Lightweight Angular JS directive to upload files. Features:

• File upload for HTML5 and non HTML5 browsers with Flash polyfill. Allows client side validation before uploading the file.
• Sends the file with regular angular $http (with shim for non-HTML5 browsers) so all angular $http features are available.
• Supports upload progress
• Supports cancel/abort upload while in progress
• Supports File drag and drop
• All non-HTML5 code is in a separate shim file so you can easily remove it if you only supports HTML5.
• Flash FileAPI will be loaded on demand so it won't add extra load for HTML5 browsers.
• You can configure $http method to be either POST or PUT for HTML5 browsers.

HTML:

<script src="angular.file-upload-shim.min.js"></script> <!--only needed if you support upload progress/abort or non HTML5 FormData browsers.-->
<!-- NOTE: angular.file-upload-shim.js MUST BE PLACED BEFORE angular.js-->
<script src="angular.min.js"></script>
<script src="angular-file-upload.min.js"></script> <!--place after angular.js-->

<div ng-controller="MyCtrl">
  <input type="text" ng-model="myModelObj">
  <input type="file" ng-file-select="onFileSelect($files)" >
  <input type="file" ng-file-select="onFileSelect($files)" multiple>
  <div ng-file-drop="onFileSelect($files)" ng-file-drag-over-class="optional-css-class"
        ng-show="dropSupported">drop files here</div>
  <div ng-file-drop-available="dropSupported=true" 
        ng-show="!dropSupported">HTML5 Drop File is not supported!</div>
  <button ng-click="upload.abort()">Cancel Upload</button>
</div>

JS:

//inject angular file upload directives and service.
angular.module('myApp', ['angularFileUpload']);

var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
  $scope.onFileSelect = function($files) {
    //$files: an array of files selected, each file has name, size, and type.
    for (var i = 0; i < $files.length; i++) {
      var $file = $files[i];
      $scope.upload = $upload.upload({
        url: 'server/upload/url', //upload.php script, node.js route, or servlet url
        // method: POST or PUT,
        // headers: {'headerKey': 'headerValue'}, withCredential: true,
        data: {myObj: $scope.myModelObj},
        file: $file,
        //(optional) set 'Content-Desposition' formData name for file
        //fileFormDataName: myFile,
        progress: function(evt) {
          console.log('percent: ' + parseInt(100.0 * evt.loaded / evt.total));
        }
      }).success(function(data, status, headers, config) {
        // file is uploaded successfully
        console.log(data);
      })
      //.error(...).then(...); 
    }
  }
}];

Note: angular.file-upload-shim.js must be loaded before angular.js and is only needed if you are supporting non-HTML5 FormData browsers or you need the support for upload progress or cancel.

For browsers not supporting HTML5 FormData (IE8, IE9, ...) FileAPI module is used. For these browsers these two files are needed: FileAPI.min.js, FileAPI.flash.swf which will be loaded if the browser does not supports HTML5 FormData (no extra load for HTML5 browsers). Note: Flash needs to be installed on the client browser since FileAPI uses Flash to upload files.

You can put these two files beside angular-file-upload-shim(.min).js on your server to be loaded automatically on demand or use the following script to set the FileAPI load path (optional):

<script>
    //optional needs to be loaded before angular-file-upload-shim(.min).js
    FileAPI = {
        jsPath: '/js/FileAPI.min.js/folder/',
        staticPath: '/flash/FileAPI.flash.swf/folder/'
    }
</script>
<script src="angular.file-upload-shim.min.js"></script>...

The module is registered at bower with the name angularjs-file-upload (notice 'js' after angular):

bower install angularjs-file-upload

You can find the sample server code in Java/GAE here.

If you use this module you can give it a thumbs up at http://ngmodules.org/modules/angular-file-upload.
