    npm install mini-deferred --save
    var $def = require('mini-deferred');

    Usage $def method

    var promise = $def(function(resolve,reject,notify){
            $.ajax({
               url : "/api",
               success : function(data){
                  //do something
                  resolve(data);
               },
               error : reject,
               progress : notify
            })
    });
     
    promise.then(function(data){
       //do something with success data
       return data + "Some new data";
    },function(err){
        //handle error
    },function(value){
        //display progress
    })
    //chain promises
    .then(function(data){
       //do something else with success data
       return data + "Some new data";
    },function(err){
        //handle error
    },function(value){
        //display progress
    })

    var defer = $def.defer();
    $.ajax({
           url : "/api2",
           success : function(data){
              //do something
              defer.resolve(data);
           },
           error : defer.reject,
           progress : defer.notify
        })
     
    var promise2 = defer.promise();

    Doing something after multiple promise $def.when()

      $def.when(promise,promise2).then(function(data){
        //data will be arry of resolve data
        //[promise 1 resolve data, promise 2 resolve data]
      },function(err){
        //handle error
      })

    promise.then()

    promise.then(onSuccess,onError,onProgress);

    promise.done()

    promise.done(onSuccess);

    promise.fail()

    promise.fail(onError);

    promise.progress()

    promise.progress(onProgress);

    promise.always()

    promise.always(function(data){
      // comes here whether it's success or fail
    });

    promise.state() // return state of promise
