WebRTC Video Chat in 20 Lines of JavaScript (Part 1)

WebRTC, so hot right now. If you haven’t heard of it, WebRTC (Web Realtime Communications) is an API that enables peer-to-peer video, audio, and data communication in a web browser with no plugins, frameworks, or applications required. In this tutorial, we’ll start by building a very simple video chat application that only requires around 20 lines of JavaScript. Our application will enable users to enter a username and call another user between browsers. In our next part, we’ll add some cool features to bolster our WebRTC video app.
