本文介绍如何在npm脚本中使用package.json文件中的信息，如名称和版本号等，来自动化创建文件夹及文件名。通过具体示例展示了如何在构建过程中利用这些变量。

In this lesson we will show that you can leverage values that you already have provided in your package.json file such as the name and version keys. You may want to use these in your npm scripts as you create folders and file names.

To check all the npm veriable:

npm run env | grep "npm_package_" | less

So for example we want is when we do "build" it will create a folder named as npm_package_version's number.

    "build": "npm-run-all build:*",
    "prebuild": "rm -rf public/$npm_package_version",
    "build:html": "pug --obj data.json src/index.pug --out public/$npm_package_version/",
    "build:css": "node-sass src/index.scss | postcss -c .postcssrc.json | cssmin > public/$npm_package_version/index.css",
    "build:js": "mustache data.json src/index.mustache.js | uglifyjs > public/$npm_package_version/index.js"
