  format: ID2.Converter.format('XXXX-00000', {
    X: 'ACFHJKPRSTUVWXYZ',
    0: '234567'

})

Convert number to string

id2.stringify(0)
// => 'AAAA-22222'
id2.stringify(1)
// => 'AAAA-22223'
id2.stringify(1234567)
// => 'AATY-65553'
id2.stringify(id2.numberOfAvailableIDs - BigInt(1))
// => 'ZZZZ-77777'

Convert string to number

id2.parse('AAAA-22222')
// => 0n
id2.parse('AAAA-22223')
// => 1n
id2.parse('AATY-65553')
// => 1234567n

// => 'bae8b334-a84b-4d25-ba49-3b943cfc849d'
id2.stringify(id2.numberOfAvailableIDs - BigInt(1))
// => 'ffffffff-ffff-4fff-bfff-ffffffffffff'

Convert string to number

id2.parse('00000000-0000-4000-8000-000000000000')

Options
format

for ID pattern [A-Z]{3}-[0-9]{4}

new ID2.Converter({
  format: [
    {
      characters: 'ABCDEFGHIJKLMNOPQRSTUVWXYZ',
      repeats: 3
    },
    {
      characters: '-',
    },
    {
      characters: '0123456789',

  format: ID2.Converter.format('XXX-0000', {
    X: 'ABCDEFGHIJKLMNOPQRSTUVWXYZ',
    0: '0123456789'
  })
}
