Insitefulickr

A quick and fun challenge playing with Flickr's API.

PROS 👍:

• Clear seperation of concerns--allowing for scalability.
• lib/* are small, light, portable, easily testable, and reusable in other projects.
  • lib/flickr methods are all pure and take a single argument with a consistent response of an array of objects (collection).

CONS 👎:

• Safety Not Garunteed ‼
  • Any updates/breaking-changes to flickr-sdk could 🔩 me.
  • lib/flickr.* is fragile and operates on the assumption of consistent data structures.
  • lib/flickr.formatting order matters for both the photos collection and sizes collection.
