Right now, the Firebase documentation guides you on uploading files to Firebase Storage by using their JavaScript library. 

I am operating a server without NodeJS installed. Is it possible to upload files like image, audio, through the Firebase REST API? 

At the moment I am using curl in a bash script to send JSON. I would prefer not to store base64 encoding in a database field, I want the file to be stored in a folder inside the Storage section. 

Storage folder shown below:
