9: Reading feed data from multifeed

Now that we have created a multifeed, each hypercore represents a different user in the application. When we replicate with another multifeed peer, we download their feeds and upload ours.

multifeed.feeds() returns a list of feeds, which are just hypercore objects (ie. they each have a createReadStream() function)..

multi.ready(function () {
  var feeds = multi.feeds()
  feeds.forEach(function (feed) {
    // feed is a hypercore! (remember reading from hypercores in previous exercises?)
  })
})

Exercise

Using console.log, write all chat messages to the screen from every hypercore in the multifeed. Have it iterate over all chat messages from all hypercores.

Tips

• feed.createReadStream(options) has an option called {live: true}. If you set this, the stream will stay open and keep emitting new data as it is appended to the hypercore.
• You can always create more feeds locally by calling multi.writer(function (err, feed) {}).
