Angular filter array data by searching in input. In this tutorial, we will learn how a search input box is added to the Angular 13 app to filter data into an array.

Sometimes you can have a long list of items or data in tabular form which is added to the component for users. In that case, adding a simple filter search bar to your Angular apps can improve into a boon for filtering the set of information the user needs.

Angular 13 Filter Array Data Example

Follow the following steps to filter array data by searching in input in angular 13 apps; as follows:

Step 1 – Create New Angular App
Step 2 – Install Search Library
Step 3 – Add Code on App.Module.ts File
Step 4 – Add Code on View File
Step 5 – Add Code On app.Component ts File
Step 6 – Start the Angular App

Step 1 – Create New Angular App

First of all, open your terminal and execute the following command on it to install angular app:

ng new my-new-app

"node_modules/bootstrap/dist/css/bootstrap.min.css"
],
...
...

Once you created a new angular app and entered into the project further, you have to install and add the ng2-search-filter plugin into the angular app:

$ npm i ng2-search-filter --save

Step 3 – Add Code on App.Module.ts File

In this step, visit src/app directory and open app.module.ts file. And then add the following lines of into app.module.ts file:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app';

import { Ng2SearchPipeModule } from 'ng2-search-filter';

@NgModule({
imports: [

<tr *ngFor="let item of filterData | filter:term">
<td>{{item.firstName}}</td>
<td>{{item.lastName}}</td>
<td>{{item.address}}</td>
</tr>
</tbody>
</table>

export class AppComponent {

term: string;

filterData = [
