API

server.channel.subscriptions(cb)

Get the channels and who is subscribed where cb(err, data) is called with data of form:

{
  [ChannelName]: Set  // set of FeedIds of users subscribed to that channel 
}

e.g

{
  'ssb-learning': Set { '@gaQw6z...', '@ye+QM09...' },
  'brazil': Set { '@gaQw6z...' }
}

Check your Set methods on MDN

And if you really need an Array :

const s = new Set ()
set.add('mixmix')
set.add('soapdog')

[...s]         // => ['mixmix', 'soapdog']
Array.from(s)  // => ['mixmix', 'soapdog']

server.channel.get(cb)

Get the current state of the channel view. This will wait until the view is up to date, if necessary.

cb(err, data) is a standard callback function where data is of the form:

{
  [ChannelName]: Set  // set of FeedIds of users subscribed to that channel 
}

server.channel.get(cb)
