Require error in app.js

I recently started working on a new game written in nodejs and for some reason its not letting me use require in the app.js which I know for a fact its possible because I made other games like this

This is the error I am recieving in my console on the website Uncaught ReferenceError: require is not defined at app.js:2

And this is the code its reffering too

var socket;
var pg = require('pg');

var config = require('../../config.json');

var conString = config.database.uri;

var client = new pg.Client(conString);
client.connect();

This error is hendering the rest of my code from running and im almost certain that this line

var config = require('../../config.json');

Will produce an error as well after i fix the first

According to webpack npm and all my other projects doing putting "build": "webpack" is supposed to allow require in app.js but its not working

Here is my package.json

  "description": "Placeholder",
  "main": "server/server.js",
