Is it feasible to create a short link for a Firebase UID?

Seeking guidance on a potential challenge that I'm facing, and I'm hoping for some expert advice.

With AngularFire, I am looking to customize the uids generated on push. My goal is to create a functionality for sharing dynamic paths in Firebase, so instead of:

https://url.firebaseio.com/lists/-KGhj0n_wN1xyhtu7HOR

I would prefer something like:

https://url.firebaseio.com/AbcDe

This custom "generator" would create a new uid while still pointing to "-KGhj0n_wN1xyhtu7HOR".

Is this customization possible and beneficial, or are there alternative approaches worth considering?

Answer №1

Absolutely feasible. Begin by establishing a new primary list, where you associate your concise links with the list identifiers.

shortlinks: {
  "XyZaBc": "-LMnopq_rO2zwvix8IPS"
}

Whenever someone accesses a brief link, you can effortlessly retrieve the corresponding list ID through:

ref.child('shortlinks').child(shortlinkFromAddress).once('value', function(snapshot) {
  if (snapshot.exists()) {
    // ACTION: load the list using the key snapshot.val()
  }
  else {
    console.error('This is an invalid shortlink');
  }
})

You will need to resolve the remaining challenges

  • how will you generate the shortened links? Firebase push identifiers (obtained from $firebaseArray.$add() or Firebase.push()) are lengthy to ensure uniqueness. Shorter links are more memorable, but you must ensure their uniqueness. Refer to the solution in How do you prevent duplicate user properties in Firebase?, and other related queries.
  • if you devise a method to create shorter and unique links, why not use them as list keys? Instead of saving the list under -LMnopq_rO2zwvix8IPS, save it under XyZaBc. This eliminates the need for a lookup operation.
