codemirror-ot

Real-time collaboration plugin for CodeMirror 6. For background & writeup, see Medium: Codemirror 6 Experiments. Overhauled in May 2022 to work with the latest CodeMirror 6 APIs and JSON1. A fully functioning collaborative editor that leverages this library can be found in VZCode.

At its core this library is a translator between Operational Transformation and CodeMirror 6. This is one piece of the puzzle for enabling real-time collaboration on text documents using CodeMirror and ShareDB.
