......and I've no idea what the hell I'm doing. ????
Okay let me explain I'm going back over a Wordpress course I did on Udemy where the now AWOL instructor implemented a automated workflow for us to use whereby anytime we typed PHP or JS the webpage would reload automatically, and it's working, actually it's working too fast for me. This time round for some reason it's driving me bonkers cos when I'm writing my code the page is recompiled before I can even finish typing a complete line of code! The webpage generates a parse error and I have to manually refresh the page when I'm done to clear the error as it doesn't get automatically refreshed due to the error, which sort of defeats the purpose of the automation.
The automated workflow was basically implemented by doing the following:
- I've installed 2 files package.json & webpack.config.js into my theme
folder - Then I ran
npm run devFast - Then by changing functions.php we got the WP theme to use the Node
generated assets. Node serves up all of the JavaScript and CSS within
one single bundled file, bundled.js
I've no idea where to start in asking for help with this so thought I'd start here. As I say any help with this would be appreciated even if you just signpost me. I'm also using Local by Flywheel to host the site locally and this has been a great tool.
If it helps my webpack file is ...

SUPER IMPORTANT: This config assumes your theme folder is named
exactly 'fictional-university-theme' and that you have a folder
inside it named 'bundled-assets' - If you'd like to adapt this
config to work with your own custom folder structure and names
be sure to adjust the publicPath value on line #116. You do NOT
need to update any of the other publicPath settings in this file,
only the one on line #116.

If you want the browser to also perform a traditional refresh
after a save to a JS file you can modify the line directly
below this comment to look like this instead. I'm using this approach
instead of just disabling Hot Module Replacement beacuse this way our
CSS updates can still happen immediately without a page refresh.
If you're using a slower computer and the new bundle is not ready
by the time this is reloading the browser you can always just set the
"hot" property a few lines below this to false instead of true. That
will work on all computers and the only trade off is the browser will
perform a traditional refresh even for CSS changes as well.

My Answer:
PHP is a popular server-side scripting language that is used to create dynamic web pages. It is often used in conjunction with HTML to add functionality to websites, such as processing form data, interacting with databases, and generating dynamic content. PHP code is embedded within HTML code and is executed on the server before the page is sent to the client's web browser.
