Basic utility functions, including,

• uploadS3File : { title : Text, data : [Byte]} -> Text
  • Upload a data to an S3 bucket with the given title and return the URL
• uploadS3Uuid : [Byte] -> Text
  • Upload a data to an S3 bucket with a unique name and return the URL

Build the service using nstack build. Note, you will need a drop a file in the service directory called credentials.json that contains a single json object as follows (modify as needed),

{
  "S3_ACCESS_KEY" : "...",
  "S3_SECRET_KEY" : "...",
  "BUCKET" : "uploads.demo.nstack.com"
}
