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:

local sqids = Sqids.new()
local encoded = sqids:encode({ 1, 2, 3 }) -- 86Rf07
local decoded = sqids:decode(encoded) -- 1, 2, 3

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

local sqids = Sqids.new({
  minLength = 10,
})
local encoded = sqids:encode({ 1, 2, 3 }) -- 86Rf07xd4z
local decoded = sqids:decode(encoded) -- 1, 2, 3

Create unique IDs by shuffling the alphabet:

local sqids = Sqids.new({
  alphabet = "k3G7QAe51FCsPW92uEOyq4Bg6Sp8YzVTmnU0liwDdHXLajZrfxNhobJIRcMvKt",
})
local encoded = sqids:encode({ 1, 2, 3 }) -- XRKUdQ
local decoded = sqids:decode(encoded) -- 1, 2, 3
