建立一个电子项目需要多长时间？

Question

我有一个小项目，几乎没有 npm 依赖项，构建它需要 30 多分钟（并且还在继续）。不知道是正常还是有什么问题导致构建延迟。

我有两个问题：

1. 花这么长时间正常吗？
2. 构建一个项目平均需要多长时间？

我的 package.json：

Answer 1

1. 这取决于很多因素，包括您的硬件和项目规模。但总的来说，对于中等规模的项目，应该花费那么长时间。

2. 通常会在几分钟内完成，比如在不错的硬件上需要 3-4 分钟。

一些观察：

1. 根据您的依赖关系树，您似乎没有任何重 依赖关系。所以假设你的硬件不错，应该不会花那么长时间。

2. 另外，您似乎正在使用 webpack，请确保您已正确设置项目目录，并且它不包括您的 node_modules 文件夹。因为如果是这样，由于 webpack 捆绑了整个 node_modules 目录而不是通常的 src 目录，可以解释大的构建时间。

3. 如果是 typescript 项目，请确保在您的 tsconfig.json 文件中为您在外部使用的所有（如果有）预编译库添加 exclude 键你的node modules 目录。我个人以前也遇到过这种情况，它确实会显着增加您的构建时间。
