Add splash screen to teal application.

Usage

ui_teal_with_splash(
  id,
  data,
  title = build_app_title(),
  header = tags$p(),
  footer = tags$p()
)

srv_teal_with_splash(id, data, modules, filter = teal_slices())

Arguments

id

(character(1)) module id

data

(teal_data or teal_data_module) For constructing the data object, refer to teal_data() and teal_data_module().

title

(shiny.tag or character(1)) The browser window title. Defaults to a title "teal app" with the icon of NEST. Can be created using the build_app_title() or by passing a valid shiny.tag which is a head tag with title and link tag.

header

(shiny.tag or character(1)) The header of the app.

footer

(shiny.tag or character(1)) The footer of the app.

modules

(teal_modules) object containing the output modules which will be displayed in the teal application. See modules() and module() for more details.

filter

(teal_slices) Specifies the initial filter using teal_slices().

Value

Returns a reactive expression containing a teal_data object when data is loaded or NULL when it is not.

Details

This module pauses app initialization pending delayed data loading. This is necessary because the filter panel and modules depend on the data to initialize.

teal_with_splash follows the shiny module convention. init() is a wrapper around this that assumes that teal it is the top-level module and cannot be embedded.

Note: It is no longer recommended to embed teal in shiny apps as a module. but rather use init to create a standalone application.
