js-collaboration-ot

js-collaboration-ot is a collaboration library based on Operational Transformation (OT) technology, designed to enhance the real-time synchronization capabilities of js-collaboration. Through the OT technology, it enables multiple users to edit the same data simultaneously. It is divided into the client side (js-collaboration-ot-client) and the server side (js-collaboration-ot).

Applicable Scenarios

Suitable for applications requiring real-time collaborative editing, including:

Collaborative spreadsheet editing
Rich text co-authoring
Interactive chart collaboration

Core Features

Custom OT Types: Supports developers in defining custom operation types to meet various business needs.
Data Persistence: Provides adapter interfaces for integration with database storage.
Fragment Mechanism (Fragments): Improves synchronization performance for large documents.
Conflict Resolution: Ensures data consistency through the OT algorithm.
Middleware and Hooks: Supports inserting validation, logging, and other logic into the collaboration process.

Design Advantages

Modularity: OT types, middleware, and adapters are independently designed, making customization and extension easy.
Efficiency: The Fragment mechanism reduces I/O overhead for large documents.
Flexibility: Supports asynchronous middleware and diverse databases, adapting to complex business scenarios.
