Summary

In this chapter, we saw how to build a chatroulette using our own instance of PeerServer that is integrated with Express. The website we build had almost all the features that a chatroulette should have. You can now add features such as screen sharing, connecting users of particular a gender with each other, connecting users of a particular age, integrating captcha to prevent spam, and other features of your choice.

At the time of writing, the WebRTC team is working on an API that allows you to retrieve a stream from a screen for screen sharing. As this API is still under development, you can use browser plugins to retrieve a stream from a screen. You can find more about retrieving a stream from a screen using the plugins at https://www.webrtc-experiment.com/Pluginfree-Screen-Sharing/.

In the next chapter, we will discuss bidirectional communication between the client and the server in real time using WebSockets.
