I love Editor.js. It’s a nice simple block editor that I use to write these posts. It has a host of good plugins that enable you to extend the capabilities of the editor, such as the SimpleImage tool that allows you to add images to the editor without having to upload them. It’s the SimpleImage that I briefly want to talk about. It’s a good tool, but it has two problems, 1) I can only drag images on to the editor, I can’t “add” an image; 2) It uses base64 data URL’s to host the image, this is a waste of memory and it should be using blob URLs.
