[Laravel 11] Explain blade: Introduction

Blade is the simple, yet powerful templating engine that is included with Laravel. Unlike some PHP templating engines, Blade does not restrict you from using plain PHP code in your templates. In fact, all Blade templates are compiled into plain PHP code and cached until they are modified, meaning Blade adds essentially zero overhead to your application. Blade template files use the .blade.php file extension and are typically stored in the resources/views directory.

Blade views may be returned from routes or controllers using the global view helper. Of course, as mentioned in the documentation on views, data may be passed to the Blade view using the view helper's second argument:

    Route::get('/', function () {
        return view('greeting', ['name' => 'Finn']);
    });

<a name="supercharging-blade-with-livewire"></a>
[Laravel 11] Explain blade: Supercharging Blade With Livewire

Want to take your Blade templates to the next level and build dynamic interfaces with ease? Check out Laravel Livewire. Livewire allows you to write Blade components that are augmented with dynamic functionality that would typically only be possible via frontend frameworks like React or Vue, providing a great approach to building modern, reactive frontends without the complexities, client-side rendering, or build steps of many JavaScript frameworks.

<a name="displaying-data"></a>
[Laravel 11] Explain blade: Displaying Data

You may display data that is passed to your Blade views by wrapping the variable in curly braces. For example, given the following route:

    Route::get('/', function () {
        return view('welcome', ['name' => 'Samantha']);
    });

You may display the contents of the name variable like so:

> [!NOTE]  
> Blade's {{ }} echo statements are automatically sent through PHP's htmlspecialchars function to prevent XSS attacks.

You are not limited to displaying the contents of the variables passed to the view. You may also echo the results of any PHP function. In fact, you can put any PHP code you wish inside of a Blade echo statement:

<a name="html-entity-encoding"></a>
[Laravel 11] Explain blade: HTML Entity Encoding

By default, Blade (and the Laravel e function) will double encode HTML entities. If you would like to disable double encoding, call the Blade::withoutDoubleEncoding method from the boot method of your AppServiceProvider:

    <?php

    namespace App\Providers;

    use Illuminate\Support\Facades\Blade;
    use Illuminate\Support\ServiceProvider;

    class AppServiceProvider extends ServiceProvider
    {
        /**
         * Bootstrap any application services.
         */
        public function boot(): void
        {
            Blade::withoutDoubleEncoding();
        }
    }

[Laravel 11] Explain broadcasting: Introduction

In many modern web applications, WebSockets are used to implement realtime, live-updating user interfaces. When some data is updated on the server, a message is typically sent over a WebSocket connection to be handled by the client. WebSockets provide a more efficient alternative to continually polling your application's server for data changes that should be reflected in your UI.

For example, imagine your application is able to export a user's data to a CSV file and email it to them. However, creating this CSV file takes several minutes so you choose to create and mail the CSV within a queued job. When the CSV has been created and mailed to the user, we can use event broadcasting to dispatch an App\Events\UserDataExported event that is received by our application's JavaScript. Once the event is received, we can display a message to the user that their CSV has been emailed to them without them ever needing to refresh the page.

To assist you in building these types of features, Laravel makes it easy to "broadcast" your server-side Laravel events over a WebSocket connection. Broadcasting your Laravel events allows you to share the same event names and data between your server-side Laravel application and your client-side JavaScript application.

The core concepts behind broadcasting are simple: clients connect to named channels on the frontend, while your Laravel application broadcasts events to these channels on the backend. These events can contain any additional data you wish to make available to the frontend.

<a name="supported-drivers"></a>
[Laravel 11] Explain broadcasting: Server Side Installation

To get started using Laravel's event broadcasting, we need to do some configuration within the Laravel application as well as install a few packages.

Event broadcasting is accomplished by a server-side broadcasting driver that broadcasts your Laravel events so that Laravel Echo (a JavaScript library) can receive them within the browser client. Don't worry - we'll walk through each part of the installation process step-by-step.

<a name="configuration"></a>
[Laravel 11] Explain broadcasting: Configuration

All of your application's event broadcasting configuration is stored in the config/broadcasting.php configuration file. Don't worry if this directory does not exist in your application; it will be created when you run the install:broadcasting Artisan command.

Laravel supports several broadcast drivers out of the box: Laravel Reverb, Pusher Channels, Ably, and a log driver for local development and debugging. Additionally, a null driver is included which allows you to disable broadcasting during testing. A configuration example is included for each of these drivers in the config/broadcasting.php configuration file.

[Laravel 11] Explain cache: Introduction

Some of the data retrieval or processing tasks performed by your application could be CPU intensive or take several seconds to complete. When this is the case, it is common to cache the retrieved data for a time so it can be retrieved quickly on subsequent requests for the same data. The cached data is usually stored in a very fast data store such as Memcached or Redis.

Thankfully, Laravel provides an expressive, unified API for various cache backends, allowing you to take advantage of their blazing fast data retrieval and speed up your web application.

<a name="configuration"></a>
[Laravel 11] Explain cache: Configuration

Your application's cache configuration file is located at config/cache.php. In this file, you may specify which cache store you would like to be used by default throughout your application. Laravel supports popular caching backends like Memcached, Redis, DynamoDB, and relational databases out of the box. In addition, a file based cache driver is available, while array and "null" cache drivers provide convenient cache backends for your automated tests.

The cache configuration file also contains a variety of other options that you may review. By default, Laravel is configured to use the database cache driver, which stores the serialized, cached objects in your application's database.

<a name="driver-prerequisites"></a>
[Laravel 11] Explain cache: Memcached

Using the Memcached driver requires the Memcached PECL package to be installed. You may list all of your Memcached servers in the config/cache.php configuration file. This file already contains a memcached.servers entry to get you started:

    'memcached' => [
        // ...

        'servers' => [
            [
                'host' => env('MEMCACHED_HOST', '127.0.0.1'),
                'port' => env('MEMCACHED_PORT', 11211),
                'weight' => 100,
            ],
        ],
    ],

If needed, you may set the host option to a UNIX socket path. If you do this, the port option should be set to 0:

    'memcached' => [
        // ...

        'servers' => [
            [
                'host' => '/var/run/memcached/memcached.sock',
                'port' => 0,
                'weight' => 100
            ],
        ],

[Laravel 11] Explain cashier paddle: Introduction

> [!WARNING]  
> This documentation is for Cashier Paddle 2.x's integration with Paddle Billing. If you're still using Paddle Classic, you should use Cashier Paddle 1.x.

Laravel Cashier Paddle provides an expressive, fluent interface to Paddle's subscription billing services. It handles almost all of the boilerplate subscription billing code you are dreading. In addition to basic subscription management, Cashier can handle: swapping subscriptions, subscription "quantities", subscription pausing, cancelation grace periods, and more.

Before digging into Cashier Paddle, we recommend you also review Paddle's concept guides and API documentation.

<a name="upgrading-cashier"></a>
[Laravel 11] Explain cashier paddle: Installation

First, install the Cashier package for Paddle using the Composer package manager:

Next, you should publish the Cashier migration files using the vendor:publish Artisan command:

Then, you should run your application's database migrations. The Cashier migrations will create a new customers table. In addition, new subscriptions and subscription_items tables will be created to store all of your customer's subscriptions. Lastly, a new transactions table will be created to store all of the Paddle transactions associated with your customers:

> [!WARNING]  
> To ensure Cashier properly handles all Paddle events, remember to set up Cashier's webhook handling.

<a name="paddle-sandbox"></a>
[Laravel 11] Explain cashier paddle: Paddle Sandbox

During local and staging development, you should register a Paddle Sandbox account. This account will give you a sandboxed environment to test and develop your applications without making actual payments. You may use Paddle's test card numbers to simulate various payment scenarios.

When using the Paddle Sandbox environment, you should set the PADDLE_SANDBOX environment variable to true within your application's .env file:

After you have finished developing your application you may apply for a Paddle vendor account. Before your application is placed into production, Paddle will need to approve your application's domain.

<a name="configuration"></a>
[Laravel 11] Explain collections: Introduction

The Illuminate\Support\Collection class provides a fluent, convenient wrapper for working with arrays of data. For example, check out the following code. We'll use the collect helper to create a new collection instance from the array, run the strtoupper function on each element, and then remove all empty elements:

    $collection = collect(['taylor', 'abigail', null])->map(function (?string $name) {
        return strtoupper($name);
    })->reject(function (string $name) {
        return empty($name);
    });

As you can see, the Collection class allows you to chain its methods to perform fluent mapping and reducing of the underlying array. In general, collections are immutable, meaning every Collection method returns an entirely new Collection instance.

<a name="creating-collections"></a>
[Laravel 11] Explain collections: Extending Collections

Collections are "macroable", which allows you to add additional methods to the Collection class at run time. The Illuminate\Support\Collection class' macro method accepts a closure that will be executed when your macro is called. The macro closure may access the collection's other methods via $this, just as if it were a real method of the collection class. For example, the following code adds a toUpper method to the Collection class:

    use Illuminate\Support\Collection;
    use Illuminate\Support\Str;

    Collection::macro('toUpper', function () {
        return $this->map(function (string $value) {
            return Str::upper($value);
        });
    });

    $collection = collect(['first', 'second']);

    $upper = $collection->toUpper();

    // ['FIRST', 'SECOND']

Typically, you should declare collection macros in the boot method of a service provider.

<a name="macro-arguments"></a>
[Laravel 11] Explain collections: Macro Arguments

If necessary, you may define macros that accept additional arguments:

    use Illuminate\Support\Collection;
    use Illuminate\Support\Facades\Lang;

    Collection::macro('toLocale', function (string $locale) {
        return $this->map(function (string $value) use ($locale) {
            return Lang::get($value, [], $locale);
        });
    });

    $collection = collect(['first', 'second']);

    $translated = $collection->toLocale('es');

<a name="available-methods"></a>
[Laravel 11] Explain concurrency: Introduction

> [!WARNING]
> Laravel's Concurrency facade is currently in beta while we gather community feedback.

Sometimes you may need to execute several slow tasks which do not depend on one another. In many cases, significant performance improvements can be realized by executing the tasks concurrently. Laravel's Concurrency facade provides a simple, convenient API for executing closures concurrently.

<a name="concurrency-compatibility"></a>
[Laravel 11] Explain concurrency: How it Works

Laravel achieves concurrency by serializing the given closures and dispatching them to a hidden Artisan CLI command, which unserializes the closures and invokes it within its own PHP process. After the closure has been invoked, the resulting value is serialized back to the parent process.

The Concurrency facade supports three drivers: process (the default), fork, and sync. 

The fork driver offers improved performance compared to the default process driver, but it may only be used within PHP's CLI context, as PHP does not support forking during web requests. Before using the fork driver, you need to install the spatie/fork package:

The sync driver is primarily useful during testing when you want to disable all concurrency and simply execute the given closures in sequence within the parent process.

<a name="running-concurrent-tasks"></a>
[Laravel 11] Explain concurrency: Running Concurrent Tasks

To run concurrent tasks, you may invoke the Concurrency facade's run method. The run method accepts an array of closures which should be executed simultaneously in child PHP processes:

To use a specific driver, you may use the driver method:

Or, to change the default concurrency driver, you should publish the concurrency configuration file via the config:publish Artisan command and update the default option within the file:

<a name="deferring-concurrent-tasks"></a>
[Laravel 11] Explain configuration: The `about` Command

Laravel can display an overview of your application's configuration, drivers, and environment via the about Artisan command.

If you're only interested in a particular section of the application overview output, you may filter for that section using the --only option:

Or, to explore a specific configuration file's values in detail, you may use the config:show Artisan command:

<a name="environment-configuration"></a>
[Laravel 11] Explain configuration: Environment Configuration

It is often helpful to have different configuration values based on the environment where the application is running. For example, you may wish to use a different cache driver locally than you do on your production server.

To make this a cinch, Laravel utilizes the DotEnv PHP library. In a fresh Laravel installation, the root directory of your application will contain a .env.example file that defines many common environment variables. During the Laravel installation process, this file will automatically be copied to .env.

Laravel's default .env file contains some common configuration values that may differ based on whether your application is running locally or on a production web server. These values are then read by the configuration files within the config directory using Laravel's env function.

If you are developing with a team, you may wish to continue including and updating the .env.example file with your application. By putting placeholder values in the example configuration file, other developers on your team can clearly see which environment variables are needed to run your application.

> [!NOTE]  
> Any variable in your .env file can be overridden by external environment variables such as server-level or system-level environment variables.

<a name="environment-file-security"></a>
[Laravel 11] Explain configuration: Environment File Security

Your .env file should not be committed to your application's source control, since each developer / server using your application could require a different environment configuration. Furthermore, this would be a security risk in the event an intruder gains access to your source control repository, since any sensitive credentials would get exposed.

However, it is possible to encrypt your environment file using Laravel's built-in environment encryption. Encrypted environment files may be placed in source control safely.

<a name="additional-environment-files"></a>
[Laravel 11] Explain console tests: Success / Failure Expectations

To get started, let's explore how to make assertions regarding an Artisan command's exit code. To accomplish this, we will use the artisan method to invoke an Artisan command from our test. Then, we will use the assertExitCode method to assert that the command completed with a given exit code:

You may use the assertNotExitCode method to assert that the command did not exit with a given exit code:

    $this->artisan('inspire')->assertNotExitCode(1);

Of course, all terminal commands typically exit with a status code of 0 when they are successful and a non-zero exit code when they are not successful. Therefore, for convenience, you may utilize the assertSuccessful and assertFailed assertions to assert that a given command exited with a successful exit code or not:

    $this->artisan('inspire')->assertSuccessful();

    $this->artisan('inspire')->assertFailed();

<a name="input-output-expectations"></a>
[Laravel 11] Explain console tests: Input / Output Expectations

Laravel allows you to easily "mock" user input for your console commands using the expectsQuestion method. In addition, you may specify the exit code and text that you expect to be output by the console command using the assertExitCode and expectsOutput methods. For example, consider the following console command:

    Artisan::command('question', function () {
        $name = $this->ask('What is your name?');

        $language = $this->choice('Which language do you prefer?', [
            'PHP',
            'Ruby',
            'Python',
        ]);

        $this->line('Your name is '.$name.' and you prefer '.$language.'.');
    });

You may test this command with the following test:

If you are utilizing the search or multisearch functions provided by Laravel Prompts, you may use the expectsSearch assertion to mock the user's input, search results, and selection:

You may also assert that a console command does not generate any output using the doesntExpectOutput method:

The expectsOutputToContain and doesntExpectOutputToContain methods may be used to make assertions against a portion of the output:

<a name="confirmation-expectations"></a>
[Laravel 11] Explain console tests: Confirmation Expectations

When writing a command which expects confirmation in the form of a "yes" or "no" answer, you may utilize the expectsConfirmation method:

    $this->artisan('module:import')
        ->expectsConfirmation('Do you really wish to run this command?', 'no')
        ->assertExitCode(1);
