Introduction

This video demonstrates how to implement usage-based restrictions for different SaaS subscription tiers using Supabase, PostgreSQL, and database migrations. It covers creating tables, implementing Row Level Security (RLS) policies, utilizing PostgreSQL functions and triggers, and managing schema changes across multiple Supabase instances (production and local development).

Key Takeaways

• Database Migrations for Sync: The video emphasizes using Supabase's CLI to generate and manage PostgreSQL migration files, ensuring consistency between production and local development environments.
• RLS for Security: Row Level Security (RLS) policies are implemented to control data access based on user roles and subscriptions. This ensures that users only see data relevant to their subscription tier.
• PostgreSQL Functions and Triggers for Business Logic: PostgreSQL functions and triggers are used to enforce business rules related to usage limits. These functions check subscription status and usage thresholds before allowing actions like creating new notes.
• One-to-one Relationships: The video demonstrates how to set up one-to-one relationships between tables (e.g., products and rules) to manage subscription tier restrictions effectively.
• Separation of Concerns: The video advocates separating security logic (using RLS) from business logic (using PostgreSQL functions and triggers) for improved maintainability and clarity.
