对不起,我知道这已经被问了很多次了,但是在我看来,所有答案都没有用。
这种情况是,我正在编写一个Outlook加载项(使用此处的说明:https://docs.microsoft.com/en-us/outlook/add-ins/addin-tutorial),它包含来自node_modules的css文件,并使用npm start运行-显然,这对开发工作正常,但是使用着眼于生产,我尝试了npm build并运行良好,除了它保留了对node_modules /的所有引用不变之外,不用说,由于该文件夹不存在,这会破坏生产文件。
index.html(不相关的部分,被截断)
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

在理想情况下,我将使用条件编译语句,该语句将交换本地链接,并在生产构建中将其替换为CDN链接(但是这种方法看起来非常复杂)
因此,删除CDN链接很好,但是如何获取webpack将“ node_modules / office-ui-fabric-js / dist / css / fabric.min.css”移动到“ assets / css / fabric.min” .css'?
webpack.config.js
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');
module.exports = {
entry: {
polyfill: 'babel-polyfill',
app: './src/index.js',
'function-file': './function-file/function-file.js'
},
module: {
rules: [
{
test: /\.css$/,
loader: "style-loader!css-loader"
},
{
test: /\.js$/,
exclude: /node_modules/,
use: 'babel-loader'
},
{
test: /\.html$/,
exclude: /node_modules/,
use: 'html-loader'
},
{
test: /\.(png|jpg|jpeg|gif)$/,
// exclude: /assets/,
use: [
{
loader : 'file-loader',
options :
{
name: "/assets/[name].[ext]"
}
}
],
}
]
},
plugins: [
new HtmlWebpackPlugin({
template: './index.html',
chunks: ['polyfill', 'app']
}),
new HtmlWebpackPlugin({
template: './function-file/function-file.html',
filename: 'function-file/function-file.html',
chunks: ['function-file']
}),
new CopyWebpackPlugin(
[{ from: './assets', to: './assets', toType : 'dir' }]
),
]
};
任何帮助都会感激不尽,我是一名PHP开发人员,虽然我对Javascript更加熟悉,但是整个webpack和node对我来说都是新的,我发现学习曲线有些陡峭!
TIA

答案 0 :(得分:0)
使用webpack,必须将所有资产(任何扩展名)都包含在入口点中(对于您而言,可以添加到src/index.js
中)。通过这样做,webpack可以了解您正在使用的所有依赖项,并正确地解析/编译/捆绑它们,并且您不会遇到这些类型的问题。您不得手动将链接添加到index.html
,因为这样做会使webpack无法识别您要添加的内容。
根据您的情况,正确的方法是:
index.js
:
import "office-ui-fabric-js/dist/css/fabric.min.css"
import "office-ui-fabric-js/dist/css/fabric.components.css"
...
这些文件将位于其他块中,并由Html Webpack plugin
添加。
更新:
要从js文件中提取CSS,请执行以下操作:
const HtmlWebpackPlugin = require('html-webpack-plugin');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const ExtractTextPlugin = require("extract-text-webpack-plugin/");
module.exports = {
entry: {
polyfill: 'babel-polyfill',
app: './src/index.js',
'function-file': './function-file/function-file.js'
},
module: {
rules: [
{
test: /\.css$/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: 'css-loader'
})
},
{
test: /\.js$/,
exclude: /node_modules/,
use: 'babel-loader'
},
{
test: /\.html$/,
exclude: /node_modules/,
use: 'html-loader'
},
{
test: /\.(png|jpg|jpeg|gif)$/,
// exclude: /assets/,
use: [
{
loader : 'file-loader',
options :
{
name: "/assets/[name].[ext]"
}
}
],
}
]
},
plugins: [
new ExtractTextPlugin("styles.css"),
new HtmlWebpackPlugin({
template: './index.html',
chunks: ['polyfill', 'app']
}),
new HtmlWebpackPlugin({
template: './function-file/function-file.html',
filename: 'function-file/function-file.html',
chunks: ['function-file']
}),
new CopyWebpackPlugin(
[{ from: './assets', to: './assets', toType : 'dir' }]
),
]
};
