4. Import the `modules`, `Components` and `services`

Import Components in the NgModule of your application as shown below:

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule }   from '@angular/forms';
import { AppComponent }   from './app.component';
import { HttpModule }  from '@angular/http';
import { LocationAutocompleteComponent } from 'ng2-location-autocomplete/index';
@NgModule({
  imports:      [ BrowserModule, FormsModule, HttpModule ],
  declarations: [ AppComponent, LocationAutocompleteComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

5 Use `LocationAutocompleteComponent` in your application

import { Component } from '@angular/core';
import { LocationAutocompleteComponent } from 'ng2-location-autocomplete/index';

@Component({
  selector: 'my-app',
  template: `<h1>My First Angular App</h1>
            <location-autocomplete [name]="'address'" [placeholder]="'Search Location'" classes="field location-field" [offset]="3" (getAddress)="getAddress($event)" [currentLocation]="'true'"> </location-autocomplete>
            `
})
export class AppComponent { 
  getAddress(data) {
    console.log(data);
  }
}

getAddress(data) function will return selected address, or if currentLocation is set to true, It will return current address initially.

6 Use `LocationAutocompleteService` in your application

-To get current location in you Component separately you could use this service separately.

import { Component } from '@angular/core';
import { LocationAutocompleteService } from 'ng2-location-autocomplete/index';

@Component({
  selector: 'my-app',
  template: `<h1>My First Angular App</h1>`
  providers: [LocationAutocompleteService]
})

export class AppComponent implements OnInit{
    private address: any = {
        street_number: '',
        locality: '',
        administrative_area_level_1: '',
        postal_code: '',
        lng: '',
        lat: '',
        formatted_address: ''
    }
    constructor(private _LocationAutocompleteService: LocationAutocompleteService) {}
    ngOnInit(): void {
        var opts: any = {
            enableHighAccuracy: true,
            timeout: "Infinity",
            maximumAge: "Infinity"
        }
        
        this._LocationAutocompleteService.getBrowserLocation(opts)
            .subscribe(
                res => {
                    console.log(res);
                    this._LocationAutocompleteService.getLocation(res)
                        .subscribe(
                            data => {
                                console.log(data)
                                this.responseData = data;
                                this.address = this.responseData.formatted_address;
                                this.getAddress.next(this.responseData);
                            }
                        )
                }
            )
    }
