how can i make build for this project?

[FireMonkey92]

Sorry , but i am new at using webpack and I want to create a build for this project, i tried putting script under package.json file like

"scripts": {
"dev": "nodemon index.js --ignore client",
"build": "webpack"
},

and in webpack config file is like,
module.exports = {
entry: './client/index.js',
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'build.js'
},
module: {
loaders: [
{
test: /.js$/,
loader: 'babel-loader'
}
],
rules: [
{
use: 'babel-loader',
test: /.js$/,
exclude: /node_modules/
},
{
use: ['style-loader', 'css-loader'],
test: /.css$/
}
]
},
plugins: [
new HtmlWebpackPlugin({
template: 'client/index.html'
})
]
};

I can not run the build, I have no idea whether I have created the build correctly or not. Please guide me to create the build for this project.
