npm install --save ngx-google-maps-places-api ngx-google-maps-places-autocomplete
Follow these steps to get an API key that can be used to load Google Maps.
Include the Dynamic Library Import script in the index.html of your app. When a Google Map is being rendered, it'll use the Dynamic Import API to load the necessary JavaScript automatically.
<!-- index.html -->
<!DOCTYPE html>
<body>
...
<script>
(g=>{var h,a,k,p="The Google Maps JavaScript API",c="google",l="importLibrary",q="__ib__",m=document,b=window;b=b[c]||(b[c]={});var d=b.maps||(b.maps={}),r=new Set,e=new URLSearchParams,u=()=>h||(h=new Promise(async(f,n)=>{await (a=m.createElement("script"));e.set("libraries",[...r]+"");for(k in g)e.set(k.replace(/[A-Z]/g,t=>"_"+t[0].toLowerCase()),g[k]);e.set("callback",c+".maps."+q);a.src=`https://maps.${c}apis.com/maps/api/js?`+e;d[q]=f;a.onerror=()=>h=n(Error(p+" could not load."));a.nonce=m.querySelector("script[nonce]")?.nonce||"";m.head.append(a)}));d[l]?console.warn(p+" only loads once. Ignoring:",g):d[l]=(f,...n)=>r.add(f)&&u().then(()=>d[l](f,...n))})({
v: "weekly",
key: YOUR_API_KEY_GOES_HERE
});
</script>
</body>
</html>
Note: the component also supports loading the API using the legacy script tag, however it isn't recommended because it requires all of the Google Maps JavaScript to be loaded up-front, even if it isn't used.
Import the NgxGoogleMapsPlacesAutocompleteModule in your Angular module:
import { NgModule } from '@angular/core';
import { NgxGoogleMapsPlacesAutocompleteModule } from 'ngx-google-maps-places-autocomplete';
@NgModule({
imports: [
NgxGoogleMapsPlacesAutocompleteModule,
// ... other imports
],
// ... declarations, providers, etc.
})
export class AppModule { }
Or, directly import the NgxGoogleMapsPlacesAutocompleteDirective in your Angular standalone component/directive:
import { ChangeDetectionStrategy, Component } from '@angular/core';
import { NgxGoogleMapsPlacesAutocompleteDirective } from 'ngx-google-maps-places-autocomplete';
@Component({
changeDetection: ChangeDetectionStrategy.OnPush,
selector: 'app-root',
standalone: true,
imports: [
NgxGoogleMapsPlacesAutocompleteDirective
],
templateUrl: './app.component.html',
styleUrl: './app.component.scss'
})
export class AppComponent { }
Use the ngxGoogleMapsPlacesAutocomplete directive within an matAutocomplete input element:
<mat-form-field>
<mat-label>Address</mat-label>
<input type="text"
placeholder="Pick your address"
aria-label="Address"
matInput
formControlName="address"
[matAutocomplete]="addressAutocomplete"
ngxGoogleMapsPlacesAutocomplete
#placesAutocomplete="ngxGoogleMapsPlacesAutocomplete" />
<!--
In addition to ngxGoogleMapsPlacesAutocomplete above you can use the following inputs/outputs like:
[shouldLoadPlaceDetails]="true"
[fetchFields]="[ 'addressComponents', 'location', 'googleMapsURI' ]"
[placesAutocompleteRequest]="{ includedRegionCodes: [ 'UA' ] }"
[placesAutocompleteDebounceTime]="575"
(optionsLoad)="onSuggestionsLoaded($event)"
(placeDetailsLoad)="onPlaceDetailsLoaded($event)"
-->
<mat-autocomplete autoActiveFirstOption #addressAutocomplete="matAutocomplete">
@for (option of placesAutocomplete.options$(); track option.prediction.placeId) {
<mat-option [value]="option">
<div matLine class="text-main" [innerHtml]="option.formattedMainHtml"></div>
<small matLine class="text-secondary" [innerHtml]="option.formattedSecondaryHtml">
</small>
</mat-option>
}
</mat-autocomplete>
