Feat/url tagging

[ptbarnum4]

WIP: Initial idea for url tagging

• Accepts optional tag in URL
  • /:code/:tag?

examples

Resolve the second param as tag code

TODO:

• Create Tags collection
• Add a "tag" when we want to correlate user to link (where and how I'm not sure, maybe through this API we can allow some reference.. I think we should discuss this)
  • Tags should contain a reference to the user, email, and short link

Path: /code/tagcode
Resolved  → `{ code: "code", tag: "tagcode"}`

Path: /abc123/zyx987
Resolved  → `{ code: "abc123", tag: "zyx987"}`

Resolves tag as empty string if it doesn't exist

Path: /abc123
Resolved  → `{ code: "abc123", tag: "" }`

Ignores extra params

Path: /abc123/zyx987/ignored
Resolved  → `{ code: "abc123", tag: "456" }`

Fix lint errors to specify key
