About

optimal-id is a small optimized library that generates an optimized string based id value suitable for nosql database unique keys.

It is based upon the research and works of Peter Zaitsev and Karthik Appigatla.

Assuming a standard v1 UUID of "4a6b9f70-b678-11eb-a7b6-032e6afcbc8e"

This code provides the string "11ebb6784a6b9f70a7b6032e6afcbc8e"

• rearranges bytes of timestamp for ordered ids
• removes separator dash characters because we don't need to waste 4 bytes per id
• zero third-party dependency libraries for a smaller payload

Installation

Install the package into your project.

Using NPM

npm install --save optimal-id

Usage

Using JavaScript ES5

var optId = require('optimal-id').optId;

// generate one id
var id = optId.generate()[0];

// generate multiple ids
var NUM_IDS_TO_GENERATE = 100;
var ids = optId.generate(NUM_IDS_TO_GENERATE);

or

Using JavaScript ECMAScript 2015 or later

const { optId } = require('optimal-id');

// generate one id
const [id] = optId.generate();

// generate multiple ids
const NUM_IDS_TO_GENERATE = 100;
const ids = optId.generate(NUM_IDS_TO_GENERATE);

or

Using Typescript

import { optId, OptimalId } from 'optimal-id';

// generate one id
const [id]: OptimalId[] = optId.generate();

// generate multiple ids
const NUM_IDS_TO_GENERATE = 100;
const ids: OptimalId[] = optId.generate(NUM_IDS_TO_GENERATE);
