Answer 1

use the min.js files in production or bundle your application code with process.env.NODE_ENV === 'production' and you should be good to go!

Answer 2

As of version 15.2, production React error messages (NODE_ENV=production) now include a URL that you can visit where you can see the original, unobfuscated error.

You should consider upgrading to React 15.2 in order to get access to these error messages. Additionally, some production crash reporting tools automatically unminify these errors for you.

Answer 3

If your package.json scripts has dll， try exec npm run dll or yarn run dll.

Answer 4

Have you check the DOM element that you are trying render ? I had this error before due to a silly mistake. The worst part is bundle was minified. The element id is not same

Index.html

<div id="ds-app"></div>

app.jsx

React.DOM.render(<App/>, document.getElementById('app'))
