node-supervisor

A little supervisor script for nodejs. It runs your program, and
watches for code changes, so you can have hot-code reloading-ish
behavior, without worrying about memory leaks and making sure you
clean up all the inter-module references, and without a whole new
require system.

Simple Install

Install npm, and then do this:

npm install supervisor

You don't even need to download or fork this repo at all.

Fancy Install

Get this code, install npm, and then do this:

	npm link .

1. Re-attach to a process by pid. If the supervisor is
   backgrounded, and then disowned, the child will keep running. At
   that point, the supervisor may be killed, but the child will keep
   on running. It'd be nice to have two supervisors that kept each
   other up, and could also perhaps run a child program.
2. Run more types of programs than just "node blargh.js".
3. Be able to run more than one program, so that you can have two
   supervisors supervise each other, and then also keep some child
   server up.
4. When watching, it'd be good to perhaps bring up a new child
   and then kill the old one gently, rather than just crashing the
   child abruptly.
5. Keep the pid in a safe place, so another supervisor can pull
   it out if told to supervise the same program.
6. It'd be pretty cool if this program could be run just like
   doing node blah.js, but could somehow "know" which files had
   been loaded, and restart whenever a touched file changes.
