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:
let sqid = initSqids()
let id = sqid.encode([1, 2, 3]) # "86Rf07"
let numbers = sqid.decode(id) # @[1'u64, 2, 3]
If IDs are too short, you can pad them to a certain length:
let sqid = initSqids(minLength = 10)
let id = sqid.encode([1, 2, 3]) # "86Rf07xd4z"
let numbers = sqid.decode(id) # @[1'u64, 2, 3]
Create unique IDs by shuffling the alphabet:
let sqid = initSqids(
alphabet = "k3G7QAe51FCsPW92uEOyq4Bg6Sp8YzVTmnU0liwDdHXLajZrfxNhobJIRcMvKt",
)
let id = sqid.encode([1, 2, 3]) # "XRKUdQ"
let numbers = sqid.decode(id) # @[1'u64, 2, 3]

The main use of Sqids is purely visual. If you'd like to use IDs instead of numbers in your project, Sqids could be a good choice.
