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!

Adding Debounce to Search Bar in Ionic: A Step-by-Step Guide

  Introduction: In Ionic applications, implementing a search functionality is a common requirement. However, performing a search operation with every keystroke can be resource-intensive and may lead to performance issues, especially in large datasets. To optimize this, we can introduce a debounce mechanism, which triggers the search function only after a certain period of inactivity. In this step-by-step guide, we'll learn how to add debounce to a search bar in an Ionic application. Prerequisites: Basic understanding of Ionic framework. Ionic CLI installed. A basic Ionic project set up. Step 1: Create an Ionic Project If you haven't already set up an Ionic project, create one using the Ionic CLI with the following command: ionic start myApp blank Step 2: Add a Search Bar Component In your Ionic project, navigate to the page or component where you want to add the search functionality. Replace the existing code with the following snippet: < ion - col size = "12...
