Angular 2 filter/search list

Question

I'm looking for the angular 2 way to do this.

I simply have a list of items, and I want to make an input whos job is to filter the list.

<md-input placeholder="Item name..." [(ngModel)]="name"></md-input>

<div *ngFor="let item of items">
{{item.name}}
</div>

What's the actual way of doing this in Angular 2? Does that requires a pipe?

Answer 1

Search by multiple fields

Assuming Data:

items = [
  {
    id: 1,
    text: 'First item'
  },
  {
    id: 2,
    text: 'Second item'
  },
  {
    id: 3,
    text: 'Third item'
  }
];

Markup:

<input [(ngModel)]="query">
<div *ngFor="let item of items | search:'id,text':query">{{item.text}}</div>

Pipe:

import {Pipe, PipeTransform} from '@angular/core';

@Pipe({
  name: 'search'
})
export class SearchPipe implements PipeTransform {
  public transform(value, keys: string, term: string) {

    if (!term) return value;
    return (value || []).filter(item => keys.split(',').some(key => item.hasOwnProperty(key) && new RegExp(term, 'gi').test(item[key])));

  }
}

One line for everything!
