Dependencies

  • Angular (requires Angular latest | we are using already v16 ;)

optional

npm i -D @types/googlemaps 

1. Install via ng add. (Recommended)

If Angular Material Design is not setup, just run ng add @angular/material learn more

Now add the library via the angular schematics and everything will be setup for you

ng add @angular-material-extensions/google-maps-autocomplete

2. Install via npm. (Alternative)

Now install @angular-material-extensions/google-maps-autocomplete via:

npm install --save @angular-material-extensions/google-maps-autocomplete

Requirements (peer dependencies):

for the ui input component, please consider installing the following packages

ng add @angular/material  

Additional requirements Theme (Material Design)


Once installed you need to import the main module:

import {MatGoogleMapsAutocompleteModule} from '@angular-material-extensions/google-maps-autocomplete';

The only remaining part is to list the imported module in your application module. The exact method will be slightly different for the root (top-level) module for which you should end up with the code similar to ( notice MatGoogleMapsAutocompleteModule.forRoot()):

import {MatGoogleMapsAutocompleteModule} from '@angular-material-extensions/google-maps-autocomplete';

@NgModule({
  declarations: [AppComponent, ...],
  imports: [
    MatGoogleMapsAutocompleteModule.forRoot('YOUR_GOOGLE_MAPS_API_KEY'), ...],
  bootstrap: [AppComponent]
})
export class AppModule {
}

Other modules in your application can simply import MatGoogleMapsAutocompleteModule:

import {MatGoogleMapsAutocompleteModule} from '@angular-material-extensions/google-maps-autocomplete';

@NgModule({
  declarations: [OtherComponent, ...],
  imports: [
    MatGoogleMapsAutocompleteModule, ...],
})
export class OtherModule {
}

As directive

add matGoogleMapsAutocomplete to your target html input element to enable the google maps autocomplete api as feature

<mat-form-field>
  <mat-label>Address << using the directive >></mat-label>
  <input matInput
         matGoogleMapsAutocomplete
         [country]="de"
         (onAutocompleteSelected)="onAutocompleteSelected($event)"
         (onLocationSelected)="onLocationSelected($event)">
</mat-form-field>

As components

or alternatively use mat-google-maps-auto-complete, the UI wrapper

add mat-google-maps-auto-complete element to your template

mat-google-maps-auto-complete

<mat-google-maps-autocomplete [appearance]="appearance.OUTLINE"
                              (onAutocompleteSelected)="onAutocompleteSelected($event)"
                              (onLocationSelected)="onLocationSelected($event)">
</mat-google-maps-autocomplete>

A customized mat-google-maps-autocomplete

<mat-google-maps-autocomplete country="us"
                              type="address"
                              (onAutocompleteSelected)="onAutocompleteSelected($event)"
                              (onLocationSelected)="onLocationSelected($event)">
</mat-google-maps-autocomplete>

combine the result of the mat-google-maps-autocomplete with a google map instance

<div class="container" fxLayout="column" fxLayoutAlign="center">

  <div fxFlex fxFlexAlign="center"
       class="autocomplete-container"
       [ngStyle.xs]="{'min-width.%': 100}"
       [ngStyle.sm]="{'width.%': 70}">
    <mat-google-maps-autocomplete (onAutocompleteSelected)="onAutocompleteSelected($event)"
                                  (onLocationSelected)="onLocationSelected($event)"
                                  (onGermanAddressMapped)="onGermanAddressMapped($event)">
    </mat-google-maps-autocomplete>
  </div>

</div>

in your component, the code will be similar to -->

import {Component, OnInit, ViewEncapsulation} from '@angular/core';
import {Title} from '@angular/platform-browser';
import {Location, Appearance, GermanAddress} from '@angular-material-extensions/google-maps-autocomplete';
import {} from '@types/googlemaps';
import PlaceResult = google.maps.places.PlaceResult;

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.scss'],
  encapsulation: ViewEncapsulation.None,
})
export class HomeComponent implements OnInit {

  public appearance = Appearance;
  public zoom: number;
  public latitude: number;
  public longitude: number;
  public selectedAddress: PlaceResult;

  constructor(private titleService: Title) {
  }

  ngOnInit() {
    this.titleService.setTitle('Home | @angular-material-extensions/google-maps-autocomplete');

    this.zoom = 10;
    this.latitude = 52.520008;
    this.longitude = 13.404954;

    this.setCurrentPosition();

  }

  private setCurrentPosition() {
    if ('geolocation' in navigator) {
      navigator.geolocation.getCurrentPosition((position) => {
        this.latitude = position.coords.latitude;
        this.longitude = position.coords.longitude;
        this.zoom = 12;
      });
    }
  }

  onAutocompleteSelected(result: PlaceResult) {
    console.log('onAutocompleteSelected: ', result);
  }

  onLocationSelected(location: Location) {
    console.log('onLocationSelected: ', location);
    this.latitude = location.latitude;
    this.longitude = location.longitude;
  }

  onGermanAddressMapped($event: GermanAddress) {
    console.log('onGermanAddressMapped', $event);
  }

}

Reactive Forms Example

<form [formGroup]="addressFormGroup">
  <mat-search-google-maps-autocomplete formControlName="address">
  </mat-search-google-maps-autocomplete>

  // OR

  <mat-google-maps-autocomplete formControlName="address">
  </mat-google-maps-autocomplete>

</form>
import {Component, OnInit} from '@angular/core';
import {FormControl, FormGroup} from '@angular/forms';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {

  addressFormGroup: FormGroup;

  ngOnInit(): void {
    this.addressFormGroup = new FormGroup({
      address: new FormControl(),
    });

    this.addressFormGroup.get('address').valueChanges.subscribe(value => console.log('value changed', value))
  }
}

API - for more info please visit the official documentation Maps JavaScript API

matGoogleMapsAutocomplete

option bind type default description
value Input() PlaceResult ; -
address Input() PlaceResult string; -
country Input() string string[]; -
placeIdOnly Input() boolean - can be used to instruct the Autocomplete widget to retrieve only Place IDs. On calling getPlace() on the Autocomplete object, the PlaceResult made available will only have the place id, types and name properties set. You can use the returned place ID with calls to the Places, Geocoding, Directions or Distance Matrix services.
strictBounds Input() boolean - is a boolean specifying whether the API must return only those places that are strictly within the region defined by the given bounds. The API does not return results outside this region even if they match the user input.
types Input() string[] - An array of types specifies an explicit type or a type collection, as listed in the supported types below. If nothing is specified, all types are returned. In general only a single type is allowed. The exception is that you can safely mix the geocode and establishment types, but note that this will have the same effect as specifying no types. Supported types are listed below.
type Input() string -
autoCompleteOptions Input() AutocompleteOptions - all above inputs in one object! The passed data to this object will be merged with the input if they exists
onChange Output() PlaceResult string null
onAutocompleteSelected Output() PlaceResult - the event will be fired when a place has been selected via the google maps autocomplete component
onGermanAddressMapped Output() GermanAddress - the event will be fired when a place has been selected and mapped to the german address interface
onLocationSelected Output() Location - the event will be fired when a place has been selected via the google maps autocomplete component

Supported Types

type description
geocode instructs the Places service to return only geocoding results, rather than business results.
