Function customRandom

Generate unique ID with custom random generator and alphabet.

Alphabet must contain 256 symbols or less. Otherwise, the generator will not be secure.

import { customRandom } from 'nanoid/format'

const nanoid = customRandom('abcdef', 5, size => {
  const random = []
  for (let i = 0; i < size; i++) {
    random.push(randomByte())
  }
  return random
})

nanoid() //=> "fbaef"
