FuseCore Modular Architecture

Agent Workflow (MANDATORY)

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

•fuse-ai-pilot:explore-codebase - Analyze existing modules in /FuseCore/
•fuse-ai-pilot:research-expert - Verify Laravel 12 patterns via Context7
•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 12 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

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

Quick Reference

Create New Module

bash

# 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

json

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

ServiceProvider

php

class ModuleNameServiceProvider extends ServiceProvider
{
    use HasModule;

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

Routes

php

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`
