At Beyond we absolutely love working with the latest technologies and take great care in producing solid apps and user friendly, aesthetically pleasing interfaces for our clients.

Before we get you in for a chat we would love to see you in action so have put together a small task for you to showcase your coding skills. We would like you to implement a simple image processing web API.

The application should provide endpoints for creating image objects in a datastore, managing the objects in the datastore and providing new (resized) renditions of existing image objects already present in the datastore.

• NodeJS should be used as the web server.
• Data should be stored in a NoSQL based datastore.
• Security aspects should be taken into consideration.
• The application and the datastore should be deployed as Docker containers.
• Your submission should include run instructions to bootstrap the containerized application locally.
• Version control via a git repository.

Your implementation should adhere the to OpenAPI 2.0 specification defined in the swagger.yaml file in this repository. This definition can be summarized as follows:

• As an authenticated user, I should be able to use a create and delete image objects in the datastore.
• As an anonymous user, I should be able view image objects via a public url.
• As an anonymous user, I should be able to get a resized rendition of existing image objects via a public url.

If you have the time and inclination, here are some things you could implement for extra credit.

• Caching of resized image renditions.
• Add additional image processing endpoints (eg rotate, grayscale, etc)
• Add pagination to the list image objects endpoint.
• Write a terraform module to provision an AWS environment to host the application, and a script to deploy the application to the environment.
