What is Sqids?

Sqids (pronounced "squids") is an open-source library that lets you generate short unique identifiers from numbers. These IDs are URL-safe, can encode several numbers, and do not contain common profanity words. Read more .

This is what they look like:

Quick encode & decode example:

(def sqids
  (sqids/sqids))
(def id
  (sqids/encode sqids [1 2 3])) ; "86Rf07"
(def numbers
  (sqids/decode sqids id)) ; [1 2 3]

If IDs are too short, you can pad them to a certain length:

(def sqids
  (sqids/sqids {:min-length 10}))
(def id
  (sqids/encode sqids [1 2 3])) ; "86Rf07xd4z"
(def numbers
  (sqids/decode sqids id)) ; [1 2 3]

Create unique IDs by shuffling the alphabet:

(def sqids
  (sqids/sqids {:alphabet "k3G7QAe51FCsPW92uEOyq4Bg6Sp8YzVTmnU0liwDdHXLajZrfxNhobJIRcMvKt"}))
(def id
  (sqids/encode sqids [1 2 3])) ; "XRKUdQ"
(def numbers
  (sqids/decode sqids id)) ; [1 2 3]
