title: add multiple proxy in package json
body: <p>I'm using two servers for my react app, one for express and the other one that come with create-react-app. So in the react side server in package.json I added :</p>
  <pre><code>&quot;proxy&quot;: {
      &quot;/auth/google&quot;: {
        &quot;target&quot;: &quot;http://localhost:5000&quot;
      }
    },
  </code></pre>
  <p>I run the server and I got this error :</p>
  <pre><code>When specified, &quot;proxy&quot; in package.json must be a string.
  Instead, the type of &quot;proxy&quot; was &quot;object&quot;.
  Either remove &quot;proxy&quot; from package.json, or make it a string.
  </code></pre>
  <p>How can I fix that ? How can I add proxy ? Maybe using other syntax ?</p>
