你是把Babel和Webpack放在devDependencies还是Dependencies ?

Do you put Babel and Webpack in devDependencies or Dependencies?

本文关键字：devDependencies 还是 Dependencies 放在 Webpack Babel      更新时间：2023-09-26

我是npm的新手，不太明白dependencies和devDependencies应该包含什么。我知道对于测试库，它们应该进入开发阶段，但是对于babel和webpack之类的东西呢?它们是否也应该在开发中，因为它们只用于将es6和JSX编译成普通的JS?我的理解是，当您部署到heroku时，它已经与必要的库进行了转换，因此没有必要在生产环境中托管它们。

babel和webpack包将进入devDependencies部分，因为这些包是在编译和捆绑代码到bundle.js &等文件(s) .

在生产环境中，您将运行您的代码的bundle.js构建/生成的代码将不再需要这些依赖项。

不管基本上每个人都说什么，我要提供一点理智…这真的很简单:

你的项目会被另一个项目npm install编辑吗?也就是说，你正在编写一个NPM模块吗?它最终会在其他项目package.json中结束吗?

没有?

然后将所有内容放入dependencies。

是吗?

  • dependencies:您希望项目下游消费者和项目开发人员安装的内容:
  • peerDependencies:你的下游用户需要确保他们已经安装了
  • bundleDependencies:下游用户将需要的东西，并且不需要单独安装，因为当你npm publish时，这些将与你的包"捆绑"在一起。
  • optionalDependencies:东西很好，但没有将不会导致致命错误
  • devDependencies:只在你的项目中使用的东西。

它的简短之处在于:模块不会神奇地以不同的方式安装。

Dev dependency是仅用于开发服务器的，这些是devdependency:所有未在源代码中使用或导入的包都是devDependencies
