    Universally Unique Lexicographically Sortable Identifier (ULID) in Python 3 (by ahawker)

    I really like ULID for this problem (e.g: https://github.com/ahawker/ulid)

    - same number of bytes as UUID

    - start with a date, so has great locality. Plus you get extra information in the uid that you can extract.

    - can be created from an existing date or uuid, and exported to a uuid, so there is a migration path

    Swyx's second brain! (by sw-yx)

    I've been collecting all my notes on UUIDs here https://github.com/sw-yx/brain/blob/master/R%20-%20Dev%20Not... in case it is helpful to anyone

  • js-id

    ID generation for JavaScript & TypeScript Applications

    We evaluated ULID but we wanted something that is future proof for our decentralised secret sharing system. So we implemented UUIDv7 in TypeScript called `IdSortable` https://github.com/MatrixAI/js-id

    It allows strict monotonic IDs when you provide it the previously generated ID. The resulting data structure is a Uint8Array making it easy to put into binary structures. Can also be used as a key inside any POJO record.
