使用babel與@babel/node

安裝

yarn add -D @babel/cli @babel/node

編譯entry-server.js

yarn babel ./src/ssr/entry-server.js  --presets=@babel/preset-env

var hello = () => {
  return "Hello World";
};

console.log(hello());

結果

"use strict";

require("core-js/modules/es6.array.iterator");

require("core-js/modules/es6.promise");

require("core-js/modules/es7.promise.finally");

var hello = function hello() {
  return "Hello World";
};

console.log(hello());

Done in 2.28s.
