Does anyone have any experience and can offer a suggestion on javascript libraries that will handle text editing (like google docs or etherpad) and which can be dropped into a site and which aren't locked into a particular service or backend?
[ShareDB](https://github.com/share/sharedb) is the most commonly used, we use it extensively - also has bindings to rich text or code editors. [Y-js](http://y-js.org/) is a more academic project, also based on CRDTs I think.
I.e. basically something like this but for text?
