fileapi

FileAPI — a set of javascript tools for working with files. Multiupload, drag'n'drop and chunked file upload. Images: crop, resize and auto orientation by EXIF.

A set of javascript tools for working with files.

Download the files from the dist directory, and then:

    <div>
        <!-- "js-fileapi-wrapper" -- required class -->
        <div class="js-fileapi-wrapper upload-btn">
            <div class="upload-btn__txt">Choose files</div>
            <input id="choose" name="files" type="file" multiple />

    <script>window.FileAPI = { staticPath: '/js/FileAPI/dist/' };</script> 
    <script src="/js/FileAPI/dist/FileAPI.min.js"></script> 
    <script>
        var choose = document.getElementById('choose');
        FileAPI.event.on(choose, 'change', function (evt){
            var files = FileAPI.getFiles(evt); // Retrieve file list
 
            FileAPI.filterFiles(files, function (fileinfo/**Object*/){
                if( /^image/.test(file.type) ){
                    return  info.width >= 320 && info.height >= 240;
                }
                return  false;
            }, function (files/**Array*/rejected/**Array*/){
                if( files.length ){
                    // Make preview 100x100 
                    FileAPI.each(files, function (file){
                        FileAPI.Image(file).preview(100).get(function (errimg){
                            images.appendChild(img);
                        });
                    });
 
                    // Uploading Files 
                    FileAPI.upload({
                        url: './ctrl.php',
                        files: { images: files },
                        progressfunction (evt){ /* ... */ },
                        completefunction (errxhr){ /* ... */ }
                    });
                }
            });
        });
    </script> 

Edit the file crossdomain.xml and place it to the root of the domain to which files will be uploaded.

    <script>
        window.FileAPI = {
              debug: false   // debug mode, see Console

                // Default: object[foo]=1&object[bar][baz]=2 
                // .NET: https://github.com/mailru/FileAPI/issues/121#issuecomment-24590395 
                return  name + (idx != null ? '['+ idx +']' : '');
            }
        };
    </script>

        window.FileAPI = { /* options */ };
        require(['FileAPI'], function (FileAPI){
            // ... 
        });
    </script> 

Retrieve file list from input element or event object, also support jQuery.

  • input — HTMLInputElement, change and drop event, jQuery collection or jQuery.Event
var el = document.getElement('my-input');
FileAPI.event.on(el, 'change', function (evt/**Event*/){
    // Retrieve file list 
    var files = FileAPI.getFiles(el);
 
    // or event 
    var files = FileAPI.getFiles(evt);
});

Get info of file (see also: FileAPI.addInfoReader).

  • file — file object (https://developer.mozilla.org/en-US/docs/DOM/File)
  • callback — function, called after collected info of file
// Get info of image file (FileAPI.exif.js included) 
FileAPI.getInfo(file, function (err/**String*/info/**Object*/){
    if( !err ){
        console.log(info); // { width: 800, height: 600, exif: {..} } 
    }
});
 
// Get info of mp3 file (FileAPI.id3.js included) 
FileAPI.getInfo(file, function (err/**String*/info/**Object*/){
    if( !err ){
        console.log(info); // { title: "...", album: "...", artists: "...", ... } 
    }
});

Filtering the list of files, with additional information about files. See also: FileAPI.getInfo and FileAPI.addInfoReader.

  • files — original list of files
  • filter — function, takes two arguments: file — the file itself, info — additional information.
  • callback — function: list — files that match the condition, other — all the rest.
// Get list of file 
var files = FileAPI.getFiles(input);
 
// Filter the List 
FileAPI.filterFiles(files, function (file/**Object*/info/**Object*/){
    if( /^image/.test(file.type) && info ){
        return  info.width > 320 && info.height > 240;
    } else {
        return  file.size < 20 * FileAPI.MB;
    }
}, function (list/**Array*/other/**Array*/){
    if( list.length ){
        // .. 
    }
});

Get a list of files, including directories.

  • evt — drop event
  • callback — function, takes one argument, a list of files
FileAPI.event.on(document, 'drop', function (evt/**Event*/){
    evt.preventDefault();
 
    // Get a list of files 
    FileAPI.getDropFiles(evt, function (files/**Array*/){
        // ... 
    });
});

Uploading files to the server (successively). Returns XHR-like object. It is important to remember to correctly worked flash-transport server response body must not be empty, for example, you can pass, just text "ok".

var el = document.getElementById('my-input');
FileAPI.event.on(el, 'change', function (evt/**Event*/){
    var files = FileAPI.getFiles(evt);
    var xhr = FileAPI.upload({
        url: 'http://rubaxa.org/FileAPI/server/ctrl.php',
        files: { file: files[0] },
        completefunction (errxhr){
            if( !err ){
                var result = xhr.responseText;
                // ... 
            }
        }
    });
});

Adds a handler for the collection of information about a file. See also: FileAPI.getInfo and FileAPI.filterFiles.

  • mime — pattern of mime-type
  • handler — takes two arguments: file object and complete function callback
FileAPI.addInfoReader(/^image/, function (file/**File*/callback/**Function*/){
    // http://www.nihilogic.dk/labs/exif/exif.js 
    // http://www.nihilogic.dk/labs/binaryajax/binaryajax.js 
    FileAPI.readAsBinaryString(file, function (evt/**Object*/){

            var oFile = new BinaryFile(binaryString, 0, file.size);
            var exif  = EXIF.readFromBinaryFile(oFile);
            callback(false, { 'exif': exif || {} });
        }
        else if( evt.type == 'error' ){
            callback('read_as_binary_string');
        }

HTML5 borwser support

This cross-origin resource sharing is used to enable cross-site HTTP requests.

Drag'n'drop events support.

Availability Flash plugin.

Canvas support.

Support dataURI as src for image.

Support chuncked upload.


Flash is very "buggy" thing :] The server response can not be empty. Therefore, in the event of a successful uploading http status should be only 200 OK.

Flash settings. It is advisable to place flash on the same server where the files will be uploaded.

<script>
    var FileAPI = {

Client and server communicate to each other using the following HTTP headers and status codes.
Client explicitly sets the following headers:

  • Content-Range: bytes <start-offset>-<end-offset>/<total>
  • Content-Disposition: attachment; filename=<file-name>
Any other headers are set by a target browser and are not used by client. Library does not provide any facilities to track a file uniqueness across requests, it's left on developer's consideration.
Response codes:
  • 200 - last chunk is uploaded
  • 201 - chunk is successfully saved
  • 416 - range is not acceptable error, recoverable
  • 500 - server error, recoverable
For recoverable errors server tries to resend chunk `chunkUploadRetry` times then fails.
  • X-Last-Known-Byte: int, library tries to resend chunk from the given offset. Applicable to response codes 200 and 416
  • All the other codes - fatal error, user's involvement is recommend.
