Clustering with Pm2 and HapiJS

[ThiagoMiranda]

Hello..
I don't know if this is the right place to question these but since it's a popular repository probably someone here encounter this very issue of mine.

Basically I've turned the app into a Hapijs app using the HapiJS webpack plugin. It's a very straightforward plugin and I use it like this:

/** Register plugin and start server **/
let hapiPlugins = [{
		register: HapiSwagger,
		options: swaggerOptions
	},{
		register: Inert
	},{
		register: Vision
	},{
		register: WebpackPlugin,
		options: './webpack.config.js'
	},
	AuthCookie,
	Bell
];

let webpackPlugin = {};

/** Register plugin and start server **/
server.register(hapiPlugins);

So I've deployed my app in an ElasticBeanstalk t2.small machine using pm2 to run it:

"copy": "copyfiles -f ./src/favicon.ico ./dist"
"dist": "npm run copy & NODE_ENV=production ./node_modules/.bin/pm2 start bootstrap.js "

It's working very well ( it's a small app used internally at my company ) but I'm not sure if it's the best approach. Digging a little into pm2 I've discovered the option to cluster my application using the -i maxoption. I've putted it and it worked. But each child process built the same webpack files before launch so I have a peak on my processing and memory having, for example in my machine, 8 "webpack compile processes" running at the same time. Using pm2 I can tell which child is the master one so this is my question:

Is there any way to just run the webpack compiling process once? Basically all that I need is to get the files from the dist/folder independently of whom putted it there. Or am I doing a totally wrong approach?

Thanks for the attention,
Cheers
