tiptap VS ckeditor5-react

The Editor: The core of our app is the editor. We need an easy to use and robust rich text editor, that supports all of the features we want such as: headings, lists, placeholders, markdown, color, images, bold italic etc… For this we will use @10play/tentap-editor which is a rich text editor for react native based on Tiptap.

A WYSIWYG rich-text editor using tiptap2 and Element Plus for Vue3

You can build a Notion-like editor on top of https://tiptap.dev :-) Here is a demo of what such an editor might look like: https://demos.tiptap.dev/

Since Tiptap is headless, you have the freedom to design and develop the UI exactly the way you want.

The first link shows a discussion that started in July 2020, when Tiptap was only available in version 1. The new major version 2, which is a complete rewrite, was in development. The biggest drawback the GitLab engineers had was the lack of a test suite in Tiptap 1. That's understandable, because as a key component of your application, testing is necessary to ensure that you catch breakable changes. Tiptap 2 does just that. [1]

No good tool is built without using good tools, and Vrite Editor is no different. Before getting into WYSIWYG editors, I extensively researched available RTE frameworks, that could provide the tooling and functionality I was looking for. Ultimately, I picked TipTap and underlying ProseMirror — IMO, the best tools currently available for all kinds of WYSIWYG editors.

Nodejs has hocuspocus (built on prosemirror) (https://www.npmjs.com/package/@hocuspocus/server) using tiptap (https://tiptap.dev/), are there any similar alternative backends in Go?

If you're in need of a solid editor library for your next project, be sure to check out Tiptap. It's an open-source project, and we always appreciate feedback and contributions!

The buttons had to be absolutely positioned, which required both a custom TipTap extension and tapping deeper into the underlying ProseMirror (both libraries powering the Vrite editor).

ckeditor v4 had allowedContent and extraAllowedContent configurations to allow classes on elements. Searching for "ckeditor 5 allowedContent" led me to https://github.com/ckeditor/ckeditor5-react/issues/209 which seems to indicate to me that they've gone a whole different route for configuration and I'll leave it to you to deep dive into that.
