Building a Current Location Fetching Application in Ionic (GPS Tracking)

Building a Current Location Fetching  Application in Ionic (GPS Tracking) 

Prerequisites:

  1. Node.js: Make sure Node.js is installed on your system. You can download and install it from the official website.
  2. Ionic CLI: Install the Ionic CLI globally on your system by running the following command in your terminal or command prompt:

    npm install -g @ionic/cli


  3. IDE: Choose a code editor or an Integrated Development Environment (IDE) of your preference. Popular choices include Visual Studio Code, Atom, or Sublime Text.

Step 1: Create a New Ionic Project

Open your terminal or command prompt and navigate to the directory where you want to create your Ionic project. Then, run the following command to create a new Ionic project:

ionic start locationApp blank --type=angular

Step 2: Add Required Plugins

Ionic provides plugins to access device features like geolocation. Install the Cordova Geolocation plugin by running the following command inside your project directory:



ionic cordova plugin add cordova-plugin-geolocation
npm install @ionic-native/geolocation


Step 3: Implement Location Fetching

Open your project in your chosen code editor and navigate to the home.page.ts file located in the src/app/home directory. This is where we'll implement the logic to fetch the user's current location.



import { Component } from '@angular/core';
import { Geolocation } from '@ionic-native/geolocation/ngx';

@Component({
selector: 'app-home',
templateUrl: 'home.page.html',
styleUrls: ['home.page.scss'],
})
export class HomePage {

constructor(private geolocation: Geolocation) {}

getLocation() {
this.geolocation.getCurrentPosition().then((resp) => {
// resp.coords.latitude
// resp.coords.longitude
alert("Latitude: " + resp.coords.latitude + "\nLongitude: " + resp.coords.longitude);
}).catch((error) => {
console.log('Error getting location', error);
});
}

}

Step 4: Display Location Data

Open the home.page.html file in the same directory and add a button to trigger the location fetching process.


<ion-header>
<ion-toolbar>
<ion-title>
Location App
</ion-title>
</ion-toolbar>
</ion-header>

<ion-content>
<ion-button (click)="getLocation()">Get Current Location</ion-button>
</ion-content>

Step 5: Run Your App

Save all your changes and return to your terminal or command prompt. Navigate to your project directory and run the following command to launch your Ionic app in a browser:

ionic serve

ionic serve

Congratulations! You've successfully built a current location fetching application using Ionic. Users can now click the button to retrieve their current location, enabling you to develop a wide range of location-based features and services.

Feel free to explore further enhancements, such as displaying the fetched location on a map or integrating additional functionalities based on the user's location data. Happy coding!

Troubleshooting AWS ACM Certificate Status Failed Error

Introduction: Amazon Web Services (AWS) provides the Amazon Certificate Manager (ACM) service for managing SSL/TLS certificates for your websites and applications. However, sometimes you may encounter issues where the certificate status shows as "Failed". One common reason for this failure is related to Certificate Authority Authorization (CAA) records. In this blog post, we will discuss how to troubleshoot the AWS ACM certificate status failed error and resolve it by adjusting the CAA records. Understanding the Issue: When an ACM certificate status shows as "Failed", it indicates that the certificate request failed validation checks. One of the potential causes for this failure is related to CAA records. CAA records are DNS resource records that specify which certificate authorities (CAs) are authorized to issue certificates for a domain. If your domain's CAA records restrict certificate issuance to specific CAs, and AWS ACM is not listed as an authorized CA, t...
