JWT-based authentication in a Node.js backend secures your application by validating tokens sent from the client. This guide provides patterns for implementing JWT authentication alongside authorization middleware to protect your API routes.

RESTful API design best practices in Node.js ensure scalable and maintainable web application backends. This guide covers implementing RESTful APIs and GraphQL backends using Express or Fastify with proper middleware and error handling patterns.

Database integration with a Node.js application connects your backend to SQL and NoSQL data sources. This guide offers detailed patterns for integrating both database types into scalable Node.js services without locking you into a specific ORM.

Express and Fastify are both supported for building scalable Node.js applications in this guide. It targets middleware patterns and API design across both frameworks, allowing you to choose based on your specific performance and architecture needs.

Middleware and error handling in production-ready Node.js services process requests sequentially and catch runtime exceptions globally. This guide details how to implement these patterns to build maintainable backend applications that fail gracefully.
