SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires drizzle-orm, nestjs, class-validator, class-transformer, @nestjs/swagger, @nestjs/graphql, @nestjs/throttler, cache-manager, redis, graphql-subscriptions, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides best practices and reusable patterns for designing robust REST and GraphQL APIs with NestJS, addressing complexity and maintainability challenges.

Core Features & Use Cases

  • Endpoint Design: Establishes consistent resource naming, response patterns, and bulk operations.
  • Pagination & Filtering: Implements cursor and offset pagination, supporting complex search queries.
  • Validation & DTOs: Defines nested, partial, and typed DTOs for request validation and response serialization.
  • Error Handling: Centralized exception filters and domain-specific exceptions for reliable error responses.
  • Caching & Invalidation: Uses interceptors and Redis for efficient data caching and cache invalidation strategies.
  • Versioning & Rate Limiting: Supports URI and header-based versioning, with customizable rate-limiting guards.
  • File Uploads & Streaming: Handles large file uploads/downloads and streaming responses for efficient I/O.
  • GraphQL Support: Incorporates DataLoader and resolver best practices.
  • OpenAPI Documentation: Automates API docs with decorators and schema references.
  • Best Practices: Promotes reusable, organized code with clear separation of concerns.

Quick Start

FAQPage Schema
How do I implement scalable REST and GraphQL APIs using NestJS?▼

Scalable NestJS APIs require consistent endpoint design, DTO validation, centralized error handling, and caching interceptors. This approach ensures maintainability and production-grade reliability for complex REST and GraphQL applications.

What is the best way to handle pagination and filtering in a NestJS API?▼

NestJS API pagination and filtering are best handled by implementing both cursor and offset pagination strategies. These patterns support complex search queries and ensure efficient data retrieval across large datasets.

How does Redis caching work with NestJS interceptors for cache invalidation?▼

Redis caching in NestJS uses interceptors to store responses and apply cache invalidation strategies. This mechanism reduces database load and improves response times for frequently accessed API resources.

Can I use class-validator and class-transformer for nested DTO validation in NestJS?▼

class-validator and class-transformer are used to define nested, partial, and typed DTOs for NestJS request validation. They ensure strict data serialization and deserialization across API endpoints.

Does NestJS support URI and header-based API versioning with rate limiting?▼

NestJS supports both URI and header-based API versioning alongside customizable rate-limiting guards. These features use the @nestjs/throttler package to control traffic and manage API evolution.

How do I automate OpenAPI documentation for a NestJS API?▼

Automating OpenAPI documentation in NestJS uses @nestjs/swagger decorators and schema references. This process generates consistent API docs directly from your endpoint definitions and DTO structures.
