1. I wrote this in webpack.config.js
entry: {
app: ['webpack-dev-server/client?http://localhost:8080','./app/js/app.js'],
vendor: ['jquery', 'bootstrap', 'angular', 'angular-ui-router', 'angular-ui-bootstrap']
}Introduction:
var app = angular.module('app', ['ui.router', 'ngGrid', 'ui.bootstrap']);2. Then the console reported an error 
What’s going on here?

Do you have any controllers under the "app" module? If yes, write it like this
so that the module can access the controller under the module
var app = angular.module('app', ['ui.router', 'ngGrid', 'ui.bootstrap','app-controller']);Referenced from stack overflow
