How to Import SVG Files in React Diagram?

This article provides an explanation of how to import SVG files in Syncfusion® React Diagram. The example demonstrates how to add a button to facilitate importing an image from the local system. When the button is clicked, it triggers a file selection dialog that allows users to choose an image from their local storage.

Include the file input element in your HTML, configured to accept only SVG file types:

<input type="file" id="fileUpload" onChange={onFileChange} accept="image/svg+xml" />

Once an image is selected, the application processes the file upload. Then onFileChange method is invoked to handle the upload and add the SVG file as a node to the diagram. The following code, demonstrates how to import SVG files into diagram:

 // function to import svg file to diagram
 const onFileChange = (args) => {
   const file = args.target.files[0];
   if (file) {
     // Create a new FileReader to read the content
     const reader = new FileReader();
     // Define a callback function to execute when the file reading is complete
     reader.onload = (event) => {
       const svgContent = event.target.result;
       // Define the SVG node
       const svgNode = {
         id: 'svgNode',
         offsetX: 250, offsetY: 250,
         width: 200, height: 200,
         shape: {
           type: 'Native',
           content: svgContent  // Set SVG content
         }
       };
       // Add the SVG node to the diagram
       diagramInstance.add(svgNode);
     };
     reader.readAsText(file);
   }
 };
