Testing locally

Make sure you are using the latest version of stable rust by running rustup update.

cargo run --release

On Linux you need to first run:

sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev

On Fedora Rawhide you need to run:

dnf install clang clang-devel clang-tools-extra libxkbcommon-devel pkg-config openssl-devel libxcb-devel gtk3-devel atk fontconfig-devel

Web Locally

You can compile to WASM and publish it as a web page.

We use Trunk to build for web target.

1. Install Trunk with cargo install --locked trunk.
2. Run trunk serve to build and serve on http://127.0.0.1:8080. Trunk will rebuild automatically if you edit the project.
3. Open http://127.0.0.1:8080/index.html#dev in a browser. See the warning below.

assets/sw.js script will try to cache our app, and loads the cached version when it cannot connect to server allowing your app to work offline (like PWA). appending #dev to index.html will skip this caching, allowing us to load the latest builds during development.
