node.js - how to automatically restart a node server? -

we finishing development of project, client using errors occur - crashing server.

i know register service 'upstart' script on linux, in order have node service restart when crashes.

but our server running other stuff, can't restart it. well, actually, while writing, realize have 2 questions then:

• will 'upstart' work without having reboot? whispering yes me :)
• if not, other option have 'respawn' node server when crashes?

yes, upstart restart process without reboot.

also, should forever.
