Azure storage javascript client: how to track upload progress using Ionic/Angular?

javier 936 Reputation points

Following this guideline sample-blob.html I want to track upload progress by getting the progress value to the DOM. I also want to print, say, 'done' in the DOM when the upload is finished. Is there a way to "subscribe" to SpeedSummary so I can get its progress value? Any other more recommended approach?

My code:

var finishedOrError = false;  
      var speedSummary = blobService.createBlockBlobFromBrowserFile('input-data', filename, file, {blockSize : customBlockSize}, function(error, result, response) {  
        finishedOrError = true;  
        if (error) {  
            // Upload blob failed  
            alert('Problema: Volver a intentar o contactar al administrador');  
        } else {  
            // Upload successfully  
            alert('Subida Exitosa');  
            return result;  
      speedSummary.on('progress', function () {  
        var process = speedSummary.getCompletePercent();  
      var finish_upload = function(){  
        //TODO set upload finish process  
        //this.isUploading = false; DOESN'T WORK SINCE this is speedSummary in this context  
      var displayProcess = function(process){  
        //TODO set progress indicator  

Note: I am aware of this implementation upload-to-azure-blob-storage-with-angular-7977e979496a but it gives me an error when implementing the uploadFile function. But more importantly I am looking for something more straigthforward to implement.
