使用Node.JS Jade / Pug进行编程HTML评论

Question

对于layout.jade，使用环境变量＆＃34;变量=开发＆＃34;，

我想要

  body
    // Environment: process.env.Environment || "'Environment' App Setting not found"

生成为 <!-- Environment: Development -->

到目前为止，它正在生成Environment: process.env.Environment || "'Environment' App Setting not found"

我该怎么做？

Answer 1

借鉴this response：

body
    != "<!-- Environment: " + (process.env.Environment || "'Environment' App Setting not found") + " -->

为了便于阅读，您还可以将注释与您在上一行中设置的变量连接起来。

body
    - var envComment = process.env.Environment || "'Environment' App Setting not found"
    != "<!-- Environment: " + envComment + " -->"

但是，我认为Pug通常无法访问process.env。您需要将Node.js / Express中的变量作为变量传递给它。有关传递process.env.Environment变量的信息，请参阅this page的底部。
