What architectural patterns are included?

The skill primarily implements Layered Architecture (separation of concerns) and Dependency Injection patterns to help you build codebases that are easy to test and maintain as they grow.

Does this skill support TypeScript?

Yes, the skill is fully optimized for TypeScript, providing type-safe implementations for controllers, services, and database repositories to ensure maximum code reliability.

Can I use this for both Express and Fastify?

Absolutely. It includes specific patterns and optimizations for both the minimalist Express.js framework and the high-performance Fastify framework, including schema validation for both.

How does it handle application security?

It implements security best practices including Helmet for header security, CORS configuration, JWT-based authentication middleware, and strict schema-based request validation.

API Development

Architects production-grade Node.js backend services using Express or Fastify with scalable, layered architectural patterns.

About

The Node.js Backend Patterns skill empowers developers to build enterprise-ready server-side applications by providing standardized guidance on modern framework implementation. It focuses on a clean layered architecture—dividing logic into controllers, services, and repositories—to ensure code maintainability and testability. Beyond basic setup, the skill integrates advanced middleware patterns for JWT authentication, Zod-based request validation, dependency injection, and optimized database interactions, making it ideal for transitioning from simple scripts to robust microservices or REST APIs.

Key Features

Standardized dependency injection container for decoupled components
Modular layered architecture (Controller-Service-Repository patterns)
Production-ready security middleware and JWT authentication flows
Type-safe request validation using Zod and Fastify schemas
High-performance Fastify and minimalist Express.js configurations
3 GitHub stars

Use Cases

Establishing a standardized project structure for team-based Node.js development
Implementing secure authentication and authorization systems for microservices
Developing scalable RESTful APIs or GraphQL backends for web and mobile apps
