Might make sense to just start with an existing rich text editor (with a friendly license) that you fork. You'll have your own needs but a large part of any editor is common to every other editor. Or maybe you could just spend a few days reviewing the source of existing editors as inspiration. Seems nuts to just go for it yourself especially since OP is saying they aren't super experienced in TS FE.
