Hi everyone! I’m in the process of wrapping the phonegap-nfc Cordova plugin for Ionic/Angular. I’m trying to wrap it in a promise-based interface, and have the gist of the idea. However, many of these functions are of the form: function(callback, success, error)
. How would you promisify this to be in Angular/Ionic/ngCordova standards? I’ve been looking through the currently done plugins but haven’t found anything.
Check out this plugin example
var q = $q.defer();
In this example, you can see how the callbacks for errors and success and handled with promises
Thanks for the response! I should have been a bit more specific. Here’s an example of the code I’m wrapping:
Currently, I’m doing
addTagDiscoveredListener: function(callback) {
var d = $q.defer();
$window.nfc.addTagDiscoveredListener(callback,
function(message) {
d.resolve(message);
},
function(err) {
d.reject(err);
}
);
return d.promise;
}
I’m pretty new to Angular, and attaching an event listener to the document without going through Angular seems like a bad way to go about things. Is there some better method?
$window.addEventListener
$document.addEventListener
Either of these should work, plus it will be handled though angular
Awesome. Thanks so much!
