title: Web API Call in Standalone React App Generating a CORS error
body: <p>I have a project that is only a frontend, built with React, in which I am trying to make a call to an external API when an LI is clicked. Here is my code for one of my components. I took out the actual url from this snippet because it is very long, but the call works when using Postman.</p>
  
  <pre><code>getPlayerStats(name) {
      fetch(url)
          .then(function(response) {
              return response.resultSets.rowSet
          })
  }
  </code></pre>
  
  <p>This produces this error in my browser console: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. </p>
  
  <p>Any help on this issue? Most of the info I've read has suggestions for things to do on the backend, but my project does not have a backend. Thanks!</p>
