title: Build React app generate static files with chunk suffix
body: <p>I have create a react app using below command
  npx create-react-app my-app</p>
  
  <p>Now when I am building the app for production using below command
  npm run build </p>
  
  <p>It generate below files with suffix. </p>
  
  <p><code>build\static\js\1.82dafdb5.chunk.js</code>
  <code>build\static\js\runtime~main.229c360f.js</code>
  <code>build\static\js\main.a27c0d6d.chunk.js</code>
  <code>build\static\css\main.c2586263.chunk.css</code></p>
  
  <p>I am looking how can i avoid random number and chunk suffix  in file name. And is there any way to only have one js file so that instead of importing three js files I can have one js file to import.</p>
