This demo is based on laravel-mix starter kit and its using ejs-compiled-loader to compile ejs files. other functionality and document should work as laravel-mix documentation.

You can find step by step guide from

npm install

npm start

npm run prod

new HtmlWebpackPlugin({
    template: "ejs-compiled-loader!./src/index.ejs",
    filename: "index.html",
    inject: false
})

this will generate index.html file in dist folder and header/footer will be included, please check index.ejs file content.
