JanusHelper methods

setConfig(config), init

import { JanusHelper } from 'janus-helper'

const config = {
  debug: true || false, // set console will log information for debug or not
  server: 'wss://localhost:28989/', // set janus server wss url address 
};

const janus = new JanusHelper(config);

// after setConfig init the janus and create session for later usage.
janus.init();

injectPlugin(plugin instance, basic inforamtion {}, callbacks {}) that would return a plugin handler through Promise

Image this processs is dealing with attaching plugin to a running session.

import { JanusHelper, plugins } from 'janus-helper'

    unigueRoomId, // the id for identify each room instance e.g. uuid()
  },
  userInfo: { // user info -> required
    id: '1234',
    name: 'testname',
  }, 
  // extra field for other usage -> optional for VideoRoom plugin
  filename: 'filename', // the rec video file name
  rec_dir: '/path/to/recordings-folder/', // the rec video file path to janus-server

    notify_joining: true,

      new feeds (publishers), and enabling this may result extra notification
      traffic. This flag is particularly useful when enabled with \c require_pvtid
      for admin to manage listening only participants. default=false)
