npx serve

Then open your browser at the provided URL (typically http://localhost:3000).

Image Display

The "fetch image" command now works entirely with JavaScript:

1. You can use it without a URL to get a random image:

   fetch image
   

2. You can provide a specific image URL:

   fetch image https://example.com/image.jpg
   

3. You can also use the shorter image command:

   image https://example.com/image.jpg
   

API Integration

The application can fetch data from any API and will:

• Display JSON responses in a formatted way
• Detect image responses and display them in the canvas
• Handle errors gracefully

Quick API Examples

• JSON data: `fetch https://jsonplaceholder.typicode.com/todos
