How to create new custom manager?

During this time, I tried to add my custom manager to grapesjs on npm.

// editor/index.js
        ['Styles', 'StyleManager'],
        'DeviceManager',
        ['Devices', 'DeviceManager'],
        'PackageManager', //this
      ].forEach(prop => {
        if (Array.isArray(prop)) {
          this[prop[0]] = em.get(prop[1]);

and

//editor/model/Editor.js

const deps = [
...
  require('block_manager'),
  require('package_manager'), // this
];

However, I failed.

This is my test code:

export default () =>{
    return {
        name : "PackageManager",

        test(){
            console.log("hello form package manager");
        }
    }
}

When I build, I am taking a blank page. Please rescue me from this black hole.

Thanks.

Thanks for reporting this, @fzerman.

Great question about QUESTION : How to create new custom manager?. The recommended approach with GrapesJS 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));

If you're still stuck:

• Share a minimal CodeSandbox reproduction
• Include what you've already tried
• Mention your GrapesJS version
