prefixed-id

Generates random ids with a prefix (like Stripe)

Based on id-generator by Auth0.

Installing

npm install prefixed-id

Using

Simple case:

var PrefixedId = require('prefixed-id');

var generator = new PrefixedId();
var id = generator.new('cus');

console.log(id); // cus_lO1DEQWBbQAACfHO

Predefined set of allowed prefixes (to avoid mistakes):

var PrefixedId = require('prefixed-id');

var generator = new PrefixedId(['cus', 'con']);
var id = generator.new('cus');

console.log(id); // cus_lO1DEQWBbQAACfHO

generator.new('cli'); // throws
