|
|
---
|
|
|
|
The `preDraft` lifecycle hook runs just before your pattern is drafted.
|
|
|
|
## Signature
|
|
|
|
```js
|
|
null hook(Pattern pattern)
|
|
```
|
|
|
|
## Example
|
|
|
|
```js
|
|
pattern.on('preDraft', pattern => {
|
|
// Mutate the pattern object here
|
|
}
|
|
```
|
|
|
|
## Notes
|
|
|
|
The `preDraft` hook is rarely used, but it's there if you need it.
