2. Production-Ready Drizzle ORM Cursor Rules (.cursorrules & .mdc)

Drizzle ORM schema declaration, relational queries, and migration practices. Save this into .cursor/rules/drizzle.mdc in your project repository.

// Drizzle ORM AI Rules
- Define schemas in separate schema/*.ts files and export through a central index.ts.
- Prefer Drizzle's relational queries (db.query) for nested JSON joins without manual aggregations.
- Run 'drizzle-kit generate' followed by 'drizzle-kit migrate' in deployment pipelines.
- Use prepared statements (db.select()...prepare()) for high-throughput API endpoints.
