我正在尝试使用webpack-hot-middleware来热重新加载我的应用程序的模块。我也在使用webpack-dev-middleware。
这是我的设置。

app.listen(port, function(err) {
if (err) {
console.log(err);
} else {
console.log("App listening on port " + port);
}
});
设置无效。我更新代码时编译工作正常，当我刷新浏览器时，执行新的应用程序代码。但是模块没有被替换。
请帮我解决这个问题。谢谢！

如果您按照the fine manual中的说明进行操作，在您的情况下会转换为以下内容：
let compiler = webpack(config);
app.use(webpackMiddleware(compiler, {
noInfo : false,
publicPath : config.output.publicPath
}));
app.use(webpackHotMiddleware(compiler, {
'log' : console.log,
'path' : '/__webpack_hmr',
'heartbeat' : 10 * 1000
}));
我不确定您传递给webpackHotMiddleware的各种选项（log已默认为console.log，因此您可以将其删除，并且您应该使用默认为path而不是自己设置。
