MagicLink for Laravels App

Through the MagicLink class we can create a secure link that later being visited will perform certain actions, which will allow us offer secure content and even log in to the application.

Installation

You can install this package via composer using:

composer require cesargb/laravel-magiclink

You can publish migration with command:

php artisan vendor:publish --provider="MagicLink\MagicLinkServiceProvider" --tag=migrations

After the migration has been published you can create the table by running the migrations:

php artisan migrate

Note: If you have the version 1 installed, read this.

Use case

With this example you can create a link to auto login on your application with the desired user:

use MagicLink\Actions\LoginAction;
use MagicLink\MagicLink;

$urlToAutoLogin =  MagicLink::create(new LoginAction($user))->url

Create a MagicLink

The MagicLink class has the create method to generate a class that through the url property we will obtain the link that we will send to our visitor.

This method requires the action to be performed.

Actions

Each MagicLink is associated with an action, which is what will be performed once the link is visited.

• Login Action
• Download file Action
• View Action
• Http Reponse Action

Login Action

Through the LoginAction action, you can log in to the application using the generated link by MagicLink.

Your constructor supports the user who will login. Optionally we can specify the HTTP response using the $httpResponse argument and specify the $guard.

Examples:

use MagicLink\Actions\LoginAction;
use MagicLink\MagicLink;

// Sample 1; Login and redirect to dash board
$urlToDashBoard = MagicLink::create(
    new LoginAction(User::first(), redirect('/dashboard'))
)->url;

// Sample 2; Login and view forms to password reset and use guard web
$urlShowView = MagicLink::create(
    new LoginAction(
        User::first(),
        view('password.reset', ['email' => '[email protected]'])
    )
)->url;

// Sample 3; Login in other guard and redirect default
$urlShowView = MagicLink::create(
    new LoginAction(
        User::first(),
        null,
        'otherguard'
    )
)->url;

Download file Action

This action, DownloadFileAction, permit create a link to download a private file.

The constructor require the file path.

Example:

use MagicLink\Actions\DownloadFileAction;
use MagicLink\MagicLink;

// Url to download the file storage_app('private_document.pdf')
$url = MagicLink::create(new DownloadFileAction('private_document.pdf'))->url;

View Action

With the action ViewAction, you can provide access to the view. You can use in his constructor the same arguments than method view of Laravel.

Example:

use MagicLink\Actions\ViewAction;
use MagicLink\MagicLink;

// Url to view a internal.blade.php
$url = MagicLink::create(new ViewAction('internal', [
    'data' => 'Your private custom content',
]))->url;

Http Response Action

Through the ResponseAction action we can access private content without need login. Its constructor accepts as argument the HTTP response which will be the response of the request.

Examples:

use MagicLink\Actions\ResponseAction;
use MagicLink\MagicLink;

$urlToCustomFunction = MagicLink::create(
    new ResponseAction(function () {
        Auth::login(User::first());

        return redirect('/change_password');
    })
)->url;

MagicLink link lifetime

By default a link will be available for 72 hours after your creation. We can modify the life time in minutes of the link by the $lifetime option available in the create method. This argument accepts the value null so that it does not expire in time.

$lifetime = 60; // 60 minutes

$magiclink = MagicLink::create(new ResponseAction(), $lifetime);

$urlToSend = $magiclink->url;

We also have another option $numMaxVisits, with which we can define the number of times the link can be visited, null by default indicates that there are no visit limits.

$lifetime = null; // not expired in the time
$numMaxVisits = 1; // Only can visit one time

$magiclink = MagicLink::create(new ResponseAction(), $lifetime, $numMaxVisits);

$urlToSend = $magiclink->url;

Events

MagicLink fires two events:

• MagicLink\Events\MagicLinkWasCreated
• MagicLink\Events\MagicLinkWasVisited
