I faced a problem that I couldn't use vercel environment variables with a deployed angular app. I used to write my sensitive information in an env file while writing backend code and I forgot that browsers don't support the process module. So I searched for a while and got the result I want by following these steps:

install the next package:

npm install --save-dev @angular-builders/custom-webpack

open angular.json and use "builder": "@angular-builders/custom-webpack:browser" instead of "builder": "@angular-devkit/build-angular:browser"
add customWebpackConfig key in options object with a path to a file that you will create later:
```
 "options": { "customWebpackConfig": {"path": "custom-webpack-config.js"} }
```

	// adding branch2 commets to branch1
	$ git checkout <branch1>
	$ git merge <branch2>

	// merging a branch to main
	$ git checkout main
	$ git merge <branch needed to be merged to main>

	As described in this file, all windows store apps are blocked from accessing localhost, you need to enable that by cmd.

	To give Nightingale the permission to access your localhost you need to open cmd in administrator mode and enter that command:

	rem:
	- relative to the font size of the root elemnt (initially 1rem = 16px)
	- better for font-size as it works well with browser font-size preferences (user may change his default font-size value)
	- working with rem can be by setting font-size value in the HTML element to be 62.5% ( now 16px = 1.6rem & 37px = 3.7rem ...)
	- can be used with margin/padding if you don't want them to change with the font-size space of the element
	- if you set *{margin-top:1rem} then all elements has the same top spaceing

	em:
	- relative to the font-size of its direct or nearest parent
	- better to be used with media-query values as px & rem have some compatibility issues for some browsers
