Overview

shinyGovstyle integrates GOV.UK Design System components into R Shiny. It aims to make it easier for government analysts to develop production-ready dashboards that users find intuitive and can trust.

The GOV.UK Design System component documentation remains the authoritative reference for all components, including detailed guidance of when, how, and when not(!) to use each of the components.

Note: Using accessible components does not replace the need for comprehensive accessibility testing of the combination you put together in your own specific application.

We welcome feedback and contributions:

See it in action

The quickest way to get a feel for what is available is the example showcase app, which demonstrates the full range of components:

Online: department-for-education.shinyapps.io/shinygovstyle-example-app
Local (after installing the package): shinyGovstyle::run_example()

The source code for the example app lives in inst/example_app/ and is a useful reference for how components fit together in a real multi-page app using Shiny modules.

Installation

Install the latest stable release from CRAN:

install.packages("shinyGovstyle")

To use the latest development version directly from GitHub:

pak::pak("dfe-analytical-services/shinyGovstyle")

shinyjs dependency

Some components require shinyjs to be loaded in your UI. Add shinyjs::useShinyjs() anywhere in your UI when using:

error_on() / error_off() — inline field-level error toggling
word_count() — live character and word counting on text inputs
cookieBanner() — GOV.UK cookie consent banner

ui <- bslib::page_fluid(
  shinyjs::useShinyjs(),
  # rest of your UI
)

A minimal working app

The skeleton below shows the components that appear on every page of a shinyGovstyle app. It uses bslib, which is generally recommended for building responsive apps with R Shiny.

library(shiny)
library(shinyGovstyle)

ui <- bslib::page_fluid(
  skip_to_main(),
  header(
    org_name = "My department",
    service_name = "My dashboard"
  ),
  banner(
    inputId = "phase",
    type = "Beta",
    label = "This is a new service."
  ),
  gov_main_layout(
    gov_row(
      gov_box(
        size = "two-thirds",
        heading_text("Welcome", size = "l", level = 1),
        gov_text("Select a report from the navigation above.")
      )
    )
  ),
  footer()
)

server <- function(input, output, session) {}

shiny::shinyApp(ui, server)

For a more complete example - including multi-page navigation, footer links, and the server logic to wire it all together - see the complete example at the end of the Layout options vignette.

Component overview

Page structure and layout

All page-level components (header(), footer(), banner(), skip_to_main(), service_navigation(), cookieBanner()) and the content grid system (gov_main_layout(), gov_row(), gov_box()) are covered in the Layout options vignette.

Headings and text

Styled headings, body text, lists, callouts, external links, notification banners, and typography are covered in the Headings and text vignette.

Form inputs

text_input(), text_area_input(), select_input(), checkbox_input(), radio_button_Input(), date_Input(), file_Input(), button_Input(), and download_button() provide GOV.UK-styled equivalents of standard Shiny form controls; values are read from input$<inputId> in the server in the usual way.

Interactive components

accordion() and govTabs() provide collapsible panels and tabbed interfaces with full keyboard navigation and ARIA support built in.

Error handling

error_summary() produces a GOV.UK error summary panel that lists all validation errors at the top of the page; error_on() and error_off() toggle inline field-level error messages on any input. These require shinyjs::useShinyjs() in the UI, see shinyjs dependency for more details.

Data display

govTable() and govReactable() render data tables with GOV.UK styling; value_box() displays a headline figure with a label, suited to summary statistics at the top of a dashboard.
