I'm using Webpack 5 and cannot set dev-server to pick up the latest changes immediately. That's why when I have any changes in my project I should do yarn build first and then yarn dev every time. I've already seen the same question here Webpack-dev-server doesn't pick up latest changes, but writeToDisk: true shows an error in the console. I've attached my webpack.config.js file.
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const miniCss = require('mini-css-extract-plugin');
module.exports = {
entry: { main: './src/index.js' },
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'main.js',
publicPath: ''
},
mode: 'development',
devServer: {
static: {
directory: path.join(__dirname, "dist")
},
compress: true,
port: 8080,
devMiddleware: {
publicPath: "//localhost:8080",
},
hot: "only",
open: true
},
module: {
rules: [
{
test: /\.js$/,
use: 'babel-loader',
exclude: '/node_modules/'
},
{
test: /\.pug$/,
loader: 'pug-loader',
options: {
pretty: true
}
},
{
test: /\.css$/,
use: [MiniCssExtractPlugin.loader, {
loader: 'css-loader'
}]
},
{
test: /\.(s*)css$/,
use: [
miniCss.loader,
'css-loader',
'sass-loader',
]
},
{
test: /\.(png|svg|jpg|gif|woff(2)?|eot|ttf|otf)$/,
type: 'asset/resource'
},
]
},
plugins: [
new HtmlWebpackPlugin({
template: './src/pages/page/page.pug',
filename: 'index.html'
}),
new MiniCssExtractPlugin(),
new miniCss(),
]
}
Your issue is most likely with hot: "only". According to https://webpack.js.org/configuration/dev-server/ you will not see a page refresh on build failures if it's not hot: true.
Other than that I don't see anything obviously wrong with your code. I suspect that if you change it to hot: true it should refresh the page and that you have some other build failure.
