eframe template

dependency status Build Status

This is a template repo for eframe, a framework for writing apps using egui.

The goal is for this to be the simplest way to get started writing a GUI app in Rust.

You can compile your app natively or for the web, and share it using Github Pages.

Getting started

Start by clicking "Use this template" at or follow these instructions.

Change the name of the crate: Chose a good name for your project, and change the name to it in:

  • Cargo.toml
    • Change the from eframe_template to your_crate.
    • Change the package.authors
    • Change eframe_template::TemplateApp to your_crate::TemplateApp
  • index.html
    • Chage the <title>eframe template</title> to <title>your_crate</title>. optional.
  • assets/sw.js
    • Change the './eframe_template.js' to ./your_crate.js (in filesToCache array)
    • Change the './eframe_template_bg.wasm' to ./your_crate_bg.wasm (in filesToCache array)

Learning about egui

src/ contains a simple example app. This is just to give some inspiration - most of it can be removed if you like.

The official egui docs are at If you prefer watching a video introduction, check out For inspiration, check out the the egui web demo and follow the links in it to its source code.

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 libspeechd-dev libxkbcommon-dev libssl-dev

On Fedora Rawhide you need to run:

dnf install clang clang-devel clang-tools-extra speech-dispatcher-devel libxkbcommon-devel pkg-config openssl-devel libxcb-devel fontconfig-devel

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 Trunk with cargo install --locked trunk.
  2. Run trunk serve to build and serve on Trunk will rebuild automatically if you edit the project.
  3. Open 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

Updating egui

As of 2022, egui is in active development with frequent releases with breaking changes. eframe_template will be updated in lock-step to always use the latest version of egui.

When updating egui and eframe it is recommended you do so one version at the time, and read about the changes in the egui changelog and eframe changelog.
