Janus Room

A Janus client library that provides simple interface to create a minimal-complete conference video room. This is adopted from Janus demo example code but it's JQuery-less and React/Vue friendly.

Install

Basic usage

import Room from 'janus-room';

...

var options = {
  server: server, // required

  // Event handlers
  onLocalJoin: onLocalJoin,
  onRemoteJoin: onRemoteJoin,

  onMessage: onMessage,
  onError: onError,
}

var room = new Room(options);
room.init()
.then(function(){
  room.register({
    room: roomId,
    username: username
  });
})
.catch(function(err){
  alert(err);
});
