List My App

Run in a Browser

Fyne applications can also be run over the web using a standard web browser! A web app created with Fyne will bundle a WebAssembly binary which will run in most modern browsers

To prepare your app to be used over the web we use the “fyne” cli app again, which has a “serve” command for quick testing

go install fyne.io/fyne/v2/cmd/fyne@latest
fyne serve

You will see, after a few moments, that a web server has been started on port :8080. Just open your web browser to https://localhost:8080 and you can use your app!

Packaging for web distribution

The fyne serve command is great for local testing, but just like other platforms you’ll want to be able to distribute your app as well. To prepare the files for upload just use the fyne package command like with regular Packaging.

fyne package -os web

Demo

You can see a Fyne app in action to test on any of your devices by visiting demo.fyne.io.

Limitations

As of release v2.5.0 the web driver is fully supported but is not yet 100% complete, so your app may not be able to use the following features:

File open/save dialog
Storage of Documents

These issues are being worked on and will be resolved in a future release.
