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:

let sqids = Sqids()
let id = try sqids.encode([1, 2, 3]) // "86Rf07"
let numbers = try sqids.decode(id) // [1, 2, 3]

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

let sqids = Sqids(minLength: 10)
let id = try sqids.encode([1, 2, 3]) // "86Rf07xd4z"
let numbers = try sqids.decode(id) // [1, 2, 3]

Create unique IDs by shuffling the alphabet:

let sqids = Sqids(alphabet: "k3G7QAe51FCsPW92uEOyq4Bg6Sp8YzVTmnU0liwDdHXLajZrfxNhobJIRcMvKt")
let id = try sqids.encode([1, 2, 3]) // "XRKUdQ"
let numbers = try sqids.decode(id) // [1, 2, 3]
