# 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), nav_panel("Reports", reports_ui) ) ``` ## Core Concepts ### Page Layouts - **`page_sidebar()`** -- Single-page dashboard with sidebar (most common) - **`page_navbar()`** -- Multi-page app with top navigation bar - **`page_fillable()`** -- Viewport-filling layout for custom arrangements - **`page_fluid()`** ...
