Angular 16 Autocomplete Input using Material ui Tutorial

Steps to implement autocomplete input search using material ui library in angular 16 apps:

  • Step 1 – Create New Angular 16 App
  • Step 2 – Install Material Package
  • Step 3 – Import Modules in Module.ts File
  • Step 4 – Create Autocomplete Input Search on View File
  • Step 5 – Add Code On Component ts File
  • Step 6 – Create Services
  • Step 7 – Start Angular App

Step 1 – Create New Angular 16 App

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

ng new my-new-app

Step 2 – Install Material Package

Once you have installed the angular app into your system. Next, you need to run the following command on terminal or cmd to install angular material:

ng add @angular/material

Step 3 – Import Modules in Module.ts File

Once you have installed angular material, you need to import material in module.ts. So visit src/app directory and open app.module.ts file. Then add the following code into it:


import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import {FormsModule, ReactiveFormsModule} from '@angular/forms';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatFormFieldModule } from '@angular/material/form-field';
import { MatInputModule } from '@angular/material/input';
import {MatAutocompleteModule} from '@angular/material/autocomplete';
import { HttpClientModule } from '@angular/common/http';
  declarations: [
  imports:      [
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }

Step 4 – Create Autocomplete Input Search on View File

Now, you need to create simple reactive form to get input values of autocomplete search. So, visit src/app/app.component.html and update the following code into it:

<h1>Angular 16 material input autocomplete with API example - Tutsmake.Com</h1>
<form class="example-form">
               placeholder="Enter Location" 
        <mat-autocomplete #auto="matAutocomplete">
                *ngFor="let option of filteredOptions | async" 

Step 5 – Add Code On Component ts File

Next, you need to visit the src/app directory and open app.component.ts. Then add the following code into component.ts file:


import { Component } from '@angular/core';
import {Observable} from 'rxjs';
import { startWith, debounceTime, distinctUntilChanged, switchMap, map } from 'rxjs/operators';
import {FormControl} from '@angular/forms';
import { PostService } from './post.service';
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent {
  myControl = new FormControl();
  options = [];
  filteredOptions: Observable;

  constructor(private service: PostService) {
     this.filteredOptions = this.myControl.valueChanges.pipe(
      switchMap(val => {
            return this.filter(val || '')
  filter(val: string): Observable {

    return this.service.getData()
       map(response => response.filter(option => { 
         return === 0

Step 6 – Create Service

Next, you need to create a service for material autocomplete. So visit the src/app/ directory and open or create post.service.ts. Then add the following code to post.service.ts file:

import { Injectable } from '@angular/core';

import { HttpClient } from '@angular/common/http';

import { tap, map } from 'rxjs/operators';

import { of } from 'rxjs';



  providedIn: 'root'


export class PostService {


  constructor(private http: HttpClient) { }


    opts = [];


    getData() {


          return this.opts.length ?

            of(this.opts) :

            this.http.get('').pipe(tap(data => this.opts = data))




Step 7 – Start Angular App

Finally, run the following commands on terminal or cmd to start angular app:

ng serve

Open your browser and navigate to http://localhost:4200 to see your autocomplete component in action.


Congratulations you have learned how to create an autocomplete input search in angular 16 apps using angular material.
