canvas-component-utils（画布组件实用程序）

Import utilities from the drupal-canvas package:

import { FormattedText, Image } from 'drupal-canvas';

FormattedText

Use FormattedText to render HTML content from props. This is required for any prop with contentMediaType: text/html in component.yml.

# component.yml
props:
  properties:
    text:
      title: Text
      type: string
      contentMediaType: text/html
      x-formatting-context: block
      examples:
        - <p>This is <strong>formatted</strong> text.</p>

import { FormattedText } from 'drupal-canvas';

const Text = ({ text, className }) => (
  <FormattedText className={className}>{text}</FormattedText>
);

When to use FormattedText:

• Props that accept rich text/HTML content
• Any prop with contentMediaType: text/html
• Content that may contain <p>, <strong>, <em>, <a>, or other HTML tags

Do NOT use FormattedText for:

• Plain text props (type: string without contentMediaType)
• Headings or titles (use regular elements)

Image

Use Image for responsive image rendering. It handles responsive behavior and optimization automatically. The component contract should accept a single image object prop that matches $ref: json-schema-definitions://canvas.module/image; do not split that data into separate imageUrl/imageAlt props.

# component.yml
props:
  properties:
    image:
      title: Image
      type: object
      $ref: json-schema-definitions://canvas.module/image
      examples:
        - src: https://example.com/photo.jpg
          alt: Description of image
          width: 800
          height: 600

import { Image } from 'drupal-canvas';

const Card = ({ image }) => {
  if (!image?.src) return null;

  const { src, alt, width, height } = image;
  return (
    <Image
      src={src}
      alt={alt}
      width={width}
      height={height}
      className="w-full rounded-lg object-cover"
    />
  );
};

Image props:

• src - Image URL (required)
• alt - Alt text for accessibility (required)
• width - Original image width
• height - Original image height
• className - Tailwind classes for styling
