  1. TypeID is similar, though it uses the UUIDv7 directly: https://github.com/jetify-com/typeid Maybe the formalization would be interesting to you. It doesn't have a checksum, though, that seems like an improvement that's worth a few bytes.

  2. I prefer TypeID: https://github.com/jetify-com/typeid

  3. I used https://github.com/jetify-com/typeid for generating api keys for a project. They are nice because you can use prefixes for different type of keys and know immediately what they represent. No dashes also makes them easier to copy…

  4. There's a similar proposal called TypeID: https://github.com/jetify-com/typeid E.g.: user_2x4y6z8a0b1c2d3e4f5g6h7j8k

  5. I went to add your UUID variant to my notes and found https://github.com/jetify-com/typeid The main differences: - typeid allows up to a 63 byte prefix - typeid follows it with a full 128-bit UUID I prefer your implementation generally I…

  6. …your database much happier than using long string PK's. 0: https://www.crockford.com/base32.html 1: https://github.com/jetify-com/typeid

  7. I feel like https://github.com/jetify-com/typeid is the solution to this

  8. There’s a project called typeid which implements an ID scheme similar to Stripe. https://github.com/jetify-com/typeid
    comment by madjam002 · 2024-05-03 · in Ask HN: What does stripe use for their unique IDs?
  9. I’ve seen this sort of design referred to as “typed IDs”: https://github.com/jetify-com/typeid Doesn’t use the crockford encoding, but does is another one that minimises confusables. Definitely looks pretty solid, so keen to give them a…

  10. …But there is always TypeID in the meantime which uses UUIDv7 under the hood: https://github.com/jetify-com/typeid Either way, I am in favor of prefixing and using alternative encodings, but it will need some time to figure out the best
    comment by Daegalus · 2024-04-11 · in The UX of UUIDs
  11. …you could incorporate: - K-sortable: ensures good locality when used as an id in a database (e.x. https://github.com/jetify-com/typeid https://github.com/segmentio/ksuid ) - checksum: primarily useful when an id might be conveyed verbally…

  12. The author seems to be unaware of TypeID. You can use TypeID and ignore this article. https://github.com/jetify-com/typeid
    comment by shinzui · 2024-04-11 · in The UX of UUIDs
  13. If you want a type-prefixed UUIDv7 type, I can wholeheartedly recommend TypeID-JS: https://github.com/jetpack-io/typeid-js Also available for a whole bunch of other languages: https://github.com/jetpack-io/typeid UUIDv7 is…

  15. They use a type safe extension of UUIDv7 Here is a go implementation and explanation: https://github.com/jetpack-io/typeid

  16. …and retain locality, by using UUIDv7. At jetpack.io we've been doing exactly that via TypeIDs: https://github.com/jetpack-io/typeid and there's a PostgresSQL implementation available. TypeIDs are UUIDv7 with additional type information, so…
