Automerge

Automerge is a CRDT library for building local-first collaboration software, allowing several users to concurrently edit a file, both in real-time and offline. It is currently optimized for working on a single document; this project aims to improve Automerge's support for synchronizing large collections of documents across multiple devices (for example, all of a user's notes in a note-taking app). The challenges here are efficiently determining which documents need to be synced, syncing multiple documents in parallel, giving users a progress indicator during large data transfers, and making the protocol efficient in terms of computation, memory, and bandwidth. Our protocol will be compatible with both client-server and peer-to-peer synchronization.
