Backend Development

This one gives Claude a practical reference for building backend systems, covering REST conventions, database schemas with UUID patterns, JWT auth, and caching strategies. You'll want it when designing APIs from scratch or reviewing architecture decisions. The examples are opinionated in a good way: soft deletes, cursor pagination, structured error responses, rate limiting middleware. It's not comprehensive documentation, more like a cheat sheet of sensible defaults. Useful for getting consistent patterns across endpoints without reinventing conventions every time, and the SQL snippets alone save you from looking up index syntax.

RESTful Conventions

GET    /users          # List users
POST   /users          # Create user
GET    /users/:id      # Get user
PUT    /users/:id      # Update user (full)
PATCH  /users/:id      # Update user (partial)
DELETE /users/:id      # Delete user

GET    /users/:id/posts  # List user's posts
POST   /users/:id/posts  # Create post for user

Response Format

  }
}

Error Format

Database Patterns

Schema Design

-- Use UUIDs for public IDs
CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  public_id UUID DEFAULT gen_random_uuid() UNIQUE,
  email VARCHAR(255) UNIQUE NOT NULL,
  created_at TIMESTAMPTZ DEFAULT NOW(),
  updated_at TIMESTAMPTZ DEFAULT NOW()
);

-- Soft deletes
ALTER TABLE users ADD COLUMN deleted_at TIMESTAMPTZ;
