I couuldn’t find an appropriate category - can we have a “Tips” category?

Anyway, I found a really helpful example of the use of Meteor.wrapAsync the other day, and it helped me with what I was trying to do - here’s the gist:

meteor-wrapAsync.js

// Thanks @trusktr
var requestSync = Meteor.wrapAsync(function(url, callback) {
  request(url, function(error, response, body) {
    callback(error, {response: response, body: body})
  })
});

var result = requestSync("http://google.com");

console.log(result.response, result.body);

The NPM library I was using had three parameters in its callback function - so I wrote it the above way, and it worked!

Hope that helps!
