Duplicated broadcast messages

[BarryCarlyon]

I raised a similar issue in September 2017

Calling listen inside onAuthorized, listen callback'ed four times

Consider this code: var authed = false; window.Twitch.ext.onAuthorized(function(auth) { console.log('Authorised'); if (authed) { return; } authed = true; window.Twitch.ext.listen('broadcast', function (topic, contentType, message) { console.log('Recv'); // do stuff }); }); Compared to var authed = false; window.Twitch.ext.onAuthorized(function(auth) { console.log('Authorised'); if (authed) { return; } authed = true; }); …

TLDR: don’t listen in onAuthorised basically
