Question 1

What is Node.js?

Accepted Answer

Node.js is an open-source, cross-platform JavaScript runtime built on Chrome's V8 engine that executes JavaScript code outside a web browser. It uses an event-driven, non-blocking I/O model, making it well-suited for building fast network applications and APIs. Node.js lets developers use JavaScript for both frontend and backend code, reducing context-switching on a team.

Question 2

What is Node.js used for?

Accepted Answer

Node.js is most commonly used for building RESTful and GraphQL APIs, real-time applications like chat and live dashboards, microservices, and serverless functions on platforms such as AWS Lambda and Vercel. It is also the runtime behind frameworks like Next.js and Fastify. Because it handles many concurrent connections efficiently, it fits data-intensive workloads well.

Question 3

Is Node.js good for backend APIs?

Accepted Answer

Yes. Node.js excels at I/O-heavy backend APIs because its non-blocking event loop allows it to handle thousands of simultaneous connections without spawning a new thread per request. Frameworks like Express and Fastify layer routing and middleware on top, so teams can ship production APIs quickly. For CPU-bound tasks, worker threads are available to avoid blocking the event loop.

Question 4

Node.js vs other backends: why choose it?

Accepted Answer

Node.js shares a language (JavaScript/TypeScript) with the browser, which means frontend developers can contribute to the backend without learning a new language. The npm ecosystem offers over two million packages, and the V8 engine delivers strong raw performance. Compared with interpreted-language runtimes, Node.js performs competitively on networked workloads while keeping infrastructure lean.

Question 5

Do you build Node.js backends?

Accepted Answer

Yes. Savage Digital Solutions builds Node.js backends for clients who need fast, maintainable APIs and server-side services. We pair Node.js with TypeScript for type safety, Docker for consistent deployments, and PostgreSQL or MongoDB depending on the data model. If your project requires a custom API, a real-time service, or a microservices architecture, we can scope and build it.
