Node.js is popular for APIs, real-time features, web backends and developer tools. It lets teams use JavaScript or TypeScript on the server and offers a large package ecosystem.
Popularity is not dominance for every workload. Reliable Node.js systems still require architecture, security, testing and operations.
Teams can share language knowledge, types and tooling across browser and server code. This can simplify collaboration, though frontend and backend engineering remain distinct disciplines.
Node.js can handle many I/O operations efficiently when blocking work is controlled. CPU-heavy tasks may require workers, queues or separate services.
Node.js is popular because its ecosystem and concurrency model fit many web services. Choose it when those strengths match the workload and team.
Do not use popularity as a substitute for measuring the actual service.
