Yorkie is an open source document store for building collaborative editing applications. Yorkie uses JSON-like documents(CRDT) with optional types.
Yorkie consists of three main components: Client, Document and Server.
Client "A" (Go) Self-Hosted Server Or Cloud MongoDB or MemDB

- Clients can have a replica of the document representing an application model locally on several devices.
- Each client can independently update the document on their local device, even while offline.
- When a network connection is available, the client figures out which changes need to be synced from one device to another, and brings them into the same state.
- If the document was changed concurrently on different devices, Yorkie automatically syncs the changes, so that every replica ends up in the same state with resolving conflict.
Full, comprehensive documentation is available on the Yorkie website.
