Node.js is a type of cross-platform, open source runtime that is built on Chrome JavaScript. It is meant to help with the development of fast and scalable networking and server-side applications. As an interface to V8 JavaScript runtime, Node.js enables efficient event-driven programming for the web servers with the help of superfast JavaScript interpreter running in Chrome browser. The specialty of Node.js is that it operates on a dedicated non-blocking I/O model which makes it perfectly clean and usable. It also makes Node.js ideal for various real-time data-intensive applications that must perform in a variety of environments. Going past the conventional working models, Node.js has ushered a revolution within the development circle. It is now sought after by leading brands such as Yahoo, Walmart and eBay and is strongly recommended by web development firms like WebzGuru.
Node.js effectively authorizes various instantaneous web applications and it is done simply by making use of a push technology against the web sockets for building different types of server-side web applications through the two-way channel of client and server. Node.js makes use of open web stack systems and technologies such as JavaScript, HTML and CSS that operate over standard port 80. The tool is also perfectly lightweight for the purposes of in-memory usage as well as real-time data dense web applications that run on multiple devices. Such advantages make Node.js the ultimate choice for the developers as they can make use of it to create various enterprise friendly apps that operate on speedy, lightweight and high-traffic models.
Node.js offers great speed
Node.js runs on V8 engine created by Google which makes use of JavaScript for its native machine code. It is known for functioning at a very high speed. One of the main reasons for this is that Node.js eradicates all need of working with separate threads and uses one single thread instead to manage all asynchronous I/O operations. Major web application related actions like writing or reading to the database, file systems or network connections can be quickly performed with the Node.js suite.
Widespread presence in servers and browsers
Due to the extensive usage of Node.js, JavaScript is now available in the server as well as the browser. The Node.js code functions everywhere in a similar way and offers great flexibility in terms of usage.
Efficiency in data streaming
In web platforms, the HTTP requests and the HTTP responses are typically considered as two separate events. However, in reality they are both data streams. Such a feature can be used with Node.js for processing files during the time of uploading. This can help to bring down overall processing time while dealing with data streams. The same strategy can also be applied for real-time audio or video recording.
Developing real-time web applications
With the help of Node.js, it is perfectly possible to real top quality real-time web applications at high speeds. The suite that comes with Node.js can help greatly in creating web apps like chat apps and games that can be used in real time by multiple users.
