Can I use this for both Express and Fastify?

Absolutely. The skill provides specific setups and best practices for both minimalist Express applications and high-performance Fastify servers.

Is authentication included in these patterns?

Yes, it provides ready-to-use middleware patterns for JWT-based authentication and flexible role-based authorization (RBAC).

Does this skill support TypeScript?

Yes, all patterns and examples are fully implemented in TypeScript to ensure type safety, better IDE support, and modern development practices.

What architectural pattern does this skill use?

It promotes a Layered Architecture (Controller-Service-Repository) which separates concerns between HTTP handling, business logic, and data access for better maintainability.

API Development

Builds scalable, production-ready Node.js backend services using Express, Fastify, and professional architectural patterns.

About

This skill provides comprehensive guidance and boilerplate for developing robust Node.js backends using modern frameworks like Express and Fastify. It implements enterprise-grade patterns such as layered architecture (Controller-Service-Repository), dependency injection, and secure middleware for authentication and Zod-based validation. Whether you are building REST APIs, GraphQL servers, or microservices, this skill ensures your backend is maintainable, type-safe, and follows industry best practices for data access and error handling.

Key Features

Layered architecture templates (Controllers, Services, Repositories)
Framework support for both Express.js and high-performance Fastify
Standardized Dependency Injection (DI) container implementation
Secure middleware for JWT authentication and role-based access control
Type-safe schema validation using Zod and TypeScript
23,194 GitHub stars

Use Cases

Bootstrapping a new REST API with a clean, modular structure
Implementing standardized error handling and database integration patterns
Migrating a monolithic backend to a scalable microservices architecture
