FAQ
What is UUID v7? A 128-bit ID whose first 48 bits are Unix time in milliseconds, so IDs roughly sort by creation time. Version nibble is 7; RFC variant bits are set.
Does this send IDs to a server? No. Generation uses crypto.getRandomValues in this page.
v7 or v4? Use v7 when you want time-sortable primary keys. Use v4 when you only need unguessable random IDs.
