图文并茂手把手教你How to copy files or directory in nodejs npm scripts编写脚本用npm或者node命令复制文件

每天都要开心哦~~~

今天来个双语文档

• 先放出来官方文档
  
  https://www.npmjs.com/package/copyfiles

先来说一下npm 执行的方式

1.首先，进入项目目录，下载依赖，添加到dev依赖

1.First, Go to your application project, Install copyfiles dependency with the below command Note: please add this as devDependencies using –save-dev

npm install --save-dev copyfiles

2.把下面代码放到你的package.json,就像下图那个样子

2.In the package.json file, There is a script tag, add below line of code

"scripts": {
    "copy": "copyfiles source destination"
}

3.最后，我们可以用npm run copy命令进行拷贝文件操作啦~~

3.Finally, You can script by calling npm run copy command in terminal

4.npm copyfiles examples

4.自定义拷贝案例

• 来看一些案例吧~discuss some examples
• 拷贝文件到某个目录Copy specific files into directory
• 假如你的js文件放在src/assets，你怎么只拷贝里面的JS文件到另一个目录呢？
• Suppose you have a javascript file in src/assets folder. How do you copy only javascript files to the output directory

"copyjavascript": "copyfiles src/assets/*.js destination"

• 尝试一下下面的命令，感受一下吧~~

npx copyfiles dist test
npx copyfiles dist/spa/assets/*.js out
npx copyfiles dist/spa/* out
npx copyfiles dist/spa/* test
npx copyfiles dist/spa test
npx copyfiles dist/spa test -a
npx copyfiles -a dist/spa test
npx copyfiles -a dist/spa/assets/* test

接下来说一下我们使用node命令执行脚本命令的方式

• 创建scripts\copy.js
• 编写代码

const copyfiles = require('copyfiles');

const copyEnd = () => {
  console.log('我拷贝完啦~~~');
};
// 这个命令是针对根目录的哦
copyfiles(['dist/spa/assets/*.js', 'out'], { all: true }, copyEnd);

• 运行代码

node scripts/copy.js

• 今天就写到这里啦~小伙伴们，(￣ω￣(￣ω￣〃 (￣ω￣〃)ゝ我们明天再见啦~~
• 大家要天天(^▽)哦
