Nestjs

This gets you up and running with NestJS and Drizzle ORM using the full controller-service-repository pattern. It covers the essentials: CRUD modules, JWT guards, database transactions, DTO validation with class-validator, and unit testing with mocked dependencies. The workflow is straightforward: define your schema, generate migrations with drizzle-kit, verify the SQL before running them, then build your modules. The examples are complete enough to copy and adapt, showing real patterns like transaction handling and guard implementation. One thing to watch: the warnings about keeping transactions short and avoiding circular dependencies are worth heeding early, not after you hit issues in production.
