Typescript 为什么ts加载器不编译我的类型脚本？

我试图使用Webpack使用ts加载程序编译一些类型脚本，但它并没有像我预期的那样运行tsc。如果我对ts文件进行更改，webpack不会将其编译回js，如果我完全删除生成的js文件并重新运行webpack，也会发生同样的情况

Typescript设置得很好，因为我可以运行

/node\u modules/Typescript/bin/tsc

，它可以很好地生成js文件。我认为ts loader应该对我的tsconfig.json运行tsc，对吗？如果是这样的话，为什么它不按预期接收更改并生成我的js

正如您所看到的，我的入口点是

/Client/boot Client.ts

，甚至在运行Web包时也不会编译它

我正在运行的特定webpack命令是：

/node\u modules/webpack/bin/webpack.js——进度

这将提供以下输出

webpack.config.js

ts loader

不会将任何文件写入磁盘。它编译您的TypeScript文件并将生成的JavaScript传递给webpack，这在内存中发生。没有理由输出已编译的JavaScript，因为它包含在包中。该包包含您需要的所有内容

您可以看到，

/Client/boot Client.ts

是通过以下行编译的（它并不意味着写入磁盘）：

[335] ./Client/boot-client.ts 951 bytes {0} [built]

啊，好吧，这很有道理。因此，是否建议跳过手动typescript编译，而让webpack通过ts加载器完成它的工作？我的src中应该只有ts文件，不应该也需要相应的js文件吗？是的，如果你使用的是webpack，你不需要担心有js文件。你是想使用webpack还是手动编译它们，这取决于你是否想捆绑应用程序（基本上与JS使用webpack的原因相同）。好的，我现在看到了webpack的好处。谢谢你的帮助。
