About

ShortID is a compact unique identifier, typically 8-12 characters long. It's generated using a URL-safe alphabet and provides a good balance between uniqueness and brevity. ShortIDs are useful for user-facing identifiers, short URLs, or when you need compact but unique identifiers. The length can be customized to suit your needs, with shorter IDs being more readable but having lower uniqueness guarantees. This implementation uses NanoID with a custom length.

Use Cases

  • •User-facing identifiers and codes
  • •Short URL slugs and links
  • •Invite codes and referral codes
  • •Compact API identifiers
  • •Human-readable unique IDs
  • •Systems requiring short but unique identifiers

How to Generate

Library

nanoid

NPM Package

npm install nanoid

Code Example

import { nanoid } from 'nanoid';
// Generate short ID with custom length
const shortId = nanoid(8);
console.log(shortId); // e.g., 'V1StGXR8'

Note: Shorter IDs have lower uniqueness guarantees. Use longer IDs (12-21 characters) for higher collision resistance.
