title: Reading product metafields through Shopify ScriptTag API
body: <p>I'm building a Shopify embedded application with two main points of functionality:</p>
  <ol>
  <li>Upon install, product meta fields are populated with some values</li>
  <li>Upon page load, a custom script is injected into product page through shopify ScriptTag api</li>
  </ol>
  <p>The injected script displays some icon alongside the values from product meta fields.</p>
  <p>Currently, from the product page, the injected script is having to request the meta fields from my local server, which then queries the clients shopify for before sending back the response.</p>
  <p>Is there a way to access the meta field values directly from the product page, without having to do the above?</p>
  <p>Thanks in advance.</p>
