Webpack Hook Plugin

This plugin allows you to run any shell commands before or after webpack builds. This will work for both webpack and webpack-dev-server.

Goes great with running cron jobs, reporting tools, or tests such as selenium, protractor, phantom, ect.

Installation

npm install --save-dev webpack-hook-plugin

Setup

In webpack.config.js:

``js
import WebpackHookPlugin from 'webpack-hook-plugin';

module.exports = {
//...
//...
plugins: [
new WebpackHookPlugin({
onBuildStart:['echo "Webpack Start"'],
onBuildEnd:['echo "Webpack End"']
})
],
//...
}
`

Example

Insert into your webpack.config.js:

`js
import WebpackHookPlugin from 'webpack-hook-plugin';
const path = require('path');

var plugins = [];

plugins.push(new WebpackHookPlugin({
onBuildStart: ['echo "Starting"'],
onBuildEnd: ['python script.py && node script.js']
}));

var config = {
entry: {
app: path.resolve(__dirname, 'src/app.js')
},
output: {
path: path.resolve(__dirname, 'dist'), // regular webpack
filename: 'bundle.js'
},
devServer: {
contentBase: path.resolve(__dirname, 'src') // dev server
},
plugins: plugins,
module: {
loaders: [
{test: /\.js$/, loaders: 'babel'},
{test: /\.scss$/, loader: 'style!css!scss?'},
{test: /\.html$/, loader: 'html-loader'}
]
}
}

module.exports = config;

`
Once the build finishes, a child process is spawned firing both a python and node script.

* onBuildStart: array of scripts to execute on the initial build. Default: [ ]
* onBuildEnd: array of scripts to execute after files are emitted at the end of the compilation. Default: [ ]
onBuildExit: array of scripts to execute after webpack's process is complete. Note: this event also fires in webpack --watch when webpack has finished updating the bundle.* Default: [ ]
* onCompile: array of scripts to execute on every compile. Default: [ ]
* dev: switch for development environments. This causes scripts to execute once. Useful for running HMR on webpack-dev-server or webpack watch mode. Default: true
* safe`: switches script execution process from spawn to exec. If running into problems with spawn, turn this setting on. Default: false
