What is Node.js?
Node.js is a run time environment which works across platforms and is used for networking and server side applications. To top it up- it is open source as well!
To understand Node.js and its superior functionality better, you need to understand what an event driven program is.
An event driven program, as the name suggests, is driven when a particular event occurs. A trigger is fired due to which a certain function is called. When any such event occurs, Node.js provides an I/O API which is non-blocking in nature. Being non-blocking commands can be executed in parallels, i.e. faster development. This in turn enhances the throughput and scalability of an application. So, if you want to bring event driven programs to your web servers for enhancing the speed, Node.js is for you.
- Node.js adds a new dimension to real time apps such as chats and games. It uses the web socket protocol to make client and server communication really easy. It excels at executing many concurrent connections. Event Loop makes multi user arrangements possible.
- Do you want your applications to work like web servers without software? Well, Node.js can do it for you. It comes with an inbuilt library that allows applications to do just that- run like web servers without the server software.
- This process simplifies installation, un-installation and updating of libraries. It can also stream data into web sockets in a way similar to streaming data into HTTP.
- Apart from its inbuilt capabilities, Node.js being open source has a community which is very active. Discussions and brainstorming in the community has resulted in some great modules which add further capabilities to applications driven by Node.js.
- Although open source, projects developed on Node.js are not out in the open ready to be dropped anytime its volunteers quit. There is a dedicated team of developers and technicians who actually take care of all Node.js applications.
So go ahead and reap the great benefits of using Node.js.
