Why doesn't my react-routing work after webpack building?

Question

I made a simple react router. When I was developing it I was using npm start command which started a developing server. And everything were working. But when I built my app with command npm run build (using webpack), launched a simple http server and went to /add_project there is a 404 error. And I don't know why does it happen. Help please!

Here is the code:

App.js

imports...

render() {
    return (
        <Switch>
            <div>
                <Route exact path='/' component={Projects}/>
                <Route exact path='/add_project' component={AddProject} />
            </div>
        </Switch>
    );
}}

index.js

imports...

ReactDOM.render(
    <BrowserRouter>
        <App />
    </BrowserRouter>,
    document.getElementById('root')
);

webpack.config.js

const HtmlPlugin = require('html-webpack-plugin')

module.exports = {
  entry: './src',
  output: {
    filename: 'app.js',
    path: __dirname + '/dist'
  },
  devtool: 'source-map',
  module: {
    loaders: [{
      test: /\.js$/,
      exclude: /node_modules/,
      loader: 'babel-loader'
    }]
  },
  plugins: [
    new HtmlPlugin({
      template: 'public/index.html'
    })
  ]
}

UPD:

package.json

{
  "name": "Test",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "build": "webpack -p --progress --config webpack.config.js",
    "dev-build": "webpack --progress -d --config webpack.config.js",
    "test": "echo \"Error: no test specified\" && exit 1",
    "watch": "webpack --progress -d --config webpack.config.js --watch",
    "start": "react-scripts start"
  },
  "license": "MIT",
  "babel": {
    "presets": [
      "es2015",
      "react"
    ]
  },

    "react-router-dom": "^4.2.2",
    "style-loader": "^0.18.2",
    "webpack": "^3.11.0"
  }
}

UPD2:

AddProject.js

import React, { Component } from 'react';

class AddProject extends Component {
  constructor()
  {
    super();
  }

  render() {
    return (
      <form className="form-horizontal">
        <input type="text" ref="title" className="input" />
        <input type="text" ref=""/>
      </form>
    );
  }
}

export default AddProject;

Can you please post your `package.json` so we can see the scripts you are trying to run — wmash, Mar 02 '18 at 12:41
You can successfully go to the root path (`/`) and the correct page is displayed? — wmash, Mar 02 '18 at 12:52
Yes. But when i go to any other page and reload it, the 404 error displays — Ivan Gorsky, Mar 02 '18 at 12:58
Hmm, how are you serving the pages? Can you share your server-side code — wmash, Mar 02 '18 at 13:15
You mention that running this script is launching a node server. This server must be somehow serving the client pages. — wmash, Mar 02 '18 at 13:43
Looking into [this question](https://stackoverflow.com/questions/45122800/react-router-switch-behavior#45145372), do you mind attempting removing the `
`'s encapsulating the `Route`'s? — wmash, Mar 02 '18 at 14:13
@IvanGorsky, Did you got the solution? I'm getting same issue — Vipul Solanki, Mar 01 '19 at 13:07

You are already matching an exact path with '/' then matching it again with your /add_project route. Try changing

     <Route exact path='/add_project' component=
       {AddProject} />

To

      <Route path='/add_project' component=
       {AddProject} />

If exact is set on parent route the child route does not match, but 404 is rendered as expected
