Prerequisites

• Rust toolchain
• wasm-pack (cargo install wasm-pack)
• wasm-bindgen-cli (cargo install wasm-bindgen-cli)
• Node.js + npm (or pnpm/yarn)

Quickstart

1. Build the WASM engine:

wasm-pack build crates/engine --target web --out-dir ../../web/src/wasm --out-name engine --no-typescript --no-opt

2. Install, test, and run the frontend:

cd web
npm install
npm test
npm run dev

Deploy to Vercel

This repo includes vercel.json and scripts/vercel-build.sh to install Rust + wasm-pack, compile the WASM engine, and build the Vite frontend.

The Vercel build script installs Rust + wasm-pack, builds the WASM engine, then builds the Vite frontend using the published pathfinding and pathfinding-indexed crates.
