How to set contenttype on azure blob storage with nodejs

I've got a nodejs server, am using the azure-storage module and am trying to upload a wav file to azure blob storage.

I'm trying to set the contentType on the blob to 'audio/wav' but it is showing up in storage as 'application/octet-stream'. Code is:

upload: function (id, buffer, mimeType, callback) {
self = this;
var size = buffer.length;
var stream = streamifier.createReadStream(buffer);
var options = { contentType: 'audio/wav' };
self.blobService.createBlockBlobFromStream(self.containerName, id, stream, size, options, function (error, result, response) {
if (error) {

Any ideas as to what I'm doing wrong?

Answer Source

According the comments in source code at Github, the option architecture has changed, to define the contentType, please try to use following code snippet:

var options = {contentSettings:{contentType:'audio/wav'}}

Any further concern, please feel free to let me know.
