title: How can I run a build of React app?
body: <p>I did a build for a React app using <code>npm run-script build</code> and I need to run it. Using <code>npm run webpack</code> is returning an error. Excuse my being very new to React but I really need to know how to run this app. I hope you can help! </p>
