🎯 Key Concepts Demonstrated

One. Component Props

Each component exports variables that become props:

<script>
  export let title;  // This becomes a prop
</script>

2. Component Reusability

The Section.svelte component is used three times with different data:

• Info section
• Hobbies section
• Personality section

This demonstrates the power of reusable components in modern web development.

3. The Spread Operator

Instead of passing each prop individually:

<!-- ❌ Verbose way -->
<Section title={myInfo.title} item1={myInfo.item1} item2={myInfo.item2} item3={myInfo.item3} />

<!-- ✅ Better way with spread operator -->
<Section {...myInfo} />

The spread operator {...myInfo} automatically passes all properties of the object as individual props.

4. Data Objects

Data is organized in objects that match the component props:

let myInfo = {
  title: "Info",
  item1: "Lee Kah Fai",
  item2: 14,
  item3: "SMJK (C) Chung Ling",
}

5. Dynamic Data Binding

The footer uses data from the myInfo object:

<Footer name={myInfo.item1} />

This ensures the name is consistent across the application.

🚀 Getting Started

📝 Implementation Details

Header Component (src/lib/Header.svelte)

• Props: title (string)
• Purpose: Displays the page heading
• Usage: <Header title="My Biography" />

Section Component (src/lib/Section.svelte)

• Props:
  • title (string) - Section heading
  • item1 (string/number) - First item
  • item2 (string/number) - Second item
  • item3 (string/number) - Third item
• Purpose: Reusable component for displaying information sections
• Usage: <Section {...dataObject} />

Footer Component (src/lib/Footer.svelte)

• Props: name (string)
• Purpose: Displays copyright information
• Usage: <Footer name={myInfo.item1} />

Main Page (src/routes/+page.svelte)

• Imports all components
• Defines data objects (myInfo, myHobby, myPersonality)
• Composes the page using imported components
• Demonstrates the spread operator for passing props

🎨 Styling

The project uses Bootstrap 5 for styling, included via CDN in src/app.html:

<link
  href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css"
  rel="stylesheet"
/>

Students can enhance the styling by:

• Adding Bootstrap classes to components
• Using custom CSS in component <style> blocks
• Adding color schemes from Color Hunt

🔧 Customization

To personalize this biography:

1. Update personal information in src/routes/+page.svelte:

   • Change myInfo object with your details
   • Update myHobby with your hobbies
   • Modify myPersonality with your traits

2. Add more sections by creating new data objects:

   javascript

   let mySkills = {
     title: "Skills",
     item1: "JavaScript",
     item2: "Svelte",
     item3: "CSS"
   }
   

3. Enhance styling by adding Bootstrap classes or custom CSS

📚 Learning Outcomes

After studying this solution, students should understand:

• ✅ How to create Svelte components
• ✅ How to export and use props
• ✅ How to import and use components
• ✅ How to structure a SvelteKit project
• ✅ How to use the spread operator with props
• ✅ How to organize data in objects
• ✅ How to reuse components with different data

🎓 Educational Notes

From Svelte REPL to SvelteKit

The original project uses Svelte REPL (online editor) with App.svelte. This solution adapts it to SvelteKit:

• App.svelte -> src/routes/+page.svelte
• Components moved to src/lib/ directory
• Import paths updated (e.g., './Header.svelte' -> '../lib/Header.svelte')
• Bootstrap included in src/app.html instead of component file

Why Use Components?

Components provide several benefits:

1. Reusability: Write once, use many times (see Section.svelte)
2. Maintainability: Update in one place, changes reflect everywhere
3. Organization: Keep code modular and easy to understand
4. Scalability: Easy to add new features without breaking existing code

The Spread Operator Explained

The spread operator {...object} is a JavaScript feature that:

• Takes all properties from an object
• Passes them as individual arguments
• Reduces code repetition
• Makes code more maintainable

Example:

// These two are equivalent:
<Section {...myInfo} />
<Section title="Info" item1="Lee Kah Fai" item2={14} item3="SMJK (C) Chung Ling" />

🔍 Troubleshooting

Common Issues

Components not displaying:

• Check import paths are correct
• Ensure component files are in src/lib/ directory
• Verify component names match in import and usage

Props not working:

• Ensure props are exported in components: export let propName;
• Check prop names match between parent and child
• Verify spread operator syntax: {...object} not {object}

Bootstrap styles not applying:

• Confirm Bootstrap link is in src/app.html
• Check class names are spelled correctly
• Ensure HTML structure supports the Bootstrap class

🌟 Extension Ideas

To enhance this project:

1. Add a photo/avatar section
2. Create a skills section with progress bars
3. Add social media links component
4. Implement theme switcher (light/dark mode)
5. Add animations using Svelte transitions
6. Create a contact form section
