Use `crypto.randomUUID()` to generate a UUID v4. It works in Bun, Node.js, and browsers, with no dependencies.
|
||
|
|
|
||
|
|
```ts
|
||
|
|
crypto.randomUUID();
|
||
|
|
// => "123e4567-e89b-42d3-a456-426614174000"
|
||
|
|
```
|

Bun also provides `Bun.randomUUIDv7()`, which generates a [UUID v7](https://www.rfc-editor.org/rfc/rfc9562.html#name-uuid-version-7).
|
||
|
|
|
||
|
|
```ts
|
||
|
|
Bun.randomUUIDv7();
|
||
|
|
// => "0196a000-bb12-7000-905e-8039f5d5b206"
|
||
|
|
```
