Build modern Shiny dashboards and applications using bslib (Bootstrap 5). Use when creating new Shiny apps, modernizing legacy apps (fluidPage, fluidRow/column, tabsetPanel, wellPanel, shinythemes), or working with bslib page layouts, grid systems, cards, value boxes, navigation, sidebars, filling layouts, theming, accordions, tooltips, popovers, toasts, or bslib inputs. Assumes familiarity with basic Shiny.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Modern Shiny Apps with bslib
Build professional Shiny dashboards using bslib's Bootstrap 5 components and layouts. This skill focuses on modern UI/UX patterns that replace legacy Shiny approaches.
## Quick Start
**Single-page dashboard:**
```r
library(shiny)
library(bslib)
ui <- page_sidebar(
title = "My Dashboard",
theme = bs_theme(version = 5), # "shiny" preset by default
sidebar = sidebar(
selectInput("variable", "Variable", choices = names(mtcars))
),
layout_column_wrap(
width = 1/3,
fill = FALSE,
value_box(title = "Users", value = "1,234", theme = "primary"),
value_box(title = "Revenue", value = "$56K", theme = "success"),
value_box(title = "Growth", value = "+18%", theme = "info")
),
card(
full_screen = TRUE,
card_header("Plot"),
plotOutput("plot")
)
)
server <- function(input, output, session) {
output$plot <- renderPlot({
hist(mtcars[[input$variable]], main = input$variable)
})
}
shinyApp(ui, server)
```
**Multi-page dashboard:**
```r
ui <- page_navbar(
title = "Analytics Platform",
theme = bs_theme(version = 5),
nav_panel("Overview", overview_ui),
nav_panel("Analysis", analysis_ui),

How to install
mdr add posit-dev/skills/shiny-bslib@sha256:d91977802bde3faeThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
