# Calyx Web Demo
This web demo uses `calyx` as a library, compiled to WebAssembly, to provide an
interactive in-browser interface for the Calyx compiler.
## Requirements
You will need [Rust][] and [Node.js][] and [NPM][] or [Yarn][].
To get [WebAssembly support][wasm-qs] in Rust, the easiest way is to use [rustup][] rather than installing Rust with a package manager.
Then install `wasm-pack` with:
```shell
cargo install wasm-pack wasm-bindgen-cli
```
## Build and Run
First, install the dependencies by typing `yarn` or `npm i`.
Then, launch a local web server (which will also rebuild the site when source files change) by typing `yarn start` or `npm start`.
To build standalone web files, use `yarn build` or `npm run build`.
