How to pass value from one component to another? (Angular) - html

Question

I just recently started learning Angular and I have a question. I want to implement a search method to search for a product on my site, I made search.pipe.ts, which works, but the input for input is in the header.component.ts component, and the products array is in the car-list.component.ts component.
car-list.component.html
<div *ngFor="let car of cars | paginate: { itemsPerPage: pageNumber, currentPage: currentPg} | **search:searchStr**" class="col-md-3">
<div class="product box">
<img src="{{'data:image/jpg;base64,' + car.image }}" alt="">
<h3>{{ car.name }}</h3>
<div class="price">{{ car.price | currency:'USD' }}</div>
<button class="btn btn-primary btn-sm">Add to cart</button> <!--(click)="addToCart(tempProduct)"-->
</div>
<br>
</div>
header.component.html
<form class="d-flex me-5">
<input type="text" class="form-control me-2" placeholder="Search cars...">
</form>
header.component.ts
export class HeaderComponent implements OnInit {
searchStr: string = '';
constructor() {
}
ngOnInit(): void {
}
}
search.pipe.ts
#Pipe({
name: 'search'
})
export class SearchPipe implements PipeTransform {
transform(cars: any[], value: any) {
return cars.filter(car => {
return car.name.includes(value);
})
}
}
I want the input values ​​from the header component to be passed to the car-list component so that I can find the product I need.

Answer 1

In this case you can use a shared service where you can pass data from your header component and load that data in your products component.
For further reference - Angular 4 pass data between 2 not related components

Answer 2

use #Input and #Output decorators to communicate between components
