main 程序入口文件，默認爲根目錄index.js，當require('moduleName')調用時，就會加載main字段指定的目錄下的文件module 使用ES6的module模塊引入該模塊時加載的文件路徑，即使用import 'xx' from './xx'所指定的路徑
main和module的區別：vue.runtime.common.js 通過 module.exports = Vue導出VUE,commonjs規範vue.runtime.esm.js 通過 export default Vue導出VUE，ES6規範
unpkg cdn公共庫,https://unpkg.com/[email protected]/jsdelivr cdn公共庫，https://cdn.jsdelivr.net/npm/vue/typings TypeScript 的入口文件。files 發佈的文件集合，如vue發佈後的在node_modules下內容sideEffects 聲明該模塊是否包含 sideEffects（副作用），從而可以爲 tree-shaking 提供更大的優化空間。gitHook git鉤子，用於git提交檢查lint-staged 代碼檢查。所有的js在執行git add前先執行eslint --fix檢查commitizen 規範git commit的信息
