javascript - 为什么 html-minifier 告诉我 : Unknown option `--minifyJS' ?

Question

问题:

我在全局安装了 uglify-js 并安装了 html-minifier。

HTML 的缩小工作正常，但是当我添加 --minifyJS 来缩小 javascript 时，它失败并出现以下错误:

  error: unknown option `--minifyJS'

我做错了什么？

代码:

html-minifier --input-dir ./viewsCopy --output-dir ./views-minified --collapse-whitespace --html5 --minifyJS

引用:

https://www.npmjs.com/package/html-minifier

查看文档后发现命令应该是 --minifyJS，但是，我快速查看了 --help 页面 html-minifier 表示如下；

--minify-js [value] Minify Javascript in script elements and on* attributes (uses uglify-js)

[value] 应设置为 true。

所以你的最终命令应该是

html-minifier --input-dir ./viewsCopy --output-dir ./views-minified --collapse-whitespace --html5 --minify-js true

如果是 HTML 文件的一部分，这似乎不会压缩 jQuery，因此将 javascript 放在外部文件中可能是有益的，或者替代的压缩器可能能够实现您想要的。
