Running in the browser environment

I'm looking for a module to format HTML in interactive examples on the React docs website. I was hoping to use `diffable-html` but it looks like it runs only in Node. Would it be feasible to remove the dependency on Node APIs? If not, do you know of any other module that can take an HTML string without any whitespace or line-breaks and format it for people to inspect?

Issue 中没有指定源文件或测试。首先检查 diffable-html 使用了哪些 Node APIs，以及其 formatter 是否可以在浏览器中运行；当该 package 能够在 React 文档环境中格式化紧凑 HTML，或该 issue 指出了合适的浏览器兼容替代方案时，即可视为完成。
