我覺得很難找出一種方法來優化我當前的堆棧。 我目前的油門加載時間（普通3g Chrome開發工具）是42-43秒。懶惰加載JS /優化加載時間
我試着懶加載CSS，但它似乎main.js文件（2.9MB）是最重的，我需要切斷它。 我該如何實現可以擴展的重組，而不僅僅是對於下面的代碼而言，對於所有的角度堆棧都是如此？
我希望我不必對它進行徹底改造。但只是建立在頂部優化它 我有代碼結構如下。

require('bootstrap');
// require('angular-mocks');
// require('../node_modules/bootstrap/dist/js/bootstrap.js');
