Shortie

An API for creating, using, and deleting short urls.

Implementation Assumptions

1. Use the URL shortener just for the host and path, that way the short url can be used with parameters without needing a new entry. This design decision could be changed fairly easily or a parameter could allow both options.
2. The statistics are collected on a best-effort bases - as in, they might not be fully accurate under high load or errors. Implementations that require full accuracy in a distributed system should be built with an event based system that can be idempotent.
3. URL shorteners are for GET requests? I'm not super sure about this, but I suppose I could support other HTTP verbs 🤷.
