Introducing Shopify App and Laravel

Laravel is a strong PHP framework that simplifies web development, making it more enjoyable and efficient for developers. Taylor Otwell introduced it in 2011, and it is rapidly becoming popular due to its sturdy features and modern look.

Laravel is a favorite among developers due to its comprehensive toolset and features that simplify development. With extensive documentation, an active community, and regular updates, Laravel ensures developers have the support and resources to build robust, scalable web applications.

A Shopify app is an extension or add-on that integrates with Shopify stores, providing additional functionalities and extending the platform’s capabilities. It may be used for various purposes, such as product management, order management, customer engagement, analytics and reporting, etc.

Types of Shopify Apps

Shopify apps come in various types, each serving different purposes and catering to different needs. Here are the main types of Shopify apps:

1. Public Apps: These apps are available to all Shopify store owners through the Shopify App Store. Public apps are designed to address common needs and provide general functionality that can benefit a wide range of stores. They are further categorized into:

• Listed Apps: These apps are visible in the Shopify App Store and can be found through search and category listings.

• Unlisted Apps: These apps are not displayed in the Shopify App Store search results or categories. They can be installed via a direct link provided by the developer.

2. Custom Apps: Custom apps are specifically built for individual Shopify stores to meet unique requirements that public apps cannot fulfill. These applications are not available on the Shopify App Store but are ideal for businesses with specific needs. Custom apps can be created by the store owner or a developer and installed directly in the store.

3. Draft Apps: These apps are in the development stage and are used by Shopify Partners during the app creation process. Draft apps allow developers to test and refine features before the app is fully released.

How to Create a Shopify App Using Laravel

Step 1: Install Laravel: Create a new Laravel app project with this command line below:

composer require osiset/laravel-shopify
php artisan vendor:publish --tag=shopify-config

Step 2: Create Authentication Routes: Open routes/web.php and create a route to handle your new app’s homepage.

Route::get('/', 'ShopifyAppController@index');

Step 3: Create a Controller: Generate a controller to handle the logic for installation and authentication:

php artisan make:controller ShopifyController

In app/Http/Controllers/ShopifyController.php, add methods for index:

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class ShopifyAppController extends Controller
{
    public function index(Request $request)
    {
        // Add your Shopify API logic here
        return view('shopify.index');
    }
}

Step 4: Create a Blade View:

Create a view file to display products.

Create a directory resources/views/shopify along with a file named index.blade.php.

<!DOCTYPE html>
<html>
<head>
    <title>Shopify App</title>
</head>
<body>
    <h1>Shopify Products</h1>
    <ul>
        @foreach ($products as $product)
            <li></li>
        @endforeach
    </ul>
</body>
</html>

Step 5: Install Required Packages:

Install Guzzle HTTP client in order to create requests to Shopify’s API with this command:

composer require guzzlehttp/guzzle

Step 6: Add Shopify API Logic:

After you requested Shopify’s API in step 5, it’s time to add the logic to fetch your products using Shopify API. You’ll need to do this step in the ShopifyAppController.

public function index(Request $request)
{
    // Replace with your Shopify store credentials
    $shopifyStore = 'your-shopify-store.myshopify.com';
    $apiKey = 'your-api-key';
    $apiPassword = 'your-api-password';
    // Make a request to Shopify's API to get products
    $client = new \GuzzleHttp\Client();
    $response = $client->get("https://$shopifyStore/admin/api/2021-07/products.json", [
        'auth' => [$apiKey, $apiPassword]
    ]);
    $products = json_decode($response->getBody(), true)['products'];
    return view('shopify.index', compact('products'));
}

Step 7: Create a New App in Shopify: Navigate to Shopify Partner dashboard and create a new app. Provide the API key and password.

Step 8: Testing and Deployment:

Start your Laravel server:

php artisan serve

Install Your App on Shopify to check if it works properly

Handling Errors and Exceptions in Laravel-Shopify Integration

When integrating Laravel with Shopify, efficiently managing errors and exceptions is essential to provide a pleasant user experience and the reliability of your application. Here’s how you can manage errors and exceptions in your Laravel-Shopify integration:

Common Errors: When integrating Laravel with Shopify, developers may encounter several common errors. These can include issues with API authentication, incorrect API endpoints, rate limiting, and data validation errors. Understanding these common pitfalls can help in diagnosing and resolving issues more efficiently.

Laravel’s Built-In Exception Handling: Laravel comes with a strong system for managing errors and exceptions. Whenever an exception is thrown during your application’s runtime, Laravel automatically catches and handles it. You can adjust how these exceptions are logged and shown to users by modifying the App\Exceptions\Handler class.

Logging: Always log errors & exceptions using Laravel’s built-in logging system. Store error messages in log files, and configure the logging channels and levels in the config/logging.php file.

API Error Handling: The Shopify API communicates errors through response codes and JSON structures. Parse API responses and check for error codes. Extract error messages and relevant details to inform appropriate user feedback or logging.

HTTP Status Codes: Check the response status code. For successful requests, the status code will typically be in the 200 range. For errors, you might encounter codes like 400 (Bad Request), 401 (Unauthorized), 404 (Not Found), or 500 (Internal Server Error).

use Illuminate\Support\Facades\Http;

try {
    $response = Http::get('https://shopify-api-url.com');
    $response->throw();
} catch (\Exception $e) {
    // Handle HTTP errors here
}

Retry Logic: Consider implementing retry logic for transient errors (e.g., network issues). However, avoid excessive retries to prevent infinite loops.

Testing Error Handling: To ensure your error-handling mechanisms are functioning correctly, write unit tests and integration tests. Laravel’s testing framework offers tools to simulate exceptions and errors during testing.

Watch Out for Shopify Rate Limits: Keep Shopify’s rate-limiting rules in mind. If you send too many requests in a short period, Shopify might limit your rate. Handle this by checking the response headers for the retry-after time and pausing your requests until then.

Custom Middleware for Exception Handling: You can create your own middleware in Laravel to manage specific exceptions or errors in a unique way. This is useful if you want to redirect users to different error pages or handle errors in a particular manner.

Monitoring and Warning: To be informed when there are serious problems with your Shopify connection, set up alerting and monitoring systems. This is when tools like Sentry, Laravel Horizon, and bespoke solutions come in handy.
