热模块更换'[HMR]正在等待WDS的更新信号…'永远，如何启用热模块更换或从Webpack开发服务器发送信号？
我希望启用热模块更换。因此，我在webpack.config.js.中设置了hot: true
我被卡住了
[HMR]正在等待WDS的更新信号。。。
我希望看到
[HMR]正在等待WDS的更新信号
[WDS]热模块更换已启用。
我尝试了webpack serve --hot --inline命令，但一无所获。。。
webpack.config.js
// Paths
const path = require('path');
const srcPath = path.join(__dirname, 'src');
const distPath = path.join(__dirname, 'dist');
const publicPath = path.join(__dirname, 'public');
// Plugins...
// Modules
module.exports = {
mode: 'development',
entry: path.join(srcPath, 'index.tsx'),
output: {
path: distPath,
filename: 'bundle.js',
},
module: {
rules: [
// TypeScript
{
test: /.(j|t)sx?$/,
exclude: /node_modules/,
use: ['babel-loader']
},
},
// resolves...
devServer: {
contentBase: distPath,
historyApiFallback: true,
hot: true,
inline: true,
writeToDisk: true
},
// plugins...
.babelrc
// .babelrc
{
"presets": [
"@babel/preset-env",
"@babel/preset-react",
"@babel/preset-typescript"
],
"plugins": [
"react-hot-loader/babel"
]
}
App.tsx
我使用"react hot loader"。
import { hot } from 'react-hot-loader/root';
// some codes
export default hot(App);
如果我更改代码"webpack dev-server"显示
i<wdm：编译>
/src/App.tsx 1.62 KiB[builded][code generated]
i"wdm"：编译成功。
这是package.json

有一个错误https://github.com/webpack/webpack-dev-server/issues/2758当将browserslist与webpack-dev-server和webpack一起使用时，您可以将target: 'web'设置为解决该问题，直到webpack-dev-server v4退出。
