Astro-Specific Features

Component Frontmatter

Use Astro’s frontmatter for logic:

---
const { variant = 'elevated', hoverable = false, ...props } = Astro.props;

const classes = [
  'card',
  `card--${variant}`,
  hoverable && 'card--hoverable'
].filter(Boolean).join(' ');
---

<div class={classes} {...props}>
  <slot />
</div>

Props Interface

Define TypeScript interfaces for props:

---
interface Props {
  variant?: 'elevated' | 'outlined' | 'flat';
  hoverable?: boolean;
  clickable?: boolean;
}

const { variant = 'elevated', hoverable = false, clickable = false } = Astro.props;
---

Slots

Use Astro’s slot system:

<Card>
  <slot name="header" />
  <slot />
  <slot name="footer" />
</Card>

Static by Default

Components render as static HTML with no JavaScript:

<!-- This renders pure HTML/CSS -->
<Card variant="elevated">
  <h2>Static Content</h2>
  <p>No JavaScript needed!</p>
</Card>

Client Directives

Add interactivity when needed:

---
import { Button } from '@primitivekit/astro';
---

<!-- Load JavaScript only when needed -->
<Button client:load onclick="alert('Hello!')">
  Click Me
</Button>

Performance Benefits

• Zero JavaScript by default - Components ship as pure HTML/CSS
• Partial Hydration - Add interactivity only where needed
• Perfect Lighthouse Scores - Optimized for Core Web Vitals
• Fast Page Loads - Minimal bundle size
