Generate a UUID

Use crypto.randomUUID() to generate a UUID v4. This API works in Bun, Node.js, and browsers. It requires no dependencies.

crypto.randomUUID();
// => "123e4567-e89b-42d3-a456-426614174000"

In Bun, you can also use Bun.randomUUIDv7() to generate a UUID v7.

Bun.randomUUIDv7();
// => "0196a000-bb12-7000-905e-8039f5d5b206"
