Chapter 4. Creating a Signaling Server
At some point when creating a WebRTC application, you will have to break away from developing for a client and build a server. Most WebRTC applications are not solely dependent on just being able to communicate through audio and video and typically need many other features to be interesting. In this chapter, we are going to dive into server programming using JavaScript and Node.js. We are going to create the basis for a basic signaling server that we can utilize through the rest of the book.
In this chapter, we will cover the following topics:
- Setting up our environment to develop in Node.js
- Connecting to the client using WebSockets
- Identifying users
- Initiating and answering a WebRTC call
- Handling ICE candidate transfers
- Hanging up a call
Throughout this chapter, we are going to focus solely on the server part of the application. In the next chapter, we will build the client part of this example. Our example server will be bare bones in nature, giving...
