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.
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] <program>
supervisor [options] -- <program> [args ...]
Required:
<program>
The program to run.
Options:
-w|--watch <watchItems>
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 <ignoreItems>
A comma-delimited list of folders to ignore for changes.
No default
-p|--poll-interval <milliseconds>
How often to poll watched files for changes.
Defaults to Node default.
-e|--extensions <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 <executable>
The executable that runs the specified program.
Default is 'node'
--debug
Start node with --debug flag.
--debug-brk
Start node with --debug-brk flag.
--harmony
Start node with --harmony flag.
-n|--no-restart-on error|exit
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.
--force-watch
Use fs.watch instead of fs.watchFile.
This may be useful if you see a high cpu load on a windows machine.
-h|--help|-?
Display these usage instructions.
-q|--quiet
Suppress DEBUG messages
Examples:
supervisor myapp.js
supervisor myapp.coffee
supervisor -w scripts -e myext -x myrunner myapp
supervisor -w lib,server.js,config.js server.js
supervisor -- server.js -h host -p port
Just run:
npm install supervisor -g
Get this code, and then do this:
