How to use vue in vscode

In recent years, the Vue framework in the field of front-end development has become increasingly popular and has become an irreplaceable part of Web development. For front-end development, choosing an excellent code editor is very important. Among them, Visual Studio Code (hereinafter referred to as VS Code) is undoubtedly the first choice of many front-end developers. So, how to use the Vue framework in VS Code? This article will introduce it to you.

Step One: Install VS Code and Vue.js

First, you need to download and install VS Code, which is available on its official website https://code.visualstudio.com /. Secondly, you also need to install Node.js and Vue.js on your computer. Enter:

node -v

in the command line to check whether Node.js has been installed. If not, you can download and install it from the official website https://nodejs.org/en/. Next, you can install Vue.js via the following command:

npm install vue

Step 2: Use the Vue extension

In VS Code, you can have Global configuration and syntax checking of the Vue framework. Open VS Code and press Ctrl Shift X to enter the extension options. Enter the three letters "Vue" in the search bar and install the Vue extension. At this point, you will see the "Vue" option added to the left menu bar. Click this option and you can set up and manage the Vue framework.

Step 3: Create a Vue project

After installing the above configuration, in order to start using the Vue framework, we first use the Vue-cli scaffolding tool to create a Vue project.

Install Vue-cli using the following command:

npm install -g @vue/cli

When creating a project, you can create it through the presets provided by Vue-cli, or you can configure it manually. Here I use the default configuration and execute the following command line:

vue create vue-test

Wait for a while, enter the following two commands, and then press Enter:

cd vue-test
npm run serve

Display "Compiled successfully" in the console , you can open the browser and visit http://localhost:8080. When you see the page as shown below, a Vue project is successfully created.

Step 4: Use Vue components

In Vue, components are defined through HTML, mainly to improve the reusability of code. In VS Code, you can separate your HTML code into different files by using Vue components, so you can better organize your code. Here, I show you how to create a Vue component.

First, create a new folder, named "Components", and create a file named "Hello.vue" under the folder:

<template>
  <div>
    <h1>{{title}}</h1>
    <h2>{{message}}</h2>
  </div>
</template>

<script>
export default {
  name: 'Hello',
  data () {
    return {
      title: 'Welcome to the Vue World!',
      message: 'Vue is Awesome!'
    }
  }
}
</script>

After creating the component, we This component needs to be added to our Vue root instance. In the "App.vue" file, add the following code:

<template>
  <div id="app">
    <Hello></Hello>
  </div>
</template>

<script>
import Hello from './components/Hello.vue'

export default {
  name: 'App',
  components: {
    Hello
  }
}
</script>

After printing and confirming, run the project and you will see the output "Hello World" as shown in the figure below.

Step 5: Use the Vue debugger

In VS Code, users can use "Vue DevTools" to view the status of Vue components during the development process, which is useful for quickly troubleshooting code errors. Very helpful. In our example here, we use the Chrome browser to view the Vue component status. Please install the Chrome browser. Open Vue DevTools on Chrome browser and you can view the status of Vue components and built apps.

Open Vue DevTools in Chrome browser, click on any component, you will see the data and calculated properties of the component.

At this point, you have completed the tutorial on how to use the Vue framework in VS Code. Hope this article can be helpful to you. In your development process, I hope to use Vue.js for more attempts and practices!
