This tutorial from Daily aims to help developers build a real-time video call experience using Web Components and the daily-js library. The tutorial starts by setting up a new account, creating a room URL, and forking the demo repository. It then guides the reader through building a simple video call experience with two participants, including features such as joining the call, seeing and hearing other participants, toggling camera and microphone settings, sharing screens, and leaving the call. The tutorial uses plain JavaScript to demonstrate how Web Components work together to create this experience. Along the way, it explains the basics of Web Components, including custom elements, HTML templates, and Shadow DOM. It also shows how to integrate these components with the daily-js library to access its methods and functionality. Ultimately, the goal is to inspire developers to customize their own video call experiences using Web Components and daily-js.
