title: removing params in url for nextjs redirect
body: <p>I have the code below. It redirects to /home and passes a email var. However, in the address bar, it shows http://localhost:4000/home?email=steverodgers@gmail.com. How can I pass variables using react and next.js cleanly?</p>
  <pre><code>import { withRouter } from 'next/router'
  authenticateUser(this.user)
          .then(response =&gt; {
            var email = response['email'];
  
            if (email) {
              this.props.router.push({
                pathname: '/home',
                query: { email: email}
              });
            }
        });
  </code></pre>
