Replacements for shortid

nanoid

nanoid is a tiny, secure, URL‑friendly, unique string ID generator. It’s also faster than shortid.

Good to know before migration

• shortid.isValid(id): there’s no direct equivalent. Validate with a regex that matches your chosen alphabet and length, e.g. /^[A-Za-z0-9_-]{21}$/.

• shortid.seed()/shortid.worker(): not needed and not provided by nanoid (it uses a secure random source). Avoid seeded/deterministic IDs for security.

Basic migration

import shortid from 'shortid'
import { nanoid } from 'nanoid'

const id = shortid.generate() 
const id = nanoid() // => "V1StGXR8_Z5jdHi6B-myT"

Control length

// shortid produced ~7-14 chars; with nanoid you pick the size explicitly:
nanoid(10) // e.g., "NG3oYbq9qE"

Custom alphabet (replacement for shortid.characters)

shortid.characters('0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ$@') 
import { customAlphabet } from 'nanoid'

const alphabet = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ$@'
const makeId = customAlphabet(alphabet, 12) 
const id = makeId()
