Bootswatch + Bootstrap 5 themes for Shiny.

Here are just three of the 25 themes in shinyswatch:

Minty	Sketchy	Superhero

Installation

pip install shinyswatch

To install the latest development version from this repository:

pip install https://github.com/rstudio/py-shinyswatch/tarball/main

Usage

To use a theme, add a shinyswatch.theme theme object to your App’s UI definition.

# Minty theme
shinyswatch.theme.minty

# Sketchy theme
shinyswatch.theme.sketchy

# Superhero theme
shinyswatch.theme.superhero

Example Shiny application:

from shiny import App, Inputs, Outputs, Session, render, ui

import shinyswatch

app_ui = ui.page_fluid(
    ui.input_slider("num", "Number:", min=10, max=100, value=30),
    ui.output_text_verbatim("slider_val"),
    theme=shinyswatch.theme.darkly,  # <- Use a shinyswatch theme here
)


def server(input: Inputs, output: Outputs, session: Session):
    @output
    @render.text
    def slider_val():
        return f"{input.num()}"


app = App(app_ui, server)

Note: When writing shiny apps that use shinyswatch on shinylive.io, remember to add shinyswatch to your requirements.txt file!

Theme picker

To add a theme picker to your app, add the theme picker UI and server functions to your app’s UI and server definitions.
