Updating web content in real time using Node.js

Abstract

The real-time web is a set of technologies and practices that enable users to receive information as soon as it is published by its authors, rather than requiring that they or their software check a source periodically for updates. In order to achieve this, we can use different technologies. One of them is Node.js. Through this article we want to describe this technology and highlight the advantages of using Node.js as a technology to update web content in real time. To achieve this objective we have made some tests and measurements for the time spend to update information using these technology versus other technologies like Php/ Apache.
