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:

s, _ := sqids.New()
id, _ := s.Encode([]uint64{1, 2, 3}) // "86Rf07"
numbers := s.Decode(id) // [1, 2, 3]

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

s, _ := sqids.New(sqids.Options{
  MinLength: 10,
})
id, _ := s.Encode([]uint64{1, 2, 3}) // "86Rf07xd4z"
numbers := s.Decode(id) // [1, 2, 3]

Create unique IDs by shuffling the alphabet:

s, _ := sqids.New(sqids.Options{
  Alphabet: "k3G7QAe51FCsPW92uEOyq4Bg6Sp8YzVTmnU0liwDdHXLajZrfxNhobJIRcMvKt",
})
id, _ := s.Encode([]uint64{1, 2, 3}) // "XRKUdQ"
numbers := s.Decode(id) // [1, 2, 3]
