sequential-guid

Node package for generating sequential unique identifiers based on unique guid seed. Generation guids version 1 and 4 cannot be done without node-uuid library, thank you Broofa.

Getting Started

Install it in your browser:

<!-- Don't forget to include 'node-uuid' dependency (https://github.com/broofa/node-uuid) -->
<script src="sequid.js"></script>

Or in node.js:

npm install sequential-guid

var Uid = require('sequential-guid')

...and create object

  var uid = new Uid

Creating new instance of guid class cause generation of the seed

  console.log( uid.seed )   // output guid like this: 6e44dc51-804d-47ab-a933-f94641cf86cf

You can deffer generating seed value by seting deferInit property. Now new object has undefined seed until you call next() method on it, we can also specify value for seed

  Uid.prototype.deferInit = true
  var iid = new Uid
  iid.seed = '00000000-0000-4000-a000-000000000000'

lets generate unique identifiers

  console.log( uid.next() )	// '00000000-0000-4000-a000-000000000001'
  console.log( uid.next() )	// '00000000-0000-4000-a000-000000000002'
  console.log( uid.next() )	// '00000000-0000-4000-a000-000000000003'
  console.log( uid.next() )	// '00000000-0000-4000-a000-000000000004'
  console.log( uid.next() )	// '00000000-0000-4000-a000-000000000005'

That's all, thanks for reading :)
