What is Vite?

Vite is a front-end building tool developed by Evan You (the founder of Vue.js). Its name comes from the French word "vitesse" meaning speed. Vite is designed to provide extremely fast development and build speeds, providing a faster development experience for front-end developers.

Vite’s core features

1. Quick cold start

Vite takes advantage of the ES module features of modern browsers to achieve ultra-fast cold start speeds in development mode. This means that when you launch a project, you can start writing code almost immediately without waiting for a tedious build process.

2. Import on demand

Vite supports importing modules on demand, which means it will only load modules when you actually need them. This can significantly reduce the amount of redundant code during development and construction and improve application performance.

3. Fast hot update

Vite enables fast hot updates through HMR (Hot Module Replacement) without the need to refresh the entire page. This allows you to perform live code editing and debugging while maintaining application state.

4. Multiple module system support

Vite supports multiple module systems, including ES modules, CommonJS, AMD, etc., allowing you to freely choose and mix different module systems in your project.

Create a simple Vue.js application using Vite

Let's use a simple example to demonstrate how to create a Vue.js application using Vite.

Step 1: Install Vite

First, make sure you have Node.js installed. Then, run the following command in the terminal to install Vite globally:

npm install -g create-vite

Step 2: Create a new project

Create a new Vite project:

create-vite my-vue-app

Step 3: Enter the project directory

cd my-vue-app

Step 4: Install dependencies

Run the following command to install the project's dependencies:

npm install

Step 5: Run the application

Now, run the following command to start the development server:

npm run dev

Step 6: Create a Vue component

srcCreate a file named in the folder in the project root directory HelloWorld.vuewith the following content:

<template>
  <div>
    <h1>Hello, Vite!</h1>
  </div>
</template>

<script>
export default {
  name: 'HelloWorld',
}
</script>

<style scoped>
h1 {
  color: #42b983;
}
</style>

Step 7: Use the component in the main app

In a file srcin the folder main.js, import and use HelloWorldthe component:

import {
    
     createApp } from 'vue'
import App from './App.vue'
import HelloWorld from './HelloWorld.vue'

const app = createApp(App)
app.component('HelloWorld', HelloWorld)
app.mount('#app')

Step 8: Run the application

Now, you can access it in your browser http://localhost:3000and see your Vue.js application running!

in conclusion

Vite is a powerful front-end building tool that provides fast cold start, on-demand import, fast hot update and other features, which greatly improves the front-end development experience.
