ICE first tries to make a connection using the host address obtained from a device’s operating system and network card if that fails (which it will for devices behind NATs) ICE obtains an external address using a STUN server, and if that fails as well, traffic is routed via a TURN relay server. It may be able to do that when a direct connection exists between the clients, as well as when a direct connection is not possible (i.e. It is ICE’s job to find the best path to connect peers. It tries all possibilities simultaneously and chooses the most efficient option that works. Interactive Connectivity Establishment ( ICE) tries to find the best path to connect to peers. This is where we’ll make use of STUN and TURN servers. These servers are also required to cope with network address translators (NATs) and firewalls. WebRTC enables peer to peer communication, however, WebRTC still needs servers for clients to exchange metadata to coordinate communication, which is called signalling. In all the chapters of this tutorial, we will be using simple-peer – a simple WebRTC library for video/voice and data channels. WebRTC has been an emerging standard and is still somewhat in flux, so it’s crucial to make sure that whichever library you choose is up to date and well maintained. However, there are many WebRTC libraries available, that provide high-level abstractions and expose only a few methods to users, while handling major uplifting themselves. You will need it for this tutorial.ĭealing with WebRTC directly might be a bit tedious as it generally involves a lot of lines of code.

Copy the Root API key and store it somewhere.

The default “Root” API key has full access to capabilities and channels. In the API keys tab, choose an API key to use for this tutorial.Select an application from “Your apps” in the dashboard.To use an existing application and API key: Copy your private API key and store it somewhere.To create a new application and generate an API key: You can either create a new application for this tutorial, or use an existing one. API keys exist within the context of an Ably application and each application can have multiple API keys so that you can assign different capabilities and manage access to channels and queues.

Step 1 – Create your Ably app and API key In this tutorial, we will build a WebRTC chat using data channels, allowing us to implement chat for multiple people communicating privately.

The DataChannel API provides a generic transport service allowing web browsers to exchange generic data in a bi-directional peer-to-peer fashion.
