Questions tagged [socket.io]

Socket.IO aims to make real-time apps possible in every browser and mobile device, blurring the differences between the different transport mechanisms. It supports multiple transports, such as WebSockets, Flash sockets, long polling, and more, automatically falling back when a transport fails.

Socket.IO is a Node.js package designed to make real-time applications possible and easy in every browser and mobile device. It supports the following transport mechanisms:

  • WebSockets
  • Adobe® Flash® Socket
  • AJAX long polling
  • AJAX multipart streaming
  • Forever Iframe
  • JSONP Polling

Socket.IO includes a JavaScript library that allows for easy programmatic communication with the server.

Some interesting Socket.IO features include:

  • Automatic JSON serialization
  • Namespacing connections over a single multiplexed connection
  • Volatile messages
  • Rooms (logically grouped connections)

API documentation can be found on the project's Wiki.
