Node - Bluemix Object Storage

Question

I wanted to try Object Storage with my Bluemix account.

The frontend is sending me image in base64 encoding.

I wanted to know how I can store a file (by writing a new temporary one), and upload it on Object Storage?

I successfully uploaded a file by giving path in a parameter, but here I only have base64 data.

Does someone have a point to start?

Thank you

Use the Object Storage Node SDK:

https://github.com/ibm-bluemix-mobile-services/bluemix-objectstorage-serversdk-nodejs

Or you could use pkgcloud too:
