I have a running React Application containing two routes

1. "/app"
2. "/dashboard" Also I have two entry points in webpack

entry: {
 a: 'browser.app.jsx',
 b: 'browser.dashboard.jsx'
}

I need to synchronize the routes with entry points. Like

Entry Point should be (a) again Route (1)

Entry point should be (b) against Route (2)

How can I achieve this functionality ?
