title: preSetDraft
|

|

|
|
The `preSetDraft` lifecycle hook runs just before a set (of settings) is
|
||
|
|
drafted. It will fire once for each set when calling `Pattern.draft()`.
|
||
|
|
|
||
|
|
## Signature
|
||
|
|
|
||
|
|
```js
|
||
|
|
null hook(Pattern pattern)
|
||
|
|
```
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
```js
|
||
|
|
pattern.on('preSetDraft', pattern => {
|
||
|
|
// Mutate the pattern object here
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Notes
|
||
|
|
|
||
|
|
The `preSetDraft` hook is rarely used, but it's there if you need it.
