devel/py-pycrdt-websocket 0.15.4 DragonFly

Pycrdt-websocket is a Python library for building WebSocket servers and clients that connect and synchronize shared documents. It can be used to create collaborative web applications.

The following diagram illustrates a typical architecture. The goal is to share a document among several clients.

Each client has an instance of a Doc, representing their view of a document. A shared document also lives in a room on the server side. Conceptually, a room can be seen as the place where clients collaborate on a document. The WebSocket to which a client connects points to the corresponding room through the endpoint path. In the example below, clients A and B connect to a WebSocket at path room-1, and thus both clients find themselves in a room called room-1. All the Doc synchronization logic is taken care of by the WebsocketProvider.

Each update to a shared document can be persisted to disk using a store, which can be a file or a database.
