Introduction

This site documents CRDT in Dart — a workspace of small, composable packages for building local-first, collaborative apps on top of Conflict-free Replicated Data Types:

• crdt_lf — the core CRDT library (documents, handlers, changes, snapshots).
• crdt_lf_flutter — Flutter reactivity bindings.
• crdt_socket_sync — client/server synchronization over sockets, with a presence/awareness plugin.
• crdt_lf_sqlite / crdt_lf_drift / crdt_lf_hive — persistence adapters.
• hlc_dart — hybrid logical clock.

Each package's page under Packages is its README — the authoritative, always-up-to-date reference.

New to CRDTs?

If you're not yet comfortable with what CRDTs are and why they matter, start here: I wrote a post that introduces the topic from the ground up — the problem they solve, the intuition behind them, and how the pieces fit together.

Read it first if the concept is new to you; the package docs below assume the basics.

Once the idea clicks, head to the Packages section to pick the bricks you need.

The References section contains a continuously updated list of scientific texts and academic papers that go into greater detail on the topic. But don't worry—you don't need to be familiar with them to use this system, though you do need to be to build it! That's why the fundamentals on which the entire system is based are referenced.
