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` fires once for each set in the pattern.
The pattern tracks the active set on the `activeSet` property.
So if you are using this hook and would like to get access to teh active set, you can do so like this:
```js
pattern.on('preSetDraft', ({ settings, activeSet }) => {
const set = settings[Number(activeSet)]
// Now set holds the active set of settings
}
```
