Why is React Webpack production build showing Blank page?

use

import { HashRouter } from 'react-router-dom';

instead of

import { BrowserRouter} from 'react-router-dom';

and don't forget to replace it in your routes code

<HashRouter>
  ...
</HashRouter>

Changing

import {BrowserRouter as Router} from 'react-router-dom'

to:

import {HashRouter as Router} from 'react-router-dom'

in App.js helped me fix the same issue in my create-react-app project.

I figured it out, I was using browserHistory without setting up a local server. If i changed it to hashHistory it worked. To test webpack production locally with react-router browser history i needed to do this Configure a Server:

Your server must be ready to handle real URLs. When the app first loads at / it will probably work, but as the user navigates around and then hits refresh at /accounts/23 your web server will get a request to /accounts/23. You will need it to handle that URL and include your JavaScript application in the response.

An express app might look like this:

const express = require('express')
const path = require('path')
const port = process.env.PORT || 8080
const app = express()

// serve static assets normally
app.use(express.static(__dirname + '/public'))

// handle every other route with index.html, which will contain
// a script tag to your application's JavaScript file(s).
app.get('*', function (request, response){
  response.sendFile(path.resolve(__dirname, 'public', 'index.html'))
})

app.listen(port)
console.log("server started on port " + port)

And just in case anyone is deploying to firebase using react-router with browser-history do this:

{
  "firebase": "<YOUR-FIREBASE-APP>",
  "public": "<YOUR-PUBLIC-DIRECTORY>",
  "ignore": [
    "firebase.json",
    "**/.*",
    "**/node_modules/**"
  ],
  "rewrites": [
    {
      "source": "**",
      "destination": "/index.html"
    }
  ]
}
