method Crypto.randomUUID
#Crypto.randomUUID(): `${string}-${string}-${string}-${string}-${string}`Generates a random RFC 4122 version 4 UUID using a cryptographically secure random number generator.
Examples #
#
const uuid = crypto.randomUUID();
console.log(uuid);
// Example output: '36b8f84d-df4e-4d49-b662-bcde71a8764f'
The randomUUID method generates a version 4 UUID, which is purely
random. If you require other versions of UUIDs, such as time-based (v1) or
name-based (v3 and v5), consider using the @std/uuid package available
at https://jsr.io/@std/uuid.
#
import { v1 } from 'jsr:@std/uuid';
// Generate a time-based UUID (v1)
const uuidV1 = v1.generate();
console.log(uuidV1);
// output: 'a0c74f7e-82f1-11eb-8dcd-0242ac130003'
Return Type #
`${string}-${string}-${string}-${string}-${string}` A randomly generated, 36-character long v4 UUID.
