SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides guidance and code examples for building robust, scalable, and maintainable backend systems, addressing common challenges in API design, database management, and server-side logic.

Core Features & Use Cases

  • API Design: Learn RESTful and GraphQL principles, repository, service, and middleware patterns.
  • Database Optimization: Understand indexing, N+1 query prevention, and transaction management.
  • Caching: Implement Redis caching and cache-aside strategies.
  • Error Handling: Utilize centralized error handlers and retry mechanisms.
  • Auth & AuthZ: Implement JWT validation and role-based access control.
  • Rate Limiting: Apply in-memory rate limiting.
  • Background Jobs: Set up simple job queues for asynchronous processing.
  • Logging: Implement structured logging for better observability.

Quick Start

Use the backend-patterns skill to generate an example of the repository pattern for a Node.js API.

Frequently Asked Questions about backend-patterns

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement the repository pattern in a Node.js API?▼

You can implement the repository pattern in a Node.js Express API by separating data access logic into repository classes. This Skill provides code examples for structuring repositories alongside service layer and middleware patterns.

What's the best way to prevent N+1 queries and optimize database indexing in Node.js?▼

Database optimization in Node.js involves proper indexing and query batching to prevent N+1 issues. This Skill covers indexing strategies, N+1 query prevention, and transaction management for maintaining scalable backend performance.

How does JWT validation and role-based access control work in Express and Next.js API routes?▼

JWT validation in Express and Next.js API routes verifies tokens to authenticate requests before accessing protected resources. This Skill demonstrates implementing JWT validation combined with role-based authorization to secure backend endpoints.

Can I use Redis caching and cache-aside strategies with Next.js API routes?▼

Redis caching works with Next.js API routes using the cache-aside pattern to reduce database load. This Skill provides implementation guidance for applying cache-aside strategies to improve backend response times and scalability.

Does this backend architecture guidance apply to Next.js API routes or only Express?▼

The backend architecture guidance covers both Next.js API routes and Express implementations. It provides patterns like middleware, service layers, and centralized error handling suitable for either Node.js framework.

How do I set up background jobs and in-memory rate limiting in a Node.js backend?▼

Background jobs in Node.js use simple job queues for asynchronous processing, while in-memory rate limiting restricts API request frequency. This Skill provides implementation patterns for both to maintain backend stability.
