chrisgreg / dfuid

A dumb fast unique ID generator for Node

dfuid

What is this?

A very small, light module to produce distributed unique ID's for whatever purpose required. This solution does not use any sort of cryptography to generate results - it produces a string out of some random numbers and provides you access to the hostname as well optionally.

What does dfuid stand for?

Dumb Fast Unique ID

Why should I use this over UUID or shortid?

If you need to generate an ID ridiculous quickly, the alternatives are too slow, and you don't require anything specific in generation.

Installation

$ npm install --save dfuid

Example Use

import dfuid from 'dfuid';
const myId = dfuid();
// myId = chriss-mbp-0.0724114346331552774

Testing

$ npm test
