What is Sqids?

Sqids (pronounced "squids") is an open-source library that lets you generate YouTube-looking IDs from numbers. These IDs are short, can be generated from a custom alphabet and are guaranteed to be collision-free. Read more .

This is what they look like:

Go

To encode & decode:

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

Randomize IDs by providing a custom alphabet:

s, _ := sqids.New(sqids.Options{
  Alphabet: "FxnXM1kBN6cuhsAvjW3Co7l2RePyY8DwaU04Tzt9fHQrqSVKdpimLGIJOgb5ZE",
})
id, _ := s.Encode([]uint64{1, 2, 3}) // "B4aajs"
numbers := s.Decode(id) // [1, 2, 3]

Enforce a minimum length for IDs:

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