我正在处理一个大型Django项目，使用了jQuery、JavaScript、React和 SCSS。

我最初使用Webpack，但每次构建大约需要3 到5 分钟，由于我之前的配置，在开发模式下使用它并不现实。

我改用Rspack来节省时间，但构建仍然需要几分钟。 (由于与jQuery的一些问题，Vite不是一个选项)

我相信问题很可能出在我的配置上，但我不确定，或者这样的构建时间长是正常吗？

我的构建命令是：

cross-env NODE_ENV=production rspack build --config rspack.prod.config.js

解决方案

很可能是你在加载器的选择上出了问题。Rspack内置有快速加载器，比如swc，并且对CSS模块提供了一些选项，但你选择继续使用babel-loader和 postcss-loader等等。

无论如何，要想确诊，我推荐rsdoctor，但我猜通过切换到更快的内置加载器你会获得不少好处。

顺便提一下，config.cache = { type: "filesystem"} 是一个错误——filesystem不是有效的类型，合法的选项是 "persistent" 和 "memory"。文档：https://rspack.rs/config/cache
