JarCastingangular-file-upload
Lightweight Angular JS directive to upload files.
See the DEMO page
Table of Content:
- File upload for
HTML5andnon-HTML5browsers with Flash polyfill FileAPI. Allows client side validation before uploading the file - Uses regular
$httpto upload (with shim for non-HTML5 browsers) so all angular$httpfeatures are available - Supports upload progress
- Supports cancel/abort upload while in progress
- Supports File drag and drop (HTML5 only)
- Supports Directory drag and drop (webkit only)
- Supports CORS
- All
non-HTML5code is in a separate shim file and could be easily removed if you only supportsHTML5. (html5-shim.js is needed forprogressevent though) - Flash
FileAPIwill be loaded on demand fornon-HTML5FormData browsers so no extra load forHTML5browsers. $uploadmethod can be configured to be eitherPOSTorPUTfor HTML5 browsers.$upload.http()enables progress event for angular httpPOST/PUTrequests. You can upload file content with theContent-Typeof the file to CouchDB, imgur, etc... forHTML5FileReaderbrowsers. See #88(comment) for discussion and usage.
HTML:
<!-- shim is needed to support upload progress/abort for HTML5 and non-HTML5 FormData browsers.-->
<!-- use html5-shim.js instead if you just support HTML5 browsers and you need progress event-->
<!-- Note: shim.js MUST BE PLACED BEFORE angular.js and angular-file-upload.js AFTER angular.js-->

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: {'header-key': 'header-value'},
//withCredentials: true,
data: {myObj: $scope.myModelObj},
file: file, // or list of files ($files) for html5 only
//fileName: 'doc.jpg' or ['1.jpg', '2.jpg', ...] // to modify the name of the file(s)
// customize file formData name ('Content-Desposition'), server side file variable name.
//fileFormDataName: myFile, //or a list of names for multiple files (html5). Default is 'file'
// customize how data is added to formData. See #40#issuecomment-28612000 for sample code
//formDataAppender: function(formData, key, val){}
}).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(success, error, progress);
// access or attach event listeners to the underlying XMLHttpRequest.
//.xhr(function(xhr){xhr.upload.addEventListener(...)})
}
/* alternative way of uploading, send the file binary with the file's content-type.
Could be used to upload files to CouchDB, imgur, etc... html5 FileReader is needed.
It could also be used to monitor the progress of a normal http post/put request with large data*/
// $scope.upload = $upload.http({...}) see 88#issuecomment-31366487 for sample code.
};

Order of scripts: 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 to support upload progress or cancel.
Upload multiple files: Only for HTML5 FormData browsers (not IE8-9) if you pass an array of files to file option it will upload all of them together in one request. In this case the fileFormDataName could be an array of names or a single string. For Rails or depending on your server append square brackets to the end (i.e. file[]). If you want a cross browser approach you need to iterate through files and upload them one by one like the code above. This is due to the limitation of Flash file upload.
$upload.http(): You can also use $upload.http() to send the file binary or any data to the server while being able to listen to progress event. See #88 for more details. This equivalent to angular $http() but allow you to listen to progress event for HTML5 browsers.
Rails progress event: If your server is Rails and Apache you may need to modify server configurations for the server to support upload progress. See #207
drag and drop styling: For file drag and drop, ng-file-drag-over-class can be a function that returns a class name based on the $event. See the demo for a sample. If the attribute is not specified by default the element will have "dragover" class on drag over which could be used to style the drop zone. You can also specify ng-file-drag-over-delay to fix css3 transition issues from dragging over/out/over #277.
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 for example if you are using CDN (optional):
<script>
//optional need to be loaded before angular-file-upload-shim(.min).js
FileAPI = {
//only one of jsPath or jsUrl.
jsPath: '/js/FileAPI.min.js/folder/',
jsUrl: 'yourcdn.com/js/FileAPI.min.js',
//only one of staticPath or flashUrl.
staticPath: '/flash/FileAPI.flash.swf/folder/',
flashUrl: 'yourcdn.com/js/FileAPI.flash.swf',
//forceLoad: true, html5: false //to debug flash in HTML5 browsers
}
</script>
<script src="angular-file-upload-shim.min.js"></script>...
Old browsers known issues:
- Because of a Flash limitation/bug the server needs to send a response body in order for the success and error callbacks to work properly. See 163#issuecomment
- Custom headers will not work due to a Flash limitation #111 #224 #129
- Due to Flash bug #92 Server HTTP error code 400 will be returned as 200 to the client. So avoid returning 400 on your server side for upload response otherwise it will be treated as a success response on the client side.

Download latest release from here or if you are using bower
#notice 'ng' at the beginning of the module name not 'angular'
bower install ng-file-upload
Make sure to load the scripts in your html file exactly in this order as described in the Usage:
<script src="angular-file-upload-shim(.min).js"></script>
<script src="angular(.min).js"></script>
<script src="angular-file-upload(.min).js"></script>
Or for yeoman with bower automatic include:
bower install ng-file-upload -save
bower install ng-file-upload-shim -save
bower.json
{
"dependencies": [..., "ng-file-upload-shim", "angularjs", "ng-file-upload", ...],
}
