README

Optional / experimental — not the primary workspace UI. Per charter directive DIR-007 (docs/governance/charter.md), the committed workspace UI is the Nuxt SPA in packages/admin/. This L6 adapter is supported for distributions that prefer server-driven UI, but is not bundled by waaseyaa/full.

Layer 6 — Interfaces

Server-side Inertia.js v3 protocol adapter. A controller returns Inertia::render($component, $props), producing an InertiaResponse that carries the Inertia page object. InertiaMiddleware reads the X-Inertia-* headers to tell an initial full-page load (HTML via RootTemplateRenderer) from an XHR navigation (JSON page object), and returns 409 + X-Inertia-Location on an asset-version mismatch. Implements the foundation contracts InertiaPageResultInterface and InertiaFullPageRendererInterface.

Partial reloads are not yet wired (experimental). OptionalProp and PropResolver are provided as standalone building blocks for deferring expensive props (PropResolver::resolve($props, $only, $except)), but nothing in this package invokes them: InertiaMiddleware reads only X-Inertia / X-Inertia-Version (not the X-Inertia-Partial-Data partial-reload header), and InertiaResponse carries the full prop set unchanged. So a partial reload currently returns all props, not just the requested keys. Honoring only / except automatically is unbuilt — call PropResolver directly in a controller if you need it today.

Install

Ships in the waaseyaa/framework metapackage but is not pulled in by waaseyaa/full; add it explicitly: composer require waaseyaa/inertia. Register Waaseyaa\Inertia\InertiaServiceProvider (auto-discovered via extra.waaseyaa.providers) to wire the renderer and HTTP middleware.

Key API

// Inertia — static response factory + shared-prop / version state.
Inertia::setVersion(string $version): void
Inertia::getVersion(): string
Inertia::setRenderer(RootTemplateRenderer $renderer): void
Inertia::getRenderer(): RootTemplateRenderer
Inertia::share(string $key, mixed $value): void
Inertia::render(string $component, array $props, bool $encryptHistory = false, bool $clearHistory = false): InertiaResponse
Inertia::reset(): void

// InertiaResponse implements InertiaPageResultInterface — readonly: component, props,
//   url, version, encryptHistory, clearHistory, preserveFragment, and the
//   deferred/merge/prepend/deepMerge/once prop sets.
public function toPageObject(): array

// InertiaMiddleware — #[AsMiddleware(pipeline: 'http', priority: 20)]
public function __construct(string $version)
public function process(Request $request, HttpHandlerInterface $next): Response

// PropResolver
public static function optional(\Closure $callback): OptionalProp
public function resolve(array $props, array $only = [], array $except = []): array

// RootTemplateRenderer implements InertiaFullPageRendererInterface
public function __construct(?\Closure $template = null, ?ViteAssetManager $assetManager = null)

Usage

Inertia::setVersion('abc123');
Inertia::share('auth', fn() => ['user' => currentUser()]);
$response = Inertia::render('Users/Index', ['users' => [1, 2, 3]]);
$page = $response->toPageObject();

Page props override shared props of the same key; shared closures resolve fresh per render(); toPageObject() always injects props.errors.
