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


node-supervisor -?

Node Supervisor is used to restart programs when they crash.
It can also be used to restart programs when a *.js file changes.

Usage: supervisor [options] supervisor [options] -- [args ...]

Required: The program to run.

Options: -w|--watch A comma-delimited list of folders or js files to watch for changes. When a change to a js file occurs, reload the program Default is '.'

-i|--ignore A comma-delimited list of folders to ignore for changes. No default

--ignore-symlinks Ignore symlinks :)

-s|--timestamp Log timestamp after each run. Make it easy to tell when the task last ran.

-p|--poll-interval How often to poll watched files for changes. Defaults to Node default.

-e|--extensions A comma-delimited list of file extensions to watch for changes. Default is 'node,js' (or when CoffeeScript, 'node,js,coffee,litcoffee').

-x|--exec The executable that runs the specified program. Default is 'node'

-pid|--save-pid Save supervisor's process id to a file at the given path.

--debug[=port] Start node with --debug flag.

--debug-brk[=port] Start node with --debug-brk flag.

--harmony Start node with --harmony flag.

--inspect[=port] Start node with --inspect flag.

-n|--no-restart-on error|exit|success Don't automatically restart the supervised program if it ends. Supervisor will wait for a change in the source files. If "error", an exit code of 0 will still restart. If "exit", no restart regardless of exit code. If "success", no restart only if exit code is 0.

-t|--non-interactive Dissable interactive capacity With this option, supervisor won't listen to stdin

--force-watch Use instead of fs.watchFile. This may be useful if you see a high cpu load on a windows machine.

-k|--instant-kill Instantly kills the server process, instead of gracefully shutting down the server. This can be useful when the node app has events attached to SIGTERM or SIGINT so as to do a graceful shutdown before the process exits.

-RV|--restart-verbose Logs the file(s) that caused supervisor to restart

-h|--help|-? Display these usage instructions.

-q|--quiet Suppress DEBUG messages

Options available after start: rs - restart process. Useful when you want to restart your program even if no file has changed.

Examples: supervisor myapp.js supervisor supervisor -w scripts -e myext -x myrunner myapp supervisor -w lib,server.js,config.js server.js supervisor -- server.js -h host -p port

In order to not watch for file changes, use "-i .".
