✨ Loro 1.0 is out! Read the announcement.
Loro is a [CRDTs(Conflict-free Replicated Data Types)](https://crdt.tech/) library that makes building [local-first][local-first] and collaborative apps easier. You can now use it in Rust, JS (via WASM), and Swift.
# Features
**Features Provided by CRDTs**
- P2P Synchronization
- Automatic Merging
- Local Availability
- Scalability
- Delta Updates
**Supported CRDT Algorithms**
- Text Editing with [Fugue]
- [Rich Text CRDT](https://loro.dev/blog/loro-richtext)
- [Moveable Tree](https://loro.dev/docs/tutorial/tree)
- [Moveable List](https://loro.dev/docs/tutorial/list)
- ️ [Last-Write-Wins Map](https://loro.dev/docs/tutorial/map)
- Mergeable map-key children via `ensureMergeable*` / `ensure_mergeable_*` for lazy child container creation
**Advanced Features in Loro**
- [Fast Document Loading](https://loro.dev/blog/v1.0)
- ⏱️ Fast [Time Travel](https://loro.dev/docs/tutorial/time_travel) Through History
- ️ [Version Control with Real-Time Collaboration](https://loro.dev/blog/v1.0#version-control)
- [Shallow Snapshot](https://loro.dev/docs/advanced/shallow_snapshot) that Works like Git Shallow Clone

> In this example, we demonstrate importing an entire Loro codebase into a Loro-powered
> version controller, preserving the complete Git DAG history while enabling fast version switching.

# Credits
Loro draws inspiration from the innovative work of the following projects and individuals:
- [Diamond-types](https://github.com/josephg/diamond-types): The [Event Graph Walker (Eg-walker)](https://loro.dev/docs/advanced/event_graph_walker) algorithm from @josephg has been adapted to reduce the computation and space usage of CRDTs.
- [Automerge](https://github.com/automerge/automerge): Their use of columnar encoding for CRDTs has informed our strategies for efficient data encoding.
- [Yjs](https://github.com/yjs/yjs): We have incorporated a similar algorithm for effectively merging collaborative editing operations, thanks to their pioneering work.
- [Matthew Weidner](https://mattweidner.com/): His work on the [Fugue](https://arxiv.org/abs/2305.00583) algorithm has been invaluable, enhancing our text editing capabilities.
- [Martin Kleppmann](https://martin.kleppmann.com/): His work on CRDTs has significantly influenced our comprehension of the field.
