1.使用

npm install -g @vue/cli
# or
yarn global add @vue/cli

查看版本(是否安装成功):vue -V(大写的V)

2.命令变化

  Commands:

    create [options] <app-name>      create a new project powered by vue-cli-service // 创建一个由vue-cli-service支持的新项目
    add <plugin> [pluginOptions]     install a plugin and invoke its generator in an already created project // 在已创建的项目中添加插件
    invoke <plugin> [pluginOptions]  invoke the generator of a plugin in an already created project // 在开发者模式下以零配置运行一个js或vue文件
    inspect [options] [paths...]     inspect the webpack config in a project with vue-cli-service // 在vue-cli-service的项目中检查webpack配置
    serve [options] [entry]          serve a .js or .vue file in development mode with zero config // 简单理解为开发环境下启动命令
    build [options] [entry]          build a .js or .vue file in production mode with zero config // 在生产模式下以零配置构建一个js或vue文件
    init <template> <app-name>       generate a project from a remote template (legacy API, requires @vue/cli-init) // 旧api 需要@vue/cli-init // 就是原来的vue-cli init <template> <app-name>

3.创建一个项目
新建文件夹,在该文件夹下打开命令窗口,输入以下命令,
vue create project-name
这时你会看见

Vue CLI v3.0.0-beta.6
? Please pick a preset: (Use arrow keys)
> xs-default (vue-router, vuex, stylus, babel, pwa, eslint, unit-jest) // 这是我运行过之后的默认设置,第一次执行create是没有的
  default (babel, eslint)
  Manually select features

按键盘上下键选择默认(default)还是手动(Manually),如果选择default,一路回车执行下去就行了(注:现在vue-cli3.0默认使用yarn下载),这里我选择手动,

10.键入N不记录,如果键入Y需要输入保存名字,如第一步所看到的我保存的名字为xs-default

Vue CLI v3.0.0-beta.6
? Please pick a preset: Manually select features
? Check the features needed for your project: Router, Vuex, CSS Pre-processors, Linter, Unit
? Pick a CSS pre-processor (PostCSS, Autoprefixer and CSS Modules are supported by default): Stylus

? Pick additional lint features: Lint on save
? Pick a unit testing solution: Jest
? Where do you prefer placing config for Babel, PostCSS, ESLint, etc.? In dedicated config files
? Save this as a preset for future projects? (Y/n) // 是否记录一下以便下次继续使用这套配置

11.确定后,等待下载依赖模块

12.装好后,启动

cd vue-pro3.0-demo // 进入项目根目录
yarn serve // 启动项目

5.png

13.项目目录,现在的目录是3.0的cli看上去简洁多了,去掉了2.0 build和config等目录

14.修改端口,在根目录下创建vue.config.js

ARAM73G_ZUA)9$HYSZJRFQG.png


vue.config.js相关配置请参考 https://github.com/vuejs/vue-cli/blob/dev/docs/config.md
在vue.config.js找到

 

devServer: {
        open: process.platform === 'darwin',
        host: '0.0.0.0',
        port: 1234,
        https: false,
        hotOnly: false,
        // See https://github.com/vuejs/vue-cli/blob/dev/docs/cli-service.md#configuring-proxy
        proxy: null, // string | Object
        before: app => {}
    },

打包上线

在开发完项目之后,就应该打包上线了。 vue-cli 也提供了打包的命令,在项目根目录下执行:

npm run build

执行完之后,可以看到在项目根目录下多出了一个 dist 目录,该目录下就是打包好的所有静态资源,直接部署到静态资源服务器就好了。

实际上,在部署的时候要注意,假设静态服务器的域名是 http://static.baidu.com ,那么对应到访问 <项目根目录>/dist/index.html 的 URL 一定要是 http://static.baidu.com/index.html ,其他的静态资源以此类推。

单元测试

执行:

npm run test

 项目配置 Vue.config.js

我们发现之前的build和config文件夹不见了,那么应该如何配置 如webpack等的配???

  

不用担心,只需要在项目的根目录下新建 vue.config.js 文件(是根目录,不是src目录)

module.exports = {
 // 基本路径
 baseUrl: '/',
 // 输出文件目录
 outputDir: 'dist',
 // eslint-loader 是否在保存的时候检查
 lintOnSave: true,
 // use the full build with in-browser compiler?
 // https://vuejs.org/v2/guide/installation.html#Runtime-Compiler-vs-Runtime-only
 compiler: false,
 // webpack配置
 // see https://github.com/vuejs/vue-cli/blob/dev/docs/webpack.md
 chainWebpack: () => {},
 configureWebpack: () => {},
 // vue-loader 配置项
 // https://vue-loader.vuejs.org/en/options.html
 vueLoader: {},
 // 生产环境是否生成 sourceMap 文件
 productionSourceMap: true,
 // css相关配置
 css: {
  // 是否使用css分离插件 ExtractTextPlugin
  extract: true,
  // 开启 CSS source maps?
  sourceMap: false,
  // css预设器配置项
  loaderOptions: {},
  // 启用 CSS modules for all css / pre-processor files.
  modules: false
 },
 // use thread-loader for babel & TS in production build
 // enabled by default if the machine has more than 1 cores
 parallel: require('os').cpus().length > 1,
 // 是否启用dll
 // See https://github.com/vuejs/vue-cli/blob/dev/docs/cli-service.md#dll-mode
 dll: false,
 // PWA 插件相关配置
 // see https://github.com/vuejs/vue-cli/tree/dev/packages/%40vue/cli-plugin-pwa
 pwa: {},
 // webpack-dev-server 相关配置
 devServer: {
  open: process.platform === 'darwin',
  host: '0.0.0.0',
  port: 8080,
  https: false,
  hotOnly: false,
  proxy: null, // 设置代理
  before: app => {}
 },
 // 第三方插件配置
 pluginOptions: {
  // ...
 }
}
举个栗子

    

上图内容做了两块内容,经测试没有问题

   1.将启动端口设置为 8080

   2.设置路径别名
