How to run (CLI)

cargo run --release

Play in the browser (WebAssembly)

The same engine (including the alpha-beta AI and the exact endgame solver) also runs in the browser via WebAssembly, with no wasm-bindgen / wasm-pack and no cargo dependencies. The frontend (React + TypeScript, built with Vite) lives in web/.

Prerequisite: the wasm32-unknown-unknown target.

rustup target add wasm32-unknown-unknown

Then, from web/:

cd web
npm install
npm run dev         # dev server with HMR -> http://localhost:5173
npm run build       # production bundle -> web/dist/
npm run preview     # serve the production build to check it
npm test            # run the Vitest suite

npm run dev and npm run build both first run npm run wasm, which builds the .wasm with cargo and copies it into web/public/. Vite serves that as reversi.wasm, which the app fetches at runtime (a plain file:// open will not work, since the .wasm is fetched over HTTP).

To deploy, upload the contents of web/dist/ to any static host.
