Analyzing New Unique Identifier Formats (UUIDv6, UUIDv7, and UUIDv8) (2022)

• nanoid

  85 24,315 8.3 JavaScript

  A tiny (124 bytes), secure, URL-friendly, unique string ID generator for JavaScript

  In another comment I mentioned I use nanoid in my projects now. It has a default space of 64^21 and has an a page where you can play with key lengths and alphabet sizes and see the probability of collisions :

  https://zelark.github.io/nano-id-cc/

  At the default 64 character alphabet with a 21 character key length it would take ~41 million years in order to have a 1% probability of at least one collision if you generated 1000 ids per second.

  2 259 5.0 Java

  A Java library for generating Time-Sorted Unique Identifiers (TSID).

  See also: https://github.com/vladmihalcea/hypersistence-tsid (shorter than UUID)

• spec

  63 9,556 0.0

  The canonical spec for ulid

  

  ULIDs, https://github.com/ulid/spec, are also already in widespread use and are essentially the same idea as v7 UUIDs.

• javascript

  3 2,961 0.0 JavaScript

  Universally Unique Lexicographically Sortable Identifier (by ulid)

  

  The spec as written on that page is confusing on that point, but the incrementing-counter-within-the-same-millisecond-behavior only happens if you explicitly specify a "monotonicFactory", https://github.com/ulid/javascript#monotonic-ulids. The default behavior (just using the ulid() function) doesn't do that, it generates a completely random value regardless of the millisecond value.
