+# Spreadsheet Collaborative Editing
+
+This repository showcases real-time collaborative editing using the Syncfusion® Spreadsheet Editor, allowing multiple users to edit the same workbook simultaneously. The project demonstrates how to implement collaborative features across multiple frontend frameworks (Angular, React, Vue, and TypeScript) with an ASP.NET Core backend.
+
+## Features
+
+- Real-time collaborative editing of spreadsheets
+- Support for multiple frontend frameworks:
+  - Angular
+  - React
+  - Vue
+  - TypeScript (Vanilla)
+- ASP.NET Core backend with SignalR for real-time communication
+- Redis integration for collaboration state management
+- Spreadsheet operations synchronization across multiple clients
+- Selection highlighting for other users' cursor positions
+
+## Prerequisites
+
+### Backend
+- .NET 10.0 SDK
+- Redis server (for collaboration state management)
+- Syncfusion license key
+
+### Frontend
+- Node.js (v18 or later)
+- npm or yarn

+
+## Setup
+
+### Backend Setup
+
+1. Navigate to the server directory:
+   ```bash
+   cd server/aspnet-core
+   ```
+
+2. Configure your Syncfusion license:
+   - Add your license key to `SyncfusionLicense.txt` file
+   - Or set the `SYNCFUSION_LICENSE_KEY` environment variable
+
+3. Configure Redis connection:
+   - Update the Redis connection string in `appsettings.json`:
+     ```json
+     {
+       "ConnectionStrings": {
+         "Redis": "your_redis_connection_string"
+       }
+     }
+     ```
+
+4. Run the server:
+   ```bash
+   dotnet run
+   ```
+   
+   The server will start on `https://localhost:5001` by default.
+
+### Frontend Setup
+

+   ```bash
+   cd client/angular
+   ```
+
+2. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+3. Update the service URL in `src/components/spreadsheet-editor/spreadsheet-editor.component.ts`:
+   ```typescript
+   const serviceUrl: string = 'https://localhost:5001/';
+   ```
+
+4. Run the application:
+   ```bash
+   npm start
+   ```
+   
+   The application will be available at `http://localhost:4200`.
+
+#### React
+
+1. Navigate to the React client:
+   ```bash
+   cd client/react
+   ```
+
+2. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+3. Update the service URL in `src/SpreadsheetEditorAdapter.ts`:
+   ```typescript
+   const serviceUrl: string = 'https://localhost:5001/';
+   ```
+
+4. Run the application:
+   ```bash
+   npm run dev
+   ```
+   
+   The application will be available at `http://localhost:5173`.

+   cd client/vue
+   ```
+
+2. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+3. Update the service URL in `src/SpreadsheetEditorAdapter.ts`:
+   ```typescript
+   const serviceUrl: string = 'https://localhost:5001/';
+   ```
+
+4. Run the application:
+   ```bash
+   npm run dev

+   cd client/typescript
+   ```
+
+2. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+3. Update the service URL in `src/spreadsheet-editor-adapter.ts`:
+   ```typescript
+   const serviceUrl: string = 'https://localhost:5001/';
+   ```
+
+4. Run the application:
+   ```bash
+   npm run dev
+   ```
+   
+   The application will be available at `http://localhost:5173`.
+
+## Usage
+
+1. Start the backend server
+2. Start one of the frontend clients
+3. Open the application in multiple browser windows or devices
+4. Each user will be assigned a unique room ID automatically
+5. To collaborate in the same room, share the URL with the room ID parameter
+6. All users in the same room will see real-time updates as others edit the spreadsheet
+
+## API Endpoints
+
+The backend provides the following API endpoints:
+
+- `POST /api/CollaborativeEditing/ImportFile` - Import a file for collaborative editing
