Nestjs Best Practices

The NestJS Best Practices skill empowers AI agents to generate production-ready backend code by enforcing architectural patterns, dependency injection, and modular design principles specific to the NestJS framework. It ensures that generated solutions adhere to industry standards for scalability and maintainability, reducing technical debt from the outset.

When to use it

• Generating new modules or controllers that strictly follow the decorator-based architecture of NestJS.
• Refactoring legacy codebases to incorporate dependency injection and service separation.
• Creating database interactions that utilize TypeORM or Prisma within a repository pattern.
• Building middleware and guards for robust authentication and authorization flows.

Key capabilities

• Enforces strict adherence to the core NestJS architectural patterns (Modules, Providers, Controllers).
• Implements proper dependency injection strategies to decouple components.
• Generates type-safe interfaces using TypeScript best practices.
• Structures error handling and logging mechanisms consistent with enterprise applications.

Example prompts

• "Create a new user module with a controller, service, and repository following NestJS best practices."
• "Refactor this existing function to use dependency injection and adhere to the single responsibility principle in NestJS."
• "Generate a custom guard for JWT authentication that integrates seamlessly with the NestJS HTTP adapter."

Tips & gotchas

Ensure your AI agent has access to the latest NestJS documentation or configuration files, as framework versions evolve rapidly. While the skill promotes modularity, avoid over-engineering simple scripts by forcing complex module structures where they aren't necessary.
