As part of my app I needed to allow users to edit content that used BBCode. I’d started out using just a text area, but wanted something with toolbar buttons. I went down the rabbit hole of trying Quill and other editors that show you an in-editor preview, before realizing I just needed a text editor with a separate preview.
What came out of that effort is this: BBCode Editor And Previewer
It’s all undocumented, but shared in the hopes that it might help someone who also needs something between a text area and a full WYSIWYG editor.
As a bonus, it works fine in an Anvil alert.
