Angular 5 autocomplete geolocation npm install not working - google-maps-api-3

Question

In my Angular 5 project I want to implement google autocomplete geolocation.
I got some reference of npm modules:-
https://www.npmjs.com/package/ng4-geoautocomplete
https://www.npmjs.com/package/ngx-google-places-autocomplete
According to their guidance when I am going to install that module I am facing some warning:
Installation command:-
npm install --save ng4-geoautocomplete
Warnings:-

Why I am facing this problem and what will be the solution?
Is there any other way to implement google autocomplete geolocation?

Answer 1

Yes.
npm install #agm/core --save-dev
npm install #types/googlemaps --save-dev
app.module.ts
import {AgmCoreModule} from '#agm/core'
.
.
.
imports: [
.
.
.
AgmCoreModule.forRoot({
apiKey: 'your api key',
libraries: ['places']
}),
.
.
.
]
in your html
<div>
<input type="text" placeholder="Search for location" autocorrect="off" name="" spellcheck="off" #autoSearch/>
</div>
component.ts file
import {Component, ViewChild, ElementRef, NgZone, OnInit} from '#angular/core'
import { MapsAPILoader } from '#agm/core';
import {} from #types/googlepmaps;
.
.
.
export class YourComponent implements OnInit {
#ViewChild('autoSearch') public searchElement: ElementRef;
consturctor (private mapsAPILoader: MapsAPILoader , private ngZone : NgZone )
{}
ngOnInit() {
this.mapsAPILoader.load().then(
() => {
let autocomplete = new
google.maps.places.Autocomplete(this.searchElement.nativeElement,
{types:["address"]});
autocomplete.addListener("place_changed", ()=> {
this.ngZone.run(()=>{
let place: google.maps.places.PlaceResult =
autocomplete.getPlace();
if(place.geometry === undefined || place.geometry === null) {
return;
}
})
})
}
);
}
}
I rather use the AGM library rather than just the autocomplete that you are using because the autocomplete only gives you autcomplete fucntionalty whether the AGM can be use to render the google maps with the markers.
Now,
to install dependencies yourself to fix your warnings you can reference to this stackoverflow question: How to install npm peer dependencies automatically?
