Can I run a Sails.js Service synchronously?

Question

I have a Sails.js Service that parses an RSS feed using the FeedParser package. The service takes a single RSS feed URL, parses it, creates an array of posts and returns the array. In my controller, this is what I have:

var stories = RssService.fetch(rssLinks[0]);
console.log(stories);

res.json({ stories: stories }, 200);

However, it looks like this is an asynchronous request and as a result, the console log says undefined and the response inside the JSON is null . How do I make it so that the script waits until the RssService returns posts before I console log?

Thank you.

Answer 1

Put a callback into your service. View comments above.

Controller

RssService.fetch(rssLinks[0], function(err,data){

  if(err) return next(err)
  return res.json({stories:data}, 200);

});
