Mastering Libri GmbH Mastering Kotlin Multiplatform Development

Build once. Deliver everywhere.

Modern applications are expected to run seamlessly across Android, iOS, desktop, and the web. Mastering Kotlin Multiplatform Development shows you how to build production-ready cross-platform applications while sharing business logic, reducing duplicated code, and maintaining native performance and user experience.

Mastering Kotlin Multiplatform Development is a practical, project-driven guide that teaches you how to build scalable applications using the latest Kotlin Multiplatform ecosystem. Rather than relying on outdated patterns or unnecessary theory, this book focuses on modern development practices that can be applied immediately in real-world projects. You'll learn how to organize shared code, implement clean architecture, build responsive user interfaces with Compose Multiplatform, consume REST APIs with Ktor, manage local data with SQLDelight, and write asynchronous code using Coroutines and Flow.

Throughout the book, you'll develop production-style applications while exploring dependency injection with Koin, MVVM architecture, testing strategies, deployment for multiple platforms, and techniques for building maintainable, reusable codebases. Whether you're expanding your Android skills or entering cross-platform development for the first time, this guide provides the practical knowledge needed to build modern applications from a single shared codebase.

What You'll Learn
- Build Android, iOS, desktop, and web applications from a shared Kotlin codebase.
- Design reusable business logic using Kotlin Multiplatform best practices.
- Build modern user interfaces with Compose Multiplatform and effective state management.
- Integrate networking with Ktor, local persistence with SQLDelight, and asynchronous programming with Coroutines and Flow.
