Collabs is a collections library for collaborative data structures. These are data structures that look like
Array, etc., except they are synchronized between multiple users: when one user changes a collaborative data structure, their changes show up for every other user. You can use them to quickly build collaborative apps along the lines of Google Docs/Sheets/Slides, shared whiteboards, etc.
@collabs/collabs is Collabs's main package. It contains Collabs's core and its built-in collaborative data structures, which are all operation-based Conflict-free Replicated Data Types (CRDTs).
