Leveraging TypeScript with Angular components

Situation:

  • On my website, I have a section called the "main page" where all available books are displayed.
  • The "main page" is represented by the blue box in the image provided and serves as a key component on my site.
  • Additionally, there is a separate component known as the "search" feature for users to look up specific books.

Desired outcome:

  • I aim to integrate the "Search" component (green box) within the "main page".
  • Users should be able to input search queries into the search bar and see relevant results displayed within the "main page" (Blue box).

Question:

How can I best approach this situation? I have come across suggestions regarding parent/child relationships, but I am unsure of how to apply it effectively in my scenario.

Answer №1

  1. Make sure to include an output for the search component
@Output() search: string;
  1. Bind the output to the search component template
<app-search (search)="searchStr = $event"></app-search>
  1. Utilize searchStr to filter the list (you can create a function for this, such as filtering by name)
get displayList() {
        return this.list.reduce((sum, value) => {
            if (value.name.includes(this.searchStr)) {
                sum.push(value);
            }
            return sum;
        }, []);
    }
  1. Display the filtered list
<ul>
        <li *ngFor="let item of displayList">{{ item.name }}</li>
    </ul>

Hopefully, this explanation is helpful.
