Utilizing Filters (Pipes) in Angular 2 Components without Involving the DOM Filters

When working in Angular 1, we have the ability to use filters in both the DOM and Typescript/Javascript. However, when using Angular 2, we utilize pipes for similar functionality, but these pipes can only be accessed within the DOM. Is there a different approach to incorporating pipe functions in Typescript (components)? If anyone has insight on this matter, please provide assistance.

For example:

<div *for="let item of items">
    {{item.price | priceFilter }}
</div>

I have created a custom pipe named priceFilter, but I am interested in achieving the same filtering capabilities in Javascript/Typescript.

Answer №1

To effectively filter data within your component, consider utilizing the pipe method in the following manner:

const filteredValue = new CustomFilterPipe().transform(this.data.value);

For this example, it is presumed that the exported pipe class is named CustomFilterPipe. Ensure that you also import CustomFilterPipe into your component.
