# Overview
This article collects a few small but more cohesive example apps that bring
together the package surfaces described elsewhere in the documentation.
The goal is not to present production-ready applications. Instead, these
examples show how the generated wrappers, curated Shiny bindings, layout
helpers, and command/browser-glue tools fit together in practice.
This small executed example prints the page scaffold emitted by a compact
`webawesomePage()` composition:
```{r examples-executed}
library(shiny.webawesome)
example_page <- webawesomePage(
title = "Example preview",
wa_container(
class = "wa-stack",
wa_badge("Preview"),
wa_card("Small executable example")
)
)
cat(as.character(example_page), sep = "\n")
```
# Example 1
## A simple dashboard-style page
This example uses `webawesomePage()`, `wa_container()`, and a handful of generated
components to assemble a compact page with a little structure and visual
hierarchy.
```{r example-layout, eval = FALSE}
library(shiny)
library(shiny.webawesome)
ui <- webawesomePage(
title = "Project overview",
wa_container(
class = "wa-stack",
style = "max-width: 32rem; margin: 2rem auto;",
wa_badge("Preview"),
wa_card("Status: active"),
wa_button(
"refresh",
"Refresh",
appearance = "outlined",
style = "width: 10rem;"
),
wa_card("Recent activity")
)
)
server <- function(input, output, session) {}
shinyApp(ui, server)
```
This is a good pattern when you want a page built primarily from generated
wrappers, with a small amount of package-level layout structure.
# Example 2
## A binding-focused interaction panel
This example combines a few bound components and displays the resulting Shiny
state directly.
```{r example-bindings, eval = FALSE}
library(shiny)
library(shiny.webawesome)
ui <- webawesomePage(
title = "Binding example",
wa_container(
class = "wa-stack",
style = "max-width: 36rem; margin: 2rem auto;",
wa_select(
"favorite_letter",
wa_option("A", value = "a"),
wa_option("B", value = "b"),
wa_option("C", value = "c")
),
wa_switch("notifications_enabled", "Notifications"),
wa_tree(
"navigation_tree",
selection = "multiple",
wa_tree_item("Section A", id = "section_a"),
wa_tree_item("Section B", id = "section_b"),
wa_tree_item("Section C", id = "section_c")
),
verbatimTextOutput("state")
)
)
server <- function(input, output, session) {
output$state <- renderPrint({
list(
favorite_letter = input$favorite_letter,
notifications_enabled = input$notifications_enabled,
navigation_tree = input$navigation_tree
)
})
}
shinyApp(ui, server)
```
This example is useful for understanding the package's semantic binding model:
the Shiny inputs reflect durable state rather than a raw browser event stream.
# Example 3
## A command-layer interaction example
This example uses generated components for the UI and the package's command
layer to drive browser-side behavior from the server.
```{r example-command, eval = FALSE}
library(shiny)
library(shiny.webawesome)
ui <- webawesomePage(
title = "Command example",
wa_container(
class = "wa-stack",
style = "max-width: 36rem; margin: 2rem auto;",
actionButton("open_dialog", "Open dialog"),
actionButton("show_details", "Show details"),
wa_dialog(
"dialog",
label = "Example dialog",
"Dialog body"
),
wa_details(
"details",
summary = "More information",
"Details body"
)
)
)
server <- function(input, output, session) {
observeEvent(input$open_dialog, {
wa_call_method("dialog", "show", session = session)
})
observeEvent(input$show_details, {
wa_call_method("details", "show", session = session)
})
}
shinyApp(ui, server)
```
This is a good pattern when the generated wrapper surface is sufficient for UI
construction, but the server still needs to trigger a specific browser-side
method directly.
