How to deploy a React App on Apache web server

Firstly, in your react project go to your package.json and adjust this line line of code to match your destination domain address + folder:

"homepage": "https://yourwebsite.com/your_folder_name/",

Secondly, go to terminal in your react project and type:

npm run build

Now, take all files from that newly created build folder and upload them into your_folder_name, with filezilla in subfolder like this:

public_html/your_folder_name

Check in the browser!

1. Go to your project root directory, e.g.: cd /home/ubuntu/react-js.
2. Build your project first: npm run build.
3. Check your build directory, all of the following files will be available in the build folder:

   asset-manifest.json
   favicon.ico
   manifest.json
   robots.txt
   static 
   assets
   index.html
   precache-manifest.ddafca92870314adfea99542e1331500.js 
   service-worker.js 

4. Copy the build folder to your apache server i.e /var/www/html:

   sudo cp -rf build /var/www/html

5. Go to sites-available directory:

   cd /etc/apache2/sites-available/

6. Open the 000-default.conf file:

sudo vi 000-default.conf and rechange the DocumentRoot path to /var/www/html/build.

7. Now go to the Apache configuration.

cd /etc/apache2

sudo vi apache2.conf

Add the following snippet:

<Directory /var/www/html>

       Options Indexes FollowSymLinks

       AllowOverride All

       Require all granted

</Directory>

8. Make a file inside /var/www/html/build:

   sudo vi .htaccess

Options -MultiViews
    
RewriteEngine On
    
RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule ^ index.html [QSA,L]

9. Restart Apache server:

   sudo service apache2 restart

Ultimately was able to figure it out , i just hope it will help someone like me.
Following is how the web pack config file should look like check the dist dir and output file specified. I was missing the way to specify the path of dist directory

const webpack = require('webpack');
const path = require('path');
var config = {
    entry: './main.js',

    output: {
        path: path.join(__dirname, '/dist'),
        filename: 'index.js',
    },

    devServer: {
        inline: true,
        port: 8080
    },
    resolveLoader: {
        modules: [path.join(__dirname, 'node_modules')]
    },
    module: {
        loaders: [
            {
                test: /\.jsx?$/,
                exclude: /node_modules/,
                loader: 'babel-loader',

                query: {
                    presets: ['es2015', 'react']
                }
            }
        ]
    },
}

module.exports = config;

Then the package json file

{
  "name": "reactapp",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack --progress",
    "production": "webpack -p --progress"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "react": "^15.4.2",
    "react-dom": "^15.4.2",
    "webpack": "^2.2.1"
  },
  "devDependencies": {
    "babel-core": "^6.0.20",
    "babel-loader": "^6.0.1",
    "babel-preset-es2015": "^6.0.15",
    "babel-preset-react": "^6.0.15",
    "babel-preset-stage-0": "^6.0.15",
    "express": "^4.13.3",
    "webpack": "^1.9.6",
    "webpack-devserver": "0.0.6"
  }
}

Notice the script section and production section, production section is what gives you the final deployable index.js file ( name can be anything )

Rest fot the things will depend upon your code and components

Execute following sequence of commands

npm install

this should get you all the dependency (node modules)

then

npm run production

this should get you the final index.js file which will contain all the code bundled

Once done place index.html and index.js files under www/html or the web app root directory and that's all.
