Perform Self-Diagnosis Tests On Your Laravel Application

Latest Version on Packagist Build Status Quality Score Total Downloads

This package allows you to run self-diagnosis tests on your Laravel application. It comes with multiple checks out of the box and allows you to add custom checks yourself.

Here is an example output of the command:

All Checks passed

Included checks

  • Is the APP_KEY set?
  • Are your composer dependencies up to date with the composer.lock file?
  • Do you have the correct PHP version installed?
  • Do you have the correct PHP extensions installed?
  • Can a connection to the database be established?
  • Do the storage and bootstrap/cache directories have the correct permissions?
  • Does the .env file exist?
  • Is the maintenance mode disabled?
  • Are the required locales installed on the system?
  • Are there environment variables that exist in .env.example but not in .env?
  • Are there any migrations that need to be run?
  • Is the storage directory linked?
  • Can Redis be accessed?

Development environment checks

  • Is the configuration not cached?
  • Are the routes not cached?
  • Are there environment variables that exist in .env but not in .env.example?

Production environment checks

  • Is the configuration cached?
  • Are the routes cached?
  • Is the xdebug PHP extension disabled?
  • Is APP_DEBUG set to false?
  • Are certain servers reachable?
  • Are certain supervisor programs running?

Installation

You can install the package via composer:

composer require beyondcode/laravel-self-diagnosis

If you're using Laravel 5.5+ the SelfDiagnosisServiceProvider will be automatically registered for you.

Usage

Just call the artisan command to start the checks:

php artisan self-diagnosis

Customization

You can publish the configuration file, that contains all available checks using:

php artisan vendor:publish --provider=BeyondCode\\SelfDiagnosis\\SelfDiagnosisServiceProvider

This will publish a self-diagnosis.php file in your config folder. This file contains all the checks that will be performed on your application.

Available Configuration Options

The following options are available for the individual checks:

Custom Checks

You can create custom checks, by implementing the BeyondCode\SelfDiagnosis\Checks\Check interface and adding the class to the config file. Like this:

<?php

use BeyondCode\SelfDiagnosis\Checks\Check;

class MyCustomCheck implements Check
{
    /**
     * The name of the check.
     *
     * @param array $config
     * @return string
     */
    public function name(array $config): string
    {
        return 'My custom check.';
    }

    /**
     * Perform the actual verification of this check.
     *
     * @param array $config
     * @return bool
     */
    public function check(array $config): bool
    {
        return true;
    }

    /**
     * The error message to display in case the check does not pass.
     *
     * @param array $config
     * @return string
     */
    public function message(array $config): string
    {
        return 'This is the error message that users see if "check" returns false.';
    }
}
