chatbot_server: Chat-bot server logic (per-module)

In shidashi: A Shiny Dashboard Template Modular System with Chat Bot Support

Chat-bot server logic (per-module)

Description

Sets up the chat server for a single module. Creates its own Chat object, binds tools from the ⁠MCP⁠ session registry, and manages per-module conversation history.

The function renders chatbot_ui() into the drawer's uiOutput via shiny::renderUI, and opens the drawer when a "button.click" shidashi-event with type = "open_drawer" is received. Any element with data-shidashi-action="shidashi-button" data-shidashi-type="open_drawer" can trigger the drawer.

This function is injected into each module's server function by modules.R when agents.yaml has enabled: yes. It is called inside shiny::moduleServer(), so session is module-scoped. shinychat operations use the scoped session; only drawer and event operations use session$rootScope().

Usage

chatbot_server(
  input,
  output,
  session,
  id = "shidashi-chatbot",
  drawer_id = "shidashi_drawer",
  agent_conf = NULL
)

Arguments

input, output, session	Standard Shiny server arguments (typically module-scoped when inside moduleServer).
id	character; must match the id used in chatbot_ui(). Default "shidashi-chatbot".
drawer_id	character; the output ID of the drawer's uiOutput placeholder (from module_drawer()). Default "shidashi_drawer".
agent_conf	list; parsed agents.yaml content. Used for the system prompt and tool configuration.

Value

Called for side effects (sets up observers). Returns invisible(NULL).
