Collaborative Editing in React Spreadsheet component

The collaborative editing support allows you to work at a spreadsheet collaboratively with other users. Multiple users can access to the the same spreadsheet simultaneously.

  • To use Collaborative editing, inject the CollaborativeEditing module in the spreadsheet.

Dependencies

The following list of dependencies are required to use the collaborative editing support in spreadsheet.

|-- @aspnet/signalr
   |-- eventsource
   |-- request
   |-- ws
  • Run the command npm i @aspnet/signalr to install @aspnet/signalr packages in your application.

Server configuration

To make the communication between the server to the connected clients and from clients to the server, you need to configure the signalR Hubs using the following code.

import * as signalR from '@aspnet/signalr';

// For signalR Hub connection
    public connection = new signalR.HubConnectionBuilder().withUrl('https://ej2services.syncfusion.com/production/web-services/hubs/spreadsheethub', {
        skipNegotiation: true,
        transport: signalR.HttpTransportType.WebSockets
    }).build();

Client configuration

To broadcast the data for every action is spreadsheet, you need to transfer the data to the server through send method in actionComplete event and receive the same data by using the dataReceived method. In the dataReceived method, you need to update the action to the connected clients through updateAction method.

The following code example shows Collaborative Editing support in the Spreadsheet control.
