About this skill

What it does

This skill assists in building secure and scalable integrations with Supabase, a popular open-source database platform. It provides guidance on various aspects of Supabase development including database schema design, implementing Row Level Security (RLS) policies, managing authentication, utilizing Edge Functions, and leveraging real-time features. The skill emphasizes security best practices and type safety throughout the development process.

When to use it

  • Designing a new Supabase database schema for an application.
  • Implementing Row Level Security (RLS) policies to control data access.
  • Generating TypeScript types based on your Supabase schema.
  • Optimizing query performance by creating indexes and implementing pagination.
  • Troubleshooting authentication or real-time feature integration within a Supabase project.

Key capabilities

  • Database Schema Design: Creating tables, triggers, foreign keys, and relationships.
  • Row Level Security (RLS): Defining policies to control data access based on user roles.
  • Type Safety: Generating TypeScript types from the database schema for use in applications.
  • Performance Optimization: Creating indexes, implementing pagination, and using select() to limit returned fields.
  • Authentication Management: Guidance on secure key usage (anon key, service role key).

Example prompts

  • "Generate a SQL query to create a table named 'items' with columns for id, created_at, updated_at, user_id, title, description and status."
  • "Create an RLS policy that allows users to only read their own items in the 'items' table."
  • "What is the best way to implement pagination when querying a large dataset in Supabase?"

Tips & gotchas

  • Always enable Row Level Security (RLS) on tables containing user data.
  • Use service role keys only within secure server contexts, and anon keys for client-side operations.
  • Keep generated TypeScript types synchronized with changes to your database schema.
