如何构建一个Vue插件并生成npm包

const antiReptilian = {
 install(Vue, options) {
  Vue.$antirept = checkText => {
   if (!checkText) return;
   let wrapperTemp = Vue.extend({
    // 1、创建构造器，定义模板
    template:
     '<div id="antiReptWrapper" style="z-index:9999 !important;"></div>'
   });
   let antiObj = new wrapperTemp().$mount().$el; // 2、创建实例
   antiObj.innerHTML = checkText;
   initScripts(antiObj);//3、解析并顺序执行js
   let App = document.getElementById('app');
   let wrapper = document.getElementById('antiReptWrapper');
   if (wrapper) {
    return;
   }
   App.appendChild(antiObj); // 4、把创建的实例添加到App中
   window.checkSucceed = res => {
    // 5、验证通过后移除实例
    App.removeChild(antiObj);
    window.location.reload();
   };
  };
 }
};

//重新引入js文件
const initScripts = function(cont) {
 let oldScripts = cont.getElementsByTagName('script');
 let newScripts = [];
 for (let i = 0; i < oldScripts.length; i++) {//提取内部js文件
  let newScript = document.createElement('script');
  newScript.type = 'text/javascript';
  newScript.innerHTML = oldScripts[i].innerHTML;
  if (oldScripts[i].src) {
   newScript.src = oldScripts[i].src;
  }
  newScripts.push(newScript);
 }
 while (oldScripts.length !== 0) {
  cont.removeChild(oldScripts[0]);//移除之前的js文件
 }
 for (let i = 0; i < newScripts.length; i++) {
  if (i == 0) {
   cont.appendChild(newScripts[i]);
  } else {//保证每个js文件按照之前的顺序执行
   newScripts[i - 1].onload = newScripts[
    i - 1
   ].onreadystatechange = function(event) {
    cont.appendChild(newScripts[i]);
   };
  }
 }
};
