PUG中的绝对路径 [英] Absolute path in PUG

问题描述

根据 PUG 文档( https://pugjs.org/language/includes.html ):

如果路径是绝对路径(例如，包含/root.pug)，则通过以下方式解析 在options.basedir之前.否则，路径将相对于 当前正在编译的文件.

If the path is absolute (e.g., include /root.pug), it is resolved by prepending options.basedir. Otherwise, paths are resolved relative to the current file being compiled.

我了解其中包括将路径介词作为选项传递给res.render(). 但是，我想避免尽可能多地重复自己的麻烦，并且希望使用顶级解决方案.

Which I understand consists of passing the path preposition as an option to res.render(). However, I want to avoid the trouble of repeating myself as much as I can and would prefer a top-level solution.

我尝试使用app.locals.basedir，但是我的代码无法使用basedir路径.因此，找不到该文件.

I tried using app.locals.basedir but my code fails to preprend the basedir path. The file therefore cannot be found.

这是我的 Express.js 应用程序索引的中坚力量:

Here is the backbone of my Express.js app index:

// index.js

const express = require('express');
const app = express();

const path = require('path');

app.locals.basedir = __dirname;

app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'pug');

app.get('/', function(req, res){
  res.render('index');
});

app.listen(3000, function(){
  console.log('Server started on port 3000');
});

我的 PUG 文件如下:

// views/index.pug

doctype html
html
  head
    script(type='text/javascript' src='/public/lib/map.js' defer='defer')

    title ExpressApp
  body
    h1 Hello, World!

我的项目结构:

project/
  index.js
  views/
    index.pug
  public/
    lib/
      map.js

在 PUG 文件中使用绝对路径插入javascript文件的正确方法是什么?

What is the correct way of inserting a javascript file using an absolute path in a PUG file?

推荐答案

在 Express.js 应用中，只需使用app.use(express.static('public'))设置Web根目录，以便应用程序知道在哪里提取静态文件. 不需要app.locals.basedir = __dirname.

In the Express.js app, the web root simply needs to be set using app.use(express.static('public')) so that the application knows where to fetch the static files. app.locals.basedir = __dirname is not needed.

因此在 PUG 文件中，应按以下方式插入脚本:

In the PUG file, the script should therefore be inserted as follows:

script(type='text/javascript' src='/lib/map.js' defer='defer')
