          grapesjsCss="/grapesjs/dist/css/grapes.min.css"
/>

using local copy from "npm install grapesjs" because the remote source map does not work for me version copied from the source file: /*! grapesjs - 0.21.7 */

I can only suggest to check properly the source map path <img width="346" alt="Screenshot 2024-02-12 at 08 45 32" src="https://github.com/GrapesJS/grapesjs/assets/11614725/ee135460-a758-4aef-96fa-1d1b463c934d">

For example, it won't work if you try to load grapesjs via CDN like this https://unpkg.com/grapesjs (here a redirect is happening) as in this case the URL would be https://unpkg.com/grapes.min.js.map. It would work though if try with the full resource URL https://unpkg.com/[email protected]/dist/grapes.min.js, here the final URL would be https://unpkg.com/[email protected]/dist/grapes.min.js.map and it's correct.

Thanks for reporting this, @addlistener.

Great question about sourcemap not loading for CompoentTextView. The recommended approach with ProseMirror 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
