Lightstreamer is a push server for live data distribution to âzero-installâ clients, based on the Comet paradigm (also known as âStreaming AJAXâ or âAJAX Pushâ). The role of Lightstreamer software is to deliver any real-time data from the server to the browser in a fast and reliable way. Once the data has reached the browser, the Dojo Toolkit is a perfect option to incorporate and use it inside a state-of-the-art AJAX application.
SitePen, a web development & consulting firm based in Silicon Valley, has developed a proof of concept that demonstrates a Dojo application that subscribes to live security prices published by Lightstreamer Server and displays them inside a Dojo table. The recent release of the Dojo Charting Tool has been leveraged to display the live prices in a graphical format as well. Streaming charts based on pure thin clients (with no applets, plug-ins or other external components) are a leading-edge application of the Comet paradigm, that will be especially appreciated by financial institutions.
âThis demonstration further emphasizes the possibilities of the real-time webâ, said Dylan Schiemann, CEO of SitePen, Inc. and co-founder of the Dojo Toolkit. âDojo's widget system and event model are well-suited for integrating with Lightstreamerâs Comet server. Quite frankly, we were blown away by the ease and simplicity of getting Lightstreamer up and running within just a few minutes.â
âThe seamless integration between Lightstreamer and Dojo is an important achievementâ, said Alessandro Alinone, CTO of Lightstreamer. âWe are a very focused company and our goal is not to provide a general AJAX framework. Our mission is to deliver a high-performance and reliable push server that can work with any AJAX solution. Thatâs why Lightstreamer has recently entered the OpenAjax Alliance.â
