Run and restart npm commands after emit file webpack builds
This is simple webpack plugin that monitors webpack events and start or restart npm/yarn command. The main purpose of this plugin is to restart node process when webpack has finised rebuilding the source tree. It is also possible to wait for the marker to make sure the process is finished doing the job (like starting the web server)
Use NPM:
npm i daemon-command-webpack-plugin -D
or npm install daemon-command-webpack-plugin --save-dev
Use YARN:
yarn add daemon-command-webpack-plugin --dev
// package.json
{
"name": "me-app",
"version": "1.0.0",
"scripts": {
"start:dev:env": "node server/build/index.js",
"start:dev": "NODE_ENV=development PORT=3000 node server/build/index.js",
},
}
// webpack.config.js
import DaemonCommandPlugin from 'daemon-command-webpack-plugin';
module.exports = {
// ... rest of config
plugins: [
// Command #1
new DaemonCommandPlugin('start:dev:env', {
spawn : {
env : {
NODE_ENV : 'development',
PORT : 3000
}
}
}),
// Command #2
new DaemonCommandPlugin('start:dev');,
// Command #3 use yarn
new DaemonCommandPlugin('start:dev', {
manager : 'yarn'
});
]
}
// webpack.config.js
import DaemonCommandPlugin from 'daemon-command-webpack-plugin';
module.exports = {
// ... rest of config
plugins: [
// Command #1
new DaemonCommandPlugin('start:dev', {
marker : true
});
]
}
// your-app.js
import express from 'express';
import marker from 'daemon-command-webpack-plugin/marker';
let app = express();
app.listen(8080, () => {
console.log('Listen port: 8080');
marker();
// or
marker('Listen port: 8080'); // Custom message
})
