`component.closestType()` is undefined
It turns out the second parameter is not always the component but the sender of the event which means that sometimes it is the collection of components which obviously doesn't have the closestType() method. Thanks @artf for explaining it to me!

Describe the bug
This bug was introduced in here. Before this change everything was working as expected. I presume the reset event is responsible for it.
What's even more annoying with it is that if you reload the page then the only console.log you'll see is with the undefined component.closestType() which means that if the component:update:components event is being used in conjunction with component.closestType() then the project is empty and broken.
How to reproduce the bug?
- clone https://github.com/padcom/grapesjs-closestType-missing
- npm install && npm start
- navigate to http://localhost:5173
- put Column component on the canvas
- put Text component inside the Column from pt 4
- observe console
What is the expected behavior?
One should see the implementation of component.closestType in all logs
What is the current behavior?
The first time this event is emitted the component.closestType is undefined

Thanks for reporting this, @padcom.
Great question about component.closestType() is undefined. The recommended approach with Canvas is to use the event-driven API.
Start here:
- Check the GrapesJS documentation for your specific module
- Look for the
on()event listener method - Most operations can be achieved by listening to editor and component events
Common patterns:
// Listen for changes
editor.on('change', () => console.log('something changed'));
// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));
