DESCRIPTION
In the last couple of years we have seen an explosion of single-page applications beyond the traditional complex applications, making its way into the mainstream and the consequent appearance of frameworks to facilitate the creation of these apps. In this session we will cover the motivations and implications of creating single-page apps, as well as the current state of the industry, the trends that are starting to arise in the field and the role of nodejs to facilitate the initial render process on the server side before handing over the control to the browser, as a way to speed up the initial rendering on mobile devices.
