Fable-Elmish-Electron-Material-UI demo Build status

This is an example of an F# Electron app centered around Fable 2 and Elmish. The actual app contents (which you can easily replace to build your own Electron app) are intended to show how to use Material-UI (including JSS/style-as-code) as well as serve as examples of how to implement some (not always trivial) UX patterns in Elmish.

To use the demo for scaffolding your own Fable/Elmish/Electron apps, simply clone the repo and start hackin' on the Renderer project to get started (details below).


  • Hot module reloading for both code and styles
  • Time-travel debugging (using Redux DevTools, RemoteDev, and Fable.Elmish.Debugger)
  • Single-command development and packaging with FAKE
  • electron-webpack takes care of most of the webpack config
  • electron-builder packages the app (see their documentation for how to customize)
  • electron-window-state for remembering window state between launches
  • Devtron for Electron-specific debugging/linting

Stuff demoed:

  • Autocomplete
  • Badges
  • Dialogs
  • Saving/loading files
  • Selects (dropdowns)
  • Snackbars
  • Static assets (images etc.)
  • Text fields / input validation

How to develop

This project uses .NET Core 3 local tools. Therefore, run dotnet tool restore to restore the necessary CLI tools before doing anything else.

Then, to run the app locally in "live mode":

dotnet fake build -t Dev

(Dev is the default target, so you can also just run dotnet fake build.)

After the app starts, edit the renderer project in /src/Renderer and see the changes appear in real-time thanks to hot module reloading.

Place static files in the root /static folder as required by electron-webpack. See the code for the “Static assets” page (and the helpers in Utils.fs) to see how to use them.

Release build to unpacked directory

dotnet fake build -t DistDir

Release build to packed installer

dotnet fake build -t Dist

NuGet package management

Use dotnet paket (after running dotnet tool restore).

Improvements welcome!
