我有一个服务器端渲染应用程序，我正在尝试弄清楚如何为此实现热重新加载，这与webpack-dev-server为您所做的相同。
我遇到了webpack.config。我试图实现这一点，但没有成功。这是我serverConfig中的内容。我在同一个文件中也有一个名为const isProduction = (process.env.NODE_ENV === 'production');
const clientConfig = {
entry: [
'webpack-hot-middleware/client?http://localhost:3000',
'./src/client/index.js',
],
output: {
path: path.join(__dirname, 'public'),
filename: 'bundle.js',
publicPath: '/public'
},
module: {
rules: [
{
loader: 'babel-loader',
test: /\.js$/,
exclude: /node_modules/
},
{
test: /\.s?css$/,
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: [{
loader: 'css-loader',
options: {
sourceMap: true,
importLoaders: 2
}
},
{
loader: 'postcss-loader',
options: {
plugins: [autoprefixer()],
sourceMap: true
}
},
{
loader: 'sass-loader',
options: {
sourceMap: true
}
}]
})
}
]
},
devtool: isProduction ? 'source-map' : 'inline-source-map',
optimization: {
minimizer: [
new UglifyJsPlugin({
test: /\.js$/,
exclude: /node_modules/,
parallel: true,
sourceMap: true,
cache: true,
}),
new OptimizeCSSAssetsPlugin({})
]
},
plugins: [
new ExtractTextPlugin('styles.css'),
new webpack.DefinePlugin({
ISCLIENT: "true"
}),
new webpack.HotModuleReplacementPlugin(),
new webpack.NoEmitOnErrorsPlugin()
],
的配置，用于服务器端渲染。
const webpack = require('webpack');
const webpackConfig = require('../../webpack.config');
const compiler = webpack(webpackConfig);
app.use(require("webpack-dev-middleware")(compiler, {
noInfo: true,
publicPath: webpackConfig.output.publicPath
}));
app.use(require("webpack-hot-middleware")(compiler));
};
我的server.js
dev我从package.json
运行 "scripts": {
"dev": "npm-run-all --parallel dev:*",
"dev:server": "nodemon --watch build --exec \"node build/server.js\"",
"dev:build-server-client": "webpack --mode development --watch",
"build:dev": "webpack --mode development",
"build:prod": "cross-env NODE_ENV=production webpack -p",
"start": "node build/server.js",
"heroku-postbuild": "npm run build:prod"
},
脚本
dev出于某种原因，每当我运行dev:server或webpack-hot-middleware脚本时，节点总是给我一个错误：
＆＃39;提供的值＆＃34; \\ public＆＃34;不是一条绝对的道路。
＆＃39;提供的值＆＃34; \\ build＆＃34;不是一条绝对的道路。 ＆LT;＆LT; serverConfig中
有趣的是，当我删除与select distinct 'Category' as parent, 'Subcategory' as child
from (select distinct category, subcategory from otm) as cols
group by category
having count(subcategory) > 1
union
select distinct 'Subcategory' as parent, 'Category' as child
from (select distinct category, subcategory from otm) as cols
group by subcategory
having count(category) > 1
union
select distinct 'Category' as parent, 'Product' as child
from (select distinct category, product from otm) as cols
group by category
having count(product) > 1
union
select distinct 'Product' as parent, 'Description' as child
from (select distinct product,description from otm) as cols
group by product
having count(description) > 1;
相关的所有内容时，一切正常，当然没有热重定位部分。任何人都知道这里的问题是什么？
