Using JSX in a Vite Project

1. Introduction

Goal of the tutorial

This tutorial aims to provide a comprehensive understanding of how to use JSX in a Vite project.

Learning outcomes

By the end of this tutorial, you will be able to:
- Understand the basics of JSX
- Setup Vite project
- Use JSX in a Vite project
- Create React components using JSX

Prerequisites

Basic knowledge of JavaScript, React, and understanding of web development concepts is required.

2. Step-by-Step Guide

Concept of JSX

JSX stands for JavaScript XML. It is a syntax extension for JavaScript, which allows us to write HTML in React. JSX makes it easier to write and add HTML in React.

Setting up a Vite project

First, install create-vite by running npm init vite@latest in your terminal. Then, select the react preset and provide a name for your project.

Using JSX in Vite

Once your Vite project is set up, navigate to the src directory. Here, you'll find an App.jsx file. This file is where you'll write your JSX code.

Creating React components

With JSX, you can define your React component and render HTML-like code in your JavaScript files.

3. Code Examples

Example 1: Simple JSX code in React component

// App.jsx

import React from 'react';

function App() {
  return (
    <div className="App">
      <h1>Hello, Vite and JSX!</h1>
    </div>
  );
}

export default App;

In this code snippet,
- We import the React library.
- Define a functional component App.
- Inside the App component, we return JSX code in the form of HTML-like tags.
- We then export the App component.

Example 2: Using JSX to handle events

// App.jsx

import React from 'react';

function App() {
  const handleClick = () => {
    alert('Button clicked!');
  };

  return (
    <div className="App">
      <button onClick={handleClick}>Click me!</button>
    </div>
  );
}

export default App;

In this example,
- We define an event handler handleClick that alerts a message when the button is clicked.
- We then assign this handler to the button's onClick attribute.
