Installation

pip install shinywidgets, plus one extra for each widget library you use.

shinywidgets needs Python 3.10 or newer.

pip install shinywidgets

That installs the core: @render_widget, output_widget(), and everything that connects a widget to your app. It doesn’t install any widget library. Each one is an optional extra, so you only pull in what you use:

pip install 'shinywidgets[plotly]'

An extra installs the widget library plus anything shinywidgets needs to work with it. Every widget’s guide shows its install command near the top (here’s plotly’s). To install several at once, separate them with commas:

pip install 'shinywidgets[plotly,itables]'

Deploying an app? List the same extras in its requirements.txt; see Deployment. If a widget doesn’t show up, see Troubleshooting.
