Node.js is an innovative, event-driven non-blocking I/O platform used for sites which support live communication. Several instances of such sites would be web-based browser video game portals, online chat rooms or accommodation reservation portals. Node.js processes the information exchanged between the site and its users in small bits, which boosts the loading speed and the overall performance of the website substantially. If a certain form with three boxes has to be filled out by a user, for example, typically all three boxes should be filled and the whole content is then submitted as one giant chunk of information to the server. With Node.js, the first box’s content is processed as soon as it is entered, before the user writes anything in the second one. In this way, a lot more info can be processed much faster and more effectively compared to any conventional platform, which can exert an immense impact on the site’s overall performance. Node.js is already being used by many of the biggest IT corporations such as Microsoft and Yahoo.
