A PHPStan extension that validates Inertia.js page existence on disk when used in Laravel controllers.

Features

• Validates Inertia::render() static calls
• Validates inertia() helper function calls
• Validates $this->inertia() method calls in controllers
• Supports multiple page directory configurations
• Supports various file extensions (.vue, .jsx, .tsx, .js, .ts)
• Handles both dot notation (Auth.Login) and slash notation (Auth/Login) for page names

Installation

Configuration

Add the extension to your phpstan.neon:

includes:
    - vendor/adrum/inertia-phpstan/extension.neon

Usage

The extension will automatically validate that Inertia pages exist on disk when analyzing your controllers:

class UserController extends Controller
{
    public function dashboard()
    {
        // ✓ Will pass if resources/js/Pages/Dashboard.vue exists
        return Inertia::render('Dashboard');
    }

    public function profile()
    {
        // ✗ Will fail if resources/js/Pages/Profile/Edit.vue doesn't exist
        return Inertia::render('Profile/Edit');
    }
}
