Set fields of a Vue component from the server

Source: R/vue_server.R
update_vue.Rd

The Vue layer's update*Input(): assigns fields of a component's state – its data, or what its setup() returned, or a vue_store()'s – and the component, and every template showing them, follow. As with Shiny's updaters, the component's value is reported back to input$<id> afterwards.

Usage

update_vue(session = shiny::getDefaultReactiveDomain(), id, ..., value = NULL)

Arguments

session

Shiny session; the current one by default, as for shiny::updateTextInput().

id

The component's id (un-namespaced).

...

Fields to set, <field> = <value>. A function is JS().

value

The component's value: sets whichever field its input names.

Value

Called for its side effect; returns NULL invisibly.

Examples

if (interactive()) {
  # inside a server function
  update_vue(id = "counter", value = 0)
  update_vue(id = "cart", note = "Free delivery today")
}
