YDotNet

YDotNet is a .NET binding for y-crdt. It provides distributed data types that enable real-time collaboration between devices. The library is a thin wrapper around Yrs, taking advantage of the safety and performance of Rust.

💡 Disclaimer: this project is still early, so it may contain bugs and the API is subject to change. Feel free to open an issue if you'd like to report problems or suggest new features.

Demo

Installation

For every scenario, you must start by installing the core of the library.

To do so, in the project directory (where you .csproj lives), execute:

dotnet add package YDotNet

Then, install the platform-specific package in order to get the binaries.

And you may also install the following packages to get extra features.

Getting Started

YDotNet provides the same shared data types as Yjs. All objects are shared within a Doc and always get modified within the scope of a Transaction.

// Set up the local document with some sample data.
var localDoc = new Doc();
var localText = localDoc.Text("name");

var localTransaction = localDoc.WriteTransaction();
localText.Insert(localTransaction, 0, "Y-CRDT");
localTransaction.Commit();

// Set up the remote document.
var remoteDoc = new Doc();
var remoteText = remoteDoc.Text("name");

// Get the remote document state vector.
var remoteTransaction = remoteDoc.WriteTransaction();
var remoteState = remoteTransaction.StateVectorV1();

// Calculate the state diff between the local and the remote document.
localTransaction = localDoc.ReadTransaction();
var stateDiff = localTransaction.StateDiffV1(remoteState);
localTransaction.Commit();

// Apply the state diff to synchronize the remote document with the local changes.
var result = remoteTransaction.ApplyV1(stateDiff);

// Read the text from the remote document.
var text = remoteText.String(remoteTransaction);

// At this point, the `text` variable is "Y-CRDT" and this demonstrates how the two
// documents synchronized their state.
//
// This example does it locally but the same could be done over the Internet, for example.

Development Setup

To contribute with this library, you'll need to install the following tools:

• .NET SDK
• Rust

Then you should clone the y-crdt repository. With the repository cloned and the tools installed, you'll be able to:

1. Make changes to the Rust or C# library;
2. Re-build the Rust and C# binaries;
   • Be aware that you'll need to use crate-type=cdylib on the Cargo.toml file to get a dynamic library that's callable by C#.
3. Test your changes and repeat.

Then you're ready to go! Feel free to contribute, open issues, and ask questions.

Tests

All tests are located in the YDotNet.Tests.Unit project and should be easily runnable using the command:

dotnet test
