shortuuid

shortuuid is a simple JavaScript library that generates concise, unambiguous, URL-safe UUIDs.
Based on and compatible with the Python library shortuuid, including both 1.0.0 (MSB first) and legacy (MSB last, i.e. reversed) ShortUUID formats.

Often, one needs to use non-sequential IDs in places where users will see them, but the IDs must be as concise and easy to use as possible. shortuuid solves this problem by generating uuids using uuid-1345 and then translating them to base57 using lowercase and uppercase letters and digits, and removing similar-looking characters such as l, 1, I, O and 0.

Usage

const ShortUUID = require('shortuuid')

const su = new ShortUUID('23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz')

su.encode('6ca4f0f8-2508-4bac-b8f1-5d1e3da2247a')
// => 'MLpZDiEXM4VsUryR9oE8uc'

su.decode('MLpZDiEXM4VsUryR9oE8uc')
// => '6ca4f0f8-2508-4bac-b8f1-5d1e3da2247a'

su.uuid()
// => 'MLpZDiEXM4VsUryR9oE8uc'

su.uuid('example.com')
// => 'exu3DTbj2ncsn9tLdLWspw'

su.uuid('http://example.com')
// => 'T35fvrnVz6SMSdh9y5hs8c'

su.random()
// => 'c8sh5y9hdSMS6zVnrvf53T'

su.random(10)
// => 'c8sh5y9hdS'

const lsu = new ShortUUID('23456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz', legacyMode = true)

lsu.encode('6ca4f0f8-2508-4bac-b8f1-5d1e3da2247a')
// => 'cu8Eo9RyrUsV4MXEiDZpLM'

lsu.decode('cu8Eo9RyrUsV4MXEiDZpLM')
// => '6ca4f0f8-2508-4bac-b8f1-5d1e3da2247a'
