Lightstreamer 5.0 Released with WebSocket Support for Market Data Push

Milan - 20 April 2012

Weswit, a global leader in real-time web solutions, launched a preview release of Lightstreamer 5.0, codename Colosseo.

Lightstreamer is a world-class solution for pushing real-time data over the Web to and from any desktop/mobile browsers and apps. Lightstreamer is used by many financial institutions around the globe to stream market data, news, and orders as part of their dealing platforms (for FX, CFD trading, spread betting, etc.).

The new version of Lightstreamer increases performance, scalability, and security and introduces complete support for WebSockets, enabling bi-directional, full duplex communication over the Web. Even if WebSockets are not yet universally supported by browsers and network infrastructure, Lightstreamer is able to automatically choose the best transport, among the many available, based on the characteristics of each client. The Stream-Sense algorithm will make sure that the real-time data will travel to and from any possible client, connected through any existing proxies and firewalls.

On the client side, a brand new, completely redesigned, JavaScript API is available. The new library interface is much easier to use and to integrate and is the first step toward the Lightstreamer Unified Client API. It means that the other client technologies will follow the same interface in the future, so that switching languages and platforms (e.g. from JavaScript to Objective-C, or from Java to .NET) will be very easy. The new JavaScript API, version 6, uses AMD (Asynchronous Module Definition) to offer full modularization of the library.

The new JavaScript library has now full support for out-of-browser applications, resulting in the possibility of leveraging Lightstreamer inside new JavaScript-based platforms, such as Node.js and PhoneGap.

The new Stream-Sense algorithm, besides supporting WebSockets (in addition to previous transports), is much faster, with impressive performance boost on session start up.

Many other features are available as part of the new JS client library, including a new logging and error management facility as well as new ready-made widgets (a new status indicator and new data grids).

The preview release of Lightstreamer 5.0 Colosseo is already available for free download on Lightstreamer website.
