How to combine several files into one in ASP NET Razor or gulp.js and then load the generated file?

Question

ASP.NET

How to generate html only once in the Razor template engine on ASP NET MVC Core and then issue it every time?
You just need to collect html files into one big one and minimize it.
In Razor I write:
@Html.Partial("~/Views/Main/Templates/About.cshtml")
but every request does an action and I would like to build the file once.
Or how to do it with gulp.js once and then output this file?

Answer 1

Read about webpack.

Answer 2

Well, you have the correct tag, gulp.js. Read the docks - they are shit, but after them you will at least have the right questions. In addition, they have typical examples.
