Drupal Canvas Code Components

Canvas Code Components enable interactive, server-side-rendered components in Drupal using modern JavaScript patterns with full Drupal integration.

When This Skill Activates

Activates when working with:

• Canvas Code Components (creation, configuration, styling)
• @drupal-canvas/create scaffolding tool
• Nebula starter template
• Acquia Source Site Builder integration
• Component-based Drupal architecture

Quick Start

Scaffold a New Canvas Project

npx @drupal-canvas/create my-project

This creates a complete Drupal project with Canvas Code Components pre-configured, including:

• Drupal core with Canvas module
• Example components
• Development tooling
• Nebula starter template

What Are Code Components?

Code Components are Drupal's approach to interactive, reusable UI components that:

• Server-side rendered — Full SSR with hydration, not client-only
• Drupal-integrated — Access entities, fields, views, and Drupal APIs
• Composable — Nest components, pass props, emit events
• Styled — Scoped CSS with design token support
• Type-safe — Full TypeScript support with prop validation

Component Structure

my-component/
├── my-component.component.tsx   # Component logic
├── my-component.metadata.json   # Drupal integration metadata
├── my-component.styles.css      # Scoped styles
└── my-component.utils.ts        # Optional utilities

Example Component

import { type ComponentProps } from '@drupal-canvas/sdk';

export default function MyComponent({ title, items }: ComponentProps) {
  return (
    <div className="my-component">
      <h2>{title}</h2>
      <ul>
        {items.map((item, i) => (
          <li key={i}>{item.label}</li>
        ))}
      </ul>
    </div>
  );
}
