Uploadsigner

Crystal shard to provide API for generating pre-signed URLs for file uploads to cloud storage. This shard was created to provide direct to cloud uploads using browser functionality to PlaceOS, but is designed to be generic and can be used with any library and/or application.

Currently only supports Amazon S3

Benefits of moving file uploads functionality near to end user are:

• Off-loads processing to client machines
• Better guarantees against upload corruption
• file hashing on the client side
• Upload results are guaranteed
• user is always aware of any failures in the process
• Detailed progress and control over the upload
