title: What are these '@' signs in Redux?
body: <p>I tried looking online related to redux or redux-actions which is used by the open source project, but I can't find out what the '@' is for (try searching for the @ sign, not too helpful):</p>
  
  <p><code>export const LIKE_POST = '@post/LIKE_POST';</code></p>
  
  <p>Can anyone shed some light? From the <a href="https://github.com/busyorg/busy/blob/develop/src/client/post/postActions.js" rel="nofollow noreferrer">busy</a> github (file linked to). I don't see anything mentioned in the <a href="https://redux-actions.js.org/api" rel="nofollow noreferrer">redux-actions</a> page either.</p>
  
  <p>Also, if you care to tell me how the dispatch to <code>LIKE_POST</code> is getting received anywhere, because that string <code>LIKE_POST</code> is not found in the <a href="https://github.com/busyorg/busy/blob/develop/src/client/post/postsReducer.js" rel="nofollow noreferrer">reducer file</a>, or anywhere else in the project.</p>
  
  <p>Thank you!</p>
