Retrive id from meteor insert inside callback

1

Hi guys,

I’m trying to retrive the id of an insert inside a Meteor Method inside a callback

Server:

Meteor.method({
   longMethod: function (item) {
       externalApiCall(item, function(err, result) {
           return CollectionName.insert({result});
       });
   }
});

Client:

 Meteor.call('longMethod', item, function(err, insertID) {
     Flowrouter.go('dynamicPath', insertID);
});

this obviously doesn’t work, because it’s returning in the wrong place. How can retrieve the id of a successful insert nested in a callback?

Should I use a reactive variable? how?

You could consider wrapping the server-side external async call in Meteor.wrapAsync.

Meteor.method({
  longMethod: function (item) {
    const wrappedExternalApiCall = Meteor.wrapAsync(externalApiCall);
    try {
      return wrappedExternalApiCall(item);
    } catch (err) {
      throw new Meteor.Error('oops', 'something bad happened');
    }
  }
});

the situation actually is even worse:

Meteor.method({
   longMethod: function (item) {
       externalApiAuth(credentials, function(err, result) {
              result.externalApiCall(item, function (err, result) {
                     return CollectionName.insert({result});

              })});
                  });
   }
});

can I wrapAsync multiple times?

p.s.: how do you color your code in discourse? :smiley:

Well, what you really mean here is:

Meteor.methods({
  longMethod: function(item) {
    const wrappedExternalApiAuth = Meteor.wrapAsync(externalApiAuth);
    const wrappedExternalApiCall = Meteor.wrapAsync(externalApiCall);
    try {
      wrappedExternalApiAuth(credentials);
      const result = wrappedExternalApiCall(item);
      return CollectionName.insert({ result });
    } catch (err) {
      throw new Meteor.Error('oops'), 'something bad happened'
    }
  }
});

P.S. use backticks:
