What is Nano ID?

Nano ID is a small, secure, and fast unique ID generator for JavaScript, designed as a modern alternative to UUIDs. It uses a larger, URL-friendly character set to generate shorter IDs (default 21 characters) while maintaining a similar level of security and a low collision probability compared to UUIDs. The library is portable, with implementations available in over 20 programming languages.

Key features:

  • Small and fast: It is more compact than UUIDs and generates IDs faster. The default 21-character ID is shorter, which makes it more efficient for storage and transmission.
  • Secure: It uses a cryptographically strong random number generator, making it suitable for security-sensitive applications.
  • URL-friendly: The default character set is URL-safe, which is beneficial for web applications where IDs are used in URLs.
  • Customizable: You can adjust the length and the character set of the generated IDs to meet specific needs.
  • Portable: Nano ID has been ported to many programming languages, making it a versatile choice for various projects beyond JavaScript.
