SyncedStore CRDT – build multiplayer collaborative apps for React / Vue

In plain words

SyncedStore CRDT is a library for building real-time collaborative applications with React and Vue. It uses conflict-free replicated data types (CRDT) to sync data across multiple users without requiring constant server coordination. Developers can use it to create multiplayer features where changes automatically merge across clients. The tool is designed for web developers building collaborative apps that need offline support and seamless synchronization.

SyncedStore is a library for building distributed, real-time collaborative web applications that sync automatically. This used to be quite complex, but with SyncedStore it's as easy as sharing a pie! It adds an easy-to-use API on top of modern CRDT technology (see below) to make developing multiplayer (or multi-device) experiences just as simple as developing regular applications. // add a todo store . todos . push ( { completed : false , title : "Get groceries" } ) ; // set todo to completed store . todos [ 0 ] . completed = true ; Tip: jump straight into the examples You can walk through the documentation page-by-page, but if you're curious, you might want to jump straight into the live…from syncedstore.org

  Matrix-CRDT – real-time collaborative apps using Matrix as backend2022 · github.com · ▲320

  Hi HN! Matrix-CRDT connects the worlds of Yjs [1] (a proven, high performance CRDT) with that of Matrix.org [2]. It started as an experiment, asking myself; can we store "state updates of a datastore" in Matrix instead of chat messages? Now, I'm convinced it's actually a really powerful combination to develop real-time, collaborative software. I'm using it for a new project and so far didn't have to write a backend yet. Matrix takes care of a lot of stuff: Authentication, E2EE, federation, hosting, etc. - so I can focus on the client. I love the ideas of Local First [3] software. Personally,…

  Pg_CRDT – an experimental CRDT extension for Postgres2022 · supabase.com · ▲296

  This is an experimental extension for CRDTs, pg_crdt: GitHub repo[0]. It supports Yjs/Yrs and Automerge. The linked blog post [1] describes how we're thinking about this extension in a Supabase context. I want to emphasise this part: "pg_crdt has not been released onto the Supabase platform (and it may never be). We’re considering many options for offline-sync/support and, while CRDTs will undoubtedly factor in, we’re not sure if this is the right approach."
