Prerequisites#

Before you begin, make sure you have the following:

  • Node.js v20+ and npm installed locally – Download Node.js
  • A supported browser – Chrome 114+, Edge 114+, Firefox 115+, Safari 15.6+
    See Browser Support for the full list.

Existing Project

Get Started#

Create a new React application with QR Code Editor integration.

Step 1: Create a New Project#

Terminal
npm create vite@latest your-project-name — —template react-ts
cd your-project-name
npm create vite@latest your-project-name — —template react-ts
cd your-project-name

Step 2: Clone the Starter Kit#

Clone the starter kit and copy the editor configuration to your project:

Terminal
git clone https://github.com/imgly/starterkit-qr-code-editor-ts-web.git
cp -r starterkit-qr-code-editor-ts-web/src/imgly ./src/imgly
rm -rf starterkit-qr-code-editor-ts-web
git clone https://github.com/imgly/starterkit-qr-code-editor-ts-web.git
cp -r starterkit-qr-code-editor-ts-web/src/imgly ./src/imgly
rm -rf starterkit-qr-code-editor-ts-web

Step 3: Install Dependencies#

Install the required packages for the editor:

Core Editor#

Install the Creative Editor SDK:

Terminal
npm install @cesdk/cesdk-js
npm install @cesdk/cesdk-js

QR Code Plugin#

Add QR code generation:

Terminal
npm install @imgly/plugin-qr-code-web
npm install @imgly/plugin-qr-code-web
  • @imgly/plugin-qr-code-web – CE.SDK plugin that integrates QR code generation into the editor UI (canvas menu and dock panel)

Step 4: Download Assets#

CE.SDK requires engine assets (fonts, icons, UI elements) to function. These must be served as static files from your project’s public/ directory.

Terminal
curl -O https://cdn.img.ly/packages/imgly/cesdk-js/1.73.0/imgly-assets.zip
unzip imgly-assets.zip -d public/
rm imgly-assets.zip
curl -O https://cdn.img.ly/packages/imgly/cesdk-js/1.73.0/imgly-assets.zip
unzip imgly-assets.zip -d public/
rm imgly-assets.zip

Step 5: Create the Editor Component#

Create a React component using the official CE.SDK React wrapper (e.g., QRCodeEditor.tsx):

import { initQRCodeEditor } from './imgly';
import CreativeEditor from '@cesdk/cesdk-js/react';


export default function QRCodeEditor() {
  return (
    <CreativeEditor
      config={{ baseURL: '/assets' }}
      init={initQRCodeEditor}
      style={{ width: '100vw', height: '100vh' }}
    />
  );
}

Step 6: Use the Component#

Import and use the QR Code Editor component in your app:

import QRCodeEditor from './components/QRCodeEditor';


function App() {
  return <QRCodeEditor />;
}


export default App;

Using QR Code Generation#

The editor provides two ways to generate QR codes:

Via Dock Panel#

  1. Click the “QR Code” button in the dock (left sidebar)
  2. The QR Code panel opens with generation options
  3. Enter your URL or text content
  4. Customize colors and size
  5. Click “Generate” to add the QR code to your design

Via Canvas Menu#

  1. Right-click on the canvas
  2. Select “Generate QR Code” from the context menu
  3. The QR Code panel opens for customization

Set Up a Scene#

CE.SDK offers multiple ways to load content into the editor. Choose the method that matches your use case:

src/index.ts
// Create a blank design canvas - starts with an empty design scene
await cesdk.actions.run('scene.create');


// Load from a template archive - restores a previously saved project
await cesdk.loadFromArchiveURL('https://example.com/template.zip');


// Load from an image URL - creates a new scene with the image
await cesdk.createFromImage('https://example.com/image.jpg');


// Load from a scene file - restores a scene from JSON
await cesdk.loadFromURL('https://example.com/scene.json');

The createDesignScene() method is ideal for design workflows, as it creates a blank canvas ready for content.

Customize Assets#

The QR Code Editor uses asset source plugins to provide built-in libraries for templates, stickers, shapes, and fonts. The starter kit includes a curated selection—customize what’s included based on your needs.

Asset sources are added via plugins in src/imgly/index.ts. Enable or disable individual sources:

src/imgly/index.ts
import {
  FiltersAssetSource,
  StickerAssetSource,
  TextAssetSource,
  VectorShapeAssetSource,
  EffectsAssetSource,
  // ...
} from '@cesdk/cesdk-js/plugins';


// Add only the sources you need
await cesdk.addPlugin(new FiltersAssetSource());
await cesdk.addPlugin(new StickerAssetSource());
await cesdk.addPlugin(new TextAssetSource());
await cesdk.addPlugin(new VectorShapeAssetSource());
await cesdk.addPlugin(new EffectsAssetSource());
// ...

For production deployments, self-hosting assets is required—the IMG.LY CDN is intended for development only. See Serve Assets for downloading assets, configuring baseURL, and excluding unused sources to optimize load times.

Configure Actions#

Actions are functions that handle user interactions like exporting designs, saving scenes, and importing files. CE.SDK provides built-in actions that you can run directly or override with custom implementations.

Key built-in actions:

  • exportDesign – Export the current design to PNG, JPEG, PDF, or other formats
  • saveScene – Save the scene as a JSON string for later editing
  • importScene – Import a previously saved scene (supports .scene and .cesdk formats)
  • exportScene – Export the scene as a JSON file or .cesdk archive with all assets
  • uploadFile – Handle file uploads with progress tracking

Use cesdk.actions.run() to execute any action:

// Run a built-in action
await cesdk.actions.run('exportDesign', { mimeType: 'image/png' });

Export and Save#

src/imgly/config/actions.ts
// Register export action that downloads the edited design
cesdk.actions.register('exportDesign', async exportOptions => {
  const { blobs, options } = await cesdk.utils.export(exportOptions);
  await cesdk.utils.downloadFile(blobs[0], options.mimeType);
});

Customize (Optional)#

Theming#

CE.SDK supports light and dark themes out of the box, plus automatic system preference detection. Switch between themes programmatically:

src/imgly/config/settings.ts
// 'light' | 'dark' | 'system' | (() => 'light' | 'dark')
cesdk.ui.setTheme('dark');

See Theming for custom color schemes, CSS variables, and advanced styling options.

Localization#

Customize UI labels and add support for multiple languages. The i18n system supports translation keys for all UI elements:

src/imgly/config/i18n.ts
// Override specific labels
cesdk.i18n.setTranslations({
  en: {
    'actions.export.image': 'Download Design',
    'common.cancel': 'Cancel',
    'common.apply': 'Apply',
  },
});


// Add a new language
cesdk.i18n.setTranslations({
  de: {
    'actions.export.image': 'Design herunterladen',
  },
});


// Set the active locale
cesdk.i18n.setLocale('de');

See Localization for supported languages, translation key reference, and right-to-left language support.

UI Layout#

CE.SDK Editor UI Areas

Customize the editor interface by modifying the dock, inspector bar, navigation bar, and canvas menu. CE.SDK provides Order APIs to control which components appear and in what sequence.

src/imgly/config/ui/navigationBar.ts
// Get current navigation bar components
const navOrder = cesdk.ui.getNavigationBarOrder();


// Add a custom button to the navigation bar
cesdk.ui.insertNavigationBarOrderComponent(
  'ly.img.spacer',
  { id: 'my-custom-action' },
  'after',
);


// Rearrange dock items
cesdk.ui.setDockOrder([
  'ly.img.assetLibrary.dock',
  'ly.img.separator',
  'my-custom-dock-item',
]);

See Dock, Inspector Bar, Navigation Bar, Canvas Menu, and Canvas for detailed layout customization options.

Troubleshooting#

Editor doesn’t load#

  • Check the container element exists: Ensure your container element is in the DOM before calling create()
  • Verify the baseURL: Assets must be accessible from the CDN or your self-hosted location
  • Check console errors: Look for CORS or network errors in browser developer tools

Assets don’t appear#

  • Check network requests: Open DevTools Network tab and look for failed requests to cdn.img.ly
  • Self-host assets for production: See Serve Assets to host assets on your infrastructure

QR code panel doesn’t open#

  • Check plugin installation: Ensure @imgly/plugin-qr-code-web is installed
  • Verify plugin setup: Check that setupQRCodePlugin(cesdk) is called during initialization

Watermark appears in production#

  • Add your license key: Set the license property in your configuration
  • Sign up for a trial: Get a free trial license at img.ly/forms/free-trial
