SOLID Principles in Laravel: A Cyberpunk AI Guide, Part 1

Part 1: The Single Responsibility Principle

It’s a dark and stormy night in the neon-lit streets of a cyberpunk city. Code is the currency that keeps the city running. But as the lines between man and machine continue to blur, it’s more important than ever to have a strong foundation in software design principles. That’s where SOLID principles come in.

In this series of articles, we’ll be taking a deep dive into the world of Laravel, a popular PHP framework. We’ll explore how the SOLID principles can help us build more maintainable, scalable, and effective applications in this cyberpunk era.

Starting with the single responsibility principle (SRP), it states that a class should have only one reason to change (or that a class should only have one responsibility).

Imagine you’re building an AI assistant for a group of hackers. The AI has several tasks it needs to perform, including:

  1. Scanning the dark web for information about upcoming cyber attacks
  2. Analyzing the data to identify patterns and predict potential targets
  3. Sending alerts to the hackers when a potential target is identified
  4. Monitoring the hackers’ progress on each case and providing assistance as needed

To follow SRP, design the AI so that each of these tasks is handled by a separate module. This way, each module has a clear, specific purpose and is responsible for only one aspect of the AI’s overall function.

The module responsible for scanning the dark web would be responsible only for that task, and shouldn’t have to be concerned about analyzing the data or sending alerts. The module responsible for analyzing the data would be focused only on that task, and wouldn’t need to concern itself with the other tasks. This helps to keep the code organized and maintainable, as each module can be modified or updated independently without affecting the other modules.

In this way, the SRP helps to ensure that the AI is flexible and scalable, and that each component of the system is easy to understand and modify.

Implementation:

Models

First, you would need to create a few models to represent the various components of the AI. For example, you might have a Scan model to represent the process of scanning the dark web for information, a DataAnalysis model to represent the process of analyzing the data, and a Alert model to represent the process of sending alerts to the hackers.

Controllers

Next, you would create some controllers to handle the various tasks that the AI needs to perform:

<?php

namespace App\Http\Controllers;

use App\Scan;
use App\DataAnalysis;
use App\Alert;
use Illuminate\Http\Request;

class ScanController extends Controller
{
    public function scanDarkWeb()
    {
        // Scan the dark web
    }
}

class DataAnalysisController extends Controller
{
    public function analyzeData()
    {
        // Analyze the data
    }
}

class AlertController extends Controller
{
    public function sendAlerts()
    {
        // Send alerts
    }
}

class ProgressController extends Controller
{
    public function monitorProgress()
    {
        // Monitor the hackers' progress
    }
}

Each task is handled by a separate controller, with a single action in each controller. This helps to ensure that each controller has a clear, specific purpose and is responsible for only one aspect of the AI’s overall function, following the SRP.

Routes

Next we set up routes to the appropriate actions in each controller. For example, you would have a route that maps the URL /scan to the scanDarkWeb action in the ScanController, and a route that maps the URL /analyze to the analyzeData action in the DataAnalysisController, etc.

Route::get('/scan', [ScanController::class, 'scanDarkWeb']);

Scheduler

You could use a task scheduler (such as Laravel’s built-in Task Scheduling) to run the various actions at regular intervals. For example, you might want to scan the dark web every hour, analyze the data every day, and send alerts as needed:

$schedule->call(function () {
    (new ScanController)->scanDarkWeb();
})->hourly();

$schedule->call(function () {
    (new DataAnalysisController)->analyzeData();
})->daily();

$schedule->call(function () {
    (new AlertController)->sendAlerts();
})->when(function () {
    // Determine when to send alerts
});

$schedule->call(function () {
    (new ProgressController)->monitorProgress();
})->everyFiveMinutes();
