GeoJSON Viewer

Just a small demo to try out egui and geojsons in Rust.

Web Locally

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

We use Trunk to build for web target.

  1. Install the required target with rustup target add wasm32-unknown-unknown.
  2. Install Trunk with cargo install --locked trunk.
  3. Run trunk serve to build and serve on http://127.0.0.1:8080. Trunk will rebuild automatically if you edit the project.
  4. 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.

Web Deploy

  1. Just run trunk build --release.
  2. It will generate a dist directory as a "static html" website
  3. Upload the dist directory to any of the numerous free hosting websites including GitHub Pages.
  4. we already provide a workflow that auto-deploys our app to GitHub pages if you enable it.

To enable Github Pages, you need to go to Repository -> Settings -> Pages -> Source -> set to gh-pages branch and / (root).

If gh-pages is not available in Source, just create and push a branch called gh-pages and it should be available.

You can test the template app at https://emilk.github.io/eframe_template/.
