sequential-uuid

A Node.js utility for generating timestamp based sequential uuid.

Usage

After installing with npm i sequential-uuid :

const SequenceUUID = require('sequential-uuid')
const uuid = new SequenceUUID()
uuid.generate() // '5d6865a2-8184-a0a4-98b5-a8c8d4931f01'

Options

| Name | Description | Type | Default | | ------------ | :---------------------------------------------------: | :---: | ------: | | dashes | Toggle dashes separation | bool | true | | valid | Generate only valid UUID v4 | bool | false | | unsafeBuffer | Use unsafe buffer allocation (for better performance) | bool | false |

Options can be passed as object:

const uuid = new SequenceUUID({
  valid: true,
  dashes: false,
  unsafeBuffer: true
})

Generated UUID

All UUID's generated by this library are built with 4 bytes of timestamp and 12 secure random bytes generated with crypto library.
