进出口使用此设置为我的项目的基础:https://www.typescriptlang.org/docs/handbook/react-&-webpack.html“的WebPack” VS“的WebPack --watch”创建不同的输出
当我运行webpack
,它编译,在浏览器中工作的包。
当我运行webpack --watch
,它重新编译的文件的变化,而导致这个错误在浏览器:
Uncaught ReferenceError: exports is not defined
我看了一下两者的输出,它看起来像webpack --watch
不包括webpack引导程序代码或我的模块 - 只有输入文件transpiled。
webpack
- 包括我所有的模块在一个文件中,使用webpacks自己的模块需要一起。
- E.g:
var io = __webpack_require__(20);
webpack --watch
- 只有包括我的输入模块 - 没有其他的模块,没有
__webpack_require__
。 - E.g.
var io = require("socket.io-client");
