we are currently working on a project of restaurants management, we are using laravel/mysql on the backend and we are looking for the best way to manage invoices pdfs , for now we are just storing theme in a public folder but i think this not a prefect way. we think to send the just the order data to frontend and generate the pdf when the user click on a download button but it's still not efficient, so i need an idea to manage pdf invoices and get theme any time the user wanted them without hurt performance.
