Crafting Idiomatic APIs with Kotlin and Compose

What’s in a language? What does it mean to be idiomatic? Writing clean, intuitive APIs isn’t just about functionality — it’s about designing interfaces that feel natural and intuitive. With Kotlin and Compose, we have a powerful set of tools and syntax that, when used effectively, can reduce cognitive load and make your APIs both elegant and expressive. In this talk, we’ll dive into the principles of idiomatic Kotlin and explore how they apply to designing Compose APIs. You’ll learn how to leverage Kotlin’s language features, from DSLs and inline functions to advanced type safety and composable conventions, to craft APIs that are a joy to use. By mastering these techniques, you can deliver APIs that not only “work” but truly feel like Kotlin.
