Shiny for python packages

iain · July 29, 2022, 7:28pm

Hi all,

Very stoked about the release of shiny for python. I am very new to python and I was wondering if there are any resources similar to GitHub - nanxstats/awesome-shiny-extensions: 🐝 Awesome R packages that offer extended UI or server components for the R web framework Shiny that would help me identify widgets that I could use in my apps.

In particular, I would love to find python widgets equivalents of

DT/reactable to display a table with filtering etc.
Shiny validate to validate user input
Waiter for loading screens etc

Thanks

Iain

Hi @iain, for the 1st item, try using qgrid via shinywidgets:

github.com

rstudio/py-shinywidgets/blob/6b6042/examples/outputs/app.py#L70-L121


      
          @output(id="qgrid")
          @render_widget
          def _():
              import qgrid
          
          
    randn = np.random.randn
              df_types = pd.DataFrame(
                  {
                      "A": pd.Series(
                          [
                              "2013-01-01",
                              "2013-01-02",
                              "2013-01-03",
                              "2013-01-04",
                              "2013-01-05",
                              "2013-01-06",
                              "2013-01-07",
                              "2013-01-08",
                              "2013-01-09",
                          ],

Currently we don't have "1st class" solutions for the other 2 items, but it doesn't seem like porting relevant projects over to python would be very difficult.

Thanks @cpsievert, qgrid looks like a great alternative to DT based on the demo app in the third link you shared.

Regarding shiny validate, I can't speak highly enough about how impactful this package has been at improving the UX of the apps that I build at my company. It is the type of feedback interaction every user expects of an app.

In case it is of interest, ipydatagrid also looks like a promising DT like widget - GitHub - bloomberg/ipydatagrid: Fast Datagrid widget for the Jupyter Notebook and JupyterLab developed by one of the maintainers of ipywidgets

itables is a python widget for DT and I have created a suggestion issue for support at py-shinywidgets.
