{
...
plugins: [
new HtmlWebpackPlugin({
filename: 'index.html',
// set the preconnect origins
preconnect: [
'https://api1.example.com',
'http://api2.example.com',
]
}),
// another HTML entry
new HtmlWebpackPlugin({

preconnect: [
'http://api2.example.com',
]
}),
// enabled preconnect plugin
new HtmlWebpackPreconnectPlugin(),
]
