Performance module - server — mod_performance

Shows the change of every index over the period picked, from the summary of the Overview tab, so the histories are downloaded once for both tabs. The CSV file, named like performance-ytd-2026-11-07.csv, holds the changes of the chart from performance_data(), unrounded.

Usage

mod_performance_server(id, summary, indices, dark_mode)

Arguments

id: Character. Module namespace id, must match the id used in mod_performance_ui().
summary: Reactive returning the index_summary() of every index, as mod_overview_server() returns it.
indices: Data frame of indices from get_indices().
dark_mode: Reactive returning "light" or "dark", the mode of the app.

Value

None. Called for its side effect of registering the module server.
