刚充好 USDT ，7 块的就没了。。。

搞笑又扎心

@uni #9 为什么不去了解一下背景呢？大 npm 包被影视站利用，成本你出么？

如果你嫌弃就不要用，没有收费为何要承担被你喷的困境。

是的你没有了解背景的义务，但同时你也没有喷的权利。

npmmirror v.s tencent mirror ，坐标湖北武汉, 结果：

这个包水平低下，严重浪费开发者磁盘，建议停用

这是个公益站，恶心不用就是。没有收你一分钱哦~
因为我觉得很好，必须站出来说句好
因为 npmmirror 我的常用命令 `corepack use pnpm@latest && ncu-safe && pi && p dedupe && p prune` 快了不少

export COREPACK_NPM_REGISTRY=https://registry.npmmirror.com


```sh
where ncu-safe
ncu-safe: aliased to ncu -t minor -u

where pi
pi: aliased to pnpm install

where p
p: aliased to pnpm
```

确实烦，但是一个包 325MB 就不得不反思为什么 npm 包要这么大？
npm 应该用来分发代码, assets 请自建分发，参考 puppeteer 下载浏览器实例.
