Setting Up a Svelte/Vite Project

1. Introduction

The purpose of this tutorial is to guide you in setting up a new web development project using Svelte, a powerful JavaScript framework, and Vite, a fast, modern build tool. By the end of this tutorial, you will have a new Svelte/Vite project set up and ready for development.

Prerequisites for this tutorial include basic knowledge of JavaScript and familiarity with the command-line interface.

2. Step-by-Step Guide

First, we need to install Node.js and npm (Node Package Manager) on your machine. Node.js is a JavaScript runtime that allows you to run JavaScript on your server or your machine. npm is a package manager for JavaScript, and default for Node.js.

You can download Node.js and npm from here.

After installing Node.js and npm, you can verify the installation by running the following commands:

node -v
npm -v

You should see the versions of Node.js and npm print out.

Now, let's install the create-vite package globally using npm:

npm install -g create-vite

Once installed, you can use create-vite to create a new Vite project:

npx create-vite my-svelte-project --template svelte

After that, navigate into your new project directory:

cd my-svelte-project

And install the project dependencies:

npm install

To start the development server, run:

npm run dev

You should see the Vite development server starting up. Now, navigate to http://localhost:5000 in your web browser. You should see your new Svelte/Vite project running!

3. Code Examples

Let's create a simple Svelte component. Inside your src directory, create a new file named Greeting.svelte:

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

<h1>Hello {name}!</h1>

<input bind:value={name}>

In this component, we have a variable name that is bound to an input field. When you type into the input field, the name variable is updated and the greeting is updated in real time.

To use this component, include it in your App.svelte:

<script>
  import Greeting from './Greeting.svelte';
</script>

<main>
  <Greeting />
</main>

When you save and go to your browser, you should see the greeting and an input field. Try typing into the input field and watch the greeting update!

4. Summary

In this tutorial, we covered how to set up a new Svelte/Vite project, how to create a simple Svelte component, and how to use it in your application.

For further learning, you can explore more about Svelte's reactivity and state management, routing, and how to build and deploy your Svelte/Vite application.

5. Practice Exercises

1. Create a Svelte component that displays a list of names. The names should be stored in an array in the component's script tag.

2. Modify the component from exercise 1 to include an input field and a button. When the button is clicked, the name in the input field should be added to the list.

3. Create a Svelte component that fetches data from a public API and displays it. You can use the JSONPlaceholder API for this exercise.

For further practice, try building a simple application like a to-do list or a note-taking app. Try to incorporate different Svelte features and concepts as you build. Happy coding!
