How can I add my current location to Firebase? - ionic-framework

Question

In my Ionic 2 application, I'm able to see my current location on the map, but how can I add the location (longtitude and latitude) to Firebase?
initMap(): Promise<any> {
this.mapInitialised = true;
return new Promise((resolve) => {
Geolocation.getCurrentPosition().then((position) => {
let latLng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
//let latLng = new google.maps.LatLng(40.713744, -74.009056);
let mapOptions = {
center: latLng,
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
this.map = new google.maps.Map(this.mapElement, mapOptions);
resolve(true);
google.maps.event.addListener(this.map, 'click', (event) => {
this.clearMarkers();
let geocoder = new google.maps.Geocoder;
let infowindow = new google.maps.InfoWindow;
let distanceToYou = this.getDistanceBetweenPoints(
event.latLng,
position,
'miles'
).toFixed(2);
this.geocodeLatLng(event.latLng,geocoder,infowindow,distanceToYou);
});
});
});
}
I'm able to get the current position of me and if I double click the map I can see the distance between me and the marker.

Yes it's possible. But since double clicking a map zooms it, i'll use press. But it would be better if you set a button on a info window with a "save location" text or something like this to call the saving function.
YOUR HTML
<div #mapID (press)="saveLocation()">
YOUR .TS
import * as firebase from 'firebase';
public lat;
public long;
initMap(): Promise<any> {
this.mapInitialised = true;
return new Promise((resolve) => {
Geolocation.getCurrentPosition().then((position) => {
this.lat = position.coords.latitude;
this.long = position.coords.longitude;
// YOUR CODE CONTINUES HERE...
});
});
});
saveLocation(){
firebase.database().ref('PATH/YOU/WANT/TO/SAVE').update({
lat: this.lat,
long: this.long
}).then(res =>{
// THE LOCATION IS SAVED, DO YOUR STUFF
})
}
Like this you can save you location, use update() instead of set() so you don't subscribe other data.
If you want to retrieve that data just use firebase.database().ref('PATH/YOU'VE/SAVED').once('value', snapshot =>{ // CODE });
Hope it helps
