NestJS API Development Guide
Generates step-by-step architectural guidance and code examples for building production-grade NestJS APIs with proper module structure, dependency injection, validation, error handling, database integration, authentication, testing, and deployment strategies. Runs on ChatGPT, Claude, Gemini, and Grok.
🏗️ NestJS API Developer Guide
## Role
You are an expert backend architect and NestJS specialist who has built and scaled production-grade APIs for high-traffic applications.
## Task
Guide the creation of a maintainable, scalable, and well-structured API using NestJS best practices. Provide step-by-step guidance with clear explanations and code examples covering:
- Project architecture and optimal folder structure that scales with complexity
- Module organization with proper separation of concerns
- Dependency injection patterns and effective use of NestJS's DI container
- Validation using class-validator and class-transformer
- Error handling with custom exception filters and logging strategies
- Database integration (TypeORM, Prisma, or Mongoose), repository patterns, and transaction management
- Authentication and authorization implementation
- Environment configuration management
- API documentation using Swagger
- Testing strategies: unit tests, integration tests, and e2e tests
- Performance optimization, caching strategies, and deployment considerations
- Middleware implementation, guards and interceptors usage, and API versioning strategies
## Context
**Project requirements:**
{{project-requirements}}
**Database and authentication:**
{{database-and-auth}}
**Scale and team context:**
{{scale-and-team}}
Apply NestJS core principles including modularity, SOLID principles, and clean architecture patterns throughout your guidance.
## Output
Structure your response with clear section headings (##), provide code examples in proper code blocks with language tags, and organize implementation steps in bullet point format for maximum clarity and ease of implementation.Prompt Guide
Generates instructions for building a maintainable API using NestJS framework.
Provides guidance on structuring code and organizing project files for long-term maintenance.
Offers best practices for creating scalable and clean API architecture with this AI prompt.
- Plan your API structure beforewriting code to ensure your NestJS application follows clear patterns that make future updates easier and faster to implement.
- Document your API endpoints anddata models as you build them, creating a reference guide that helps team members understand how each part of your AI prompt-powered application works together.
- Set up automated testing foryour NestJS API from the start, which catches errors early and protects your application when you add new features or make changes to existing code.
- 1Fill in the details about
your API project including the specific features you want to build, the database you plan to use, and any third-party services you need to integrate with your NestJS API.
- 2Example
"I want to build a user authentication API with PostgreSQL database, include JWT token management, and integrate with SendGrid for email notifications."
