I really like EditorJS. It's let me create a very simple web-hosted interface for my static Hugo blog. EditorJS has most of what I need in a simple block-based editor. It has a plugin for headers, code, and even a simple way to add images to the editor without requiring hosting infrastructure. It doesn't have a simple way to add video's to the editor, until now. I took the simple-image plugin repository and changed it up (just a tad) to create a simple-video plugin (npm module).
