You can compile the basic WASM library provided in [rust-wasm-template](https://github.com/google/comprehensive-rust/tree/main/src/rust-wasm-template) with this command: You can compile the basic WASM library provided in [rust-wasm-template](https://github.com/google/comprehensive-rust/tree/main/src/rust-wasm-template) with this command:
```shell ```shell
cd src/rust-wasm-template/project cd src/rust-wasm-template
wasm-pack build --target web && cp -r pkg ../server wasm-pack build --target web --out-dir static/wasm
``` ```
You can start the web server provided in [rust-wasm-template](https://github.com/google/comprehensive-rust/tree/main/src/rust-wasm-template) with this command: ### Serve static files
Webassembly has to be loaded from an HTTP server in order to be loaded on the brower.
```shell If you have python on your machine, you can simply
cd src/rust-wasm-template/server
cargo run ```
cd rust-wasm-template/static
python3 -m http.server
``` ```
Open the web page on port `8080`. HTML and JS files are provided at [rust-wasm-template/server](https://github.com/google/comprehensive-rust/tree/main/src/rust-wasm-template/server/files). Otherwise a Rust alternative exists and you can install it with
```
cargo install cargo server
```
And run
```
cd rust-wasm-template/static
cargo-server
```
Open the web page on port `8000`. HTML and JS files are provided at [rust-wasm-template/static](https://github.com/google/comprehensive-rust/tree/main/src/rust-wasm-template/static).
