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:
JavaScript code is located at https://github.com/sqids/sqids-javascript
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]

The main use of Sqids is purely visual. If you'd like to use IDs instead of numbers in your webapp, Sqids could be a good choice:
