🔥 lazy() processes millions of records without killing your server!

Enhance Web Application Performance with JavaScript Debouncing

Ghanshyam Kumar — Mon, 09 Oct 2023 06:00:46 +0000

Debouncing

Debouncing is a programming technique that plays a vital role in optimizing web applications by controlling the frequency of function calls. In this article, we'll explore the essence of debouncing, grasp its significance, and master its implementation in JavaScript through practical code examples.

Demystifying Debouncing

Debouncing is akin to a skilled conductor, orchestrating the execution of a function only after a specific duration has passed since the last invocation. Its importance shines in situations where you seek to avert redundant, costly, or resource-hungry function calls.

Why Debouncing Matters

Picture a scenario where a live search bar eagerly suggests results as users type. Without debouncing, each keystroke triggers a flurry of function calls, potentially overwhelming servers and causing sluggish user experiences. Debouncing steps in to pause and patiently wait for a moment of tranquility in the user's typing before initiating any requests.

Implementing Debouncing in JavaScript

While there are various ways to implement debouncing in JavaScript, a common practice involves employing a wrapper function. This wrapper returns a new function that defers the execution of the original function. Additionally, it manages a timer variable, skillfully resetting or clearing the delay whenever the new function is summoned. The code snippet below demonstrates this technique:

const debounce = (mainFunction, delay) => {
  let timer;

  return function (...args) {
    clearTimeout(timer);

    timer = setTimeout(() => {
      mainFunction(...args);
    }, delay);
  };
};

Practical Application of Debouncing

Let's put debouncing to practical use using an HTML input field:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
</head>
<body>
   Search :  <input type="text" onkeyup="search()" id="word"><br>
   <h6 id="result"> Search Data is : </h6>

   <script>

    function debounce(func, delay) {
        let timeId;
        return function () {
            clearTimeout(timeId);
            timeId = setTimeout(func, delay);
        }
    }

    function debounceSearch() {
        let inputData = document.getElementById("word").value;
        let inputResult = document.getElementById("result");

        inputResult.innerHTML = `Searching for: "${inputData}"`;
    }

    const search = debounce(debounceSearch, 1000);

   </script>
</body>
</html>

In this example, we have an HTML input field (word) where users can enter search queries. As they type, the onkeyup event invokes the search function, which in turn applies debouncing to the debounceSearch function. This ensures that the search function activates only after a brief pause in typing.

Debouncing in Real-Life Scenarios

Debouncing finds its relevance in real-life scenarios, where it contributes to efficiency and user-friendliness:

Submit Button: Consider a website's submit button. It abstains from sending data immediately and waits briefly to ascertain if another click is forthcoming. This preventive measure thwarts accidental double submissions and mitigates potential errors.
Elevator Button: When you press an elevator button, it doesn't leap into motion instantaneously. Instead, it gracefully waits a few moments to accommodate other passengers' requests, optimizing energy consumption and travel time.
Search Box: In a search box, you'll notice suggestions don't flood in with every keystroke. They pause and wait until you've momentarily ceased typing. This strategic delay sidesteps overwhelming server requests and improves overall system performance.

In Conclusion

Debouncing, a powerful technique, streamlines web applications by curbing redundant function calls, safeguarding performance, and enhancing user experiences. In JavaScript, mastering debouncing is a matter of implementing a wrapper function that defers execution until an appropriate time, preserving efficiency while accommodating user interactions.

This article has provided you with a comprehensive understanding of debouncing in JavaScript, along with practical insights for its implementation. Feel free to explore further and apply this valuable technique to optimize your web development projects.

Stripe Payment in Laravel 10

Ghanshyam Kumar — Wed, 02 Aug 2023 05:22:49 +0000

Stripe Payment Integration

Stripe is a popular payment processing platform that allows businesses to accept online payments seamlessly. In this tutorial, we will guide you through the process of integrating Stripe payment into a Laravel web application. By the end of this guide, you will be able to accept payments from your users using Stripe's secure and efficient payment system.

Prerequisites

Before we start, make sure you have the following prerequisites:

Basic understanding of Laravel and web development.
A Stripe account to obtain the necessary API keys. If you don't have one, you can sign up for free at Stripe's official website.

Part 1: Setting up the Laravel Project

First, let's set up a new Laravel project or use an existing one. If you're starting from scratch, you can create a new Laravel project using the following command:

composer create-project --prefer-dist laravel/laravel stripe-payment
cd stripe-payment

Next, we need to install the required packages for Stripe integration. Open the terminal and run the following command:

composer require stripe/stripe-php

Once the packages are installed, you'll need to set up your environment variables. In the root of your Laravel project, create a .env file and add the following lines:

STRIPE_KEY=your_stripe_publishable_key
STRIPE_SECRET=your_stripe_secret_key

Replace your_stripe_publishable_key and your_stripe_secret_key with your actual Stripe API keys.

Part 2: Creating the Stripe.blade.php View

Now, let's create the view for our payment form. In your resources/views directory, create a new file named stripe.blade.php and add the following code:

<!DOCTYPE html>
<html>
<head>
    <title>Card Payment</title>
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/3.3.7/css/bootstrap.min.css" />
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>

<div class="container">
    <h1>Stripe Payment from your card</h1>

    <div class="row">
        <div class="col-md-6 col-md-offset-3">
            <div class="panel panel-default credit-card-box">
                <div class="panel-heading display-table" >
                    <h2 class="panel-title">Checkout Forms</h2>
                </div>
                <div class="panel-body">
                    @if (Session::has('success'))
                        <div class="alert alert-success text-center">
                            <a href="#" class="close" data-dismiss="alert" aria-label="close">×</a>
                            <p>{{ Session::get('success') }}</p>
                        </div>
                    @endif

                    <form id='checkout-form' method='post' action="{{ route('stripe.post') }}">   
                        @csrf             
                        <input type='hidden' name='stripeToken' id='stripe-token-id'>                              
                        <br>
                        <div id="card-element" class="form-control"></div>
                        <button 
                            id='pay-btn'
                            class="btn btn-success mt-3"
                            type="button"
                            style="margin-top: 20px; width: 100%;padding: 7px;"
                            onclick="createToken()">PAY $10
                        </button>
                    </form>
                </div>
            </div>        
        </div>
    </div>
</div>
</body>

<script src="https://js.stripe.com/v3/"></script>
<script type="text/javascript">
    var stripe = Stripe('{{ env('STRIPE_KEY') }}')
    var elements = stripe.elements();
    var cardElement = elements.create('card');
    cardElement.mount('#card-element');

    /*------------------------------------------
    --------------------------------------------
    Create Token Code
    --------------------------------------------
    --------------------------------------------*/
    function createToken() {
        document.getElementById("pay-btn").disabled = true;
        stripe.createToken(cardElement).then(function(result) {

            if (typeof result.error != 'undefined') {
                document.getElementById("pay-btn").disabled = false;
                alert(result.error.message);
            }

            /* creating token success */
            if (typeof result.token != 'undefined') {
                document.getElementById("stripe-token-id").value = result.token.id;
                document.getElementById('checkout-form').submit();
            }
        });
    }
</script>
</html>

Part 3: The web.php Routes

In the routes/web.php file, add the following routes to handle the payment:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\StripePaymentController;

Route::get('/', function () {
    return view('welcome');
});

Route::get('/stripe', [StripePaymentController::class, 'stripe']);
Route::post('/stripe', [StripePaymentController::class, 'stripePost'])->name('stripe.post');

Part 4: The StripePaymentController.php Controller

Next, let's create the controller to handle the payment logic. In the app/Http/Controllers directory, create a new file named StripePaymentController.php and add the following code:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Stripe;
use Illuminate\View\View;
use Illuminate\Http\RedirectResponse;

class StripePaymentController extends Controller
{
    /**
     * success response method.
     *
     * @return \Illuminate\Http\Response
     */
    public function stripe(): View
    {
        return view('stripe');
    }

    /**
     * success response method.
     *
     * @return \Illuminate\Http\Response
     */
    public function stripePost(Request $request): RedirectResponse
    {
        Stripe\Stripe::setApiKey(env('STRIPE_SECRET'));

        Stripe\Charge::create([
            "amount" => 100 * 100,
            "currency" => "usd",
            "source" => $request->stripeToken,
            "description" => "Test payment from your card"
        ]);

        return back()
            ->with('success', 'Payment successful!');
    }
}

Part 5: Making a Test Payment

Now comes the exciting part - testing the payment integration. To simulate a payment, you can use the following test card details provided by Stripe:

Card Number: 4242 4242 4242 4242
Expiry Date (MM/YY): 04/25
CVC: 005
ZIP: 55555

Please note that these are test card details meant for demonstration purposes only. In a real production environment, you would need to use valid card information.

Here's how you can test the payment:

Open the application in your web browser and navigate to the payment page.
Enter the test card details provided above into the payment form.
Click the "PAY $10" button to initiate the payment.
If the payment is successful, you should see a success message indicating that the payment was successful.
You can also check your Stripe Dashboard to see

the details of the test payment.

Remember that as we are using the test card details, no real money will be charged, and the transaction will not affect your actual Stripe account balance.

Conclusion

Congratulations! You have successfully integrated Stripe payment into your Laravel web application. You can now securely accept payments from your users using Stripe's robust and reliable payment system. This integration opens up numerous opportunities for monetizing your application and enhancing the user experience.
