Add Buttons In Product List

Here’s an example of how you can create a “Buy” button, “Cart” page, and “View Details” page in an Angular app:

  1. In your product component’s template, create a “Buy” button for each product. This button will call a function in the product.component.ts file that will handle the logic for adding the product to the cart.
<div >
                    <button class="btn btn-warning" type="submit"
                       (click)="addToCart(product.id)"><i class="bi bi-cart-plus-fill"></i></button>
                        <button class="btn btn-warning m-1" type="submit"
                        [routerLink]="['/single-product',product.id]"><i class="bi bi-eye-fill"></i></button>
                    <button class="btn btn-warning m-1" type="submit"
                        onClick="window.open('https://shop.softwaretechit.com')">Buy Now</button>
                </div>

In the product.component.ts file, create the addToCart() function that will take in the selected product as a parameter and add it to an array (or any data structure of your choice) that will represent the cart.

import { Component, OnInit } from '@angular/core';
import { ProductService } from './product.service';

@Component({
  selector: 'app-product',
  templateUrl: './product.component.html',
  styleUrls: ['./product.component.css']
})
export class ProductComponent implements OnInit {
  products: any;
  cart: any[] = [];

  constructor(private productService: ProductService) { }

  ngOnInit() {
    this.productService.getProducts().subscribe(data => {
      this.products = data;
    });
  }

buyProduct(product) {
    // code to buy the product
  }

  addToCart(product) {
    this.cart.push(product);
  }

  viewDetails(product) {
    // Navigate to the view details page and pass the selected product as a parameter
  }
}
  1. Create a new component called cart using the command ng generate component cart
  2. In the cart component’s template, display the items in the cart by looping through the cart array and displaying their information.
  3. Create a new component for the product’s details page, let’s call it product-details / single-product. In the viewDetails function of product component, we are using router to navigate to this new component with the product’s id as a parameter.
ng generate component product-details

In the product-details component class (product-details.component.ts), you can retrieve the product’s ID from the route parameters and use it to make an API call to retrieve the product’s details. And use the product-details.component.html to display the details of the product.

Finally, in your app-routing.module.ts file, add a new route for the product-details component, and include the parameter for the product’s ID.

import { ProductDetailsComponent } from './product-details/product-details.component';

const routes: Routes = [
  { path: 'product-details/:id', component: ProductDetailsComponent },
  // other routes
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

This is a basic example and you can customize the implementation as per your needs. You can use different libraries or services to handle the cart and the purchase process.
