解析 HTML-webpack-plugin 中样式表的路径

Question

我正在使用html-webpack-plugin 即时生成index.html。它工作得很好。但是，问题是，我还使用extract-text-webpack-plugin 从js 中提取css。

如html-webpack-plugin 的文档中所述

如果您在 webpack 的输出中有任何 CSS 资源（例如，使用 ExtractTextPlugin 提取的 CSS），那么这些资源将包含在 HTML 头部的标签中。

它添加了一个<link> 指向我的css。但是链接看起来像这样。

电流输出

<link rel="stylesheet" type="text/css" href="/js/../css/index.css" />

我需要这样解析网址

预期输出

<link rel="stylesheet" type="text/css" href="/css/index.css" />

我的 webpack 配置（仅限基本部分）

output: {
        path: path.resolve('./build/app/js'),
        filename: '[name].js',
        publicPath: '/js/',
    },
    plugins: [
      new ExtractTextPlugin(path.normalize('../css/index.css')),
      new HTMLwebpackPlugin({
        filename: '../index.html',
        template: './app/views/index.ejs',
        hash: true,
      }),
]

build 的文件夹结构是这样的

|--js
|  |-main.js
|
--css
|  |-index.css
|
|--fonts
|
|--img
|
index.html

插件的所有输出目的地都将与 webpack 的 output 配置中给出的 path 相关

Answer 1

当前输出 /js/../css/index.css 是由 publicPath /js/ 和提取 url ../css/index.css 引起的。

所以，如果你想解决它，只需这样做：

1. 将 publicPath 更改为 /。（我建议您将 publicPath 设置为您的应用开发根 url）。

2. 将new ExtractTextPlugin(path.normalize('../css/index.css')) 更改为new ExtractTextPlugin(path.normalize('css/index.css'))。

3. HTMLwebpackPlugin -> filename 也应该更改

Answer 2

这是一个完整的演示版！
