在package.json中找到未使用的npm软件包 [英] Find unused npm packages in package.json

问题描述

有没有办法确定您的package.json文件中是否有不再需要的软件包?

Is there a way to determine if you have packages in your package.json file that are no longer needed?

例如，当试用一个程序包并稍后注释或删除代码但忘记卸载它时，我最终得到了几个可以删除的程序包.

For instance, when trying out a package and later commenting or deleting code, but forgetting to uninstall it, I end up with a couple packages that could be deleted.

确定软件包是否可以安全删除的有效方法是什么?

What would be an efficient way to determine if a package could safely be deleted?

推荐答案

您可以使用名为 depcheck的npm模块. (至少需要Node版本10).

You can use an npm module called depcheck (requires at least version 10 of Node).

1. 安装模块:

1. Install the module:

npm install depcheck -g

or

yarn global add depcheck

运行它并找到未使用的依赖项:

Run it and find the unused dependencies:

depcheck

这种方法的优点是您不必记住find或grep命令.

The good thing about this approach is that you don't have to remember the find or grep command.

要运行无需安装，请使用npx:

To run without installing use npx:

npx depcheck
