How to install nodejs scaffolding vuecli

Node.js is a lightweight JavaScript runtime environment that can run JavaScript on the server side, allowing developers to utilize the programming capabilities of JavaScript for server-side programming. Vue.js is a popular front-end framework that is easy to use, efficient and flexible. It is widely used in mobile and PC web development.

In order to use Vue.js for web development more conveniently, Vue.js provides a scaffolding tool, namely Vue CLI (Vue Command Line Interface). Vue CLI provides a standardized tool chain that includes building, launching, and packaging functions to help developers quickly build Vue.js applications.

This article will introduce how to install Node.js and Vue CLI, and create a basic Vue.js application.

Install Node.js

To use Vue CLI, you first need to install Node.js. Node.js can be downloaded from the official website https://nodejs.org/.

Choose the corresponding version to download according to your own system. After the installation is completed, open the command line window (Windows users) and enter the following command to check whether Node.js is installed successfully:

node -v

If returned If you see the version number of Node.js, it means that Node.js is installed successfully.

Install Vue CLI

Vue CLI can be installed through npm. npm is the package manager for Node.js, which can download and install various JavaScript packages and tools from the public npm repository.

Enter the following command in the command line window to install Vue CLI:

npm install -g @vue/cli

This command will install Vue CLI into the global environment and can be used anywhere.

Creating a Vue.js application

After installing the Vue CLI, you can use it to create a Vue.js application.

Enter the following command in the command line window to create a basic Vue.js application:

vue create my-project

Among them, my-project is the project name, which can be modified according to your own needs.

After executing this command, Vue CLI will prompt you to select a preset, which provides some different options, including:

• Default (Babel, CSS)
• Default (Babel, PostCSS, ESLint)
• Default (TypeScript)
• Default (TypeScript, ESLint)
• Manually select features

These presets will automatically configure some commonly used options, such as using Babel, PostCSS, ESLint, etc. If you only need a basic application, you can choose the default option.

The Vue CLI will then download all required packages and dependencies and generate a basic Vue.js application.

Run the Vue.js application

After you create the Vue.js application, you can run it. Enter the project directory in the command line window and enter the following command:

cd my-project
npm run serve

This will start a local development server, which can be viewed in the browser at http://localhost:8080 to view the application.

Summary

Node.js and Vue CLI are both very powerful tools that can help developers quickly build Vue.js applications. This article shows you how to install Node.js and the Vue CLI, and create a basic Vue.js application. I hope this article can help you use Vue.js for web development more conveniently.
