How to use config.js?

iDLE · May 20, 2021, 8:09pm

We have options to create conference in lib-jitsi-meet project.(I call it optionA)

jitsi/lib-jitsi-meet/blob/master/doc/example/example.js#L3

    
      
          /* global $, JitsiMeetJS */
          
          
const options = {
              hosts: {
                  domain: 'jitsi-meet.example.com',
                  muc: 'conference.jitsi-meet.example.com' // FIXME: use XEP-0030
              },
              bosh: '//jitsi-meet.example.com/http-bind', // FIXME: use xep-0156 for that
          
          
    // The name of client node advertised in XEP-0115 'c' stanza
              clientNode: 'http://jitsi.org/jitsimeet'
          };

And use it here

github.com

jitsi/lib-jitsi-meet/blob/master/doc/example/example.js#L246

    
      
          $(window).bind('beforeunload', unload);
          $(window).bind('unload', unload);
          
          
// JitsiMeetJS.setLogLevel(JitsiMeetJS.logLevels.ERROR);
          const initOptions = {
              disableAudioLevels: true
          };
          
          
JitsiMeetJS.init(initOptions);
          
          
connection = new JitsiMeetJS.JitsiConnection(null, null, options);
          
          
connection.addEventListener(
              JitsiMeetJS.events.connection.CONNECTION_ESTABLISHED,
              onConnectionSuccess);
          connection.addEventListener(
              JitsiMeetJS.events.connection.CONNECTION_FAILED,
              onConnectionFailed);
          connection.addEventListener(
              JitsiMeetJS.events.connection.CONNECTION_DISCONNECTED,
              disconnect);

I am confused this option with (optionB)

github.com

jitsi/jitsi-meet/blob/master/config.js#L3

    
      
          /* eslint-disable no-unused-vars, no-var */
          
          
var config = {
              // Connection
              //
          
          
    hosts: {
                  // XMPP domain.
                  domain: 'jitsi-meet.example.com',
          
          
        // When using authentication, domain for guest users.
                  // anonymousdomain: 'guest.example.com',

I know this is the option in /etc/jitsi/meet/my.domain-config.js

What is the difference between optionA and optionB?

Can I use portion of optionB for optionA?
Is optionB used by jitsi-meet frontend? or by jvb&jicofo?

And for example, if I want to control camera resolution, should I modify optionA(in code) or optionB(in server - /etc/jitsi/meet/my.domain-config.js)?
And If I want to change camera resolution from setting dialog)?

While I have never written code using lib-jitsi-meet, I think that there is only a logical answer: when you use lib-jitsi-meet, you are replacing the default jitsi application (the JS part) to develop your own interface. If config.js was used by lib-jitsi-meet, it would mean that the server administrator could change the behaviour of your app ‘behind your back’. It would not be a good way to proceed (even if the server administrator can still configure Jicofo and Jvb server behaviour and it’s not meaningless of course; but as far as your app (client side) is concerned, Jicofo and jvb are controlled by your app through lib-jitsi-meet). That’s my 0.02 euro (I’m not a Jitsi developer)

Thank you for your answer.
I want to know if I replace default jitsi application, then /etc/jitsi/meet/my.domain-config.js is lo longer needed? or yet used by jvb/jicofo?

Option A is a meeting api-level option. It impacts only the meetings started with these settings.

Option B is applies to all meetings on the server.

Thanks, always, @corby.

So do you mean /etc/jitsi/meeting/my.domain-config.js is used by server(jvb or jicofo)?

gpatel-fr · May 20, 2021, 9:58pm

config.js is never used by jicofo or jvb.

corby · May 21, 2021, 12:36am

/etc/jitsi/meeting/my.domain-config.js is sent to your clients (by nginx) when someone joins a meeting (either by web or iOS/Android app)

very clear answer for me. That was I just wanted.

So I need config.js, even though I don’t use jitsi-meet default app, right?

corby · May 21, 2021, 10:20am

Yes. config.js is the primary settings and configuration file for all clients who connect to your meetings.
