Check if a persistent browser session is active — browser_session

Verifies both the R-side flag and that Chrome is actually responsive by sending a lightweight evaluation to the browser. If Chrome has crashed or the websocket connection has been lost, the stale session is automatically cleaned up and FALSE is returned.

Usage

browser_session_active()

Value

Logical, TRUE if a session is active and responsive.

Examples

if (FALSE) { # \dontrun{
browser_session_active()  # FALSE
browser_session_start()
browser_session_active()  # TRUE
browser_session_close()
browser_session_active()  # FALSE
} # }
