Running the Demo

git clone
npm install
npm start

and open http://localhost:3333/ in the browser

Instantiating the Media Platform in the Server

First, if you haven't done so yet, register at Wix Media Platform, create your organization, project and application.

var MediaPlatform = require('media-platform-js-sdk').MediaPlatform;
var mediaPlatform = new MediaPlatform({
    domain: '<As appears in the application page>',
    appId: '<As appears in the application page>',
    sharedSecret: '<As appears in the application page>'

Instantiating the Media Platform in the Browser

<script src="/media-platform.min.js">
var mediaPlatform = new MP.MediaPlatform({
    domain: '<As appears in the application page>',
    authenticationUrl: '<your authentication url - see example below>'

Authentication URL Node.js (with express) example:

 * Your own authentication mechanism comes here
app.get('/media-platform/auth-header', function (req, res, next) {
     * @description by default, the header authenticates the application
     * @type {{Authorization}}
    var header = mediaPlatform.getAuthorizationHeader();

File Upload


var UploadFileRequest = require('media-platform-js-sdk').file.UploadFileRequest;
* Only required for streams and buffers
var uploadRequest = new UploadFileRequest().setMimeType('image/jpeg');
mediaPlatform.uploadFile('/path', '<ReadStream || Buffer || string path to file>', uploadRequest || null, function (error, response) {
    if (error) {
        console.error('upload failed: ' + error.message);
    console.log('upload successful: ' + response);


<form id="upload-form" enctype="multipart/form-data" action="" method="post" target="upload-result">
    <input id="file" name="file" type="file">
<button id="upload-button">Upload</button>
    var fileUploadButton = document.getElementById('upload-button');
    var file = document.getElementById('file');
    var path = file.value.split("\\").pop();
    fileUploadButton.addEventListener('click', function() {
        mediaPlatform.fileManager.uploadFile(path, file)
            .on('upload-success', function(response) {
                 // do something 
            .on('upload-error', function(error) {
                 // do something 

Image Consumption

The SDK provides a programmatic facility to generate image URLs

var Image = require('media-platform-js-sdk').Image;
* The Image constructor accepts a FileDescriptor, FileMetadata or URL  
var image = new Image(fileDescriptor);
var url = image.crop(200, 200).toUrl('http://<image host>').url;

File Management

Wix Media Platform exposes a comprehensive set of APIs tailored for the management of previously uploaded files.

var fileManager = mediaPlatform.fileManager;

List files in a directory

var ListFilesRequest = require('media-platform-js-sdk').file.ListFilesRequest;
var listFilesRequest = new ListFilesRequest()
fileManager.listFiles('/directory', listFilesRequest, callback);

Get file metadata (by id)

fileManager.getFileMetadataById('fileId', callback);

Delete file

fileManager.deleteFileById('fileId', callback);
fileManager.deleteFileByPath('/path/to/file.txt', callback);
