What is Nanoid?
Nanoid is a tiny, secure, URL-friendly, unique string ID generator for JavaScript. It is a modern alternative to UUID that is faster and produces shorter identifiers while maintaining a similar level of security and collision resistance.
Key Features
- Safe: Uses a hardware random generator (crypto API) for security.
- Compact: Uses a larger alphabet (A-Za-z0-9_-) than UUID (hex), packing more entropy into fewer characters (21 chars vs 36).
- Fast: Designed for high performance, often faster than UUID generation.
When to use Nanoid?
Use Nanoid when you generally need a unique ID but want something shorter than a UUID, especially for URLs (e.g., `youtube.com/watch?v=dQw4w9WgXcQ`). It's perfect for customer-facing IDs where length matters.
