Angular2 App – Bootstrap TypeScript Product Management

Happy coding. Today I am going to show on how to build a front end UI using Angular JS – mostly known as Angular2, and Typescript.


Angular is a front end framework that helps you to work with DOM is the good manner by the use of the component. Angular is components. Read their docs for more information

Here we start
First, we will need to install Angular on your machine. Follow the guideline from on how to install Angular on your computer.

Don’t forget read document dont just follow commands. This will help to understand what you are doing

You can also download a start up project from my git repo that has been already configured by Deborah. On this link


Made pipe that helps on filtering product that using.


name: 'productFilter'

export class ProductFilterPipe implements PipeTransform {

transform(value: IProduct[], filterBy: string):  IProduct[] {
filterBy = filterBy ? filterBy.toLocaleLowerCase() : null;
return filterBy ? value.filter((product: IProduct) =>
product.productName.toLocaleLowerCase().indexOf(filterBy) !== -1) : value;

Filter variable

export class ProductListComponent implements OnInit {
pageTitle: string = "All Product List";
imageWidth: number = 40;
imageMargin: number = 2;
showImage: boolean = false;
listFilter: string;
products: IProduct[];
constructor(private _productService: ProductService) {

Making the use of the filter in the view

type="text" [(ngModel)] = 'listFilter'

Filter by: {{listFilter}}
