How to glue (concatenate) files inscribed in html?

Question

JavaScript

Hey!
Prompt a console (CLI) tool on NodeJS for automatic merging of files specified in HTML.
For example, there is an index.html
it contains:

<!-- concat js/all.js -->
<script src="bower_components/jquery/dist/jquery.js"></script>
<script src="bower_components/bootstrap-sass/assets/javascripts/bootstrap.js"></script>
<!-- endconcat -->

with one console command, it all turns into the all.js file in the js directory
and in index.html

<!-- concat js/all.js -->
<script src="bower_components/jquery/dist/jquery.js"></script>
<script src="bower_components/bootstrap-sass/assets/javascripts/bootstrap.js"></script>
<!-- endconcat -->

turns into
<script src="js/.js"></script>
Gulp and other assemblers are not suitable :(
many small projects, it is expensive to produce node_modules and other files everywhere, and for a long time

Answer 1

Fortunately, I found what I was looking for
https://github.com/digisfera/useref-file
wrapper for userref, which Gulp also has by the way

Well, that's exactly what they're designed for. And if you don’t know how to cook them, then it’s time to learn.
Here, for example, is a plugin for Grunt , which only needs to slip in a suitable regular expression. No one will make a separate solution for replacing strings, everyone understands that this should be in task runners.

Procreate? And gitignore was not taught to do unnecessary things?)
