httpuv (version 1.3.3)

service: Process requests

Description

Process HTTP requests and WebSocket messages. Even if a server exists, no requests are serviced unless and until service is called.

Usage

service(timeoutMs = ifelse(interactive(), 100, 1000))

Arguments

timeoutMs

Approximate number of milliseconds to run before returning. If 0, then the function will continually process requests without returning unless an error occurs.

Details

Note that while service is waiting for a new request, the process is not interruptible using normal R means (Esc, Ctrl+C, etc.). If being interruptible is a requirement, then call service in a while loop with a very short but non-zero Sys.sleep during each iteration.

Examples

while (TRUE) {
  service()
  Sys.sleep(0.001)
}
