nodejs-backend-patterns

To structure a production-ready Node.js backend, implement a layered architecture with dependency injection. This Skill provides patterns for Express.js and Fastify to ensure your API routing, middleware, and data handling remain scalable and maintainable.

The best way to implement global error handling in a Node.js API is by using custom error classes alongside a centralized global error handler. This Skill provides code examples to catch and process errors consistently across your REST or GraphQL backend.

To set up JWT authentication in Node.js, configure specific middleware to validate tokens and secure routes. This Skill demonstrates middleware implementation for authentication, request validation, rate limiting, and logging within your backend service.

Yes, you can use this skill for database integration with PostgreSQL and MongoDB. It provides specific architectural patterns and code examples to connect, query, and manage data within your Node.js backend application.

This Skill covers architectural patterns for both Express.js and Fastify to build scalable APIs. It demonstrates framework setup, middleware implementation, and routing for both, allowing you to choose the best fit for your REST or GraphQL backend performance needs.
