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
}
```
