我在ejs上看过这篇文章。但是,我如何与webpack实现同样的目标呢?
我试图结合html-webpack-plugin使用nunjucks加载程序,但是我得到了以下错误:[nunjucks-loader] non-web targets are not supported。
这是我的密码:
下面是配置:
const HtmlWebpackPluginConfig = new HtmlWebpackPlugin({
//template: './client/index.html',
filename: 'index.html',
inject: 'body',
template: 'nunjucks-html-loader!./client/templates/index.njk',
});
module: {
loaders: [
{
test: /\.html$/,
use: ['html-loader']
},
{
test: /\.|njk|nunjucks$/,
use: ['nunjucks-loader']
}]
};发布于 2017-10-09 22:34:44
这可能是很长的时间,但请容忍我:
问题是nunjucks加载程序将其作为JavaScript文件(根据第一段)传递。
相反,使用nunjucks-html-加载程序。
使用npm或纱线安装:首先,我们安装nunjucks-html-加载程序:
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)
npm i webpack-glob-folder-entries -D或
yarn add webpack-glob-folder-entries -D然后,如果考虑到以下文件夹结构:
- client/
-templates/
-index.njk
-layout.njk
-_partials/
- webpack.config.js在index.njk内部,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 %}我们可以使用以下设置配置webpack:
//#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$|njk|nunjucks/,
use: ['html-loader',{
loader: 'nunjucks-html-loader',
options : {
// Other super important. This will be the base
// directory in which webpack is going to find
// the layout and any other file index.njk is calling.
searchPaths: [...returnEntries('./client/templates/**/')]
// Use the one below if you want to use a single path.
// searchPaths: ['./client/templates'],
}
}]
}
]
}
}然后运行webpack,你就可以走了。
注意:
searchPaths: ['./client/templates'],很重要。下面是Webpack将使用的基本路径,用于查找index.njk正在调用的任何文件。试着把这条路弄乱一点,以了解它是如何工作的。但是不删除它。
此外,webpack 不支持目录。我使用webpack-glob-folder-entries编写了一个帮助函数,它为我提供了nunjucks加载程序可以查看的所有子文件夹的列表。请理解,如果您不指定文件夹(即使它是一个子目录),它将而不是工作。
换句话说,如果您想要使用_partials文件夹(如上面所示),并且不将其指定为'./client/templates/_partials',加载程序将不会选择它!
另外,
test: /\.html$|njk|nunjucks/,不是用于index.njk,而是用于index.njk调用的文件,在本例中是layout.njk。未能包含njk或nunjucks扩展将不会加载layout.njk,它将给您一个错误。

我在寻找解决方案的时候也遇到了这个问题,被接受的解决方案对我不起作用,所以我觉得把我的解决方案添加到混合方案中是很合适的,比如如何在web包中使用nunjucks作为条目。
我一直遇到有多个入口点的问题,直到最后我找到了下面的回购并修复了这个问题。
注意,在撰写本文时,npm注册中心尚未通过最近的代码更改进行更新,因此您需要从package.json直接链接到回购程序。
这是我的:概念库的证明
下面是我写的webpack配置,以供参考:
const webpack = require('webpack');
const path = require('path');
const fs = require('fs');
const HtmlWebpackPlugin = require('html-webpack-plugin')
// Notice, the below methods searches src/components and adds a HtmlWebpackPlugin for each folder
// This is required, even for subfolders otherwise you nunjuck includes will nto work.
const d = './src/components';
const entryFolders = fs.readdirSync(path.resolve(d))
.map(f => path.join(__dirname, path.join(d, f)) )
.filter(f => fs.statSync(f).isDirectory());
function getHtmlComponentPlugins() {
return entryFolders.map(templatePath => {
const name = templatePath.split('\\').pop()
const sett = {
customData: { foo: 'bar' },
filename: path.relative(__dirname, templatePath.replace('src\\', '') + `\\${name}.html`),
template: templatePath + `\\${name}.njk`
};
return new HtmlWebpackPlugin(sett)
});
}
module.exports = function() {
return {
devtool: '#source-map',
mode: 'development',
entry: [
'./src/index.js'
],
output: {
path: path.resolve(__dirname, 'dist')
},
resolve: {
extensions: [ '.js' ]
},
module: {
rules : [
{
test: /\.(njk|nunjucks|html|tpl|tmpl)$/,
use: [
{
loader: 'nunjucks-isomorphic-loader',
query: {
root: [
path.resolve(__dirname, 'src'),
].concat(entryFolders)
}
}
]
}
]
},
plugins: [
new HtmlWebpackPlugin({
customData: { foo: 'bar' },
filename: 'index.html',
template: 'src/index.njk'
})
].concat(getHtmlComponentPlugins())
};
}

与其将加载程序(nunjucks- loader )和Webpack插件(HtmlWebpackPlugin)混合在一起,不如让女妖-webpack-插件试试。
它看起来像是HtmlWebpackPlugin的一个很好的替代品!
