How does Slate compare to draft in package size? I find that including Draft for simple simple simple WYSIWYG editing to be enormous. I don't have the exact size on me, but it made my bundle huuge
For super simple WYSIWYG editing, like I mentioned, you're not going to want to use Slate. (Or maybe Draft either.)
Slate is designed for much more advanced use cases. Things like building wiki tools, or chat tools, or anything where the editing experience itself is a significant enough portion of your product that you want total control over it, and don't want to be constrained by the opinions that most editing frameworks bake into their core libraries.
