Data-explorer page server module

Server module powering the data-explorer page. Computes the indicator list (excluding indicators tagged `fltr_exclude_explorer`), reshapes the metadata into per-admin explorer data, wires the variable selector (`mod_fltr_sel_var2_srv()`), the admin-level selector (`mod_get_admin_levels_srv()`), and the n-bins selector (`mod_get_nbins_srv()`). Defers map rendering until the host tab is opened (via `mod_first_open_count_server()`).

Usage

mod_dta_explorer2_server(
  id,
  shp_dta,
  input_dta,
  active_tab,
  target_tabs,
  mtdtpdf_path = NULL,
  shapes_path = NULL,
  data_path = NULL,
  expl_show_adm_levels = NULL,
  expl_default_adm_level = NULL,
  add_selected = reactive(NULL),
  ...
)

Arguments

id

Character. Shiny module namespace ID. Must match the `id` passed to [mod_dta_explorer2_ui()].

shp_dta

Reactive yielding a named list of `sf` tibbles, one per admin level.

input_dta

Reactive yielding the metadata list (output of [fct_template_reader()]).

active_tab

Reactive character indicating the currently selected tab.

target_tabs

Character vector of tab names this module should render for.

mtdtpdf_path, shapes_path, data_path

Character or `NULL`. Filesystem paths to the metadata PDF, shapes archive, and metadata xlsx served via the side-panel download links.

expl_show_adm_levels, expl_default_adm_level

Forwarded to `mod_get_admin_levels_srv()` (`show_adm_levels` and `default_adm_level`). Take precedence over the `explorer_*` Golem options.

add_selected

Reactive yielding character vector of indicator names to programmatically add to the variable picker (e.g. triggered by another tab). Defaults to `reactive(NULL)`.

...

Unused; retained for forward compatibility.

Value

A `reactive()` yielding `list(pre_map_dta, init_leaf)`. Other modules subscribing to the explorer's state read this reactive.
