What is Lift ?

Lift is one of the most mature web application development frameworks written for the Scala programming language. It has been designed to build sophisticated, rich and vibrant web applications using Scala, a hybrid programming language incorporating both functional and object oriented capabilities.

Why develop web applications using Lift ?

Lift has been particularly developed for those web developers who want to build highly interactive, real-time web applications that push data to the browser when needed, without users having to send requests to the server. Lift uses technologies such as Comet or Ajax, to be able to build this type of applications.

Security has been a major design goal for Lift creators, and this is reflected in the fact that Lift web applications are protected against SQL injection, CSRF (cross-site request forgery), XSS (cross-site scripting) , and many other attacks without web application developers needing to do any extra configuration or work.

Since Lift is built on top of Scala, it enables development of web applications that are very concise, and Lift itself comes with a lot of utilities that help web developers build applications with less code.

Based on an architecture designed around well-formed HTML5 or XHTML template views and snippets that get injected into the templates, it offers a clear separation between the work done by web UI designers and web developers. This guarantees that designers won't introduce problems as a result of modifying web framework specific code within template.

FourSquare or Montreux Jazz Festival are examples of companies that have developed Lift based web applications. These applications are subject to enormous traffic spikes, and are living proof that Lift applications are scalable and resilient.

To find out more about developing Lift applications, Lift In Action book offers a comprehensive, detailed guide to writing Lift web applications following best practices.

Why deploy Lift applications on Escalante ?

Escalante allows you to deploy Lift web applications in a way that optimises the size of the deployment and the memory consumption at runtime, both of which are of paramount importance. Escalante does however still allow you to deploy standard Lift applications. For more info, check the documentation.
