A new open source project named Ajax Pages has been released. This beast takes JSP/ASP approaches and builds SinglePageApplications using JavaScript.
Ajax Pages is a scripting template engine that enables rapid development of Ajax Web-based Applications, just like GMail, Google Maps, A9 and Backpack, but without having to manipulate complicated Document Object Models to make things dynamic. Based on the experience of JSP, ASP and PHP, Ajax Pages brings easy scripting templates to the client-side. Anyone familiar with these tecnologies will feel at home with Ajax Pages.
