vscode和eslint的配置極其繁瑣，為了不勞民傷財是目，本著救天下程序員于水深火熱之中的宏愿谤饭，地獄不空，誓不成佛懊纳，特施恩于爾等揉抵。（怎么就沒表情符號可用呢，這讓我如何嘚瑟嗤疯？看來只能說：你來打我撒Ｔ┙瘛）
eslint與vscode相輔相成，再也不怕代碼不規(guī)范了茂缚，任你怎么亂寫戏罢，保存代碼后可手動或是自動格式化代碼！
一阱佛、需要用到的vscode插件：
1帖汞、ESLint，Vetur（必須）
2凑术、以下插件就是自己的喜好羅翩蘸，有助于美化樣式和輔助提示（用了才知道，那個不痛淮逊，月月輕松４呤住）。
Auto Close Tag（自動標(biāo)簽閉合）泄鹏，
Auto Rename Tag（標(biāo)簽重命名）郎任，
Bracket Pair Colorizer 2（成對括號顏色標(biāo)記），
GitLens--Git supercharged（git代碼提交歷史信息）备籽，
Highlight Matching Tag（高亮匹配的成對標(biāo)簽）舶治，
HTML CSS Support（樣式屬性提示）
HTML Snippets（html標(biāo)簽提示）
Prettier - Code formatter（代碼美化工具分井，下載了vuter，就沒必要下載它了）
Path Intellisense（路徑補全提示）
vscode-icons（文件圖標(biāo)樣式）
二霉猛、好了尺锚，你也是夠了，上代碼惜浅！配置詳情如下瘫辩。
vscode > settings.json（文件 > 首選項 > 設(shè)置 > 在settings.json中編輯；編輯器左下方設(shè)置圖標(biāo)也可進入配置坛悉。）

三伐厌、ESLint配置如下（配置項及其之多，要想明白每一項的配置裸影，花點時間可是不少罢豕臁）
- .eslintrc.js，項目根目錄下新建此文件轩猩。
- 下載所需的npm包：eslint刃唐，eslint-friendly-formatter，eslint-loader界轩，eslint-plugin-html画饥，eslint-plugin-vue
- 說明：extends: ['eslint:recommended', 'plugin:vue/essential'],eslint:recommended表示eslint的默認(rèn)生效的規(guī)則，下面rules的規(guī)則大多不在默認(rèn)項中浊猾，或是對規(guī)則有自己的配置抖甘，畢竟是和vscode配合使用，最終要在保存的時候一鍵格式化的葫慎，有些eslint默認(rèn)配置與vuter格式化工具規(guī)定的不一樣衔彻，所以需要修改eslint的配置。
