To generate an unique ID most of us use npm libraries and node utils like uuid, crypto.randomUUID. One of the major cons is these IDs are larger in size and the shorter UUID generation will increase the probability of duplicate IDs.
Here comes the saviour, nanoid - A tiny, secure, URL-friendly, unique string ID generator for JavaScript.
Since the bigger alphabet is being used in the UUID generation, nanoid can generate random unique ids within 21 chars.
And its 2x faster and safer than other UUID generators.
Wait... This will blow your mind!
Nanoid is completely configurable from size to char's, to be used while generating the UUIDs. Then how does it avoid the probability of duplication? It comes with a collision calculator which helps to predict the probability of collision based on configuration.
It has support for various other programming languages. Checkout this awesome repo:
Nano ID
English | Русский | 简体中文 | Bahasa Indonesia
A tiny, secure, URL-friendly, unique string ID generator for JavaScript.
“An amazing level of senseless perfectionism which is simply impossible not to respect.”
- Small. 116 bytes (minified and brotlied). No dependencies Size Limit controls the size.
- Safe. It uses hardware random generator. Can be used in clusters.
-
Short IDs. It uses a larger alphabet than UUID (
A-Za-z0-9_-
). So ID size was reduced from 36 to 21 symbols. - Portable. Nano ID was ported to over 20 programming languages.
import { nanoid } from 'nanoid'
model.id = nanoid() //=> "V1StGXR8_Z5jdHi6B-myT"
