SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Backend teams need consistent, documented server-side practices to design scalable APIs without reinventing repository, caching, or auth logic each time.

Core Features & Use Cases

  • API Design and Layers: outlines RESTful structures, repository abstraction, service layers, and middleware for authentication and request pipelines.
  • Database and Caching Playbooks: covers query optimization, N+1 prevention, transactions, Redis caching, and the cache-aside pattern for low-latency reads.
  • Reliability and Observability: summarizes centralized error handling, exponential backoff retries, authorization gating, rate limiting, job queues, and structured logging for monitoring.
  • Use Case: When planning a Node.js or Next.js backend, leverage these patterns to align architecture reviews, API design, and operational safeguards across your team.

Quick Start

Use the backend-patterns skill to review your Node.js API design and identify where to apply repository, caching, auth, and monitoring patterns.

FAQPage Schema
How do I structure a Node.js backend with repository and service layers?

Structure a Node.js backend by applying repository abstraction for data access and service layers for business logic. This pattern separates data persistence from API route handling to align server-side teams and ensure scalable architecture.

What is the cache-aside pattern and how does it optimize backend caching strategies?

The cache-aside pattern optimizes backend caching by loading data into cache only when requested. Implementing this with Redis enables low-latency reads while preventing direct database query bottlenecks in Node.js applications.

How do I implement centralized error handling and middleware in Express?

Centralized error handling in Express uses dedicated middleware to catch and process API errors uniformly. This approach secures error responses and standardizes request pipelines across your server-side architecture.

Does this backend patterns guidance work with Next.js API routes?

Yes, the backend patterns guidance works with Next.js API routes. You can apply repository, caching, authorization, and monitoring patterns directly to Next.js backend implementations alongside standard Node.js and Express environments.

What's the best way to prevent N+1 query issues in backend API design?

Prevent N+1 query issues by applying repository abstraction and query optimization patterns. Structuring database access through service layers ensures transactions and data fetching are batched efficiently for scalable APIs.
