Create a package.json for wp theme development

I am not a programmer, but am designing a simple wordpress theme for my business. I'm looking to hire a programmer to help me with my development and distribution environment (e.g. package.json, and gulpfile.mjs, webpack, yarn or other) files that will have no severe vulnerabilities. I prefer gulp and babel but other methods of getting the desired outcome are welcome.


The the proposed project file will have a script for: 1) Development (called "start"); 2) Distribution ("build"); and 3) Packaging ("zip"). The dev tools into these categories as follows:

Development (start):
* Compile SCSS to CSS.
from root\src\main.scss to root\build\main.css
* Transpile and bundle JavaScript files.
from root\src\index.js (which is a list of js files) to root\build\bundle.js (one file with the contents of the files in root\src\index.js)
* Copy necessary assets (fonts, images, video)
copy relevant folders from root\src\.. to root\build..
Copies only new or updated files.
* Optimize images.
* Sync browser for live reload and watch for changes (SCSS, PHP, JS).

Distribution (build):
* Delete contents of build directory and its sub-directories (to clear clutter from earlier work)
* Copy (recreate) necessary assets (fonts, images, video) from src to build folder.
* Compile and minify SCSS to CSS.
* Transpile and minify JavaScript files.
* Optimize images for production.
* Ensure that the build output is ready for deployment.

Packaging (zip):
I have already done this in the way I wish, so you may not have to. I will send it to you if you take on this project.


My environment:
Windows 11
XAMPP 3.3.0
Node 20.13.1
npm 10.7.0
Visual Studio Code. (Terminal)


The root structure of my project is as follows:

P.S. If this works out well, I may have additional tasks (e.g., debugging, testing, and additions to the theme) that I would like help with.
