Build

WASM for Node.js

bash cargo install wasm-pack wasm-pack build --release --target=nodejs -- --features wasm

WASM for Web

bash cargo install wasm-pack wasm-pack build --release --target=web --out-dir=examples/web/lib -- --features wasm cd examples/web npm install && npm run build cd dist && python3 -m http.server

Reason

And... yes this is the real inspiration behind the emulator's name:
