Atmosphere Framework: Open-Source Asynchronous Web App Framework

The Atmosphere Framework is an open-source asynchronous web application framework for the Java platform. It allows bi-directional communication between client and server without page refresh, allowing real-time web applications.

What is Atmosphere Framework?

The Atmosphere Framework is an open-source asynchronous web application framework for the Java platform. It allows for real-time, bi-directional communication between the client and server without needing page refreshes. This enables the development of Web applications with near instantaneous response times similar to desktop applications.

Some key features of Atmosphere include:

  • Support for different transports like WebSockets, SSE, Long-Polling, and others
  • Integration with major Java web frameworks like Spring, Guice, and JBoss
  • Broadcasting of messages from server to multiple suspended client connections
  • Clustering support for scaling to many concurrent users
  • Pluggable architecture that is framework and server independent
  • Variety of client-side JavaScript frameworks to communicate with like jQuery, Dojo, backbone.js

Atmosphere is commonly used to build chat applications, social platforms, real-time dashboards, browser-based multiplayer games, live sports/election trackers, and other systems requiring low latency between user interactions. It handles the complexity of maintaining long-lived connections and transmitting data efficiently across that channel.
