构建

1. 添加eslint & typescript

npm install -D eslint typescript 
Tips: 推荐使用eslint 7版本, 8版本与webstorm有兼容性问题 

2. 添加解析器 & 规则

解析器
npm install -D @typescript-eslint/parser 
规则插件
npm install -D @typescript-eslint/eslint-plugin

demo:
{
  "parser": "@typescript-eslint/parser",
  "plugins": ["@typescript-eslint"],
  "extends": ["plugin:@typescript-eslint/recommended"] // 使用推荐的规则
  "rules": {
    "@typescript-eslint/rule-name": "error" // 自定义的typescript规则
  }
}
 

3. 添加husky & lint-staged

npm install -D husky@4.3.5
npm install -D lint-staged

demo: 
"lint-staged": {
    "src/**/*.{ts,tsx}": [
      "prettier --write",
      "eslint",
      "git add"
    ],
    "src/**/*.{scss,css}": [
      "prettier --write",
      "git add"
    ]
  },
  "husky": {
    "hooks": {
      "pre-commit": "lint-staged"
    }
  }

4. 添加prettier 以及 prettier

npm install -D prettier 
npm install -D eslint-plugin-prettier eslint-config-prettier

然后只需要在extends添加即可，这样，eslint & prettier的规则就可以同时使用了

{
  "extends": ["plugin:prettier/recommended"]
}

5. 添加eslint-plugin-react (对tsx的支持)

npm install -D eslint-plugin-react

"extends": [
    "plugin:react/recommended"
  ]

6. 配置打包webpack

webpack保持在5的最新版本进行开发

"webpack": "^5.67.0",
"webpack-cli": "^4.9.2",
"webpack-dev-server": "^4.7.3",
"webpack-merge": "^5.8.0"

"url-loader": "^4.1.1",
"file-loader": "^6.2.0",
"css-loader": "^6.5.1",
"ts-loader": "^9.2.6",
"style-loader": "^3.3.1",
"sass-loader": "^10.1.1",
"react-hot-loader": "^4.8.0",

"mini-css-extract-plugin": "^2.5.2",
"html-webpack-plugin": "^5.5.0",

最后别忘了安装一些可供调用的类 & Interface

"@types/jest": "^27.4.0",
"@types/koa": "^2.13.4",
"@types/koa-router": "^7.4.4",
"@types/node": "^16.11.20",
"@types/react": "^17.0.38",
"@types/react-dom": "^17.0.11",

推荐的Node版本是v14.18.3 npm v6.14.15
