Hot Module Replacement '[HMR] Waiting for update signal from WDS...' forever, how to enable Hot Module Replacement or send signal from Webpack Dev Server?
I want Hot Module Replacement be enabled.
Therefore, I set hot: true
in webpack.config.js.
I stuck at
[HMR] Waiting for update signal from WDS...
I expected to see
[HMR] Waiting for update signal from WDS...
[WDS] Hot Module Replacement enabled.
I tried webpack serve --hot --inline
command, but I got nothing...
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
I use 'react-hot-loader'.
import { hot } from 'react-hot-loader/root';
// some codes
export default hot(App);
if I change code 'webpack-dev-server' shows
i 「wdm」: Compiling...
./src/App.tsx 1.62 KiB [built] [code generated]
i 「wdm」: Compiled successfully.
