umi增加lint校验，fix代码

umi生成项目时自带添加了lint相关npm包

1.增加script中指令

"lint": "umi g tmp && npm run lint:js && npm run lint:style && npm run lint:prettier",
    "lint-staged:js": "eslint --ext .js,.jsx,.ts,.tsx ",
    "lint:fix": "eslint --fix --cache --ext .js,.jsx,.ts,.tsx --format=pretty ./src && npm run lint:style",
    "lint:js": "eslint --cache --ext .js,.jsx,.ts,.tsx --format=pretty ./src",
    "lint:prettier": "prettier --check \"src/**/*\" --end-of-line auto",
    "lint:style": "stylelint --fix \"src/**/*.less\" --syntax less",
    "prettier": "prettier -c --write \"src/**/*\"",
    "precommit": "lint-staged",
    "precommit:fix": "npm run lint:fix && npm run prettier && npm run lint:prettier && npm run lint:style"

2.lint-staged部分：

 "**/*.less": "stylelint --syntax less",
    "**/*.{js,jsx,ts,tsx}": "npm run lint-staged:js",
    "*.{ts,tsx}": "npm run lint-staged:js",
    "*.{js,jsx}": "npm run lint-staged:js"

3.新建package.json同级目录文件 .stylelintrc.js

const fabric = require('@umijs/fabric');

module.exports = {
  ...fabric.stylelint,
};

npm run /yarn precommit:fix
