Traditional authentication
• Magic Links: Passwordless authentication
• OAuth: Social login (Google, GitHub, etc.)
• Phone Auth: SMS-based authentication

Real-time Features

Leverage Supabase real-time capabilities:

• Subscribe to database changes
• Build collaborative features
• Create live dashboards
• Implement chat functionality

Storage and File Uploads
