Fusecore

FuseCore Modular Architecture

Agent Workflow (MANDATORY)

Before ANY implementation in FuseCore project, use TeamCreate to spawn 3 agents:

1. fuse-ai-pilot:explore-codebase - Analyze existing modules in /FuseCore/
2. fuse-ai-pilot:research-expert - Verify Laravel 13 patterns via Context7
3. fuse-laravel:laravel-expert - Apply Laravel best practices

After implementation, run fuse-ai-pilot:sniper for validation.

Overview

FuseCore is a Modular Monolith architecture for Laravel 13 with React 19 integration.

Component	Purpose
Module	Self-contained feature (User, Dashboard, Blog)
Auto-Discovery	Automatic registration via module.json
Traits	HasModule for resource loading
Contracts	ModuleInterface, ReactModuleInterface
React Integration	Isolated React per module
i18n	Multi-language support (FR/EN/DE/IT/ES)

---

Critical Rules

1. All code in /FuseCore/{Module}/ - Never in /app/
2. One module.json per module - Required for discovery
3. ServiceProvider per module - Use HasModule trait
4. Files < 100 lines - Split at 90 lines (SOLID)
5. Interfaces in /App/Contracts/ - Never in components
6. Migrations in module - /Database/Migrations/
7. Routes in module - /Routes/api.php

Quick Reference

Create New Module

# 1. Create directory structure
mkdir -p FuseCore/{ModuleName}/{App/{Models,Http/Controllers,Services,Providers},Database/Migrations,Resources/React,Routes}

# 2. Create module.json
# 3. Create ServiceProvider with HasModule trait
# 4. Create routes/api.php
# 5. Run: php artisan fusecore:cache-clear

module.json

{
    "name": "ModuleName",
    "version": "1.0.0",
    "enabled": true,
    "isCore": false,
    "dependencies": ["User"]
}

ServiceProvider

class ModuleNameServiceProvider extends ServiceProvider
{
    use HasModule;

    public function boot(): void
    {
        $this->loadModuleMigrations();
    }
}

Routes

Route::middleware(['api', 'auth:sanctum'])->group(function () {
    Route::apiResource('items', ItemController::class);
});

---

Module Checklist

• /FuseCore/{Module}/ directory created
• module.json with name, version, dependencies
• {Module}ServiceProvider.php with HasModule trait
• Routes in /Routes/api.php
• Migrations in /Database/Migrations/
• Models in /App/Models/
• Controllers in /App/Http/Controllers/
• React in /Resources/React/ (if needed)
• i18n in /Resources/React/i18n/locales/

---

SOLID Compliance

Rule	FuseCore Implementation
Single Responsibility	One module = one feature
Open/Closed	Extend via ModuleInterface
Liskov Substitution	ReactModuleInterface extends ModuleInterface
Interface Segregation	Separate contracts
Dependency Inversion	Inject via ServiceProvider

File limits: All files < 100 lines. Split at 90.

---

Naming Conventions

Type	Convention	Example
Module folder	PascalCase	BlogPost
module.json name	PascalCase	"name": "BlogPost"
ServiceProvider	{Module}ServiceProvider	BlogPostServiceProvider
Controller	{Resource}Controller	PostController
Model	Singular	Post
Migration	create_{table}_table	create_posts_table
Routes file	api.php	Always api.php

Laravel 13 Notes

Stack FuseCore L13

• Laravel 13.0 + PHP 8.3 minimum
• React 19 + TypeScript 5.8 (côté frontend module)
• Inertia 2 pour le bridge React ↔ modules

Module ServiceProvider et L13

new Model() dans register() est désormais interdit (LogicException). Toute instanciation Eloquent doit migrer dans boot().

public function register(): void
{
    $this->app->bind(PostRepositoryContract::class, EloquentPostRepository::class);
    // NE PAS faire : $defaults = new Post(); ← LogicException en L13
}

public function boot(): void
{
    Post::observe(PostObserver::class);
}

Cache prefixes par module

L13 utilise hyphens par défaut. Pour FuseCore, configurer le préfixe par module via module.json reste compatible :

{
  "name": "BlogPost",
  "cache_prefix": "blogpost-"
}

Best Practices

DO

• Créer un module = un dossier FuseCore/<Module>/ complet (Contracts/, Services/, Http/, Models/)
• Déclarer toutes les dépendances inter-modules via Contracts (jamais classes concrètes)
• Utiliser final readonly class pour DTOs de module (PHP 8.3+)
• Migrer toute logique Model du register() vers boot()
• Préférer Inertia 2 + React 19 pour les modules avec UI

DON'T

• Importer une classe d'un autre module sans passer par son Contract
• Mettre la logique métier dans Controllers (extraire en Service du module)
• Instancier un modèle Eloquent dans register() (LogicException L13)
• Dépasser 100 lignes par fichier (splitter en sous-modules ou Services)
• Partager des migrations entre modules (chaque module possède ses tables)
