About JIS

JIS is a simple prototype of two services exposing REST(-ish) APIs and sharing information asynchronously over a queue (RabbitMQ) and Amazon S3.

Implementation notes

  • The backend/ module is shared between photo-service and exif-service. This could be improved by each service having their own backend module to reduce coupling and enable service independance and easier changes.
  • The RabbitMQ code is not production grade, but provides an sample implementation of asynchronous communication.
  • Uses the notorious MongoDB for storage.
  • Photos get fully buffered in memory during uploads/downloads from S3.
  • File extensions are disregarded.
  • Heavy on the use of optionals and "finals".
