title: Deploy create-react-app on Google App Engine
body: <p>I'm trying to deploy my app created using <a href="https://github.com/facebook/create-react-app" rel="noreferrer">create-react-app</a> on Google App Engine.</p>
  
  <p>My app works well on local (both <code>npm start</code> and <code>npm run build &amp; serve -s build</code>).
  However, the deployed app on Google App Engine shows only the index.html, and does not call my react code.</p>
  
  <p>The Chrome Developer Console is showing <code>Uncaught SyntaxError: Unexpected token &lt;</code>.</p>
  
  <p>Also, I found on console.cloud.google.com that the deployed app did not include the build folder. Is this correct?</p>
  
  <p>Anyone can solve this problem?</p>
  
  <p>Here is my package.json:</p>
  
  <pre><code>{
    "name": "XXXXX",
    "version": "0.1.0",
    "private": true,
    "dependencies": {
      "react": "^16.8.2",
      "react-dom": "^16.8.2",
      "react-ga": "^2.5.7",
      "react-router-dom": "^4.3.1",
      "react-scripts": "2.1.5"
    },
    "scripts": {
      "start": "react-scripts start",
      "build": "react-scripts build",
      "test": "react-scripts test",
      "eject": "react-scripts eject"
   },
    "eslintConfig": {
      "extends": "react-app"
    },
    "browserslist": [
      "&gt;0.2%",
      "not dead",
      "not ie &lt;= 11",
      "not op_mini all"
    ]
  }
  </code></pre>
  
  <p>Also, here is my app.yaml.</p>
  
  <pre><code>runtime: nodejs10
  
  handlers:
  - url: /.*
    static_files: build/index.html
    upload: build/index.html
  - url: /
    static_dir: build
  </code></pre>
