Unique ID Generation

Unique ID generation libraries in JavaScript provide developers with tools to create identifiers that are guaranteed to be unique across different contexts, such as databases, web applications, and distributed systems. These libraries implement various algorithms to generate IDs that can be used as primary keys, session tokens, or any other purpose where uniqueness is required. The generated IDs can vary in length, format, and complexity, depending on the library and the configuration options provided. Using a reliable unique ID generator helps prevent collisions, ensures data integrity, and enhances the overall functionality of applications that require distinct identifiers for their entities. nanoid is a tiny, secure, and URL-friendly unique string ID generator that is faster and smaller than UUIDs, making it ideal for modern web applications. short-uuid is a library for generating short, unique, and URL-friendly IDs using customizable alphabets and encoding methods, providing a balance between uniqueness and brevity. shortid is a simple and fast library for generating short, unique, and non-sequential IDs that are URL-friendly, but it is no longer actively maintained. uuid is a widely-used library for generating universally unique identifiers (UUIDs) based on established standards, offering various versions and methods for creating UUIDs that are suitable for a wide range of applications.

Nano ID

Nano ID logo by Anton Lovchikov

English | 日本語 | Русский | 简体中文 | Bahasa Indonesia | 한국어 | العربية

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. 118 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"
