Add JavaScript dependency to the UI of a Shiny app

Adds shinyOAuth's JavaScript so oauth_module_server() can redirect the browser and manage its temporary login cookie. This low-level helper supplies the browser dependency for custom HTTP integrations.

oauth_ui(), oauth_form_post_ui() and oauth_connections_ui() already include this dependency, callback handling and response headers.

Usage

use_shinyOAuth(inject_referrer_meta = TRUE)

Arguments

inject_referrer_meta

If TRUE (default), adds a meta tag to the page: an instruction asking the browser not to share the page's address when loading images, scripts, or other files. Some files may start loading before the browser reads this instruction. The UI wrappers also set the HTTP header, which applies from the start of page loading.

Value

A tagList that loads the browser code once.

Details

The UI wrappers process callbacks before rendering application HTML, redirect to a clean URL, and send Referrer-Policy: no-referrer, Cache-Control: no-store and Pragma: no-cache. A custom HTTP integration provides that handling separately. This dependency cannot set HTTP headers; its optional referrer meta tag takes effect only after the browser reads it.

Examples

# Low-level browser setup for a custom HTTP integration.
# Supply equivalent callback handling and response headers separately.
# For ordinary apps, use oauth_ui(ui, id = "auth", client = client).
ui <- shiny::fluidPage(
  use_shinyOAuth()
  # ...
)
