Creating notifications in Laravel

Introduction

Notifications help you send messages to users about important events. They keep users informed without needing them to check manually.

When you want to alert a user about a new message or comment.

When you need to inform users about system updates or maintenance.

To notify users about successful or failed actions, like order confirmation.

When sending reminders for upcoming events or deadlines.

To alert admins about critical system errors or user reports.

Syntax

Laravel

php artisan make:notification NotificationName

// In the notification class:
public function via($notifiable)
{
    return ['mail', 'database'];
}

public function toMail($notifiable)
{
    return (new MailMessage)
        ->line('Notification message')
        ->action('Notification Action', url('/'))
        ->line('Thank you!');
}

public function toArray($notifiable)
{
    return [
        'data' => 'Notification data here',
    ];
}

Use php artisan make:notification to create a new notification class.

The via method defines how the notification is sent (mail, database, etc.).

Examples

This sends the notification only by email.

Laravel

public function via($notifiable)
{
    return ['mail'];
}

This stores the notification in the database for later display.

Laravel

public function via($notifiable)
{
    return ['database'];
}

This defines the data saved in the database notification.

Laravel

public function toArray($notifiable)
{
    return [
        'message' => 'You have a new friend request!'
    ];
}

Sample Program

This notification sends a welcome email to a new user with a link to the dashboard.

Laravel

<?php

namespace App\Notifications;

use Illuminate\Notifications\Notification;
use Illuminate\Notifications\Messages\MailMessage;

class WelcomeUser extends Notification
{
    public function via($notifiable)
    {
        return ['mail'];
    }

    public function toMail($notifiable)
    {
        return (new MailMessage)
            ->subject('Welcome to Our App')
            ->line('Hello! Thanks for joining us.')
            ->action('Visit Dashboard', url('/dashboard'))
            ->line('We hope you enjoy your stay.');
    }
}

// Usage example in a controller or event:
// $user->notify(new WelcomeUser());

Important Notes

Notifications can be sent via multiple channels like mail, database, SMS, or Slack.

Make sure to configure mail settings in .env to send emails.

Database notifications require a notifications table created by php artisan notifications:table and migration.

Summary

Notifications keep users informed about important events.

Create notifications with php artisan make:notification and define delivery channels.

Use notify() on user models to send notifications.
