title: How to run npm start for reactjs even after closing terminal?
body: <p>I've been following facebook tutorial with reactjs</p>
  
  <p>I installed <code>npm install -g create-react-app</code> <a href="https://www.npmjs.com/package/react-scripts" rel="nofollow noreferrer">https://www.npmjs.com/package/react-scripts</a> and created the app with it</p>
  
  <p>But now I'm confuse how do I deploy my app to, for example, digital ocean? I know I can use <code>pm2</code> to run a node server but I don't see how does <code>npm start</code> works as it just runs this in the package.json</p>
  
  <pre><code>{
    "name": "hello-world",
    "version": "0.1.0",
    "private": true,
    "devDependencies": {
      "react-scripts": "0.7.0"
    },
    "dependencies": {
      "babel-preset-es2015": "^6.18.0",
      "babel-preset-react": "^6.16.0",
      "express": "^4.14.0",
      "mongoose": "^4.6.8",
      "react": "^15.3.2",
      "react-dom": "^15.3.2"
    },
    "scripts": {
      "start": "react-scripts start",
      "build": "react-scripts build",
      "test": "react-scripts test --env=jsdom",
      "eject": "react-scripts eject"
    }
  }
  </code></pre>
  
  <p><code>"start": "react-scripts start"</code> what is it actually starting there?</p>
  
  <p>also, it says that to build your app for deployment to use <code>npm run build</code> that just gives me a folder named <code>build</code> but I can't find anything to run <code>node</code> on.</p>
