What is Classic Editor in CKEditor5?

Classic editor is what most users traditionally learned to associate with a rich text editor — a toolbar with an editing area placed in a specific position on the page, usually as a part of a form that you use to submit some content to the server.
CkEditor5 Classic Editor is not yet supported in IE11 browser.
The below code is tested in Chrome, Mozilla, and Edge.
To integrate CKEditor5 (Classic Editor) in your SharePoint Framework please refer to my previous blogs.
rteEvent - CKEditor5 event.

  3.         try {    
  4.                 const viewFragment =;    
  5.                 const modelFragment =;    
  6.                 rteEvent.model.insertContent(modelFragment, rteEvent.model.document.selection);                    
  7.             }
