Building Modern Web Apps with Kotlin and WebAssembly

Zalim Bashorov - JetBrains

Kotlin is a modern statically typed programming language developed by JetBrains, designed to be used across different platforms. WebAssembly a portable binary format, designed to be fast and safe, enables running high-performance code in various environments.

Kotlin/Wasm aims to combine these two technologies and provide the best experience for building everything from high-performance web applications to serverless functions.

In this talk, we will explore how Kotlin and WebAssembly can be used together to build modern, high-performance web applications. You will learn how to leverage browser APIs and existing libraries effectively. We will examine different approaches to building UIs, from direct DOM manipulation to using Compose Multiplatform, highlighting the trade-offs and performance considerations.
