SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps you manage and optimize your Supabase database, ensuring robust security, efficient data handling, and smooth deployment processes.

Core Features & Use Cases

  • Row Level Security (RLS): Design and implement granular access control policies.
  • Database Migrations: Manage schema changes and version control for your database.
  • Schema Design & Optimization: Create efficient database structures and tune query performance.
  • Auth Integration: Seamlessly integrate user authentication with your database logic.
  • Use Case: You need to implement strict Row Level Security policies to ensure users can only access their own data in a 'posts' table, and you need to create a migration script to add this policy and an index for performance.

Quick Start

Use the supabase-admin skill to create an RLS policy that allows users to only read their own posts.

FAQPage Schema
How do I implement Row Level Security policies in Supabase to restrict users to their own data?▼

Row Level Security (RLS) policies in Supabase restrict data access by leveraging auth.uid() and auth.jwt() functions within PostgreSQL to enforce granular, per-user access control on database tables.

What is the best way to manage database migrations and schema changes in Supabase?▼

Database migrations in Supabase manage schema changes and version control through structured scripts, ensuring smooth deployment processes and optimal database structure updates in production environments.

How does auth.jwt() integration work with PostgreSQL for secure data access control?▼

Auth.jwt() integration works by evaluating JSON Web Token claims directly within PostgreSQL RLS policies, enabling secure, token-based data access control without separate application-layer authentication checks.

Can I optimize PostgreSQL schema design and query performance directly within Supabase?▼

Yes, you can optimize PostgreSQL schema design and tune query performance in Supabase by creating efficient database structures and adding targeted indexes alongside RLS policies during migration.

Why are my Supabase RLS policies not working as expected for user authentication?▼

Supabase RLS policies may fail if auth.uid() returns null for unauthenticated requests or if PostgreSQL policies lack proper schema permissions, requiring careful policy design and integration testing.
