title: Fetch API await chunk of defined chunk size
body: <p>I want to fetch an URL and process the response in chunks of a defined size. I also don't want to block while waiting for the whole chunk to be available. Is something like this available in the Fetch API?</p>
  <p>Example how it could look like:</p>
  <pre class="lang-js prettyprint-override"><code>const response = await fetch(url)
  const reader = response.body.getReader()
  const chunk = await reader.read(CHUNK_SIZE) 
  
  </code></pre>
