Recommend an image resizer and HTML markup generator?

Question

HTML

There is a picture image.jpg large enough in size 4000*5000 px, a config of the necessary sizes for breakpoints {1200: 900px, 768: 700px, 1: 500px}and a dpr config {1, 2, 3}.
You need to get a pack of pictures according to the specified sizes:

[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]

and HTML markup (just output to the console)

<picture>
 <source media="(min-width: 1200px)" srcset="[email protected] 1x, [email protected] 2x, [email protected] 3x">
 <source media="(min-width: 768px)" srcset="[email protected] 1x, [email protected] 2x, [email protected] 3x">
 <img srcset="[email protected] 1x, [email protected] 2x, [email protected] 3x">
</picture>

A similar task is easily solved in a CMS, but sometimes you need a "manual", console solution, preferably on node.js.
There are interesting options on the Internet https://github.com/felixrieseberg/responsive-image... https://github.com/TrigenSoftware/gulp-srcset, https://github.com/mahnunchik/gulp-responsive only for resize, but I want a comprehensive solution for maximum automation and without bicycle building.
Recommend if you have seen something similar?
