In this first tutorial, we'll walk you through setting up your development environment for Laravel, including installing PHP, Composer, and the Laravel framework itself. Let's get started!
php -v
If you don't have PHP installed or need to upgrade, visit the official PHP website and follow the instructions for your operating system.
Install Composer: Composer is a dependency manager for PHP, and Laravel requires it for installation and dependency management. To install Composer, visit the official Composer website and follow the installation instructions for your operating system.
Install Laravel: With PHP and Composer installed, you can now install Laravel. Open your CLI and run the following command:
composer global require laravel/installer
This command installs the Laravel installer globally on your system.
laravel new your-project-name
Replace 'your-project-name' with the desired name for your project. This command creates a new Laravel project in a folder with the specified name.
php artisan serve
This command starts the development server on port 8000 by default. You can now visit http://localhost:8000 in your browser to see your new Laravel application in action!
Congratulations! You have successfully set up your Laravel development environment and created a new Laravel project. In the next tutorial, we'll dive into Laravel routing and controllers, exploring how to handle incoming requests and direct them to the appropriate application logic.
In this tutorial, we'll explore Laravel's routing system and how to create controllers to handle the application logic. Routing is essential for directing incoming requests to the appropriate controllers, which then process the requests and return responses.
routes/web.php file. By default, you'll find a basic route that returns a view:
Route::get('/', function () {
return view('welcome');
});
This code defines a route for the root path (/) using the get HTTP method. When a user visits the root path, the closure function is executed, returning the 'welcome' view.
php artisan make:controller YourControllerName
Replace 'YourControllerName' with the desired name for your controller. This command creates a new controller file in the app/Http/Controllers directory.
public function index()
{
return view('index');
}
This method returns the 'index' view when called.
routes/web.php file, create a new route that maps to your controller method:
use App\Http\Controllers\YourControllerName;
Route::get('/index', [YourControllerName::class, 'index']);
Replace 'YourControllerName' with the name of your controller. This code creates a route for the /index path, mapping it to the index method of your controller.
resources/views directory, create a new Blade template file called index.blade.php and add some HTML content:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Index</title>
</head>
<body>
<h1>Welcome to the Index Page</h1>
</body>
</html>
This code defines a simple HTML page with a heading.
php artisan serve, and visit http://localhost:8000/index in your browser. You should see the 'Welcome to the Index Page' heading, confirming that your route and controller are working correctly.Great job! You've successfully set up routing and controllers in your Laravel application. In the next tutorial, we'll explore creating views and leveraging Laravel's powerful Blade template engine to create dynamic and reusable templates.
In this tutorial, we'll explore how to create views using Laravel's powerful Blade template engine. Blade provides a clean and elegant syntax for creating dynamic and reusable templates, making it easy to separate your application's presentation layer from its logic.
Understanding Blade Templates: Blade is the default template engine in Laravel. It provides a simple and elegant syntax for creating HTML templates with embedded PHP code. Blade template files have the .blade.php extension and are stored in the resources/views directory.
Creating a Layout Template: To demonstrate the power of Blade, let's create a layout template for your application. In the resources/views directory, create a new Blade template file called layout.blade.php and add the following code:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>@yield('title')</title>
</head>
<body>
<div class="container">
@yield('content')
</div>
</body>
</html>
In this code, we use the @yield directive to define placeholders for the title and content. These placeholders will be filled with data from child templates that extend this layout.
@extends directive. Open your index.blade.php file and replace the existing code with the following:
@extends('layout')
@section('title', 'Index')
@section('content')
<h1>Welcome to the Index Page</h1>
@endsection
This code extends the layout.blade.php template and fills the title and content placeholders with the specified data.
about.blade.php file in the resources/views directory with the following code:
@extends('layout')
@section('title', 'About')
@section('content')
<h1>About Us</h1>
<p>We are a leading web development company.</p>
@endsection
routes/web.php file, create new routes for your additional views:
use App\Http\Controllers\YourControllerName;
Route::get('/about', [YourControllerName::class, 'about']);
In your controller, add a new method for handling the about route:
public function about()
{
return view('about');
}
php artisan serve, and visit http://localhost:8000/about in your browser. You should see the 'About Us' page, confirming that your Blade templates are working correctly.Well done! You've successfully created views and leveraged Laravel's Blade template engine to build dynamic and reusable templates. In the next tutorial, we'll explore the Eloquent ORM, which simplifies database interactions and makes it easy to work with your application's data.
In this tutorial, we'll explore Laravel's Eloquent ORM (Object-Relational Mapping), which provides a simple and elegant way to interact with your application's database. With Eloquent, you can work with database tables as if they were objects, making it easy to create, retrieve, update, and delete records.
.env file in your Laravel project and update the following values to match your database settings:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name
DB_USERNAME=your_database_user
DB_PASSWORD=your_database_password
Replace your_database_name, your_database_user, and your_database_password with your actual database information.
php artisan make:model YourModelName -m
Replace 'YourModelName' with the desired name for your model. The -m flag generates a migration file, which we'll use to create the database table.
app/Models directory and define the attributes that correspond to the columns in your database table:
protected $fillable = ['attribute1', 'attribute2', 'attribute3'];
Replace 'attribute1', 'attribute2', and 'attribute3' with your actual column names.
database/migrations directory. Define the schema for your database table within the up method:
public function up()
{
Schema::create('your_table_name', function (Blueprint $table) {
$table->id();
$table->string('attribute1');
$table->text('attribute2');
$table->integer('attribute3');
$table->timestamps();
});
}
Replace 'your_table_name', 'attribute1', 'attribute2', and 'attribute3' with your actual table and column names.
php artisan migrate
This command runs all pending migrations, creating the database table with the schema you defined.
YourModelName::create([
'attribute1' => 'value1',
'attribute2' => 'value2',
'attribute3' => 42,
]);
Replace 'YourModelName', 'attribute1', 'attribute2', 'attribute3', 'value1', 'value2', and 42 with your actual model and attribute names and values.
Congratulations! You've successfully set up and used Eloquent ORM to interact with your application's database. In the next tutorial, we'll explore user authentication and authorization, which are essential features for many web applications.
In this tutorial, we'll explore Laravel's built-in user authentication and authorization features, which are essential for securing many web applications. Laravel provides a simple and elegant way to manage user registration, authentication, password resets, and more.
composer require laravel/breeze --dev
Next, run the following command to install the Breeze scaffolding:
php artisan breeze:install
Finally, run the following command to compile the frontend assets:
npm install && npm run dev
Understanding the Authentication Scaffolding: Laravel Breeze installs several components, including authentication controllers, views, routes, and middleware. You'll find the views in the resources/views/auth directory, and the controllers in the app/Http/Controllers/Auth directory. The routes are defined in routes/auth.php.
Registering and Authenticating Users: With Laravel Breeze installed, your application now has user registration and authentication functionality. Visit http://localhost:8000/register in your browser to register a new user. After registering, you'll be automatically logged in and redirected to the dashboard.
Protecting Routes with Middleware: To protect specific routes and ensure that only authenticated users can access them, use the auth middleware. In your routes/web.php file, wrap the routes you want to protect in a route group with the auth middleware:
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\YourControllerName;
Route::middleware(['auth'])->group(function () {
Route::get('/protected-route', [YourControllerName::class, 'protectedRoute']);
});
Replace 'YourControllerName' and 'protectedRoute' with your actual controller and method names.
php artisan make:policy YourPolicyName --model=YourModelName
Replace 'YourPolicyName' and 'YourModelName' with your desired policy and model names. This command creates a new policy file in the app/Policies directory.
public function update(User $user, YourModelName $yourModelName)
{
return $user->id === $yourModelName->user_id;
}
In your controller, use the authorize method to check if the user has permission to perform the specified action:
public function update(Request $request, YourModelName $yourModelName)
{
$this->authorize('update', $yourModelName);
// Your update logic here
}
Great job! You've successfully set up user authentication and authorization in your Laravel application. With these powerful features, you can now secure your application and ensure that only authorized users can access specific resources and perform certain actions.
In this final tutorial, we'll discuss deploying your Laravel application to a live server. Deploying a Laravel application involves several steps, including transferring your files to the server, configuring the environment, and setting up the database.
Choose a Hosting Provider: First, choose a suitable hosting provider for your Laravel application. There are many hosting providers available, including shared hosting, virtual private servers (VPS), and cloud hosting services. Some popular options for Laravel applications are DigitalOcean, Heroku, and Laravel Forge.
Transfer Your Files to the Server: Use a secure file transfer method, such as SFTP or SCP, to transfer your Laravel project files to your hosting provider. Be sure to upload all files, including your public and storage directories.
Configure Your Environment: On the server, create a new .env file and configure the environment variables to match your production settings. Be sure to set the APP_ENV variable to production and the APP_DEBUG variable to false. Also, configure your database connection settings, as well as any other environment-specific settings.
Install Dependencies: On the server, navigate to your project's root directory and run the following command to install your Composer dependencies:
composer install --optimize-autoloader --no-dev
This command installs your dependencies and optimizes the autoloader for production.
php artisan migrate --force
The --force flag is required when running migrations in production.
php artisan config:cache
php artisan route:cache
php artisan view:cache
These commands cache your configuration, routes, and views, improving your application's performance in production.
Configure Your Web Server: Set up your web server to serve your Laravel application. You'll need to configure your server to point the document root to the public directory of your Laravel application. If you're using Apache, you may also need to configure the .htaccess file in the public directory.
Test Your Application: Visit your application's domain in your browser to ensure that everything is working correctly. Be sure to test all functionality, including user registration, authentication, and any other features you've implemented.
Congratulations! You've successfully deployed your Laravel application to a live server. Your application is now accessible to users around the world, and you can continue to build and improve your application as needed.
