angular cli

create new project

ng new my-new-project

start a project

cd my-new-project
# open in VisualCode just generated project ```code .```
# start locally 
ng serve
# start on specific port
ng serve --port 2222
# start and open browser
ng serve --open

build a project

ng build
ng build --prod
ng build --prod --base-href http://your-url
ng g component my-new-component
ng generate component my-new-component

create service

  • generate by cli
    ng generate service myService
  • create dummy data "src/app/my-service.service.ts"
    data=[9,8,7,6,5]
  • update "src/app/app.module.ts"
    import { MyServiceService } from './my-service.service';
    ...
    providers: [MyServiceService],

using it in model "src/app/my-component/my-component.component.ts"

import { MyServiceService } from '../my-service.service';
...
template: `
  <div>{{ this.externalService.data }}</div>
  <div>{{ this.mydata }}</div>
`,
...
export class MyComponentComponent implements OnInit{
mydata:number[]
  ngOnInit(): void {
    this.mydata = this.externalService.data
  }
  constructor(private externalService:MyServiceService){}
}

angular templates

inline template

@Component({
  selector: 'app-my-component',
  // templateUrl: './my-component.component.html',
  template: `
  <b>my-component</b> <br/>
  `,
  styleUrls: ['./my-component.component.css']
})

for loop

@Component({
  selector: 'app-my-component',
  template: `
  <b>my-component</b> <br/>
  <i>is working inline ->{{description.title+"   "+description.values}}<- </i>
  <ul>
    <li *ngFor="let each of description.values; let index = index">{{ index }} {{ each }}</li>
  </ul>
  `,
  styleUrls: ['./my-component.component.css']
})

export class MyComponentComponent {
  description:object

  constructor() { 
    this.description={
      title: "my custom properties",
      values: [5,7,9,11,13]
    }
    
  }
}

alternative template

@Component({
  selector: 'app-my-component',
  template: `
  <div *ngIf="description.customTemplate==true; else myAnotherTemplate">{{ description.values}}</div>  

  <ng-template #myAnotherTemplate>
    <ul><li *ngFor="let each of description.values"> {{ each }} </li></ul>
  </ng-template>
  `,
  styleUrls: ['./my-component.component.css']
})

export class MyComponentComponent {
  description:object
  constructor() { 
    this.description={
      title: "my custom properties",
      customTemplate: false,
      values: [5,7,9,11,13]      
    }    
  }

}

Property binding

Component --data--> View

<img src="{{ myProperty }}" >

<img [src]="myProperty" >
<button [disabled]="myProperty=='not-active-now'" >

<img bind-src="myProperty" >

Events binding

View --event--> Component

@Component({
  selector: 'app-my-component',
  template: `
    <button (click)="myEvent($event)">click event</button>
  `,
  styleUrls: ['./my-component.component.css']
})

export class MyComponentComponent {
  myEvent(event:MouseEvent){
    console.log(event)
    window.alert(event)
  }
}

Styles

inline style

@Component({
  selector: 'app-my-component',
  template: `
    <button>my button</button>
  `,
  styles: [`
   button {
     font-weight: bold;
     color: red;
   }
  `]
})

Animation

installation

 npm install @angular/animations@latest --save

component

import { trigger, state, style, transition, animate, keyframes } from '@angular/animations'

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
  animations: [
    trigger('myOwnAnimation',
            [
            state('small', style({transform: 'scale(1)'})),
            state('bigger', style({transform: 'scale(2)'})),
            transition(
              'small <=> bigger', 
              animate('300ms', style({transform: 'translateY(100px)'}))
            )
            ]
    )
  ]
})
export class AppComponent {
  state: string = "small"
  animateMe(){
    this.state = (this.state === 'small'? 'bigger' : "small")
  }
}

template

    <p [@myOwnAnimation]='state'  (click)="animateMe()" style="text-align: center"> animation</p>
