});
module.exports = {
output: {
path: path.join(__dirname, './'),
publicPath: '/'
},
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader"
}
},
{
test: /\.html$/,
use: [
{
loader: "html-loader",
options: { minimize: true }
}
]
},
{
test: /\.css$/,
use: [
{
loader: "style-loader"
},

options: {
modules: true,
importLoaders: 1,
localIdentName: "[name]_[local]_[hash:base64]",
sourceMap: true,

new HtmlWebPackPlugin({
template: "./src/index.html",

}),
new Dotenv()
],
devServer: {
historyApiFallback: true,
}
};

If you can share the error log, I may tell what is the real problem. But current config is missing for an entry point. If your application is a single page app, do it like the following code;
module.exports = {
entry: path.join(__dirname, "src", "index.js"),
...
}
if you are building multi page application do it like the following code;
module.exports = {
entry: {
pageOne: path.join(__dirname, "src", "pageOne", "index.js"),
pageTwo: path.join(__dirname, "src", "pageTwo", "index.js"),
pageThree: path.join(__dirname, "src", "pageThree", "index.js")
}
...
}

For anyone arriving here and having this issue, I had this exact problem where files in my 'src/components' directory weren't hot reloading.
I was able to fix it when I saw in the log that webpack was looking for the directory 'src/Components' for some reason, so I changed the name of the components directory to something totally different like 'placeholder' then changed it back to 'components' and ran a fresh install.
