一、安裝 Eslint

首選得在ide安裝eslint插件

二、安裝 Prettier-Code formatter

目前新的vscode 都需要安裝這個(gè) 代碼格式化插件

否則會提示 Extension 'esbenp.prettier-vscode' is configured as formatter but not available. Select a different default formatter to continue.

三、安裝Vetur
目前vue 用的比較多，當(dāng)然避不了的使用一個(gè)格式.vue的文件，如：

四、配置 setting.json

找到File > Preference > Settings > Text Editor > Code Actions On Save > Edit in setting.json打開進(jìn)行編輯
截圖如

添加如下的配置到你的setting.json (這個(gè)注釋很全就不過得解釋了)

{
    "workbench.startupEditor": "newUntitledFile",

    },

    "editor.codeActionsOnSave": {
      "source.fixAll.eslint": true
    },
  }

五、配置 .eslintrc.js

現(xiàn)在需要將項(xiàng)目中對應(yīng)的elsintrc.js配置一下，來規(guī)范整個(gè)項(xiàng)目的代碼風(fēng)格，避免團(tuán)隊(duì)人員多了，代碼五花八門,

個(gè)人配置大概如下：

module.exports = {
  root: true,
  parserOptions: {
    parser: 'babel-eslint',
    sourceType: 'module'
  },

  },

    'array-bracket-spacing': [2, 'never']
  }
}
 

六、配置 .editorconfig

再配置一個(gè)代碼 空格，縮進(jìn)、換行等規(guī)范

看看官方對這個(gè)editor的介紹

# https://editorconfig.org
root = true
 
[*]
charset = utf-8
indent_style = space
indent_size = 2
end_of_line = lf
insert_final_newline = true
trim_trailing_whitespace = true
 
[*.md]
insert_final_newline = false
trim_trailing_whitespace = false
