SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Building production-ready Node.js backends can be time-consuming when starting from scratch; this skill provides templates, patterns, and best practices to accelerate development and ensure maintainability.

Core Features & Use Cases

  • Layered architecture with controllers, services, and repositories for clean separation of concerns.
  • Support for Express.js and Fastify with middleware patterns, including authentication, validation, and error handling.
  • Database integration guidance for PostgreSQL and MongoDB, with patterns for data access and transactions.
  • Authentication and authorization using JWT, plus DI container-based dependency management for testability.
  • API design guidance for REST and GraphQL backends, microservices, and real-time applications.
  • Observability and resilience patterns: logging, structured errors, and graceful shutdown.

Quick Start

Create a production-ready Node.js backend skeleton with Express/Fastify, including authentication, error handling, and database integration.

FAQPage Schema
How do I structure a production-ready Node.js backend with Express or Fastify?▼

Structure a production-ready Node.js backend using a layered architecture with controllers, services, and repositories to separate concerns. This pattern supports both Express and Fastify, incorporating middleware for authentication, validation, and error handling.

What's the best way to implement JWT authentication and dependency injection in a Node.js API?▼

Implement JWT authentication and authorization alongside dependency injection using a DI container. This approach manages dependencies for testability while securing request processing across REST APIs, GraphQL servers, and microservices.

How does database integration work for PostgreSQL and MongoDB in a layered backend architecture?▼

Database integration for PostgreSQL and MongoDB uses specific data access patterns within the repository layer. This isolates database transactions and queries from business logic, ensuring clean separation and maintainable data operations.

Can I use this Node.js backend pattern for microservices and real-time applications?▼

Yes, these Node.js backend patterns apply to REST APIs, GraphQL servers, microservices, and real-time applications. The architecture provides scalable request processing, structured logging, and graceful shutdown for resilient services.

Do I need to manually configure structured logging and graceful shutdown for my Node.js server?▼

No, the patterns include observability and resilience features like structured logging, structured errors, and graceful shutdown. These are built into the backend skeleton to ensure robust request processing and reliable application termination.
