Wrapper server function for Shiny apps — server

Handles OAuth2 PKCE authentication flow with CSIAPPS, managing user tokens and info, and providing a consistent authentication status UI.

Usage

server_wrapper(app_specific_logic, sandbox = is_sandbox_mode())

app_specific_logic: Existing server logic of shiny web application
sandbox: If TRUE, the real OAuth2 redirect is skipped and the session is seeded from the developer's existing CSIAPPS_ACCESS_TOKEN, so a wrapped app can be run locally without client credentials. If no token is set, the app shell renders with an unauthenticated notice. Defaults to is_sandbox_mode(), which is TRUE by default. Disable it for deployment with options(csiapps.sandbox = FALSE) (or CSIAPPS_ENV=production) to use the real login flow. See csiapps-sandbox for details and limitations.

A Shiny server function that wraps the provided app-specific logic with authentication handling and user info retrieval.
