How to build eCommerce website using Laravel

In the ever-expanding digital marketplace, having a well-built eCommerce website is crucial for businesses of all sizes. Laravel, an open-source PHP framework, has gained immense popularity for its elegant syntax, powerful tools, and scalability, making it an excellent choice for developing eCommerce websites. This blog will provide a detailed, step-by-step guide on how to build an eCommerce website using Laravel, covering everything from setting up the environment to implementing advanced features like product management, shopping cart functionality, and payment gateways.

Why Choose Laravel for eCommerce Development?

Before diving into the technical details, it’s essential to understand why Laravel is such a compelling choice for eCommerce development:

a. MVC Architecture

Laravel follows the Model-View-Controller (MVC) architectural pattern, which allows developers to separate the business logic from the user interface, making the code more organized, scalable, and maintainable.

b. Built-in Authentication and Authorization

Laravel provides built-in tools for user authentication and authorization, simplifying the process of adding user login and registration features, which are essential for any eCommerce platform.

c. Artisan Command Line Interface

Laravel’s Artisan CLI offers a range of helpful commands for database migrations, testing, seeding, and more, streamlining the development process.

d. Blade Templating Engine

The Blade templating engine allows you to create dynamic views with ease. It is both powerful and lightweight, enabling the creation of responsive, feature-rich frontends.

e. Large Community and Packages

Laravel boasts a large community of developers, which means plenty of third-party packages, tutorials, and resources are available to assist in building an eCommerce site.

f. Scalability

Laravel’s flexible architecture makes it easy to scale, from small shops to large eCommerce platforms with thousands of products and high traffic volumes.

Prerequisites for Building an eCommerce Website with Laravel

Before you begin building your eCommerce website, ensure you have the following prerequisites:

Basic understanding of PHP and Laravel framework
PHP (preferably version 8.0 or higher) installed on your machine
Composer (Dependency Manager for PHP) installed
A database management system (MySQL or PostgreSQL recommended)
Familiarity with HTML, CSS, and JavaScript

Additionally, you should have a working knowledge of the following technologies:

Node.js and npm (for managing frontend packages like Bootstrap, Vue.js, etc.)
Git (for version control)

Setting Up the Laravel Environment

a. Install Laravel via Composer

To create a new Laravel project, run the following command in your terminal:

composer create-project --prefer-dist laravel/laravel ecommerce-website

b. Set Up a Database

Next, set up a MySQL (or PostgreSQL) database and configure Laravel to use it. Update the .env file in the Laravel project directory with your database credentials:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=ecommerce
DB_USERNAME=root
DB_PASSWORD=yourpassword

c. Migrate Database

Laravel uses migrations to handle database schema changes. Run the following command to create and apply the default Laravel migrations:

php artisan migrate

Now, you’re ready to start building the structure of your eCommerce website.

Planning Your eCommerce Website Structure

An eCommerce website usually consists of several essential features, such as:

Homepage (Displays featured products, categories, etc.)
Product Listing Pages (Displays all products or products by category)
Product Detail Pages (Shows detailed information about a single product)
Shopping Cart (Allows users to add and remove items from their cart)
Checkout and Payment (Facilitates order processing and payment)
User Accounts (For login, registration, and order history)

For this project, we’ll follow a modular approach by breaking down each component into separate Laravel models, controllers, and views.

Creating the Product Catalog

a. Define Product Model

In Laravel, models represent database tables. Create a Product model by running:

php artisan make:model Product -m

This command will generate a Product model and a migration file. Open the migration file (database/migrations/*_create_products_table.php) and define the schema for the products table:

public function up()
{
    Schema::create('products', function (Blueprint $table) {
        $table->id();
        $table->string('name');
        $table->text('description');
        $table->decimal('price', 8, 2);
        $table->string('image')->nullable();
        $table->timestamps();
    });
}

Run the migration to create the table:

php artisan migrate

b. Create a Controller

Next, create a ProductController to handle displaying the products:

php artisan make:controller ProductController

In the controller, add methods for listing all products and showing individual product details:

public function index()
{
    $products = Product::all();
    return view('products.index', compact('products'));
}

public function show($id)
{
    $product = Product::findOrFail($id);
    return view('products.show', compact('product'));
}

c. Set Up Views

Create the views for displaying the product catalog in resources/views/products/index.blade.php and show.blade.php. Here’s an example for the product listing page:

@extends('layouts.app')

@section('content')
    <div class="container">
        <h1>Product Catalog</h1>
        <div class="row">
            @foreach($products as $product)
                <div class="col-md-4">
                    <div class="card">
                        <img src="{{ $product->image }}" class="card-img-top" alt="{{ $product->name }}">
                        <div class="card-body">
                            <h5 class="card-title">{{ $product->name }}</h5>
                            <p class="card-text">{{ $product->description }}</p>
                            <p class="card-text">${{ $product->price }}</p>
                            <a href="{{ route('products.show', $product->id) }}" class="btn btn-primary">View Product</a>
                        </div>
                    </div>
                </div>
            @endforeach
        </div>
    </div>
@endsection

6. Building a Shopping Cart

a. Install Laravel Package for Cart

A popular package for handling shopping cart functionality is bumbummen99/laravel-shoppingcart. Install it via Composer:

composer require bumbummen99/laravel-shoppingcart

b. Configure the Cart

Add cart functionality in the CartController. For example, you can add an item to the cart like this:

public function addToCart(Request $request, $id)
{
    $product = Product::findOrFail($id);
    Cart::add($product->id, $product->name, 1, $product->price);
    return redirect()->route('cart.index');
}

c. Display Cart

Create a view for displaying the cart contents. In resources/views/cart/index.blade.php:

@extends('layouts.app')

@section('content')
    <div class="container">
        <h1>Your Shopping Cart</h1>
        <table class="table">
            <thead>
                <tr>
                    <th>Product</th>
                    <th>Quantity</th>
                    <th>Price</th>
                    <th>Total</th>
                </tr>
            </thead>
            <tbody>
                @foreach(Cart::content() as $item)
                    <tr>
                        <td>{{ $item->name }}</td>
                        <td>{{ $item->qty }}</td>
                        <td>${{ $item->price }}</td>
                        <td>${{ $item->total }}</td>
                    </tr>
                @endforeach
            </tbody>
        </table>
    </div>
@endsection

Integrating Payment Gateways

To process payments, you can integrate popular payment gateways like Stripe or PayPal.

a. Install Stripe Package

For Stripe, first, install the package:

composer require stripe/stripe-php

Configure your Stripe API keys in the .env file:

STRIPE_KEY=your-stripe-key
STRIPE_SECRET=your-stripe-secret

b. Create Payment Controller

Add a PaymentController that handles payment requests:

public function checkout()
{
    return view('checkout.index');
}

public function processPayment(Request $request)
{
    Stripe::setApiKey(env('STRIPE_SECRET'));

    $charge = Charge::create([
        'amount' => Cart::total() * 100

,
        'currency' => 'usd',
        'source' => $request->stripeToken,
        'description' => 'Order Payment',
    ]);

    Cart::destroy();
    return redirect()->route('confirmation');
}

Create the view for handling payment in resources/views/checkout/index.blade.php using Stripe’s Elements library.

User Authentication and Security

Laravel’s built-in authentication system provides a straightforward way to manage user login, registration, and account management. Run the following command to scaffold the authentication:

php artisan make:auth

This will generate views and controllers for user authentication.

Managing Orders and Inventory

You will need to create an Order model and associate it with users and products. The Order model can store essential order information like product details, quantity, and user ID. To manage inventory, create fields in the products table to track stock levels, and implement logic to reduce stock when an order is placed.

Optimizing Performance and Scalability

a. Caching

Laravel offers built-in support for caching mechanisms like Redis, which can significantly improve performance by storing frequently accessed data in memory.

b. Queue Management

You can use Laravel’s queue system to handle background tasks like sending emails or processing payments asynchronously, reducing response time for users.

Testing and Deployment

a. Unit Testing

Laravel comes with PHPUnit out of the box. Write tests to ensure the integrity of your eCommerce application by testing key functionalities like user registration, product management, and checkout.

b. Deployment

When you’re ready to deploy, use services like Forge or Envoyer to deploy your Laravel application smoothly. Ensure that your database is properly migrated and that your server environment meets Laravel’s requirements.
