About Yjs CRDT
By Toolradar Team·
Yjs is a Conflict-free Replicated Data Type (CRDT) library designed to simplify the creation of collaborative applications. It provides 'Shared Types' that behave like standard data types but automatically synchronize across multiple users in real-time. This allows developers to build interactive, multi-user experiences without complex synchronization logic.
The library offers offline support, enabling applications to function without a constant internet connection and sync data once connectivity is restored. Yjs is also network agnostic, meaning it doesn't require a central server for coordination, promoting decentralized, faster, and more fault-tolerant systems. It integrates with various technologies through a rich ecosystem of bindings for popular editor libraries and web frameworks, connection protocols, and persistence layers, making it a versatile solution for real-time collaboration.
