1. Clone, enter, and determine the path the application

git clone https://github.com/zhorton34/authorize-slim-4.git

cd authorize-slim-4

pwd

2. Copy output from pwd command (Full path to present working directory)

3. Open authorize-slim-4/homestead.yaml and update folders map path (Has comment next to it below)

ip: 192.168.10.10
memory: 2048
cpus: 2
provider: virtualbox
authorize: ~/.ssh/id_rsa.pub
keys:
    - ~/.ssh/id_rsa
folders:
    -
       # Replace `map: /Users/zhorton/tutorials/authorize-slim-4`
       # With `map: {the_copied_output_from_pwd_in_step_2}
        map: /Users/zhorton/tutorials/authorize-slim-4
        ## map Update with path you cloned the repository on your machine
        to: /home/vagrant/code
sites:
    -
        map: slim.auth
        to: /home/vagrant/code/public
databases:
    - slim
features:
    -
        mariadb: false
    -
        ohmyzsh: false
    -
        webdriver: false
name: authorize-slim-4
hostname: authorize-slim-4

4. Save and close homestead.yaml

5. Run vagrant up --provision to boot up your virtual machine

6. Once booted, open up your localmachine's host file (sudo vim /etc/hosts on linux or mac)

7. Add slim.auth

8. Boot up the vagrant virtual

  vagrant up --provision

9. Open your localmachines host file (sudo vim /etc/hosts on linux and mac)

10. Add slim.auth and the ip defined in the homestead.yaml (Example below, shouldn't need to change from example)

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost

###########################
# Homestead Sites (Slim 4)
###########################
192.168.10.10   slim.auth

11. Close and save hosts file

12. Test out http://slim.auth/ in your browser (Make sure vagrant has properly finished booting from step 8)

13. cd back into authorize-slim-4 within your terminal

14. Run vagrant ssh

15. Once ssh'd into your virtual machine, run

cd code && cp .env.example .env && composer install && npm install

Register Middleware

1. Create Middleware Class (Example: \App\Http\Middleware\RouteGuardMiddleware::class)
2. Open authorize-slim-4/app/Http/HttpKernel
3. Add \App\Http\Middleware\RouteGuardMiddleware::class to a specific route group or globally

class HttpKernel extends Kernel
{
    /**
     * Global Middleware
     *
     * @var array
     */
    public array $middleware = [
//        Middleware\ExampleAfterMiddleware::class,
//        Middleware\ExampleBeforeMiddleware::class
    ];

    /**
     * Route Group Middleware
     */
    public array $middlewareGroups = [
        'api' => [],
        'web' => [
            Middleware\RouteContextMiddleware::class,
            'csrf'
        ]
    ];
}

Create and Register new php slim command

1. Add new ExampleCommand.php File and class at app/console/commands/ExampleCommand.php
2. Define Command name, description, arguments, and handler within class

class ExampleCommand extends Command
{
    protected $name = 'example:command';
    protected $help = 'Example Command For Readme';
    protected $description = 'Example Command For Readme';

    public function arguments()
    {
        return [
            'hello' => $this->required('Description for this required command argument'),
            'world' => $this-optional('Description for this optional command argument', 'default')
        ];
    }

    public function handler()
    {
        /** Collect Console Input **/
        $all_arguments = $this->input->getArguments();
        $optional_argument = $this-input->getArgument('world');
        $required_argument = $this->input->getArgument('hello');

        /** Write Console Output **/
        $this->warning("warning output format");
        $this->info("Success output format");
        $this->comment("Comment output format");
        $this->error("Uh oh output format");
    }
}

3. Open app\console\ConsoleKernel.php
4. Add ExampleCommand::class to Registered Commands

<?php

namespace App\Console;

use Boot\Foundation\ConsoleKernel as Kernel;

class ConsoleKernel extends Kernel
{
    public array $commands = [
        Commands\ExampleCommand::class, // Registered example command
        Commands\ViewClearCommand::class,
        Commands\MakeSeederCommand::class,
        Commands\DatabaseRunSeeders::class,
        Commands\DatabaseFreshCommand::class,
        Commands\MakeMigrationCommand::class,
        Commands\DatabaseMigrateCommand::class,
        Commands\DatabaseTableDisplayCommand::class,
        Commands\DatabaseRollbackMigrationCommand::class
    ];
}

php slim make:{command} Scaffold Stub Generators

1. Available Generator Commands

  php slim make:command {ExampleConsoleCommand}      Generate Command Scaffold
  php slim make:controller {Example} description text for console command
  php slim make:factory {ExampleFactory}      Scaffold new factory command

2. Scaffold Generator Stubs (Dummy Files)

   • resources/stubs

3. Scaffold Configuration

   • config/stubs.php

Global Helper Functions

/*

• app_path
• dd (die and dump)
• throw_when

old($input_name)

• Used within blade to populate old input data when form validation fails

Example

<form>
  @csrf
  <input type='text' name='first_name' value='{{ old('first_name') }}' />
</form>

back()

• Redirect user back to previous page

Example

ExampleController 
{
   index()
   {
      return back();
   }
}

event()

• Set up events and event listeners

event()->listen('flash.success', fn ($message) => session()->flash()->add('success', $message);

event()->fire('flash.success', ['Way to go, it worked!']);

Alternatively, you can use the slim scaffold to set up event and listener classes php slim make:event ExampleEvent

• creates App/Events/ExampleEvent php slim make:listener ExampleListener
• create App/Listeners/ExampleListener

Register Class Event & Listeners in config/events.php

return [
   'events' => [
      ExampleEvent::class => [
          ExampleListener::class,
          ExampleListenerTwo::class,
          ExampleListenerThree::class
      ],
      ResetUserPasswordEvent::class => [
          GenerateResetPasswordKey::class,
          SendUserResetPasswordEmail::class,
      ]
   ]
];

Finally trigger the associated event

// Fire event using dependency injection
event()->fire(ExampleEvent::class);

// Fire event overriding default depency injections
event()->fire(ExampleEvent::class, [
   // parameterOne
   // parameterTwo
]);

session()

• Session (Using Syfony Session Component)

Example

// Flash to session to only remember for the proceeding request
session()->flash()->set('success', ['Successful Form Submission!']);
session()->flash()->set('errors', ['Name field failed', 'Email field failed']);

// Set directly to session to remember for several requests
session()->set('remember_in_session_for_multiple_requests', ['remember me']);

validator($input, $rules = [], $messages = [])

• Validator (Using Laravel Validators)

Example

$input = [
   'first_name' => 'John',
   'last_name' => 'Joe',
   'email' => '[email protected]'
];

$rules = [
   'first_name' => 'required|string',
   'last_name' => 'required|string|max:50',
   'email' => 'required|email|max:50|unique:users,email'
];

$messages = [
    'first_name.required' => 'First name is a required field',
    'first_name.string' => 'First name must be a string field',
    'last_name.required' => 'Last name must is a required field',
    'last_name.string' => 'Last name must be a string field',
    'email.email' => 'Email must be in the proper email format',
    'email.unique' => 'Email already taken, no duplicate emails allowed',
    'email.required' => 'Email is required',
];

$validation = validator($input, $rules, $messages);

if ($validation->fails()) {
   session()->flash()->set('errors', $validation->errors()->getMessages());
   
   return back();
}

if ($validation->passes() {
   session()->flash()->set('success', 'Successfully Submitted Form and Passed Validation');

   return redirect('/home');
}

Mailables (Send Emails)

1. @see \Boot\Foundation\Mail\Mailable Example

class ExampleController
{
   public function send(\Boot\Foundation\Mail\Mailable $mail, $response)
   {
       $user = \App\User::first();
       
       $success = $mail->view('mail.auth.reset', ['url' => 'https://google.com'])
            ->to($user->email, $user->first_name)
            ->from('[email protected]', 'Slim Authentication Admin')
            ->subject('Reset Password')
            ->send();

       $response->getBody()->write("Successfully sent Email: {$success}");

       return $response;
   }
}

Events (Events & associated listeners with dependency injection)

Example One

• Set up events and event listeners using the global event helper function NOTE: (This example show's an easy setup, but example two is considered better architecture)

// App\Providers\EventServiceProvider boot method()

event()->listen('flash.success', fn ($message) => session()->flash()->add('success', $message);

event()->fire('flash.success', [
   'Way to go, it worked!'
]);

Example Two: Event & Listener Classes

1. php slim make:event UserLogin
2. Open App/Events/UserLogin.php
3. Use the UserLogin.php event __construct to build or "construct" the event payload

<?php

namespace App\Events;

use App\Support\Auth;
use Boot\Foundation\Http\Session;

class ExampleEvent
{
    public $user;
    public $session;

    public function __construct(Session $session)
    {
        $this->user = Auth::user();
        $this->session = $session;

        return $this;
    }
}

4. php slim make:listener FlashWelcomeBackMessage
5. Open App/Listeners/FlashWelcomeBackMessage
6. Handle the event payload in the Listener __invoke method

<?php

namespace App\Listeners;

use App\Events\UserLogin;

class FlashWelcomeBackMessage
{
   public function __invoke(UserLogin $event)
   {
      $event->session->flash()->add('success', "Welcome Back {$event->user->first_name}!"); 
   }

}

Register Class Event & Listeners in config/events.php

return [
   'events' => [
      UserLogin::class => [
          FlashWelcomeBackMessage::class,
          // ExampleListenerTwo::class,
          // ExampleListenerThree::class
      ],
      // ResetUserPasswordEvent::class => [
           // GenerateResetPasswordKey::class,
           // SendUserResetPasswordEmail::class,
      // ]
   ]
];

Finally trigger event (Example: App\Http\Controllers\[email protected])

public function login(StoreLoginRequest $input)
{
  if ($input->failed()) return back(); 

  if (Auth::attempt($input->email, $input->password)) 
  {
      event()->fire(\App\Events\UserLogin::class); // Fire Event

      return redirect('/home');
   }

   return back();
}

Event Constructor and Listener Invoke Methods Support Dependency Injection // App\Http\[email protected]

// Example Using UserLogin Event:
// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$session = app()->resolve('session');
$different_user = \App\User::find(5); 

event()->fire(UserLogin::class, [
   $session, $different_user
]);

// Example Using Random Event
// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
event()->fire(ExampleEvent::class, [
   // parameterOne
   // parameterTwo
]);

// Dependency Injection With While Using event() to register listeners
// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
event()->listen('welcome-view', fn (\Jessengers\Blade\Blade $blade) => $blade->make('welcome')->render());

// Fire's event. Listeners will work using the blade instance resolved from our service container
event()->fire('welcome-view');

// inject blade instance with different template path than the one binded to our container
event()->fire('welcome-view', [
    new \Jessengers\Blade\Blade(
        base_path('vendor/package/resources/views'), 
        storage_path('cache'),
    )
]);
