这可能很长,但请多多包涵:
问题在于 nunjucks-loader 将其作为 JavaScript 文件 (According to the first paragraph) 传递。
改为使用nunjucks-html-loader。
使用 npm 或 yarn 安装它:
首先,我们安装 nunjucks-html-loader:
npm i nunjucks-html-loader -D
或
yarn add nunjucks-html-loader -D
我还建议安装(这是可选的)webpack-glob-folder-entries(更多信息)
npm i webpack-glob-folder-entries -D
或
yarn add webpack-glob-folder-entries -D
那么,如果我们认为我们有以下文件夹结构:
- client/
-templates/
-index.njk
-layout.njk
-_partials/
- webpack.config.js
在 index.njk 中我们有这样的东西:
<!-- index.nunjucks -->
{% extends "layout.njk" %}
{% block content %}
<h1> Here comes my content that is injected to layout.njk!</h1>
{% endblock %}
我们可以只配置 webpack,设置如下:
//#1: Define the HTML Webpack Plugin:
const HtmlWebpackPluginConfig = new HtmlWebpackPlugin({
filename: 'index.html',
inject: 'body',
// Here is part of the magic, we get the index.njk but we tell
// webpack to pass it through the nunjucks-html-loader
template: 'nunjucks-html-loader!./client/templates/index.njk',
});
// Optional, but highly recommended. Create a returnEntries:
// Webpack doesn't support glob paths. For the nunjucks-html-loader
// we need each path to be specified for it to work (YES, even subdirectories!)
function returnEntries(globPath){
let entries = glob_entries(globPath, true);
let folderList = new Array();
for (let folder in entries){
folderList.push(path.join(__dirname, entries[folder]));
}
return folderList;
}
module.exports = {
// You should not have this the same. This is from my site. Go down to see the important part:
entry: './client/index.js',
output: {
filename: production ? '[name]-[hash].js' : 'bundle.js',
path: __dirname + '/dist',
publicPath: 'dist/' //Important!!! : https://github.com/webpack/webpack/issues/1426
},
// #2 We load the HTMLWebpackPluginConfig
plugins: [
HtmlWebpackPluginConfig,
extractTextPlugin
],
resolve: {
extensions: ['.Webpack.js', '.web.js', '.ts', '.js', '.tsx']
},
// HERE is the important part
module: {
loaders: [
{
// HTML LOADER
// Super important: We need to test for the html
// as well as the nunjucks files
test: /\.html$|njk|nunjucks/,
use: ['html-loader',{
loader: 'nunjucks-html-loader',
options : {
// Other super important. This will be the base
// directory in which webpack is going to find
// the layout and any other file index.njk is calling.
searchPaths: [...returnEntries('./client/templates/**/')]
// Use the one below if you want to use a single path.
// searchPaths: ['./client/templates'],
}
}]
}
]
}
}
然后运行webpack,你就可以开始了?。
注意:
searchPaths: ['./client/templates'],
很重要。这是 Webpack 用于查找 index.njk 正在调用的任何文件的基本路径。尝试稍微弄乱路径以了解它是如何工作的。但不要删除它。
此外,webpack 不支持 glob 目录。我使用webpack-glob-folder-entries 编写了一个辅助函数,它为我提供了 nunjucks-html-loader 可以查看的所有子文件夹的列表。请理解,如果您不指定文件夹(即使它是子目录),它将不起作用。
换句话说,如果你想使用 _partials 文件夹(如上),并且你没有将它指定为 './client/templates/_partials',加载器将不会拾取它!
还有,
test: /\.html$|njk|nunjucks/,
不用于 index.njk,但 用于 index.njk 调用的文件,在本例中为 layout.njk。未能包含 njk 或 nunjucks 扩展将不会加载 layout.njk,它会给你一个错误。
