An AppStructure object

Introduction

In examples, documentation, and code you might have seen a reference to an appStructure. An appStructure object is named a list() containing ShinyModule objects or nested lists containing ShinyModule objects. The structure of the appStructure list resembles how to navigate your shiny app, i.e:

library(DarwinShinyModules)

# Make some modules to make the `appStructure` with
base <- Text$new("**base**")
nested_a <- Text$new("**nested A**")
nested_b <- Text$new("**nested B**")
sub_a <- Text$new("**sub A**")
sub_b <- Text$new("**sub B**")
comb_a <- Text$new("**comb A**")
comb_b <- Text$new("**comb B**")
comb_c <- Text$new("**comb C**")

# Creating the `appstructure`
appStructure <- list(
 base = base,
 nested = list(nested_a, nested_b),
 nested_sub = list(
   sub_a = sub_a,
   sub_b = sub_b
 ),
 nested_combined = list(
   comb_a_b = list(comb_a, comb_b),
   comb_c = comb_c
 )
)

The main list() is always named, as for your navigation panel or bar, each items should have a name. Nested lists (see appStructure$nested) do not have to be named. The modules will be put underneath each other on the same page. If you do name the nested list (see appStructure$nested_sub), sub-items will be created for the main menu item.
