Function returning before async method done Node JS

Question

I currently have a function that is called from my router:

router.js:

var result = Api.getUser();

console.log(\"Result: \" + result);

Answer 1

Promises are awesome, I would suggest looking into them. However, a simple callback will do the trick

api:

exports.getUser = function(req, result, callback) {
  request.get({
    uri: URL + '/user/me/',
    headers: {Authorization: 'bearer ' + req.user.accessToken},
    json: true
  }, function(e, r, body) {
        if(e) {
            callback({error: true});
        } else {
            callback(body)
        }
    });
};

router:

var result
Api.getUser(req, result, function (response) {
  result = response
  console.log(result)
});
