This series aims to help developers build their own webinar platform using Daily Prebuilt and a custom chat widget, focusing on efficiency and speed. Recently, Daily updated its prebuilt UI with new properties and instance methods to facilitate faster development for the webinar use case. The first tutorial in this series will guide users through initializing a new create-react-app repository, adding the daily-js dependency, and embedding a Daily call into a WebinarCall React component. By the end of this tutorial, users will have a basic React app with a Daily video call embedded in it, laying the foundation for further development and customization to meet their specific needs.
