Nestjs

What it does

The NestJS skill enables AI agents to work with the NestJS framework, a progressive Node.js framework for building efficient and scalable server-side applications. It supports features like modular architecture, dependency injection, and integration with various databases and external services.

When to use it

• You need to build a REST API or microservices-based backend application using TypeScript.
• Your project requires a structured approach with modules, controllers, and services.
• You are looking to integrate third-party libraries like MongoDB, GraphQL, or Redis into your Node.js application.

Key capabilities

• Modular architecture for organizing code
• Built-in support for dependency injection
• Integration with databases (e.g., MongoDB, PostgreSQL)
• REST API development with decorators and routing
• Support for real-time applications using WebSockets

Example prompts

• "Generate a NestJS module for user authentication with JWT."
• "Create a REST API endpoint for retrieving product data from a MongoDB database."
• "Set up a WebSocket server in NestJS to handle real-time notifications."

Tips & gotchas

• Ensure you have Node.js and TypeScript installed before using this skill.
• While NestJS is highly scalable, it may introduce complexity for simple projects—consider if the framework's features are necessary for your use case.
