title: How do I support IE 11 with Create React App 3.0?
body: <p>With the release of Create React App 3.0 and the addition of browserlist, adding support for IE 11 is trivial, but the steps can be hard to find if you don't know where to look. The documentation lists "Supported Browsers" and shows the default browserslist configuration ( <a href="https://facebook.github.io/create-react-app/docs/supported-browsers-features" rel="noreferrer">https://facebook.github.io/create-react-app/docs/supported-browsers-features</a> ) but that isn't all you need to know.</p>
  
  <p>Checking browserl.ist with the production settings you'll see IE 11 has greater usage than Edge still ( <a href="https://browserl.ist/?q=%3E0.2%25%2C+not+dead%2C+not+op_mini+all" rel="noreferrer">https://browserl.ist/?q=%3E0.2%25%2C+not+dead%2C+not+op_mini+all</a> ) With a default CRA 3 app you'll get Syntax Error in main.chunk.js and other errors in your app with IE 11.</p>
