UUID v4 generator for fixtures and APIs
UUIDs let services mint IDs without a central sequence. Laravel migrations, Nuxt mock stores and test seeds all need a handful of unique values quickly.
This generator uses crypto.randomUUID() in the browser to create UUID version 4 identifiers. Set a count and copy a list. Collision risk is negligible for fixtures and most application keys.
v4 IDs are random, not sortable. If you need time-ordered keys for MySQL indexes, consider ULID or UUID v7 in application code.
