Laravel, a popular PHP framework, has gained widespread recognition for its elegant syntax, powerful features, and developer-friendly environment. In this comprehensive guide, we will explore the step-by-step process of building enterprise-grade web applications with Laravel.

1. Understanding Laravel for Enterprise Web Applications

Introduction to Laravel

Laravel, an open-source PHP web framework, has gained immense popularity due to its elegant syntax, robust features, and developer-friendly environment. Tailored for modern web development, Laravel follows the MVC (Model-View-Controller) architecture, facilitating modular code organization and separation of concerns. Its expressive syntax allows developers to write clean and concise code, reducing development time and enhancing readability.

Laravel comes bundled with a plethora of features essential for building enterprise-grade applications, such as an ORM (Object-Relational Mapping) system called Eloquent, a powerful routing system, middleware for handling HTTP requests, Blade templating engine, and a convenient command-line interface, Artisan. Also, Laravel’s active and vibrant community ensures continuous improvement and provides a rich ecosystem of packages through Composer, the PHP dependency manager.

Laravel’s Ecosystem

Laravel’s ecosystem extends beyond its core features. Laravel Mix simplifies asset compilation and management, making it seamless to integrate CSS and JavaScript into your projects. Laravel Horizon provides a beautiful dashboard for monitoring and managing queue worker processes. Passport, another Laravel package, streamlines the implementation of OAuth2 and JWT authentication, vital for securing enterprise applications.

Furthermore, Laravel’s Forge and Vapor services offer robust solutions for server management and serverless deployment, respectively. These tools enhance the deployment process, making it efficient and scalable, crucial aspects of enterprise-level applications.

Why Choose Laravel for Enterprise Applications?

Several factors make Laravel an ideal choice for enterprise web applications. Firstly, Laravel prioritizes developer experience, offering an expressive syntax that reduces boilerplate code, leading to faster development cycles. The framework also promotes best practices, ensuring code consistency and maintainability across large codebases, which is essential for enterprise-scale projects.

Additionally, Laravel’s built-in features, like Eloquent ORM and Blade templating engine, contribute to the efficiency of development. Eloquent simplifies database interactions, making it easy to define relationships between models and perform complex queries, while Blade provides a lightweight and intuitive templating system for creating dynamic views.

Laravel’s commitment to security is another crucial factor for enterprise applications. The framework includes features like CSRF protection, input validation, and a powerful authentication system that enables developers to implement robust security measures seamlessly.

2. Setting Up Your Development Environment

Installing Laravel

Before diving into the development process, the first step is setting up a robust development environment. Laravel simplifies this process with its streamlined installation. The framework requires Composer, the PHP dependency manager, to be installed on your system. With Composer in place, you can create a new Laravel project effortlessly using the following command:

composer create-project --prefer-dist laravel/laravel your-project-name

This command fetches the latest version of Laravel and sets up a new project with the specified name. Once the installation is complete, you can navigate into the project directory and start the built-in development server with:

php artisan serve

This command launches the server, making your Laravel application accessible through a local URL. This straightforward setup allows developers to quickly get started with building and testing their applications.

Configuring Database Connections

Enterprise web applications often rely on complex database structures to store and retrieve data efficiently. Laravel simplifies database management through its elegant ORM, Eloquent. To configure your database settings, navigate to the .env file in the root of your Laravel project. Here, you can specify the database connection details such as database type, host, port, and credentials.

Laravel supports various database systems, including MySQL, PostgreSQL, SQLite, and SQL Server. By modifying the .env file, developers can seamlessly switch between database providers, offering flexibility based on the application’s requirements.

After configuring the database connection, you can use Laravel’s powerful Artisan command-line tool to generate migrations and seeders, providing a structured approach to database management. Migrations allow version control for database schema, making it easy to collaborate with other developers and maintain a consistent database structure across different environments.

Laravel Homestead for a Consistent Development Environment

Consistency across development environments is crucial, especially in enterprise scenarios where multiple developers may collaborate on a project. Laravel Homestead is a pre-packaged Vagrant box that provides a consistent, virtualized development environment for Laravel applications.

Homestead includes popular tools and services such as Nginx, PHP, MySQL, Redis, and more, configured to work seamlessly with Laravel. Setting up Homestead involves installing Vagrant and the Homestead box, followed by configuring your Laravel project to use this virtual environment.

By adopting Laravel Homestead, developers ensure that their local development environment mirrors the production environment closely. This consistency reduces the likelihood of bugs and issues arising due to differences in server configurations between development and production.

3. Designing the Database Schema

Defining Entities and Relationships

The foundation of any enterprise web application lies in its database schema. Laravel’s Eloquent ORM simplifies the process of defining and interacting with the database. Before creating tables and relationships, it’s crucial to identify the entities and their associations within the application.

Start by listing the main entities your application will manage. For instance, in an enterprise resource planning (ERP) application, entities could include Users, Companies, Products, Orders, and Invoices. Once identified, define the relationships between these entities. Laravel Eloquent supports relationships like one-to-one, one-to-many, and many-to-many, allowing you to model complex interactions seamlessly.

For example, a User may have multiple Orders, and an Order may belong to a Company. In Laravel, this relationship can be expressed through eloquent relationships:

// User model
public function orders()
{
    return $this->hasMany(Order::class);
}

// Order model
public function user()
{
    return $this->belongsTo(User::class);
}

Leveraging Laravel Migrations

With entities and relationships defined, Laravel’s migration system comes into play. Migrations are version control for the database, allowing you to modify the schema in a structured manner. Create a migration for each entity to define the corresponding database table.

Use the Artisan command-line tool to generate a migration:

php artisan make:migration create_orders_table

This command creates a new migration file in the database/migrations directory. Open the generated file and define the columns and relationships within the up method:

// In the up method
public function up()
{
    Schema::create('orders', function (Blueprint $table) {
        $table->id();
        $table->foreignId('user_id')->constrained();
        // Other columns
        $table->timestamps();
    });
}

Run the migration to create the table:

php artisan migrate

Migrations facilitate collaboration among developers, allowing them to synchronize their databases easily. Additionally, Laravel’s migration system helps roll back changes if necessary, maintaining a consistent database structure.

Seeding Data for Testing

For thorough testing and development, seed the database with sample data. Laravel’s database seeders allow you to populate tables with predefined data, ensuring that your application functions as expected in various scenarios.

Create a seeder for an entity using the following command:

php artisan make:seeder OrdersTableSeeder

Define the data to be inserted within the run method of the seeder:

public function run()
{
    // Seed orders table
    Order::factory(50)->create();
}

Run the seeder to populate the database:

php artisan db:seed --class=OrdersTableSeeder

This process of designing the database schema with entities, relationships, migrations, and seeders lays the groundwork for building a robust enterprise web application. Laravel’s Eloquent ORM and migration system empower developers to manage the database efficiently, ensuring a scalable and maintainable foundation for the application. The next steps involve building a robust authentication system to secure the application and creating a scalable user interface with Blade templates.

4. Building a Robust Authentication System

Laravel’s Authentication Scaffold

Authentication is a critical component of any enterprise web application. Laravel simplifies the implementation of a robust authentication system through its built-in authentication scaffolding. The scaffolding provides a pre-built set of controllers, views, and routes that handle common authentication tasks, such as user registration, login, and password reset.

To generate the authentication scaffolding, use the Artisan command:

php artisan make:auth

This command generates the necessary files and configurations in the resources/views/auth directory and sets up the routes in the routes/web.php file. The authentication controllers, like RegisterController, LoginController, and ForgotPasswordController, are also created.

The generated views and controllers can be customized to align with the specific requirements of the enterprise application. This customization allows developers to implement additional features, such as capturing extra user details during registration or integrating third-party authentication providers.

Customizing User Roles and Permissions

Enterprise applications often require role-based access control to manage permissions effectively. Laravel’s built-in middleware and authorization features make it seamless to implement roles and permissions.

Create roles and permissions tables in the database using migrations, and then establish relationships with the User model. For example, a User may have a role of ‘Admin,’ ‘Manager,’ or ‘Employee,’ each with different levels of access. Utilize Laravel’s middleware to restrict access to specific routes based on the user’s role.

// Define roles and permissions in the User model
public function roles()
{
    return $this->belongsToMany(Role::class);
}

public function hasRole($role)
{
    return $this->roles()->where('name', $role)->exists();
}

Implementing Two-Factor Authentication

Enhance the security of your enterprise application by implementing two-factor authentication (2FA). Laravel supports 2FA out of the box with the Laravel Two-Factor Authentication package. Install the package using Composer:

composer require u2f-php/laravel-u2f

Configure the package and implement 2FA in the LoginController. Users can then enable 2FA for their accounts, adding an extra layer of protection to sensitive enterprise data.

// Enable 2FA in LoginController
use U2FAuth;

public function showLoginForm()
{
    return view('auth.login')->with('u2f', U2FAuth::generateRequest());
}

public function login(Request $request)
{
    // Validate credentials and 2FA
    $this->validateLogin($request);

    if (U2FAuth::isAuthenticated()) {
        // User successfully authenticated with 2FA
        return $this->sendLoginResponse($request);
    }

    // Prompt for 2FA authentication
    return view('auth.u2f', [
        'u2f' => U2FAuth::generateRequest()
    ]);
}

By customizing Laravel’s authentication system, integrating role-based access control, and implementing two-factor authentication, developers can ensure a robust and secure user authentication experience for enterprise applications. The next steps involve creating a scalable user interface with Blade templates and leveraging Laravel’s Eloquent ORM for efficient database interactions.

5. Creating a Scalable User Interface with Blade Templates

Introduction to Blade

Blade is Laravel’s templating engine, designed to make the process of creating views and UI components straightforward and expressive. It allows developers to write templates using plain PHP code mixed with Blade syntax, providing a clean and intuitive way to build dynamic interfaces.

Blade templates are stored in the resources/views directory. They use the .blade.php file extension and can include variables, control structures, and even extend layouts to ensure a consistent design across the application.

Building Layouts and Views

Creating a scalable user interface begins with designing layouts and views. A layout serves as a template that defines the overall structure of a page, while views represent specific sections or pages within the application.

Start by creating a main layout file, for example, layouts/app.blade.php. This file can include the HTML structure, header, footer, and any common elements across multiple pages. Use Blade’s @yield directive to define sections that will be filled in by individual views.

<!-- layouts/app.blade.php -->
<html>
<head>
<title>@yield('title')</title>
</head>
<body>
@yield('content')
</body>
</html>

Extend this layout in specific views and fill in the content section:

<!-- views/home.blade.php -->
@extends('layouts.app')
@section('title', 'Home Page')
@section('content')
<h1>Welcome to the Home Page</h1>
<!-- Additional content specific to the home page -->
@endsection

This modular approach ensures a consistent structure across the application while allowing for flexibility in individual views.

Blade Directives for Efficient Template Design

Blade provides several directives that simplify common tasks and enhance template design efficiency. Some notable directives include:

Conditionals:

Blade’s @if, @else, and @unless directives enable developers to implement conditional logic directly in the templates. This is useful for showing or hiding elements based on certain conditions.

@if($user->isAdmin())
<p>Welcome, Admin!</p>
@else
<p>Welcome, User!</p>
@endif

Loops:

Blade’s @foreach, @for, and @while directives facilitate the iteration over arrays or collections. This is particularly useful for displaying dynamic lists of data.

<ul>
@foreach($items as $item)
<li>{{ $item }}</li>
@endforeach
</ul>

Includes and Components:

Blade allows for the inclusion of partial views or components using @include and @component directives, promoting code reusability.

<!-- Include a partial view -->
@include('partials.header')

<!-- Create a reusable component -->
@component('components.alert', ['type' => 'success'])
This is a success alert!
@endcomponent

By leveraging Blade’s features and directives, developers can create a scalable and maintainable user interface for enterprise web applications. This, combined with Laravel’s powerful routing system and middleware, sets the stage for efficient navigation and interaction within the application. The subsequent sections will explore using Laravel’s Eloquent ORM for database interactions and implementing robust form handling.

6. Leveraging Laravel’s Eloquent ORM

ORM Basics

Object-Relational Mapping (ORM) simplifies database interactions by mapping database tables to objects in code. Laravel’s Eloquent ORM is an eloquent solution that allows developers to interact with databases using expressive, object-oriented syntax. It abstracts away the complexities of SQL queries and provides a convenient and intuitive way to work with databases.

Eloquent models represent database tables and encapsulate the business logic associated with them. Models extend the Illuminate\Database\Eloquent\Model class, gaining access to a multitude of features for querying and manipulating data.

Defining Models and Relationships

Start by creating a model for each entity in your database. For instance, if you have a User entity, create a User model:

php artisan make:model User

Define the model’s properties and relationships within the generated model file. Relationships, such as one-to-many or many-to-many, are expressed using Eloquent’s methods like hasOne, hasMany, belongsTo, and belongsToMany.

// User model
class User extends Model
{
// Define the table associated with the model
protected $table = 'users';

// Define the primary key
protected $primaryKey = 'id';

// Define relationships
public function orders()

{
return $this->hasMany(Order::class);
}
}

Eloquent automatically infers the foreign key and other details based on naming conventions, simplifying the process of defining relationships.

Querying the Database with Eloquent

Eloquent provides a fluent query builder that allows developers to construct queries using method chaining. This approach not only enhances readability but also provides a secure way to build queries, preventing SQL injection attacks.

Basic queries using Eloquent are concise and expressive:

// Retrieve all users
$users = User::all();

// Find a user by ID
$user = User::find(1);

// Create a new user
$newUser = User::create([
'name' => 'John Doe',
'email' => '[email protected]',
'password' => bcrypt('password'),
]);

// Update a user
$user->update(['name' => 'Updated Name']);

// Delete a user
$user->delete();

Eloquent also supports advanced querying features like eager loading, where relationships are loaded along with the main model to reduce the number of database queries.

// Eager loading orders along with users
$users = User::with('orders')->get();

By leveraging Eloquent’s ORM capabilities, developers can streamline database interactions, making it easier to manage and manipulate data within their Laravel applications. The next step involves implementing robust form handling to capture user input and facilitate data submission within the enterprise web application.

7. Implementing Robust Form Handling

Laravel Form Requests

Forms are essential components of web applications, enabling users to interact with and submit data. Laravel simplifies the process of handling form submissions by providing Form Request validation. Form Requests allow developers to centralize validation logic, making it reusable across controllers and ensuring that input data meets specified criteria.

Create a Form Request using the Artisan command:

php artisan make:request CreateUserRequest

Define validation rules within the generated form request file, located in the app/Http/Requests directory:

// CreateUserRequest.php
public function rules()
{
return [
'name' => 'required|string|max:255',
'email' => 'required|email|unique:users',
'password' => 'required|min:8|confirmed
];
}

In the corresponding controller method, type-hint the form request to automatically validate incoming data:

// UserController.php
public function store(CreateUserRequest $request)
{
// Data is already validated; proceed with storing user
$user = User::create($request->validated());
// Additional logic as needed
}

Validating User Input

Laravel’s validation rules cover a wide range of scenarios, ensuring that submitted data meets specific requirements. Rules can be applied to form requests or directly within controller methods. For example, to validate a simple login form:

// LoginController.php
public function login(Request $request)
{
$request->validate([
'email' => 'required|email',
'password' => 'required',
]);
// Authentication logic
}

Custom validation messages and error responses can be defined to provide meaningful feedback to users.

Handling Form Submissions

Once data is validated, the next step is handling form submissions. In Laravel, this typically involves storing data in the database or triggering other actions. Utilize Eloquent models to interact with the database, ensuring that data is securely persisted.

// Store user data
$user = new User();
$user->name = $request->input('name');
$user->email = $request->input('email');
$user->password = bcrypt($request->input('password'));
$user->save();

In more complex scenarios, additional processing or event triggering may be required. Laravel’s event system can be used to decouple form submission logic and execute actions based on specific events.

// Trigger an event after user creation
event(new UserCreated($user));

By implementing robust form handling practices, developers can ensure data integrity, security, and user-friendly experiences within their enterprise web applications. The subsequent sections will delve into integrating external services and APIs to enhance application functionality and security.

8. Integrating External Services and APIs

Communicating with External APIs

Enterprise web applications often need to interact with external services and APIs to enhance functionality or access third-party resources. Laravel provides a convenient HTTP client to streamline communication with external APIs.

To make HTTP requests, use Laravel’s HTTP client by invoking the get, post, put, or delete methods. For example, to fetch data from a hypothetical external API:

use Illuminate\Support\Facades\Http;
$response = Http::get('https://api.example.com/data');
$data = $response->json();
// Process and use the retrieved data

Laravel’s HTTP client simplifies common tasks like handling response status codes, setting headers, and parsing JSON responses.

Integrating Third-Party Services

Laravel’s flexibility extends to integrating third-party services seamlessly. Many services provide Laravel-specific packages or SDKs that simplify the integration process.

For instance, integrating with a payment gateway might involve installing a Laravel package, configuring API credentials, and handling responses:

composer require some-payment-gateway/laravel-package

// In a controller or service
use SomePaymentGateway;
$response = SomePaymentGateway::charge($amount, $creditCardDetails);
// Process the payment response

By abstracting away the complexities of external integrations, Laravel allows developers to focus on application logic rather than intricate API details.

Handling Webhooks

Webhooks are a common mechanism for real-time communication between systems. Laravel provides a straightforward way to handle incoming webhooks using its routing and controller system.

Define a route to handle the incoming webhook:

// routes/web.php
Route::post('/webhook', 'WebhookController@handle');

Create a controller to process the incoming webhook payload:

php artisan make:controller WebhookController

// WebhookController.php
public function handle(Request $request)
{
// Process the incoming webhook payload
$data = $request->all();

// Perform actions based on the webhook data
}

Laravel’s simplicity and consistency make it an ideal choice for handling various integration scenarios. Whether communicating with external APIs, integrating third-party services, or managing webhooks, Laravel’s features and conventions provide a cohesive and efficient development experience.

The subsequent sections will focus on securing Laravel applications by implementing robust security measures, including protection against common web vulnerabilities and the implementation of content security policies.

9. Securing Your Laravel Application

Understanding Security Best Practices

Security is a paramount concern in enterprise web applications. Laravel, known for its commitment to security, provides a range of features and practices to safeguard applications against common threats. Embracing security best practices is crucial to protect sensitive data and ensure the integrity of your application.

Some essential security practices include:

Data Validation:

Validate user input to prevent common vulnerabilities such as SQL injection and Cross-Site Scripting (XSS). Laravel’s built-in validation system, as discussed earlier, is a powerful tool for this purpose.

Cross-Site Request Forgery (CSRF) Protection:

Laravel automatically includes CSRF tokens in forms to protect against CSRF attacks. Ensure that forms in your application include the @csrf Blade directive to generate the token.

<form method="POST" action="/example">
@csrf
<!-- Other form fields -->
</form>

Cross-Site Scripting (XSS) Protection:

Laravel’s Blade templating engine automatically escapes output by default, mitigating the risk of XSS attacks. However, be cautious when outputting raw user input, and consider using the @verbatim directive when necessary.

@verbatim
{!! $rawHtml !!}
@endverbatim

Protecting Against Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF)

In addition to the aforementioned CSRF protection, Laravel provides additional tools to enhance security. For example, the X-XSS-Protection header can be added to HTTP responses to enable the browser’s built-in XSS protection.

// In a middleware or directly in a controller
public function someAction()
{
return response('Hello, World!')->header('X-XSS-Protection', '1; mode=block');
}

Furthermore, Laravel’s encrypt and decrypt functions can be used to secure sensitive data. This is particularly useful when storing and transmitting confidential information, such as API keys or authentication tokens.

$encrypted = encrypt($sensitiveData); 
$decrypted = decrypt($encrypted);

Implementing Content Security Policy (CSP)

Content Security Policy (CSP) is a powerful defense against various types of attacks, including XSS. Laravel provides middleware to easily implement CSP headers in your application.

// In a middleware or directly in a controller 
public function someAction()
{
$response = response('Hello, World!');

// Enable Content Security Policy
$csp = "default-src 'self'; script-src 'self' 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline';";

return $response->header('Content-Security-Policy', $csp);
}

Customize the CSP policy based on your application’s needs, allowing only trusted sources for scripts, styles, and other resources.

By adhering to these security best practices and leveraging Laravel’s built-in security features, developers can fortify their enterprise web applications against common threats. The subsequent sections will explore strategies for optimizing performance and scalability, ensuring applications remain responsive under heavy loads.

10. Optimizing Performance and Scalability

Caching Strategies in Laravel

Efficient caching is a key factor in optimizing the performance of Laravel applications. Laravel provides a comprehensive caching system that supports various drivers, including file, database, Redis, and more.

To cache data, you can use Laravel’s cache helper:

$value = cache('key');

if (is_null($value)) {
// Data is not in the cache, retrieve and store it
$value = fetchDataFromDatabase();
cache(['key' => $value], now()->addMinutes(10));
}

// Use the cached value

Leveraging caching strategically reduces the load on your application, especially for data that doesn’t change frequently.

Database Optimization Techniques

Database performance is critical for the overall responsiveness of an enterprise application. Laravel provides tools and techniques to optimize database interactions:

Eloquent Eager Loading:

Use eager loading to retrieve related models in a single query rather than making separate queries for each relationship. This reduces the number of database queries, improving performance.

// Eager loading orders along with users 
$users = User::with('orders')->get();

Database Indexing:

Properly indexing database tables enhances query performance. Identify columns frequently used in queries and add indexes to them.

Schema::table('users', function ($table) {
$table->index('email');
});

Query Optimization:

Use Laravel’s query builder methods effectively to optimize database queries. Minimize the use of SELECT * and retrieve only the columns needed for a specific operation.

$users = DB::table('users')->select('name', 'email')->get();

Scaling Laravel Applications with Load Balancers

As enterprise applications grow, scaling becomes a necessity to handle increased traffic and ensure consistent performance. Load balancing is a common technique to distribute incoming requests across multiple servers, preventing any single server from becoming a bottleneck.

Popular load-balancing strategies include:

Round Robin:

Requests are distributed sequentially to servers in the order they appear in the server list.

Least Connections:

Requests are directed to the server with the fewest active connections, distributing the load more evenly.

IP Hash:

The client’s IP address is used to determine which server receives the request, ensuring consistency for subsequent requests from the same client.

Laravel applications can be easily scaled horizontally by deploying them across multiple servers and configuring a load balancer to distribute traffic. Laravel Forge, a server management tool, simplifies the process of setting up load balancers and scaling applications.

By implementing caching strategies, optimizing database interactions, and leveraging load balancing techniques, developers can ensure their Laravel applications are well-equipped to handle increased traffic and maintain optimal performance. The subsequent sections will focus on testing and quality assurance, exploring tools and methodologies to ensure the reliability and stability of enterprise web applications.

11. Testing and Quality Assurance

Writing Unit Tests with PHPUnit

Quality assurance is an integral part of developing robust and reliable enterprise web applications. Laravel promotes testing through PHPUnit, a popular testing framework for PHP. Writing unit tests helps identify and fix issues early in the development process, ensuring the stability of your application.

Laravel provides a convenient testing environment and includes PHPUnit by default. Create a test class using the Artisan command:

php artisan make:test UserTest

Write test methods within the generated test class to validate specific functionality:

// UserTest.php
use Tests\TestCase; 
use App\Models\User; 

class UserTest extends TestCase 
{
public function test_can_create_user()
{
$user = User::factory()->create();

$this->assertInstanceOf(User::class, $user); 
$this->assertDatabaseHas('users', ['id' => $user->id]);

}
// Additional test methods
}

Run the tests with:

php artisan test

Leveraging PHPUnit for unit testing ensures that individual components of your application function as expected.

Laravel Dusk for Browser Testing

Beyond unit tests, browser testing is crucial to validate the behavior of your application from a user’s perspective. Laravel Dusk provides an expressive and fluent API for browser automation testing.

Create a Dusk test using the Artisan command:

php artisan dusk:make UserBrowserTest

Write test methods to simulate user interactions and verify the expected outcomes:

// UserBrowserTest.php
use Laravel\Dusk\Browser; 
use Tests\DuskTestCase;

class UserBrowserTest extends DuskTestCase 
{

public function test_user_can_login()
{
$this->browse(function (Browser $browser) {
$browser->visit('/login')
->type('email', '[email protected]')
->type('password', 'password')
->press('Login')
->assertPathIs('/dashboard');
});
}

// Additional test methods
}

Run Dusk tests with:

php artisan dusk

Laravel Dusk allows for end-to-end testing, ensuring that user interfaces and interactions are functioning correctly.

Continuous Integration with Laravel Forge

Continuous Integration (CI) is a crucial aspect of maintaining code quality and catching issues early. Laravel Forge, a server management tool, integrates seamlessly with popular CI services like GitHub Actions and provides a smooth workflow for automating tests.

Configure CI workflows to run unit tests, browser tests, and other checks automatically whenever changes are pushed to the repository. Laravel Forge’s integration simplifies the setup process and ensures a consistent testing environment.
