title: No React warnings when using next.js
body: <p>When using nextjs I never get react warnings like: your map function is missing a key or your useEffect is missing a dependency. With cra i always get those and i find them helpful but next shows something else. Here's an image of what i see in Next.<a href="https://i.stack.imgur.com/yoaQ9.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yoaQ9.png" alt="enter image description here" /></a></p>
  <pre><code>useEffect(() =&gt; {
      if (selectedTheme &amp;&amp; selectedCategory) {
          client
              .get(`/films?category=love&amp;theme=sacrifice`)
              .then(res =&gt; console.log(res));
      }
  }, [selectedTheme]);
  </code></pre>
  <p>as you can see my effect is missing a dep.</p>
