Installation

You can install the package via Composer:

composer require internetguru/laravel-common

The CommonServiceProvider is auto-discovered via composer.json extra.laravel.providers. No manual registration is needed for the core provider.

Run Tests Locally

To run the tests manually, you can use the following command:

./test.sh

Service Providers

CommonServiceProvider

Auto-registered via package discovery. It provides:

Custom exception handler registration.
Loading of package routes, views (ig-common namespace), translations, and Blade components (ig namespace).
Registration of the Livewire Messages component.
Listener for mail logging (NotificationSent event).
Registration of the ulid32 validation rule.
Registration of all helper macros (String, Number, Carbon).
Automatic registration of all middleware into the web middleware group.
Queue connection safety check — throws an exception at boot if the queue connection is set to sync (except during unit tests).

ReadOnlyServiceProvider

Intercepts all write database queries and throws DbReadOnlyException when config('app.readonly') is true.

Read-only operations (SELECT, SHOW, DESCRIBE, EXPLAIN, PRAGMA) are always allowed. Queries targeting sessions, token_auths, mail_logs, users, and socialites tables are whitelisted.

To use, register the provider in your config/app.php:

'providers' => ServiceProvider::defaultProviders()->merge([
    InternetGuru\LaravelCommon\ReadOnlyServiceProvider::class,
])->toArray(),

Then set readonly to true in config/app.php (or via environment variable) to activate read-only mode.

TranslationServiceProvider

Logs missing translations and translation variables in the current language. Throws an exception when not in production environment. In debug mode, checks all available languages.

Logs warning when a translation key is missing or a variable required in a translation string is not provided.
Checks all languages in debug mode from all available locales.
Throws exception InternetGuru\LaravelCommon\Exceptions\TranslatorException instead of logging when the app is not in production mode.

To use the provider, replace the default TranslationServiceProvider in config/app.php:

use Illuminate\Support\ServiceProvider;

'providers' => ServiceProvider::defaultProviders()->replace([
    Illuminate\Translation\TranslationServiceProvider::class => InternetGuru\LaravelCommon\TranslationServiceProvider::class,
])->toArray(),

Middleware

All middleware listed below is automatically registered in the web middleware group by the CommonServiceProvider. No manual registration is needed.

To bypass a specific middleware on a route, use the withoutMiddleware method:

Route::get('/example', ExampleController::class)
    ->withoutMiddleware(\InternetGuru\LaravelCommon\Http\Middleware\PreventDuplicateSubmissions::class);

`CheckPostItemNames` Middleware

Checks for invalid POST parameter names containing dots ".". Helps prevent issues with Laravel's input handling. Throws an exception in non-production environments and logs a warning in production.

Example:

When a POST request contains parameter names with dots:

POST /submit-form
Content-Type: application/x-www-form-urlencoded

username=johndoe&user.email=johndoe@example.com

In Non-Production Environments: The middleware will throw an HTTP 400 exception:
```
Invalid POST parameter names containing dots: user.email
```

In Production Environment: The middleware will log a warning:

[WARNING] Invalid POST parameter names containing dots: user.email

`InjectUmamiScript` Middleware

Automatically injects the Umami analytics tracking script into HTML responses when UMAMI_WEBSITE_ID is set.

The script is injected before the closing </head> tag. Set the following environment variables to enable:

Variable	Description	Default
`UMAMI_WEBSITE_ID`	Your Umami website ID (required to enable tracking).	`''` (disabled)
`UMAMI_SRC`	URL to the Umami tracking script.	`https://umami.internetguru.io/script.js`

Example .env:

UMAMI_WEBSITE_ID=0d38f931-afdc-4a99-a913-5c601fc95629

The injected script:

<script defer src="https://umami.internetguru.io/script.js" data-website-id="0d38f931-afdc-4a99-a913-5c601fc95629"></script>

`PreventDuplicateSubmissions` Middleware

Prevents duplicate POST form submissions by caching a hashed request fingerprint (IP + path + input minus reCAPTCHA) for 1 minute. Livewire update requests are excluded.

When a duplicate submission is detected, the user is redirected back with input and an error message.

`SetPrevPage` Middleware

Tracks the current and previous page URLs in the session for GET requests. Used internally by the exception handler to redirect users back to meaningful pages on errors.

Ignores AJAX requests and image (img/*) requests. Prevents tracking the same URL consecutively.

`TimezoneMiddleware`

Detects the user's timezone via IP geolocation and stores it in the session as display_timezone.

Uses the GeolocationService to resolve the IP address. Falls back to config('geoip.default_location.timezone') on failure. Resolves only once per session.

`VerifyCsrfToken`

Extends Laravel's CSRF verification with HMAC-based request signature verification. Requests containing a valid X-Signature and X-Timestamp header pair bypass CSRF checks. Livewire routes are also excluded by default.

The signature is validated using the app key with a 60-second freshness window.

Helper Methods

The Helpers class provides useful static methods for Laravel applications.

Configuration and example usage:

Add the following lines to config/app.php:

use Illuminate\Support\Facades\Facade;

'aliases' => Facade::defaultAliases()->merge([
    'Helpers' => InternetGuru\LaravelCommon\Support\Helpers::class,
])->toArray(),

Use Helpers class methods in your application:

<meta name="generator" content="{{ Helpers::getAppInfo() }}"/>

Available methods:

Method	Description
`getAppInfoArray()`	Returns app name, environment, version, git branch, and commit as an array.
`getAppInfo()`	Returns app info as a single string.
`parseUrlPath($homeRoute, $skipFirst)`	Parses the current URL path into breadcrumb segments with translations.
`createTitle($separator, $homeRoute)`	Generates a page title from breadcrumb segments (reversed, separated).
`getEmailClientLink()`	Returns a link to the Mailpit inbox when using Mailpit mailer.
`verifyRequestSignature(Request $request)`	Verifies HMAC-SHA256 request signature (`X-Signature` + `X-Timestamp` headers).

For full implementation details, see the Helpers class.

Helper Macros

The package registers a set of useful macros for Str, Carbon, and Number. See macros.php for the complete list.

String Macros

Macro	Description
`Str::ref($length)`	Generates a random alphanumeric reference code (excludes ambiguous characters `i`, `l`, `o`, `0`, `1`, `u`). Starts with a letter and contains at least one digit.

Number Macros

Macro	Description
`Number::currencyForHumans($number, $in, $precision)`	Formats a number as a locale-aware currency string. Returns the currency symbol if no number is provided.
`Number::formatCurrencyToInput($number, $in, $precision, $inputTemplate)`	Formats a number for use inside an input field with a currency symbol.

Carbon Macros

Macro	Description
`$date->dateForHumans()`	Locale-aware date (`L` format).
`$date->dateTimeForHumans()`	Locale-aware date and time (`L LT` format).
`$date->myDiffForHumans()`	Human-readable time difference with "just now" for <60 seconds and "1 year" normalization.
`$date->timeForHumans()`	Clean time format (removes leading zeros and `:00`).
`$date->randomWorkTime($from, $to)`	Sets a random time during work hours (default 9–17).

Example usage:

use Carbon\Carbon;
use Illuminate\Support\Facades\Number;
use Illuminate\Support\Str;

echo Str::ref(6);
// Output: "k3mhpq"

Number::useCurrency('USD');
echo Number::currencyForHumans(1234);
// Output (en_US locale): $1,234
echo Number::currencyForHumans();
// Output (en_US locale): $
echo Number::currencyForHumans(1234.567, in: 'EUR', precision: 2);
// Output (en_US locale): €1,234.57

$date = Carbon::parse('2023-12-31');
echo $date->dateForHumans();
// Output (en_US locale): 12/31/2023
$dateTime = Carbon::parse('2023-12-31 18:30:00');
echo $dateTime->dateTimeForHumans();
// Output (en_US locale): 12/31/2023 6:30 PM

Blade Components

All Blade components are registered under the ig namespace and can be used with <x-ig::component-name />.

Breadcrumb Blade Component

Renders breadcrumb navigation based on routes matching the current URL segments. Supports translations with short and long labels, custom divider, and segment skipping.

Key Features:

Customizable Divider – Allows a custom divider symbol between breadcrumb items.
Short and Long Labels – Using trans_choice if available shows n-th right translation based on the item position.
Segment Skipping – Skips a specified number of URL segments. Useful for nested routes or routes with prefixes (e.g. language).
Skip Prefixes – Routes whose URI starts with a configured prefix are treated as error pages (no breadcrumb generated), preventing missing translation warnings. Configured via breadcrumb_skip_prefixes in config/ig-common.php:
```
'breadcrumb_skip_prefixes' => [
    '_debugbar',
    '_ignition',
    'livewire',
    'storage',
    'telescope',
    'horizon',
],
```

Usage:

<!-- By default, this will generate breadcrumb items based on the current URL path. -->
<x-ig::breadcrumb/>
<!-- You can change the divider symbol by setting the divider attribute -->
<x-ig::breadcrumb divider="|" />
<!-- If you need to skip certain segments of the URL (e.g., a language prefix), use the skipFirst attribute -->
<x-ig::breadcrumb :skipFirst="1" />

Example:

Assuming you have the following routes defined:

<?php
Route::get('/', function () {
    // ...
})->name('home');

Route::get('/products', function () {
    // ...
})->name('products.index');

Route::get('/products/{product}', function ($product) {
    // ...
})->name('products.show');

And your translation files (resources/lang/en/navig.php) include:

<?php
return [
    'home' => 'Long Application Name|LAN',
    'products.index' => 'All Products|Products',
    'products.show' => 'Product Details',
];

When you visit the /products/123 URL, the short translation will be used for the home and products.index routes.
```
LAN > Products > Product Details
```
When you visit the /products URL, the short label will be used for the home route.
```
LAN > All Products
```
When you visit the / URL, the long label will be used for the home route.
```
Long Application Name
```

System Messages (Livewire Component)

Renders system temporary success messages and persistent error messages in different colors, with a close button. Powered by Livewire.

The component automatically picks up session success and errors data. You can also send messages dynamically via Livewire events.

Include the component in your Blade template:

<livewire:ig-messages />

Dispatching messages from other Livewire components:

$this->dispatch('ig-message', type: 'success', message: 'Item saved!');
$this->dispatch('ig-message', type: 'danger', message: 'Something went wrong.');

Form Blade Components

The package provides a set of Blade components for forms and various input types.

Notes:

The Google reCAPTCHA V3 service is enabled by default. To disable it, set the recaptcha attribute to false.

Complete example:

<x-ig::form action="route('test')" :recaptcha="false">
    <x-ig::input type="text" name="name" required>Name</x-ig::input>
    <x-ig::input type="option" name="simple-options" :value="['a', 'b', 'c']">Simple Options</x-ig::input>
    <x-ig::input type="option" name="advanced-options" :value="[
        ['id' => '1', 'value' => 'User 1' ],
        ['id' => '2', 'value' => 'User 2' ],
        ['id' => '3', 'value' => 'User 3' ],
    ]">Advanced Options</x-ig::input>
    <x-ig::input type="checkbox" name="checkbox" value="1">Checkbox</x-ig::input>
    <x-ig::input type="radio" name="radio" value="1">Radio</x-ig::input>
    <x-ig::input type="textarea" name="description">Description</x-ig::input>
    <x-ig::submit>Submit Form</x-ig::submit>
</x-ig::form>

Language Switch Blade Component

Renders a language switcher as a list of links with the current language highlighted.

<x-ig::lang-switch />

Print Button Blade Component

Renders a print button that triggers the browser's print dialog.

<x-ig::print-button />

Footer Copy Blade Component

Renders a copyright footer with provider information and year range.

<x-ig::footer-copy />

Demo Info Blade Component

Renders a demo mode warning banner informing users that displayed information is illustrative and may reset.

<x-ig::demo-info />

Read-Only Mode Info Blade Component

Renders an informational banner indicating the application is in read-only mode and editing is disabled.

<x-ig::read-only-mode-info />

Email Feedback Blade Component

Renders a technical support email link with pre-filled subject and diagnostic data.

<x-ig::email-feedback />

Editable Blade Component

Provides an Alpine.js editable data component for inline editing functionality.

<x-ig::editable />

Casts

CarbonIntervalCast

Casts a string to a CarbonInterval and back. Uses CarbonInterval::fromString() to parse and forHumans() (in English locale) to serialize.

use Illuminate\Database\Eloquent\Model;
use InternetGuru\LaravelCommon\Casts\CarbonIntervalCast;

class Task extends Model
{
    protected $casts = [
        'duration' => CarbonIntervalCast::class,
    ];
}

Traits

Ulid32 Trait

Provides ULID (Crockford Base32) utility methods for Eloquent models. Generates 26-character Base32-encoded UUIDs and adds human-readable formatting, URL generation, and link rendering.

use InternetGuru\LaravelCommon\Traits\Ulid32;

class Order extends Model
{
    use Ulid32;
}

Available methods:

Method	Description
`$model->ulidForHumans()`	Formats the ULID with dashes (e.g. `01JM-ABCDEF-GHIJKL-MNOPQR-STUV`).
`$model->shortUlidForHumans()`	Returns the last 7 characters of the formatted ULID.
`$model->ulidUrl($usp)`	Generates a URL to the model's `show` route.
`$model->ulidLink($content)`	Renders an HTML link to the model.
`Model::generateBase32Uuid()`	Generates a new Crockford Base32-encoded UUID (26 characters).

Rules

Ulid32 Validation Rule

Validates that a value is a valid 26-character Crockford Base32 ULID (no I, L, O, U characters).

Can be used as a class-based rule or via the globally registered ulid32 rule:

// Class-based
use InternetGuru\LaravelCommon\Rules\Ulid32;

$request->validate([
    'code' => ['required', new Ulid32],
]);

// String-based (registered globally by CommonServiceProvider)
$request->validate([
    'code' => 'required|ulid32',
]);

Services

GeolocationService

Resolves an IP address to a geographic location using the torann/geoip package. Results are cached and rate-limited (5 lookups per 60 seconds).

use InternetGuru\LaravelCommon\Services\GeolocationService;

$geoService = app(GeolocationService::class);
$location = $geoService->getLocation('8.8.8.8');

echo $location->timezone; // "America/Chicago"
echo $location->country;  // "US"

Throws GeolocationServiceException on failure or rate limit.

Notifications

BaseNotification

Abstract queued notification class that captures request context (IP, timezone, user ID, URL) at creation time and sends via the mail channel.

Features:

Queued with 10 retries and 2-minute backoff.
Retry middleware via LogNotificationFailure — logs warnings on transient failures.
Captures the sender's IP, timezone (via geolocation), authenticated user ID, and current page URL.
Logs permanently failed notifications.

Extend this class to create your own notifications:

use InternetGuru\LaravelCommon\Notifications\BaseNotification;

class OrderConfirmation extends BaseNotification
{
    public function toMail(object $notifiable): MailMessage
    {
        return (new \InternetGuru\LaravelCommon\Mail\MailMessage)
            ->setExtraMailData($this->getExtraMailData())
            ->subject('Order Confirmed')
            ->view(['html' => 'emails.order-confirmed', 'text' => 'emails.order-confirmed-text']);
    }
}

MailMessage

Extends Laravel's MailMessage with automatic reference number generation, no-reply detection, and extra mail data injection.

Features:

Appends a random reference code (Ref XXXXX) to every subject line for tracking.
Automatically detects no-reply addresses and adds a "replies not delivered" note.
Supports arbitrary extra data (setExtraMailData) passed to email views (IP, timezone, user ID, etc.).

Mail Logging

All sent mail notifications are automatically logged to the mail_logs database table via the LogSentNotification listener.

Publish the migration to create the mail_logs table:

php artisan vendor:publish --tag=ig-common:migrations
php artisan migrate

Logged fields: to, replyto, subject, body, created_at, updated_at.

Exception Handling

The package registers a custom exception handler that provides user-friendly error pages and JSON responses for common HTTP errors (401, 402, 403, 404, 419, 429, 500, 503).

Features:

Read-only mode: DbReadOnlyException returns a 503 response (JSON or redirect with error).
Connection errors: ConnectException returns a friendly error message.
Rate limiting (429) and session expiration (419): Handled with translated messages.
Debug mode: Uses dd() for detailed exception inspection.
JSON support: Returns JSON responses when the request expects JSON.
Redirects to the previously tracked page (via SetPrevPage middleware) on error.

Custom error views are included for standard HTTP status codes. The error pages use the ig-common::layouts.base layout.

Logging

JsonDailyLogger

A custom Monolog logger that writes JSON-formatted daily rotating log files enriched with request context.

Each log entry includes:

User info: ID, name, email (if authenticated).
Request input: All inputs except password, _token, and g-recaptcha-response. Livewire snapshot data is stripped.
Session ID.
App info: Git branch and commit.
Request info: URL, IP, HTTP method, server, referrer, user agent.

Configuration in config/logging.php:

'channels' => [
    'json_daily' => [
        'driver' => 'custom',
        'via' => InternetGuru\LaravelCommon\Logging\JsonDailyLogger::class,
        'path' => storage_path('logs/app.log'),
        'days' => 14,
        'level' => 'debug',
    ],
],

Localization

The package includes translations in English (en), Czech (cs), and Danish (da) for:

Error pages (errors.php) – HTTP status messages and descriptions.
Layout strings (layouts.php) – Footer, email templates, support links, and UI labels.
System messages (messages.php) – Validation messages, email labels, and demo mode warnings.
Navigation (navig.php) – Breadcrumb labels for routes.
