React Alloy ESLint & Prettier

使用 AlloyTeam 的 ESLint 配置

安装

npm install --save-dev eslint typescript @typescript-eslint/parser @typescript-eslint/eslint-plugin eslint-plugin-react eslint-config-alloy

在你的项目的根目录下创建一个 .eslintrc.js 文件,并将以下内容复制进去:

npm run eslint:fix
# 自动修复格式错误
npm run prettier:fix
# 检查当前是否覆盖了所有的规则

eslint-config-alloy 从 v3 开始,已经不包含所有样式相关的规则了,故不需要引入 eslint-config-prettier。只需要安装 prettier 及相关 VSCode 插件即可。

下面给出一个 AlloyTeam 使用的 .prettierrc.js 配置,仅供参考:

// .prettierrc.js
module.exports = {
    // 一行最多 100 字符
    printWidth: 100,
    // 使用 4 个空格缩进
    tabWidth: 4,
    // 不使用缩进符,而使用空格
    useTabs: false,
    // 行尾需要有分号
    semi: true,
    // 使用单引号
    singleQuote: true,
    // 对象的 key 仅在必要时用引号
    quoteProps: 'as-needed',
    // jsx 不使用单引号,而使用双引号
    jsxSingleQuote: false,
    // 末尾不需要逗号
    trailingComma: 'none',
    // 大括号内的首尾需要空格
    bracketSpacing: true,
    // jsx 标签的反尖括号需要换行
    jsxBracketSameLine: false,
    // 箭头函数,只有一个参数的时候,也需要括号
    arrowParens: 'always',
    // 每个文件格式化的范围是文件的全部内容
    rangeStart: 0,
    rangeEnd: Infinity,
    // 不需要写文件开头的 @prettier
    requirePragma: false,
    // 不需要自动在文件开头插入 @prettier
    insertPragma: false,
    // 使用默认的折行标准
    proseWrap: 'preserve',
    // 根据显示样式决定 html 要不要折行
    htmlWhitespaceSensitivity: 'css',
    // 换行符使用 lf
    endOfLine: 'lf'
};

prettier

yarn add prettier --dev

IDEA 配置

Go to Preferences | Tools | External Tools and click + to add a new tool. Let’s name it Prettier.

  • Program: $ProjectFileDir$/node_modules/.bin/prettier
  • Parameters: --write $FilePathRelativeToProjectRoot$
  • Working directory: $ProjectFileDir$

File watchs

To automatically format your files using prettier on save, you can use a File Watcher.

Go to Preferences | Tools | File Watchers and click + to add a new watcher.

Git整合

// 这一行就可以安装husky和lint-stage,并且配置好husky。
npx mrm lint-staged
