Top Node.js Agencies

Node.js is a JavaScript runtime built on the V8 engine that allows JavaScript to run outside the browser. It is widely used for APIs, backend services, command-line tools, automation, real-time applications, and full-stack JavaScript development. Node.js uses an event-driven architecture that works well for I/O-heavy workloads such as web requests, database operations, and network services. Its large package ecosystem supports authentication, databases, testing, queues, file processing, and integrations, making it a common choice for modern backend systems.

For projects using Node.js, teams should consider the application's requirements, expected scale, integration points, deployment environment, testing approach, and long-term maintenance. Choosing the technology should also take into account the existing skills of the development team and the libraries or services already used by the product.
