preLayout

The preLayout lifecycle hook runs just before the pattern layout is calculated.

This is a good place to do any business that might change the layout but relies on all the parts having been drafted

Signature

null hook(Pattern pattern)

Example

pattern.on('preLayout', pattern => {
  // Mutate the pattern object here
}

Notes

The postLayout hook is rarely used, but it's there if you need it.
