Vite with Svelte

1. Introduction

Goal of the Tutorial

This tutorial aims to guide you on how to use Vite with the Svelte framework for efficient web development.

Learning Outcomes

By the end of this tutorial, you will learn:
- The basics of Vite and Svelte
- How to set up a project with Vite and Svelte
- Understanding and using Vite features with Svelte

Prerequisites

You should have a basic understanding of:

• JavaScript (ES6)
• Node.js and npm

2. Step-by-Step Guide

What is Vite?

Vite is a modern build tool created by Evan You, the creator of Vue.js. It offers a faster and leaner development experience for modern web projects.

What is Svelte?

Svelte is a radical new approach to building user interfaces. It compiles your code to tiny, framework-less vanilla JS for truly reactive programming.

How to Set Up a Project

1. Install create-vite by running the following command in your terminal:

bash npm init @vitejs/app

1. You will be prompted to select a project name and a template. Choose svelte.

2. Navigate into your new project then install the dependencies:

bash cd my-vite-project npm install

1. Start the development server:

bash npm run dev

Now, your new Vite and Svelte powered application is running at localhost:5000.

3. Code Examples

Hello World in Svelte

Create a new file App.svelte in src directory and write the following code:

<script>
  let name = 'world';
</script>

<main>
  <h1>Hello {name}!</h1>
  <input bind:value={name}>
</main>

• <script> contains the component's state, name in this case.
• <main> contains the HTML template which uses the state. {name} is a reactive statement, meaning it updates whenever the state changes.
• bind:value={name} is a two-way data binding, meaning the state name will update whenever the input changes.

When you navigate to localhost:5000, you should see a heading saying "Hello world!" and an input field. If you type in the input field, the heading will update in real time.

4. Summary

In this tutorial, we have covered the basics of Vite and Svelte, and how to set up a project with them. We have also learned how to create a simple "Hello World" app in Svelte.

For further learning, you can explore more about Vite and Svelte from their official documentation.

5. Practice Exercises

1. Create a new Vite and Svelte project and add a button that, when clicked, changes the text of a paragraph.

2. Create a simple todo app where you can add and delete tasks.

3. Create a simple counter app where you can increment, decrement and reset the count.

Each exercise should help you get more familiar with Vite and Svelte. Try to complete them without looking at the solutions. And remember, practice is key to mastering any programming concept.
