在package.json中使用shx删除和复制文件

package.json npm unix node.js

我有两个npm项目,一个是 Gatsby 项目名称 web-project 另一个是 Express 项目名称 server-project .

这是项目的文件结构:

- projects
   - web-project
      - public
      - package.json
   - server-project
      - package.json
      - public

如果我运行命令 npm run build 在里面 web-project/package.json ,我想为web项目生成构建文件,删除文件夹中的内容 server-project/public 并从以下位置复制内容 web-project/public 到 服务器项目/公共 .

我试着用 shx ,它安装在本地 网络项目 ,但它不起作用。Gatsby生成构建文件,但shx不会复制它们。

web项目/package.json

"scripts": {
    "build": "gatsby build && (shx find ../server-project/public -type f -delete && shx cp -R public/* ../server-project/public)"
    ...
  },

主要问题存在于这一部分:

shx find ../server-project/public -type f -delete

这个 -type f 中不支持标志 shx (参见 issue #177 ). 据推测 -delete 该标志也不受支持。

考虑用执行以下操作的node.js脚本替换该部分:

利用 shelljs find 方法。
使用以下命令迭代已找到的路径名数组 forEach() .
在身体的 forEach 回调检查它是否是一个文件并相应地删除。

例如,将其全部放入一个名为的npm脚本中 build :

"scripts": {
  ...
  "build": "gatsby build && node -e \"var sh = require('shelljs'), fs = require('fs'); sh.find('../server-project/public').forEach(function (file) { if (!fs.statSync(file).isDirectory()) { sh.rm(file); }});\" && shx cp -R \"public\" \"../server-project/public\""
  ...
}

笔记:

您尝试使用 find ../server-project/public -type f -delete 在您的OP中意味着您的意图是(仅)从中删除所有文件 ../server-project/public ( n 级别深)-但不要删除中的任何文件夹 ../服务器项目/公共 (再次 n 深层次)。这就是 node -e \"...\" 上述示例中的命令进行了复制。
nodejs命令行选项 -e 用于评估内联Javascript,本质上是这样的:
```
var sh = require('shelljs'),
    fs = require('fs');

sh.find('../server-project/public').forEach(function (file) {
    if (!fs.statSync(file).isDirectory()) {
        sh.rm(file);
    }
});
```
- 如您所见 Logical NOT ( ! ) 操作员 fs.statSync 方法和 isDirectory() 用于确定路径名是否是文件而不是目录/文件夹。
- 使用shelljs删除文件 rm 方法。
环球之星( * )在你的期末考试中 shx cp -R ... 命令和括号 (...) 省略了封装复合命令的部分。

您可以从以下位置删除通配符 shx cp -R public/* ../server-project/public ,因为递归标志将拾取源目录中的所有内容。这应该能让你得到你想要的东西-

shx cp -R public ../server-project/public

看起来你已经在使用了 find 在您的构建系统中。我利用tar,在我维护的一些构建系统中发现了很多,这对我来说很有效。tar很好地处理了各种各样的边缘情况,因为它最初是作为备份实用程序编写的。

在tar中,-是表示stdin或stdout的文件名,-T指定要备份的文件列表,-C指定其工作目录。这可以让你用管道把一堆东西粘在一起,完成一些非常酷的事情。例如,

(cd /path/to/src/files && find . -type f -name) \
| tar -T - -cf - \
| tar -C /path/to/dest -xvf -

子shell允许我在不影响其他命令的情况下查找目录
find在stdout上生成文件列表
第一个tar读取stdin上要存档的文件列表
第一个tar在stdout上生成存档
第二个tar将目录更改为/path/to/dest
然后提取stdin上的存档
'v'在执行此操作时打印其提取的文件列表

这将为您保留所有权、组成员资格、权限、符号链接、目录结构以及整个九码。即使是带有空格的文件名也不会把它弄乱。:)
