Minikotlin
TL;DR
Minikotlin is a Kotlin compiler that operates entirely within a browser tab, converting Kotlin source code directly to WebAssembly bytecode. It is built from scratch in C, eliminating the need for traditional backends like JVM or LLVM.
✦ Why It Matters
Engineers can use Minikotlin to compile and run Kotlin code directly in the browser without installing any additional tools.
Key Takeaways
- Compile Kotlin code to WebAssembly without a JVM or LLVM.
- Utilize smart-casting and dynamic dispatch for efficient execution.
- Run Kotlin applications directly in the browser with no additional installations.
- Leverage coroutine support for non-blocking asynchronous programming.
How It Works
Minikotlin compiles Kotlin code into WebAssembly by transforming each class into a garbage-collected struct, with properties represented as struct fields. The compiler processes the code through its own intermediate representations before generating WASM-GC bytecode.
This allows for features like dynamic method dispatch and smart-casting to be efficiently implemented, enabling real-time execution of Kotlin code in web environments.
