Upgrade CKEditor

[taylortom]

CKEditor 4 has now reached EOL.

We need to make a decision as to whether we should adopt v5 or move to something else. This work also should be undertaken with the understanding that we'll be moving to React ASAP.

Requirements gathering & R&D should be carried out & discussed before any solution is worked on.

Requirements:

• Have support for code editing (and remove need for Ace editor). Specific needs are JSON, JS and LESS/CSS [optional]

Maybe Quills could be an option to investigate further? It has

• a permissive BSD 3-Clause "New" or "Revised" License (see https://github.com/quilljs/quill/blob/develop/LICENSE) ¨
• more stars on Github (37.7 k) than CKEditor (7.8 k) and TinyMCE (13.8 k) together.
• a react component ready available: https://www.npmjs.com/package/react-quill

It seemed a bit quiet around the project but there seems to be a new version around the corner: Release Version 2.0.0-beta.0 · quilljs/quill (github.com)

I am not affiliated with the project. I just wanted to share some thoughts of an analysis for another project.

Thanks for the recommendation @tomgross, I don't have any experience with modern editors, but I've also heard that Quills is good. There's also a lot of positive noise around Tiptap, which I'll also investigate.

As a stop-gap, I'm going to get CKEditor v5 working (as it seems like the path of least resistance at this point in time). This'll give us a bit of breathing room to let us do the work on upgrading Scaffold to React & research all the editor components we'll need.

Notes

• Custom enter mode has been removed completely, a <p> is always created for a new paragraph
