JUFK 7-1: Integrate YouTube Data in KMP: Fetch Videos (Ktor, Serialization, Kamel) | Multiplatform

Learn how to integrate YouTube video data into your Kotlin Multiplatform (KMP) app for Android, iOS, and Web. This session focuses on setting up the data fetching layer using Ktor for HTTP requests, Kotlinx Serialization for JSON parsing, and Coil for image loading, laying the groundwork for displaying video content across all platforms.
In this session:
* Add Ktor, Kotlinx Serialization, and Coil dependencies to your KMP project.
* Configure Kotlinx Serialization Gradle plugin.
* Securely inject YouTube API keys for local development and GitHub Actions.
* Implement platform-specific Ktor HTTP clients for Android (OkHttp), iOS (Darwin), Web (JS), and Desktop (CIO).
* Create an abstract YouTubeVideosDataSource and a concrete API implementation.
* Fetch and parse YouTube playlist data using the official YouTube Data API.
* Address and resolve CI/CD linting issues (ktlint, Detekt) in a live-coding scenario.
* Prepare your KMP app for displaying dynamic YouTube video content.
