Update the page

How do you update the page? Worth nothing, page:* events are only triggered for page models, not the content of the page, eg.

editor.Pages.getSelected().setName('My page');

any update, dragging a block, changing text color. changing text content. In the JS Fiddle, I drag a Text block, change content, and change color. I do not see an event triggering when i make these updates, so I am questioning my expectations

I am trying to understand the best way to build a custom Storage Manager. I have been using grapess for a long time, and have lots of "middleware" between grapes and my server/database. I am in the process of upgrading Grapes, so I am trying to understand the best EVENT to tap into to keep track of changes made.

Ultimately, I am learning more about the Store Manager, and I have confidence that will get me to where I need to go.

Nonetheless, I would like to understand Page Manager.... I will have to think about what you say about page model.

Ok so page:update event is not what you need as it doesn't trigger on content change (so I'm closing the issue as the event is working as expected). Can you explain what kind of custom Storage manager you're trying to build? The Storage manager itself is already triggering on content change so I don't understand why you're trying to rebuild that functionality.

Thanks for reporting this, @stljeff1.

Great question about Page update event doesn't fire. The recommended approach with StyleManager is to use the event-driven API.

Start here:

  1. Check the GrapesJS documentation for your specific module
  2. Look for the on() event listener method
  3. 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));
