Questions tagged [shrine]

Shrine is a file upload toolkit for Ruby, it's designed to be simple, extensible, secure and fast, and provides an abstraction for different storages.

Shrine is a file upload toolkit for Ruby with the following characteristics:

  • It's composed entirely out of plugins, making it very extensible and flexible

  • It makes direct AJAX uploads to the application or S3 dead easy

  • It's designed from day one with backgrounding in mind (Sidekiq, Resque etc.), but it still retains seamless user experience

  • It provides a simple instance-level interface for file processing and validations

  • It comes with filesystem and S3 storage, but provides nice abstraction for other storages as well

It was created and is currently maintained primarily by Janko Marohnić.
