Why should a development team choose Node.js? It is a single language on client and server. It is exceptionally easy to install and get running. Npm is pretty cool and websockets module is neat. Let’s dive deeper into advantages of Node.js in this article.###What is Node.js?
Node.js has an event-driven architecture capable of asynchronous I/O. These design choices are meant to optimize throughput and scalability in Web applications with many input/output operations, as well as for real-time Web applications (e.g., real-time communication programs and browser games).###The most-used programming language
Traditionally, I/O operations either run synchronously (blocking) or asynchronously by spawning off parallel threads to perform the work. This old approach consumes a lot of memory and is notoriously difficult to program. In contrast, when a Node application needs to perform an I/O operation, it sends an asynchronous task to the event loop, along with a callback function, and then continues to execute the rest of its program. When the async operation completes, the event loop returns to the task to execute its callback.
In other words, reading and writing to network connections, reading/writing to the filesystem, and reading/writing to the database–all very common tasks in web apps–execute very, very fast in Node. Node allows you to build fast, scalable network applications capable of handling a huge number of simultaneous connections with high throughput.
It makes extremely easy to prototype (almost) any kind of web application in a shorter time when compared with others like for example JAVA and LAMP. Just to mention some of the savings in time: node.js provides the web server module itself, so you don't have to own knowledge about setting up Apache or NGINX unless you want to integrate in the existing platform or you have a complex system architecture, and the very active node.js community provides ready-to-use modules and deep knowledge that can save you time when it comes to develop commodity features (Facebook-Connect, RESTful API, templating).
3.Super productive: use a single language on Server side, Client side and Mobile
4.World leading companies have already switched to Node.js
All of these companies (and many more not listed, like Intel, HP and IBM) have published either extensive reports or blog articles on how they evaluated all the technology out there and switched to Node for either their flagship products or their new products.
As with any platform or product, open-source or otherwise, its community is a huge influencing factor. And Node's is second to none. From meetups to conferences, there are really smart people working on the ecosystem every day. At the same time, the community is welcoming. These same smart people are always willing to offer help to folks new to Node, or even programming in general. You won't feel bad for asking a question on IRC or opening an issue. This community is also very active, with over 91,000 modules on npm. And this community is generous. In 2013, individuals donated over $70,000 to help run the public npm servers.
Yes, Node is trendy at the moment. This is web development, so next week Node may be dead, and the next hot thing will have arrived. But give it a try.
