nodejs install vue

Node.js is an open source cross-platform JavaScript running environment. Vue.js is a progressive JavaScript framework with many excellent features, such as two-way data binding, component development, virtual DOM, etc. In modern web applications, Vue.js has become one of the most popular front-end frameworks, and Node.js is an essential environment for Vue development. This article will introduce how to install Vue.js in a Node.js environment.

Step one: Install Node.js

Before installing Vue.js, you must first install the Node.js environment. Node.js can be downloaded and installed from the Node.js official website (https://nodejs.org/). The download page will automatically recommend suitable versions according to different operating systems. Just click to download and follow the prompts to complete the installation.

Step 2: Check whether Node.js is installed successfully

After the installation is complete, open a terminal or command prompt and run the following command to check whether Node.js is installed successfully:

node -v

If the terminal or command prompt outputs the currently installed Node.js version number, it means that Node.js has been installed correctly.

Step 3: Install Vue.js

In the Node.js environment, you can use the npm (Node.js Package Manager) command to install Vue.js. Run the following command in a terminal or command prompt to install Vue.js:

npm install vue

You can add the -g parameter to install Vue.js globally. Installing Vue.js globally allows you to use it in any project without having to install it in every project.

npm install -g vue

Wait a moment, the npm command will automatically download and install Vue.js. After the installation is complete, you can use the following command to check whether Vue.js is installed successfully:

vue -V

If the version number is returned, Vue.js has been successfully installed in the local environment.

Step 4: Use Vue.js

After the installation is complete, you can use the functions of Vue.js in the project. Typically, you can use Vue.js by introducing it in HTML.

Add the following statement in the HTML head:

<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>

If you want to use a CDN link to introduce Vue.js, you can use the following link:

<script src="https://unpkg.com/vue"></script>

After that, in your HTML You can use various functions of Vue.js in the code. Here is an example:

<div id="app">
  {{ message }}
</div>

<script>
  var app = new Vue({
    el: '#app',
    data: {
      message: 'Hello Vue!'
    }
  })
</script>

This will display the message "Hello Vue!" in a div.

In this example, the Vue instance is created and mounted into an HTML element. The Vue instance defines a data object, which contains a property named message. This attribute can be used in Vue templates, using {{ message }} for string interpolation to display the string Hello Vue!.
