Eel VS pywebview

I gave up a long time ago attempting to write GUIs in pure python. I've come back to them periodically to see if the landscape has changed, but I'm always disappointed.

My current go-to python GUI solution is to use the Eel library. It renders GUIs in a web-browser like window with HTMl/CSS/JS.It lets you expose your python functions to JavaScript, so data can be easily transferred back and forth between the python and the JavaScript. And since it's just web-dev, it's pretty easy to make things look and feel good enough. Any other web-dev libraries like bootstrap and jquery can be used. It works pretty well for writing GUIs that put data analysis tools in front of my colleagues.

Eel was used to implement the app and communication with the web interface.

I am calling a function from Python using eel and taking the return value. Python functions are asynchronous with JavaScript by nature. This code is combined with other variables to determine if the form can continue. allFilled() is called everytime the form field changes.

In the past, I've used QT4 and QT Designer. It was okay. It was a small mountain to climb for myself then - but certainly doable. However, there was a lot of generated code that wasn't the most concise thing. Today, I discovered Eel. Since I used QT4 in the past, I've done some web dev. Certainly, not proficient there. But Eel wasn't as big of a hurdle. In fact, it took me a fraction of the time because it is much like creating a basic website. Where there's an abundance of tutorials and tips out there for everything imaginable. Instead of downloading and adding a font, clicking through a bunch of dialogs. I just linked a Google font and updated the CSS. Stuff like that.

If you don't want a web-app, you can still use JS for GUI, using something like python-eel https://github.com/python-eel/Eel

In case anyone else is unfamiliar:

> pywebview uses native GUI for creating a web component window: WinForms on Windows, Cocoa on macOS, QT or GTK on Linux and Kivy for Android.

- [swallow-pywebview](https://github.com/rangwea/swallow-pywebview)： Base on [pywebview](https://pywebview.flowrl.com/) using Python，the frontend base on [alpinejs](https://alpinejs.dev/) and [tailwindcss](https://tailwindcss.com/)。

Somehow related, I've been using pywebview for some internal tools: https://github.com/r0x0r/pywebview

Probably not as full-featured as Electronjs, but since we have a bunch of python scripts to convert to desktop apps, it's very useful.

I've been on a blitz experimenting with pywebview (electron but for Python) and a ReactJS UI.

The native mode uses pywebview under the hood which has libs for running on several platforms. Pyinstaller will pull these dependencies in. If you want more info on which platforms are supported by pywebview, check this directory: https://github.com/r0x0r/pywebview/tree/master/webview/lib

For reference to anyone not familiar - https://github.com/r0x0r/pywebview

import webview window = webview.create_window('Woah dude!', 'https://pywebview.flowrl.com') webview.start()

pywebview (https://github.com/r0x0r/pywebview) is an excellent suggestion and is already being used in NiceGUI to create a native desktop window with "native=True" option (see http://127.0.0.1:8080/documentation#ui_run).

Thanks for sharing. The issue is tracked at https://github.com/zauberzeug/nicegui/issues/576. But it looks like something which originates from the pywebview lib which is used to provide the native mode.
