一、创建项目
1、语法格式
<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n3" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">vue create <项目名></pre>
注意: 项目名 不支持驼峰（含大写字母）
建议使用 使用全部小写字母跟字母之间使用短横线
2、栗子
<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n7" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">vue create vue-example</pre>
二、选项信息
1、预设配置
如果之前有创建过项目并保存了配置 会提示多出一个预设的配置选项
2、默认设置
default（babel，eslint）
默认设置（直接enter）非常适合快速创建一个新项目的原型，没有带任何辅助功能的 npm包
3、自定义配置
Manually select features
提供可选的包的信息
三、自定义配置
1、说明
命令行创建项目需要用:
方向键选择相关选项,回车进入下一级
空格键 选择/取消选择
A键全选/取消全选
2、选项概要
<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n30" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">>( ) Babel //转码器，可以将ES6代码转为ES5代码，从而在现有环境执行。
( ) TypeScript// TypeScript是一个JavaScript包含并扩展了JavaScript的语法，需要被编译输出为 JavaScript在浏览器运行
( ) Progressive Web App (PWA) Support// 渐进式Web应用程序
( ) Router // vue-router（vue路由）
( ) Vuex // vuex（vue的状态管理模式）
( ) CSS Pre-processors // CSS 预处理器（如：less、sass）
( ) Linter / Formatter // 代码风格检查和格式化（如：ESlint）
( ) Unit Testing // 单元测试（unit tests）
( ) E2E Testing //（end to end） 测试</pre>
3、Babel
转化器, 可以将ES6代码转为ES5代码
4、Router
是否使用history router
-
hash
默认值,浏览器url址栏中带#符号
-
history
单页客户端应用(比如移动端应用)
5、Vuex
vue的状态管理
6、Progressive Web App (PWA) Support
PWA全称Progressive Web App，直译是渐进式WEB应用
7、预处理器
主要为css解决浏览器兼容、简化CSS代码等问题（Sass诞生于2007年，最早也是最成熟的一款CSS预处理器语言）
选择一个你熟悉的预编译语言(LESS)
<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="csharp" cid="n49" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">? 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):
//Sass安装需要Ruby环境，是在服务端处理的，SCSS 是 Sass3新语法（完全兼容 CSS3且继承Sass功能）
SCSS/SASS
//Less最终会通过编译处理输出css到浏览器，Less 既可以在客户端上运行，也可在服务端运行 (借助 Node.js)
LESS
//Stylus主要用来给Node项目进行CSS预处理支持，Stylus功能上更为强壮，和js联系更加紧密，可创建健壮的、动态的的CSS。
Stylus</pre>
8、ESLint
提供一个插件化的javascript代码检测工具(新手不建议开启)
<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="dart" cid="n52" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">? Pick a linter / formatter config: (Use arrow keys)
ESLint with error prevention only
ESLint + Airbnb config
ESLint + Standard config
ESLint + Prettier</pre>
9、检测时机
<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="csharp" cid="n54" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">? Pick additional lint features: (Press <space> to select, <a> to toggle all, <i> to invert selection)
// 保存就检测
( ) Lint on save
// fix和commit时候检查
( ) Lint and fix on commit </pre>
9、单元测试
<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="cpp" cid="n56" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">? Pick a unit testing solution: (Use arrow keys)
//mocha灵活,只提供简单的测试结构，如果需要其他功能需要添加其他库/插件完成。必须在全局环境中安装
Mocha + Chai
//安装配置简单，容易上手。内置Istanbul，可以查看到测试覆盖率，相较于Mocha:配置简洁、测试代码简洁、易于和babel集成、内置丰富的expect
Jest</pre>
10、存放配置的路径
<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="java" cid="n58" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: normal; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">? Where do you prefer placing config for Babel, PostCSS, ESLint, etc.? (Use arrow keys)
// 独立文件放置
In dedicated config files
// 放package.json里
In package.json</pre>
11、是否保存本次配置
<pre spellcheck="false" class="md-fences mock-cm md-end-block" lang="kotlin" cid="n60" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace; margin-top: 0px; margin-bottom: 20px; font-size: 0.9rem; display: block; break-inside: avoid; text-align: left; white-space: pre-wrap; background: rgb(51, 51, 51); position: relative !important; padding: 10px 10px 10px 30px; width: inherit; color: rgb(184, 191, 198); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">// y:记录本次配置，然后需要你起个名; n：不记录本次配置
? Save this as a preset for future projects? (Y/n) </pre>
