ℹ️ What is Svelte? Svelte is a UI layer that helps you build user interfaces. However, it has some limitations:
- No built-in router: You can't split your app into different pages
- No server-side rendering (SSR): All code runs only in the browser
- Single-page limitation: Your entire project exists as one big page

SvelteKit is a powerful framework that solves Svelte's limitations. It lets you build full-stack applications with these amazing features:
💡 Tip Think of SvelteKit as Svelte's big brother - it has all of Svelte's powers plus extra superpowers for building complete web applications!
To get started with SvelteKit, access this starter project:
https://stackblitz.com/edit/sveltekit-starter
A SvelteKit project has two main folders you need to know:

📝 Note System Files (Pink in the image)
The pink files and folders contain Node.js packages and SvelteKit settings. You don't need to edit these files as a beginner!
Setting up your project structure:
Create a lib folder inside the src folder
$lib shortcutThe routes folder is special
index.svelte -> homepageabout.svelte -> about pageREADME.md is your project documentation
en/get-startedWant to use Bootstrap's beautiful styles in your SvelteKit project? Here's how to set it up!
Find the app.html file in your src folder. Add this stylesheet link inside the <head> tag:
<link
href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css"
rel="stylesheet"
integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3"
crossorigin="anonymous" />
Add this script tag before the closing </body> tag:
<script
src="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/js/bootstrap.bundle.min.js"
integrity="sha384-ka7Sk0Gln4gmtz2MlQnikT1wXgYsOg+OMhuP+IlRH9sENBO0LRn5q+8nbTov4+1p"
crossorigin="anonymous">
</script>
After adding these two code snippets, you can use all Bootstrap 5 classes in your Svelte components!
💡 Tip Bootstrap Version Note
This tutorial uses Bootstrap 5 (the latest version). If you learned Bootstrap 4 before, don't worry! Most things work the same way, but check the Bootstrap 5 cheat sheet for any differences.
Let's review what you've learned about SvelteKit:
✅ Svelte vs SvelteKit
✅ Key SvelteKit Features
✅ Project Structure
src/ -> Your code lives herestatic/ -> Images and assets go heresrc/lib/ -> Reusable components (create this folder!)src/routes/ -> Your pages✅ Bootstrap Integration
app.html headTry these exercises to reinforce your learning:
Create Your First Route: Add a new file called contact.svelte in the routes folder. What URL will it create?
Component Challenge: Create a Button.svelte component in the lib folder. How would you import it using the $lib shortcut?
Bootstrap Test: After setting up Bootstrap, try adding a Bootstrap button to your index page. Does it work?
Explore the Structure: Look at your project folders. Can you identify which files are system files (that you shouldn't edit) and which are your working files?
