A detailed guide to using Vue-cli in Vue

Vue is a popular front-end framework favored by many developers for its flexibility and ease of use. In order to better develop Vue applications, the Vue team has developed a powerful tool-Vue-cli, which makes it easier to develop Vue applications. This article will introduce you to the use of Vue-cli in detail.

1. Install Vue-cli

Before using Vue-cli, you need to install it first. First, you need to make sure you have Node.js installed. Then, install Vue-cli using npm:

npm install -g vue-cli

Now, you have successfully installed Vue-cli!

2. Create a new project using Vue-cli

It is very easy to create a new project using Vue-cli. Just run the following command in the console:

vue init <template-name> <project-name>

Where template-name refers to the name of the Vue-cli template, and project-name refers to the name of the project you want to create.

For example, if you want to create a project named my-project based on the webpack template, you can use the following command:

vue init webpack my-project

Vue-cli will prompt you to enter some options, such as the project name, Author, project description, etc. Once completed, Vue-cli will create a new directory named my-project under the current directory.

3. Vue-cli template

Vue-cli has several built-in templates that can be used to create projects. If you want to use other templates, you can add them to your system during installation.

The following are the built-in templates of Vue-cli:

1. webpack: A complete project template based on webpack, including all webpack configurations.
2. webpack-simple: A simple project template based on webpack, suitable for rapid prototype development.
3. browserify: Project template based on browserify.
4. browserify-simple: A simple project template based on browserify, suitable for rapid prototype development.

In addition to the above built-in templates, there are also some templates maintained by the community, such as nuxt.

4. Vue-cli project structure

The project created by Vue-cli has a standard structure. The following is the structure of a Vue-cli project based on the webpack template:

├── build/                      // webpack配置文件
│   ├── webpack.base.conf.js
│   ├── webpack.dev.conf.js
│   └── webpack.prod.conf.js
├── config/
│   ├── dev.env.js
│   ├── index.js                // 用于根据环境加载不同的配置文件
│   ├── prod.env.js
├── node_modules/
├── src/                        // 项目源码
│   ├── assets/                 // 静态资源文件 (images, fonts)
│   ├── components/             // Vue组件
│   ├── App.vue                 // 根组件
│   └── main.js
├── static/                     // 静态文件 (favicon.ico)
├── test/                       // 测试文件
├── package.json
├── README.md

5. Vue-cli commands

1. npm run dev

Run the development server. This will start a development server on localhost:8080 and automatically reload the application when you make changes.

npm run dev

2. npm run build

Build the application. This will package and optimize the code for production, reduce file size, and generate static files so you can upload them to your web server.

npm run build

3. npm run unit

Run unit tests. This will run the configured unit tests and output the test results.

npm run unit

4. npm run e2e

Run end-to-end tests. This will run the configured end-to-end tests and output the test results.

npm run e2e

5. npm run lint

Run the ESLint static code checker. This will scan your code and output any errors and warnings.

npm run lint
