shiny.webawesome

shiny.webawesome provides an R and Shiny interface to the Web Awesome component library.

The package is largely generated from the upstream Web Awesome metadata file custom-elements.json, which the package treats as the primary source of truth for component wrappers and related generated surface. It also bundles the Web Awesome runtime it needs, so package users do not need to install Web Awesome assets separately in their Shiny apps. To report the bundled Web Awesome version in your current installation, use wa_version().

The package design aims to stay as close as practical to upstream Web Awesome names, conventions, and component APIs, while adopting normal R naming conventions such as snake_case. Because Web Awesome lives in the browser and Shiny spans both server and client, the package also includes a curated set of Shiny bindings plus a narrow helper/command layer for cases where a pure wrapper mirror is not enough.

See the package documentation for the details of the generated wrapper surface, Shiny bindings, and advanced browser-glue helpers.

Installation

To install from CRAN, use either of the following:

install.packages("shiny.webawesome")

pak::pak("shiny.webawesome")

To install the development version from GitHub, use either of the following:

pak::pak("mbanand/shiny.webawesome")

remotes::install_github("mbanand/shiny.webawesome")

Usage

library(shiny)
library(shiny.webawesome)

ui <- webawesomePage(
  title = "shiny.webawesome",
  wa_container(
    class = "wa-stack",
    style = "max-width: 32rem; margin: 2rem auto;",
    wa_button(
      "example_button",
      "Click me",
      appearance = "filled",
      style = "width: 10rem;"
    ),
    wa_card("A simple card body")
  )
)

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

shinyApp(ui, server)

You can use shiny.webawesome in two ways:

• use individual Web Awesome components inside an ordinary Shiny page such as fluidPage()
• build the whole app page with webawesomePage()

If you only need a few components inside an otherwise ordinary Shiny app, using them inside fluidPage() is fine. The package attaches its runtime dependencies automatically in that case.

library(shiny)
library(shiny.webawesome)

ui <- fluidPage(
  h2("Mixed app"),
  wa_card(
    wa_badge("Beta", appearance = "filled"),
    "This app uses a few Web Awesome components inside fluidPage()."
  )
)

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

shinyApp(ui, server)

If Web Awesome is the main UI system for the app, prefer webawesomePage(). It attaches the package dependency once at page level and gives you a cleaner full-page Web Awesome setup.

When you mix Web Awesome components into fluidPage() or another Bootstrap layout, check the result in the browser. The components will work, but your app may still need light CSS review for spacing, typography, or theme/style mismatches between Bootstrap and Web Awesome.
