I'm using Meteor, what do I need to do to wait for a promise to be returned from an API call?

Question

if (Meteor.isClient) {

  Template.hello.events({
    \'click input\': function () {

      //create a new customer
      Meteor.call(\'createCustomer\', function (e

Another approach is to use Futures. I use this a lot on the server side to wait for results to return back to the client.

Here's a small example of that I use for logins:

Accounts.login(function (req, user) {
    var Future = Npm.require("fibers/future");
    var fut = new Future();
    HTTP.call("POST", globals.server + 'api/meteor-approvals/token',
        {
            timeout: 10000, followRedirects: true,
            headers: {
                'Content-Type': 'application/x-www-form-urlencoded'
            },
            params: {
                username: userName,
                password: req.password
            }},
        function (err, result) {
            if (err) {
                logger.error("Login error: " + err);
                fut.throw(err);
            }
            else {
                fut.return("Success");
            }
        }
    );
    return fut.wait();
}
