Configuration

Root composer.json:

{
    "autoload": {
        "psr-4": {
            "App\\": "app/",
            "App\\Modules\\": "app/Modules",
            "Database\\Factories\\": "database/factories/",
            "Database\\Seeders\\": "database/seeders/"
        }
    },
    "extra": {
        "laravel": {
            "dont-discover": []
        },
        "merge-plugin": {
            "include": [
                "app/Modules/*/composer.json"
            ]
        }
    }
}

app/Modules/Platform/composer.json:

{
//...
    "autoload": {
        "psr-4": {
            "App\\Modules\\Platform\\": "app/",
            "App\\Modules\\Platform\\Database\\Factories\\": "database/factories/",
            "App\\Modules\\Platform\\Database\\Seeders\\": "database/seeders/"
        }
    },
    "autoload-dev": {
        "psr-4": {
            "App\\Modules\\Platform\\Tests\\": "tests/"
        }
    }
}

'paths' => [
    'modules' => base_path('app/Modules'),
],

Steps to Reproduce

1. Install package: composer require nwidart/laravel-modules
2. Publish config: php artisan vendor:publish --provider="Nwidart\Modules\LaravelModulesServiceProvider"
3. Add "App\\Modules\\": "app/Modules" to root composer.json autoload section
4. Run composer dump-autoload
5. Create module: php artisan module:make Platform

Expected Behavior

Modules should be discovered and loaded without errors.

Actual Behavior

Getting "provider not found" error.

Additional Context

• All configuration appears correct
• composer dump-autoload has been run
• Module structure is generated correctly by the package

Question

What additional steps or configuration am I missing to resolve this "provider not found" error in Laravel 12?

hi,
delete this line,

{
    "autoload": {
        "psr-4": {
            "App\\": "app/",
-            "App\\Modules\\": "app/Modules",
            "Database\\Factories\\": "database/factories/",
            "Database\\Seeders\\": "database/seeders/"
        }
    },
    "extra": {
        "laravel": {
            "dont-discover": []
        },
        "merge-plugin": {
            "include": [
                "app/Modules/*/composer.json"
            ]
        }
    }
}

Hi @alissn
I saw in the documentation that this line
"App\\Modules\\": "app/Modules", does not need to be in the root composer.json
but I keep getting the serviceprovider not found error but if I remove it from the module's module.json the error goes away

{
    "name": "Users",
    "alias": "users",
    "description": "",
    "keywords": [],
    "priority": 0,
-    "providers": ["Modules\\Users\\Providers\\UsersServiceProvider"],
    "files": []
}

Hi @owujib

Yes, that’s correct.

The service providers for the modules are loaded using the wikimedia/composer-merge-plugin, so there’s no need to remove the provider from module.json.
You only need to run the following command to allow Composer to detect the module providers:

composer dump-autoload

Also, make sure your main composer.json file includes the following configuration:

"extra": {
    "laravel": {
        "dont-discover": []
    },
    "merge-plugin": {
        "include": [
            "app/Modules/*/composer.json"
        ]
    }
}

[owujib]

Yes it has, this is the way it's referenced.

    "extra": {
        "laravel": {
            "dont-discover": []
        },
        "merge-plugin": {
            "include": [
                "Modules/*/composer.json"
            ]
        }
    },
