FAQPage Schema
How do I add real-time collaboration and document synchronization to a local-first app?

Real-time collaboration and document synchronization in a local-first app are handled via conflict-free replicated data types, allowing multiple users to edit shared data offline and sync seamlessly. The Loro library implements these CRDT algorithms across Rust, JS, and Swift environments.

What are CRDTs and when do I need them for version control in my application?

CRDTs are conflict-free replicated data types that enable concurrent edits across distributed nodes without central coordination, automatically resolving conflicts mathematically. You need them when building local-first apps requiring reliable version control and data synchronization across offline or unreliable networks.

Does the Loro CRDT library work with JavaScript and Swift, or is it limited to Rust?

Loro supports cross-language integration across Rust, JavaScript via WebAssembly, and Swift environments. It provides specific language bindings and editor integrations, allowing developers to implement local-first synchronization workflows natively in their preferred development stack.

How do I evaluate if a CRDT approach fits my local-first app architecture?

To evaluate if a CRDT approach fits your local-first app architecture, review the architectural fit guide provided in the documentation. This guide helps assess whether your data modeling, synchronization, and versioning requirements align with conflict-free replicated data type constraints.

Can I integrate Loro synchronization with existing code editors like ProseMirror or CodeMirror?

Yes, Loro provides direct editor integrations for ProseMirror and CodeMirror. These bindings allow you to embed real-time collaborative editing and document synchronization capabilities directly into existing text and code editor workflows.

What are the limitations of using CRDTs for local-first version control?

CRDTs for local-first version control require a basic understanding of conflict resolution mechanisms and can introduce metadata overhead. Developers must carefully model data structures to fit CRDT constraints, which may complicate complex schema migrations.
