This tutorial series aims to help developers build a custom Daily app using SvelteKit. The project uses Daily's REST API to create new rooms and navigate between different pages. The routing is based on the file structure in SvelteKit, with separate files for the home page, room form, and custom endpoint for creating rooms. The tutorial covers how to set up the file structure, create a form to submit room requests, handle errors, and navigate to the newly created room using SvelteKit's route-based endpoints. The completed demo app is publicly available on Github, allowing developers to get started with building their own custom Daily video chat app.
