# Shape Element

## Content

Using the Shape element in SpreadJS with React, you can quickly embed and render various shapes including geometric figures like squares, circles, rectangles, triangles, pentagons, hexagons, octagons, etc. in the worksheets without any hassle.

1. **Create a React Project**
    Open the Command Prompt window and type the following commands:

    ```Shell
    npm install -g create-react-app
    create-react-app quick-start
    cd quick-start
    npm start
    ```

    After you finish, the react project will be created at the specified location in the directory. For more information on how to create a React project, refer to [https://reactjs.org/docs/create-a-new-react-app.html](https://reactjs.org/docs/create-a-new-react-app.html).
2. **Install SpreadJS React module in project**
    Next, you need to install @grapecity/spread-sheets-react in your project using the following command:

    ```Shell
    npm install @grapecity/spread-sheets-react
    ```
3. **Import SpreadJS CSS**
    Next, you need to import the SpreadJS CSS in your index.js file using the following code:

    ```JavaScript
    import '@grapecity/spread-sheets/styles/gc.spread.sheets.excel2013white.css';
    ```
4. **Install Shapes React Module in the Project**
    Next, you need to install the shapes module in your project using the following command:

    ```Shell
    npm install @grapecity/spread-sheets-shapes
    ```
5. **Use Shapes in React Application**
    Now, you can modify the App.js file as per your requirements. Changes will be reflected when the browser window is refreshed. As an example, you can use the sample code given below:
    This example shows how to use shapes in a React Application.

    ```JavaScript
    import React from "react";
    import "./App.css";
    import GC from "@grapecity/spread-sheets";
    import { SpreadSheets, Worksheet } from "@grapecity/spread-sheets-react";
    
    // Import Shapes module
    import "@grapecity/spread-sheets-shapes";
    
    var SpreadJSKey = "xxx";
    GC.Spread.Sheets.LicenseKey = SpreadJSKey;
    
    class App extends React.Component {
      constructor(props) {
        super(props);
        this.hostStyle = {
          width: "1100px",
          height: "800px",
        };
      }
    
      // Handling workbook initialized event
      workbookInit = (spread) => {
        this.setState({
          spread: spread,
        });
    
        // Fetching sheet
        let sheetShape = spread.getSheet(0);
    
        // Setting Sheetname
        sheetShape.name("Shapes");
        sheetShape.suspendPaint();
    
        // Add built-in shape "donut"
        var donutShape = sheetShape.shapes.add(
          "autoShape",
          GC.Spread.Sheets.Shapes.AutoShapeType.donut,
          50,
          50,
          150,
          150
        );
    
        // Adding text to built-in shape "donut"
        donutShape.text("Donut Shape");
    
        // Adding style to built-in shape "donut"
        var shapeStyle = donutShape.style();
        shapeStyle.textEffect.color = "Red";
        shapeStyle.textEffect.font = "18px Arial";
        shapeStyle.textFrame.hAlign = GC.Spread.Sheets.HorizontalAlign.center;
        shapeStyle.textFrame.vAlign = GC.Spread.Sheets.VerticalAlign.center;
        donutShape.style(shapeStyle);
    
        sheetShape.resumePaint();
      };
      render() {
        return (
          <div>
            <SpreadSheets
              backColor={this.spreadBackColor}
              hostStyle={this.hostStyle}
              workbookInitialized={this.workbookInit}
            >
              <Worksheet></Worksheet>
            </SpreadSheets>
          </div>
        );
      }
    }
    
    export default App;    
    ```
