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.
