Invoke npm scripts upon file changes. Configure via package.json using glob patterns.

$ npm install rerun-script --save-dev

usage

Usage: rerun-script [options]

Options:

  -a, --automatic              run tests automatically
  -h, --help                   output usage information
  -V, --version                output the version number
  -d, --directory [directory]  package directory

configure package.json

  • NOTE 1: While the examples below use the standard lint checker, you are free to use any lint checker you like.
  • NOTE 2: The watch script in package.json is optional and is only necessary if you plan to invoke rerun-script via npm run. You can use any script name you like.

package.json

compact (recommended) format:
{
    "scripts": {
        "test": "node test.js",
        "lint": "standard",
        "watch": "rerun-script"
    },

    "watches": {
        "test": [ "*.js", "lib/**/*.js", "test/**/*.js" ],
        "lint": [ "*.js", "lib/**/*.js", "test/**/*.js" ]
    }
}
verbose format:
{
    "scripts": {
        "test": "node test.js",
        "lint": "standard",
        "watch": "rerun-script"
    },

    "watches": [
        {
            "script": "test",
            "patterns": [ "*.js", "lib/**/*.js", "test/**/*.js" ]
        },
        {
            "script": "lint",
            "patterns": [ "*.js", "lib/**/*.js", "test/**/*.js" ]
        }
    ]
}

If you only have one pattern to match for a script, you can pass in a string instead of an array:

{
    "scripts": {
        "test": "node test.js",
        "lint": "standard",
        "watch": "rerun-script"
    },

    "watches": {
        "test": "test/**/*.js",
        "lint": "*.js"
    }
}

start the watcher

# directly
$ ./node_modules/.bin/rerun-script

# or via `npm run watch`
$ npm run watch
