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:

To encode & decode:

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

Randomize IDs by providing a custom alphabet:

const sqids = new Sqids({
  alphabet: 'FxnXM1kBN6cuhsAvjW3Co7l2RePyY8DwaU04Tzt9fHQrqSVKdpimLGIJOgb5ZE',
})
const id = sqids.encode([1, 2, 3]) // "B4aajs"
const numbers = sqids.decode(id) // [1, 2, 3]

Enforce a minimum length for IDs:

const sqids = new Sqids({
  minLength: 10,
})
const id = sqids.encode([1, 2, 3]) // "86Rf07xd4z"
const numbers = sqids.decode(id) // [1, 2, 3]
