Build a scalable Node.js backend by leveraging modern ESM and async/await patterns with the Express framework to structure robust RESTful APIs. This approach ensures clean routing, efficient middleware, and maintainable backend service architecture.

Integrate PostgreSQL with an Express API by utilizing Prisma ORM for type-safe database operations. This combination provides efficient query management and streamlined schema migrations within your Node.js backend application.

Deploy a Node.js application using Docker for containerization and PM2 for process management. This strategy ensures high availability, performance optimization, and streamlined production deployment for backend applications.

Asynchronous programming improves Node.js performance by utilizing async/await to manage non-blocking I/O operations. This mechanism prevents event loop congestion and allows the backend to process concurrent requests highly efficiently.

Yes, you can use Vitest to test an Express backend. Vitest provides a modern testing framework that integrates smoothly with Node.js, ensuring your API endpoints, authentication, and database operations function correctly.

Optimize streams in a Node.js API when handling large data payloads or continuous data flows. Streams prevent excessive memory consumption by processing data in chunks, which is essential for maintaining backend performance.
