Nodemon Webpack Plugin

Uses Nodemon to watch and restart your module's output file, but only when webpack is in watch mode (ie, --watch).

Saves the need for installing, configuring and running Nodemon as a seperate process.

Installation

npm install nodemon-webpack-plugin --save-dev

Usage

const NodemonPlugin = require( 'nodemon-webpack-plugin' ) // Ding

module.exports = {
    entry: './src/server.js',
    output: {
        path: path.resolve('./dist'),
        filename: 'server.js',
    },
    plugins: [
        new NodemonPlugin(), // Dong
    ],
}

Then:

$ webpack --watch

Modes

Zero-config mode

new NodemonPlugin()

Only watches the output file.

With config

Allows a Nodemon config object to override and extend the default config:

{
    script: outputFile,
    watch:  outputFile,
}

For example:

new NodemonPlugin({
    /// Arguments to pass to the script being watched.
    args: ['demo'],

    // What to watch.
    watch: path.resolve('./dist'),

    // Files to ignore.
    ignore: ['*.js.map'],

    // Detailed log.
    verbose: true,

    // Node arguments.
    nodeArgs: [ '--debug=9222' ],

    // If using more than one entry, you can specify
    // which output file will be restarted.
    script: './dist/server.js',

    // Extensions to watch
    ext: 'js,njk,json'
})
