It is not advisable to use Node.js for CPU intensive applications. Data Intensive Real-time Applications (DIRT).Where to Use Node.js?ДЇollowing are the areas where Node.js is proving itself as a perfect technology partner. The following diagram depicts some important parts of Node.js which we will discuss in detail in the subsequent chapters. Projects, Applications, and Companies Using Node This list includes eBay, General Electric, GoDaddy, Microsoft, PayPal, Uber, Wikipins, Yahoo!, and Yammer to name a few.

No Buffering в€’ Node.js applications never buffer any data. Node.js uses a single threaded program and the same program can provide service to a much larger number of requests than traditional servers like Apache HTTP Server. Event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests. Single Threaded but Highly Scalable в€’ Node.js uses a single threaded model with event looping.

Very Fast в€’ Being built on Google Chrome's V8 JavaScript Engine, Node.js library is very fast in code execution. The server moves to the next API after calling it and a notification mechanism of Events of Node.js helps the server to get a response from the previous API call. It essentially means a Node.js based server never waits for an API to return data.

Node.js = Runtime Environment + JavaScript LibraryДЇollowing are some of the important features that make Node.js the first choice of software architects.ДЄsynchronous and Event Driven в€’ All APIs of Node.js library are asynchronous, that is, non-blocking. Node.js also provides a rich library of various JavaScript modules which simplifies the development of web applications using Node.js to a great extent. Node.js applications are written in JavaScript, and can be run within the Node.js runtime on OS X, Microsoft Windows, and Linux. Node.js is an open source, cross-platform runtime environment for developing server-side and networking applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Node.js is a platform built on Chrome's JavaScript runtime for easily building fast and scalable network applications. The definition of Node.js as supplied by its official documentation is as follows в€’ Node.js was developed by Ryan Dahl in 2009 and its latest version is v0.10.36. Java is a registered trademark of Oracle and/or its is a server-side platform built on Google Chrome's JavaScript Engine (V8 Engine). For details, see the Google Developers Site Policies.
