Overview

The library is globally available via eyeson and lets you connect to any eyeson room.

Public Interface

Two of the most common things you want to do with the library are:

• Let a user join a room
• Respond to things happening inside the room

In order to receive eyeson room events register a listener using the onEvent method provided. Remember to register a handler before starting a room otherwise you might miss some initial events.

var handleEvent = function() { /* ... */ };

eyeson.onEvent(handleEvent);  // attach listener for eyeson events
eyeson.start(token);          // initiate and join the room
eyeson.destroy();             // destroy and cleanup a session
eyeson.offEvent(handleEvent); // remove listener for eyeson events

Note that start is a convenient shorthand which handles connecting, fetching initial data and joining the room for you. If you want more granular control over this process you can always use corresponding lower level methods:

eyeson.onEvent(function(event) {
  if(event.connectionStatus !== 'connected') {
    return ;
  }
  eyeson.join({ audio: true, video: true });  // join the room with audio and video
});
eyeson.connect(token);                      // prepare connection

Using the EventTarget Web API

If you want to handle the eyeson events via the EventTarget API you can use the following snippet.

eyeson.onEvent(new eyeson.dispatchOn(window));
eyeson.start(token)
/* then listen for events */
window.addEventListener("eyeson_conf", handleEvent);
window.addEventListener("eyeson_conf.receive_chat", handleIncomingChatMessage);

Sending Events

There are two types of sending procedures send and signal. The first method, send, is the default and widely used. However you might require to send some events directly to the current session in that case use signal instead. Which method should be used depends on the event type and is further described in the corresponding event details.

eyeson.send(msg);   // send an event.
eyeson.signal(msg); // send a direct message to the current session.

Find more details about the types of events to be received and send in the events section.

Configuration

Since v1.5.1 eyeson supports SFU mode in Safari (desktop and mobile). If your application encounters any issues, you can switch back to previous behaviour.

eyeson.config.allowSafariSFU = false; // default is true

If you are not planning to provide screen capturing, you can deactivate it in the configuration.

eyeson.config.screencapture = false;
