From the course Angular and NodeJS: A Practical Guide with Typescript by Antonio Papa
https://www.udemy.com/course/angular-node-admin/
and
The Complete Angular & NestJS Course
https://www.udemy.com/course/the-complete-angular-nestjs-course/

Added my notes and every command used in the project, hope you find this useful in learning about Angular. :)

To not generate test files (doesn't work: Data path "" must NOT have additional properties(skipTests).):
"@schematics/angular:component": {
  "skipTests": true
},
"@schematics/angular:module": {
  "skipTests": true
},
"@schematics/angular:service": {
  "skipTests": true
},

npm i c3
npm i -D @types/c3

---Angular Fixes

Fix: error TS2564: Property has no initializer and is not definitely assigned in the constructor.
tsconfig.json (under compilerOptions):
    "noImplicitReturns": false,
    "strictPropertyInitialization": false,
	
---Angular2+ Concepts

<router-outlet> => loads (child) components dynamically
	-master-detail

normal forms => 2 way data binding
reactive forms

generated services can be injected as a dependency in components

@Input - to pass variables from parent component to child component (via html attribute)
	-So only one component calls api once instead of multiple components calling the same api.
	
Interceptors => to do something additional for every request made. e.g. add credentials (cookies)

Event Emitter => Like redux/vuex to store global data (for component events to update other components)
	-Emit and Subscribe to an event
	-So only one component calls api once instead of multiple components calling the same thing.

[routerLink] vs routerLink
	-brackets means you pass in variable (dynamic)
	-w/o brackets means a string
	
(click/submit)
	-parentheses mean event, which will trigger/call a function.
	
<ng-container></ng-container> doesn't show as an html element
