grunt-supervisor

Run supervisor as a grunt task for easy configuration and integration with the rest of your workflow.

This Grunt task is freely inspired from the grunt-nodemon by Chris Wen.

Getting Started

If you haven't used grunt before, be sure to check out the Getting Started guide, as it explains how to create a gruntfile as well as install and use grunt plugins. Once you're familiar with that process, install this plugin with this command:

npm install grunt-supervisor --save-dev

Then add this line to your project's Gruntfile.js gruntfile:

grunt.loadNpmTasks( "grunt-supervisor" );

The "todo" task

In your project's Gruntfile, add a section named supervisor to the data object passed into grunt.initConfig().

Minimal usage

The minimal usage of grunt-supervisor runs with a script specified:

supervisor: {
  target: {
    script: "index.js"
  }
}

Usage with all available options

supervisor: {
  target: {
    script: "index.js",
    options: {
      args: [ "dev" ]
      watch: [ "bin" ],
      ignore: [ "test" ],
      pollInterval: 500,
      extensions: [ "js,jade" ],
      exec: "node",
      debug: true,
      debugBrk: true,
      harmony: true
      noRestartOn: "exit",
      forceWatch: true,
      quiet: true,
      async: true
    }
  }
}

Required property

script

Type: String

Script that supervisor runs and restarts when changes are detected.

Options

The following options corresponds to the available options from supervisor. If you don't pass these options to the grunt tasks, the default values of supervisor will be used.

args

Type: Array of Strings
List of arguments to be passed to your script.

watch

Type: Array of Strings
List of folders or js files to watch for changes.

ignore

Type: Array of Strings
List of folders to ignore for changes.

pollInterval

Type: Number of milliseconds
How often to poll watched files for changes.

extensions

Type: Array of Strings
List of file extensions to watch for changes.

exec

Type: String
The executable that runs the specified script.

debug

Type: Boolean
Starts node with --debug flag.

debugBrk

Type: Boolean
Starts node with --debug-brk flag.

harmony

Type: Boolean
Starts node with --harmony flag.

noRestartOn

Type: String, "error" or "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.

forceWatch

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

quiet

Type: Boolean
Suppress DEBUG messages

async

Type: Boolean
Keeps Grunt from exiting. Set to false if there is another task like "watch" folowing this one.
