Titanium Appcelerator Alloy TiParseTestApp

![Alt text](Screen Shot 2014-05-24 at 8.52.34 PM.png?raw=true "Optional Title")

Sample application demonstrating the integration on Parse Javascript API with Titanium Appcelerator.

This example integrates Facebook account creation and the updating of the user account with information from the associated facebook account.

This utilizes the Parse-Appcelerator JavaScript Hack of Parse JavaScript SDK Version: 1.2.18

The challenge continues to make Parse work with Appcelerator but I have made so adjustment to the original hack I created to get the solution more fully integrated with Appcelerator and include Facebook integration in the solution.

It is the same basic premise as the original solution where we override existing objects in the parse library to leverage the Appcelerator HTTPClient and the Appcelerator Facebook integration. I have tested this solution with the integration IOS support for Facebook single sign on and with old way where you get the web UI for the login prompt.

Edits to the Parse Javascript API

Add this to line 1348 of Parse JavaScript SDK Version: 1.2.18

// Import Parse's local copy of underscore.
if (Titanium !== "undefined") {
  console.log("Using titanium");

  Parse._ = exports._.noConflict();
  exports.Parse = Parse;
} else

Replace line 8576 of Parse JavaScript SDK Version: 1.2.18

Parse.User._registerAuthenticationProvider(FB.provider);

Using your own configuration settings

Modify the config.json file to hold all the essential information, see example below

"global": {
    "parseOptions": {
        "facebookAppId": "",
        "applicationId": "",
        "javascriptkey": ""
    }
},

Then in your application index file

// values are  set in config
require('ti.parse_mine')(Alloy.CFG.parseOptions);

Accessing Titanium Facebook Object

If you pass in teh facebook id, the library will instaniate the Titanium Facebook object, which you must also include in your tiapp.xml. The Facebook object is available globally through the object TiFacebook

Uploading a File

File uploading is a little trick on Appcelerator because the javascript library cannot understand the filesystem

The way thus problem is addressed is by sending the file as a base64 string and then Parse will upload the file just fine.

An example here, assume I have an image from the camera in variable imageFromCamera that I want to save to Parse

// see code in next section
var photoService = require('photoService');
photoService.savePhoto({
   fileName : 'A New Image',
   media : imageFromCamera
}).then(function(_result){
  Ti.API.debug('_result: ' + JSON.stringify(_result, null, 2));
  alert('File Saved');
}, function(_error){ 
  alert("Error: " + error.code + " " + error.message);
});

We added some extra functionality in the photoService library. Since parse needs the file to be associated with an object, we create the object and associated the file with it all in one method.

We are using the Q promises library to keep the code manageble and avoid callback hell.

/**
 * 
 * @param {String} _options.fileName
 * @param {TiBlob} _options.media
 */
exports.savePhoto = function(_options) {
  var photoSource;
  var deferred = Q.defer();

  // CONVERT IMAGE SO PARSE IS HAPPY!!
  var b64 = Titanium.Utils.base64encode(_options.media);

  var file = new Parse.File(_options.fileName || "myfile.jpg", {
    base64 : b64.getText()
  });

  file.save().then(function(_result) {
    // The file has been saved to Parse.
    Ti.API.debug('_result: ' + JSON.stringify(_result, null, 2));

    // create object to associate file with
    var testObject = new Parse.Object("TestObject");

    // add file to object
    testObject.set("aFile", file);

    // save everything.. returns another promise
    return testObject.save();
  }).then(function(_result2) {
    Ti.API.info('_result2: ' + JSON.stringify(_result2, null, 2));
    deferred.resolve({
      success : true,
      model : _result2
    });
  }, function(error) {
    // The file either could not be read, or could not be saved to Parse.
    alert("Error: " + error.code + " " + error.message);
    Ti.API.error(JSON.stringify(error, null, 2));
    deferred.reject({
      error : error,
      msg : msg
    });
  });

  return deferred.promise;

};
