[FEAT]: Warning popup when duplicate destination URL exists

[steven-tey]

Via a user request:

We have a very distributed, remote, volunteer team, and we're trying to more consistently enforce using shortened links so we have better click tracking, but sometimes team members will go in to create a link for something that already has a link, not knowing that it exists. We'd love to have the option to enable a warning popup if the Destination URL specified when creating a new link already exists in another Short Link.

ENG-337 [FEAT]: Warning popup when duplicate destination URL exists

I'd be happy to work on this.

One question to understand the requirements better:

• Do we need to normalise the destination URLs before running the checks?
  • For example: https://www.google.com & https://google.com - should these both be considered the same destination URL?
