This quality makes Node.js servers very scalable. Highly ScalableĮven though Node.js employs a single-threaded model, its event mechanism helps its server respond in a non-blocking manner. A Node.js event notification would help the server in getting a response from its last API call.Ĭheck out upGrad’s Advanced Certification in Cyber Security 2. The server would call an API and move to the next one. This means a Node.js-based server doesn’t have to wait for an API to return any data. The APIs of Node.js’s library are non-blocking (asynchronous). The following are some qualities of Node.js that make it the preferred choice of many developers and software architects: 1. It is cross-platform too, which lets developers use it on different platforms.Ĭheck out upGrad’s Advanced Certification in DevOps It is an open-source runtime environment to develop networking applications. It uses a non-blocking, event-driven I/O model, allowing it to remain efficient and lightweight.ĭue to those qualities, Node.js is suitable to build real-time applications that require a lot of data and can run across various distributed machines. Node.js’s primary application is to help developers in building quick and scalable network applications. Node.js is a runtime environment based on JavaScript, a widely-used programming language. What is the difference between web development and web designing?
