Most languages make you choose: safety or the web. Lumina doesn't.

Lumina is a statically typed, web-native language with HM type inference, algebraic types, and trait-based polymorphism, compiled to JavaScript and WebAssembly. Build reactive UIs, WebGPU workloads, and WASM modules in the same language, with the same type system.

npm install -g lumina-lang

Create hello.lm:

fn main() -> void {
  print("Hello, Lumina!")
}

Run the basic workflow:

lumina check hello.lm
lumina compile hello.lm --target esm --out hello.js
node hello.js

Start the REPL:

• lumina CLI for check, compile, run, grammar, bundle, and REPL workflows
