FAQPage Schema
How do I structure a Node.js backend for production?▼

Structure a Node.js backend using layered architecture, separating controllers, services, and repositories. This approach implements dependency injection and transaction management to build robust, production-ready REST APIs or microservices.

What is the best way to handle errors in Express and Fastify?▼

The best way to handle errors in Express and Fastify is implementing custom error classes and a global error handler. This pattern standardizes response formatting and manages exceptions across middleware consistently.

How do I implement authentication and rate limiting in Node.js APIs?▼

Implement authentication and rate limiting in Node.js APIs by configuring middleware. This approach integrates validation and logging mechanisms to secure REST API endpoints and prevent abuse.

Can I use Redis caching with a Fastify or Express REST API?▼

Yes, you can integrate Redis caching with Fastify or Express REST APIs. Implementing caching strategies optimizes database integration by reducing query loads and improving response times.

Does this Node.js approach support both PostgreSQL and MongoDB?▼

Yes, this Node.js approach supports database integration for both PostgreSQL and MongoDB. It provides implementation examples for transaction management and data persistence within a layered architecture.
