render_epoxy {epoxy}

Render Epoxy Output

Description

Server-side render function used to provide values for template items. Use named values matching the template variable names in the associated ui_epoxy_html() or ui_epoxy_mustache(). When the values are updated by the app, render_epoxy() will update the values shown in the app's UI.

Usage

render_epoxy(
  ...,
  .list = NULL,
  env = parent.frame(),
  outputFunc = ui_epoxy_html,
  outputArgs = list()
)

renderEpoxyHTML(..., env = parent.frame())

Arguments

...

Named values corresponding to the template variables created with the associated ui_epoxy_html() UI element.

.list

A named list or a shiny::reactiveValues() list with names corresponding to the template variables created with the associated ui_epoxy_html() UI element.

env

The environment in which to evaluate the ...

outputFunc

Either ui_epoxy_html() or ui_epoxy_mustache(), i.e. the UI function to be paired with this output. This is only used when calling render_epoxy() in an Shiny runtime R Markdown document and when you are only providing the output without an explicit, corresponding UI element.

outputArgs

A list of arguments to be passed through to the implicit call to ui_epoxy_html() when render_epoxy is used in an interactive R Markdown document.

Value

A server-side Shiny render function that should be assigned to Shiny's output object and named to match the .id of the corresponding ui_epoxy_html() call.

Functions

• renderEpoxyHTML(): Deprecated alias, please use render_epoxy().

Examples

# This small app shows the current time using `ui_epoxy_html()`
# to provide the HTML template and `render_epoxy()` to
# update the current time every second.

ui <- shiny::fluidPage(
	shiny::h2("Current Time"),
	ui_epoxy_html(
		"time",
		shiny::p("The current time is {{strong time}}.")
	)
)

server <- function(input, output, session) {
	current_time <- shiny::reactive({
		shiny::invalidateLater(1000)
		strftime(Sys.time(), "%F %T")
	})

	output$time <- render_epoxy(time = current_time())
}

if (rlang::is_interactive()) {
	shiny::shinyApp(ui, server)
}
