More FAQs in When to Use Node.js: Real-World Use Cases and When to Avoid It
REST APIs, real-time apps like chat and notifications, single-page app backends, and microservices. Its non-blocking architecture makes it excellent for high-concurrency I/O-bound work.
For CPU-heavy work like ML, video processing, and heavy computation, since these block the event loop. Also for large-scale data processing, where Python's rich data ecosystem is better.
Yes. Node.js is lightweight, fast to start, and uses JavaScript, which many teams already know. These properties make it good for microservices, especially when the team is full-stack JavaScript.
