Utilizing Angular 2 or TypeScript to Retrieve Visitor's Location

I initially began using

ServerVariables["HTTP_CF_IPCOUNTRY"]
on the backend server, but it's proving to be too slow. I'm looking for an Angular or TypeScript alternative to speed things up.

Answer №1

To retrieve the user's location from the front-end, JavaScript can be used effectively.

var userLocation = document.getElementById("demo");
function getLocation() {
        if (navigator.geolocation) {
            navigator.geolocation.getCurrentPosition(showUserPosition);
        } else {
            userLocation.innerHTML = "Geolocation is not supported by this browser.";
        }
    }
    function showUserPosition(position) {
        userLocation.innerHTML = "Latitude: " + position.coords.latitude + 
        "<br>Longitude: " + position.coords.longitude; 
    }

By executing this code, the browser will prompt the user to share their location.

Within an Angular 2 Component that implements the OnInit interface, place the JavaScript inside the ngOnInit function.

import { Component, OnInit } from '@angular/core';
export class LocationComponent implements OnInit {
    ngOnInit(){
        if(window.navigator.geolocation){
            window.navigator.geolocation.getCurrentPosition(this.setUserPosition.bind(this));
        };
    }
}

Successfully resolved the issue by referring to Vivek's demonstration.

ngOnInit() {

    if (window.navigator && window.navigator.geolocation) {
        window.navigator.geolocation.getCurrentPosition(
            position => {
                this.geolocationPosition = position;
                console.log(position);
            },
            error => {
                switch (error.code) {
                    case 1:
                        console.log('Permission Denied');
                        break;
                    case 2:
                        console.log('Position Unavailable');
                        break;
                    case 3:
                        console.log('Timeout');
                        break;
                }
            }
        );
    }
}
