You can use create-react-app to setup applications. To create React app use the following command.

npx create-react-app my-app --template typescript
cd my-app
npm start

Adding Syncfusion Diagram package

All Syncfusion react packages are published in the npmjs.com registry. To install the react diagram package, use the following command.

npm install @syncfusion/ej2-react-diagrams --save

Adding CSS references for Diagram

Add CSS references needed for a Diagram in src/App.css from the ../node_modules/@syncfusion package folder.

@import "../node_modules/@syncfusion/ej2-diagrams/styles/material.css";
@import "../node_modules/@syncfusion/ej2-react-diagrams/styles/material.css";
@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-popups/styles/material.css";
@import "../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css";
@import "../node_modules/@syncfusion/ej2-navigations/styles/material.css";

Add Diagram Component

In the src/App.tsx file, use the following code snippet to render the Syncfusion React Diagram control and import App.css to apply styles to the diagram:

import { ConnectorModel, DiagramComponent, NodeModel } from "@syncfusion/ej2-react-diagrams";
import * as React from 'react';
import './App.css';

//Initializes the nodes for the diagram
let nodes: NodeModel[] = [
  {
    id: "begin",
    height: 60,
    offsetX: 300,
    offsetY: 80,
    shape: { type: "Flow", shape: "Terminator" },
    annotations: [
      {
        content: "Begin"
      }
    ]
  },
  {
    id: "process",
    height: 60,
    offsetX: 300,
    offsetY: 160,
    shape: { type: "Flow", shape: "Decision" },
    annotations: [
      {
        content: "Process"
      }
    ]
  },
  {
    id: "end",
    height: 60,
    offsetX: 300,
    offsetY: 240,
    shape: { type: "Flow", shape: "Process" },
    annotations: [
      {
        content: "End"
      }
    ]
  },
];
//Initializes the connector for the diagram
let connectors: ConnectorModel[] = [
  { id: "connector1", sourceID: "begin", targetID: "process" },
  { id: "connector2", sourceID: "process", targetID: "end" },
];

function App() {
    return <DiagramComponent id="container" width={"100%"} height={"350px"} nodes={nodes} connectors={connectors}></DiagramComponent>
};
export default App;

Key features

• Nodes - Nodes are used to host graphical objects (path or controls) that can be arranged and manipulated on a diagram page. Many predefined standard shapes are included. Custom shapes can also be created and added easily.
• Connectors - The relationship between two nodes is represented using a connector.
• Labels - Labels are used to annotate nodes and connectors.
• Ports - Ports act as the connection points of the node and allows to create connections with only those specific points.
• Interactive features - Interactive features are used to improve the run time editing experience of a diagram.
• Data binding - Generates diagram with nodes and connectors based on the information provided from an external data source.
• Commands - Supports a set of predefined commands that helps edit the diagram using keyboard. It is also possible to configure new commands and key combinations.
• Automatic layout - Automatic layouts are used to arrange nodes automatically based on a predefined layout logic. There is built-in support for organizational chart layout, hierarchical tree layout, symmetric layout, radial tree layout, and mind map layout.
• Overview panel - The overview panel is used to improve navigation experience when exploring large diagrams.
• SymbolPalettes - The symbol palette is a gallery of reusable symbols and nodes that can be dragged and dropped on the surface of a diagram.
• Rulers - The ruler provides horizontal and vertical guides for measuring diagram objects in diagram component.
• Serialization - When saved in JSON format a diagram’s state persists, and then it can be loaded back using serialization.
• Exporting and Printing - Diagrams can be exported as .png, .jpeg, .bmp, and .svg image files, and can also be printed as documents.
• Gridlines - Gridlines are the pattern of lines drawn behind diagram elements. It provides a visual guidance while dragging or arranging the objects on a diagram surface.
• Page layout- The drawing surface can be configured to page-like appearance using page size, orientation, and margins.
• Context menu - Frequently used commands can easily be mapped to the context menu.
