Editor.js is a block-styled editor for rich media stories. It outputs clean data in JSON instead of heavy HTML-markup. And more important thing is that Editor.js is designed to be API extendable and pluggable.
So there are few key features:
- Clean data output
- API pluggable
- Open source
What does it mean block-styled
In other editors the workspace is provided by single content editable element in where you can create different HTML markup. All of us saw permanent bugs with moving text fragments or scaling images, while page parts are jumping and twitches. Or highlighting big parts of text in case when you just want to make few words to be a heading or bold.
Editor.js workspace consists of separate Blocks: paragraphs, headings, images, lists, quotes, etc. Each of them is an independent content editable element (or more complex structure) provided by Plugin and united by Editor's Core.
At the same time, most useful features as arrow-navigation, copy & paste, cross block selection and others works almost as in the familiar editors.
