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 tag:
<template>
<div>
<HelloWorld />
</div>
</template>
<script>
import HelloWorld from './components/HelloWorld.vue'
export default {
name: 'App',
components: {
HelloWorld
}
}
</script>Now run the "npm run serve" command to start the development server and view your Vue3 application. You will see a title that says "Hello Vue 3!"
Summary:
By following the above steps, you have successfully set up a Vue3 environment and created a simple Vue3 app. This is just the tip of the iceberg of the Vue3 framework. You can learn more and experience more features in the Vue3 official documentation. I wish you a happy journey!
