nuid

NODE NUID

A highly performant unique identifier generator.

Installation

Use the npm command:

$ npm install nuid

Basic Usage

const NUID = require('nuid');
let nuid = NUID.next();


// Generate a new crypto/rand seeded prefix.
// Generally not needed, happens automatically.
NUID.reset();

Performance

NUID needs to be very fast to generate and be truly unique, all while being entropy pool friendly. NUID uses 12 bytes of crypto generated data (entropy draining), and 10 bytes of pseudo-random sequential data that increments with a pseudo-random increment.

Total length of a NUID string is 22 bytes of base 36 ascii text, so 36^22 or 17324272922341479351919144385642496 possibilities.
