ProseMirror is a well-behaved rich semantic content editor based on contentEditable, with support for collaborative editing and custom document schemas.
The ProseMirror library consists of a number of separate modules.
ProseMirror tries to bridge the gap between Markdown text editing and classical WYSIWYG editors. It provides a set of tools and concepts for building rich text editors, using user interface inspired by what-you-see-is-what-you-get, but trying to avoid the pitfalls of that style of editing.
ProseMirror defines its own data structure to represent content documents.
Features include:
- Built-in, ground-up, rock solid support for collaborative editing, where multiple people work on the same document in real time.
- Modular architecture makes sure you only load the code you need, and can replace parts of the system as needed.
- Largely functional and immutable architecture makes it easy to integrate ProseMirror into modern web apps, and confidently implement complex behavior.
- Document schemas allow editing documents with a custom structure without writing your own editor from scratch.
- Plugin system allows you to easily enable additional functionality, and package your own extensions in a convenient format. Some are relatively simple, like the keymap plugin that binds actions to keyboard input. Others are more involved, like the history plugin which implements an undo history by observing transactions and storing their inverse in case the user wants to undo them.
- Core library is small and generic, providing a base onto which very different types of editors can be built. The core library is not an easy drop-in component — modularity and customization are prioritized over simplicity.
