Comparison-page server module

Server module powering the comparison page. Instantiates two [mod_plot_pti2_srv()] sub-modules (`first_leaf` / `second_leaf`) against the same shapes, structured PTI data, and weights. The two maps share inputs but render independently so the user can pan / zoom each side separately while comparing the same underlying weighting.

Usage

mod_pti_comparepage_newsrv(
  id,
  shp_dta,
  map_dta,
  wt_dta,
  active_tab,
  target_tabs,
  mtdtpdf_path = ".",
  shapes_path = ".",
  show_adm_levels = NULL,
  ...
)

Arguments

id

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

shp_dta

Reactive yielding a named list of `sf` tibbles (one per admin level). Forwarded to both [mod_plot_pti2_srv()] children.

map_dta

Reactive yielding the structured PTI list (output of [mod_ptipage_newsrv()]).

wt_dta

Reactive yielding the weights list (output of the weights-input module).

active_tab

Reactive character indicating the currently selected tab.

target_tabs

Character vector of tab names this module should render for.

mtdtpdf_path

Character. Filesystem path to the metadata PDF served via the side-panel download link in each map.

shapes_path

Character. Filesystem path to the shapes archive served via the side-panel download link in each map.

show_adm_levels

Character vector or NULL. Admin levels to expose in the side-panel selector of each map.

...

Forwarded to both [mod_plot_pti2_srv()] children.

Value

No explicit return value. Called for side effects (renders two side-by-side leaflet maps within the Shiny session).
