Examples to explain how to build vue3 environment and projects

Vue is a popular JavaScript framework that provides powerful reusability and easy-to-maintain code structure through componentization. Vue3 is the latest version of the Vue framework and has been significantly improved in performance and experience. In this article, we will introduce how to set up a Vue3 environment and create a simple Vue3 application.

Step 1: Install Node.js

Before setting up the Vue3 environment, you need to install Node.js first. Node.js is an open source environment for running JavaScript code. It uses the V8 engine built into the Google Chrome browser. You can download and install the latest version from the Node.js official website.

Step 2: Install Vue-CLI

Vue-CLI is Vue’s official scaffolding tool, which can quickly create a Vue-based project. Vue-CLI can be easily installed using npm, the package manager that comes with Node.js.

Open the terminal (Mac users) or command prompt (Windows users) and enter the following command:

npm install -g @vue/cli

This command will install Vue-CLI globally.

Step 3: Create a Vue3 project

Creating a Vue3 project is very simple. Open a terminal or command prompt, enter any path you like, and then run the following command:

vue create my-project

This command will create a Vue3 project named "my-project". In the next steps, you will need to enter some information to configure it.

Step 4: Install Vue3

Use npm to install Vue3:

npm install vue@next

This command will install Vue3.

Step 5: Run the Vue3 application

To run the Vue3 application, you need to enter the project directory and run the following command:

npm run serve

This command will start a development server, Enables you to preview your Vue3 application in the browser.

Step 6: Create a Vue3 component

In Vue3, components are the basic building blocks of code. Let's create a simple Vue3 component. In your project, find the "src/components" folder and create a new file called "HelloWorld.vue".

Add the following code to "HelloWorld.vue":

<template>
  <div>
    <h1>{{ message }}</h1>
  </div>
</template>

<script>
export default {
  name: 'HelloWorld',
  data() {
    return {
      message: 'Hello Vue 3!'
    }
  }
}
</script>

This component will contain a data attribute ("message") and use it to display a title.

Step 7: Use the component in the Vue3 application

Now, let us use the newly created "HelloWorld" component in the Vue3 application. In the "src/App.vue" file, add the following code to the
