Run a server

This is a convenience function that provides a simple way to call startServer, service, and stopServer in the correct sequence. It does not return unless interrupted or an error occurs.

runServer(host, port, app, interruptIntervalMs = NULL)

Arguments

host

A string that is a valid IPv4 or IPv6 address that is owned by this server, which the application will listen on. "0.0.0.0" represents all IPv4 addresses and "::/0" represents all IPv6 addresses.

port

A number or integer that indicates the server port that should be listened on. Note that on most Unix-like systems including Linux and macOS, port numbers smaller than 1024 require root privileges.

app

A collection of functions that define your application. See startServer.

interruptIntervalMs

Deprecated (last used in httpuv 1.3.5).

Details

If you have multiple hosts and/or ports to listen on, call the individual functions instead of runServer.
