Inertia Development Skill

Inertia Development

When to use this skill

Use when implementing or reviewing Inertia.js pages, components, forms, or navigation in a Laravel app (React or Vue).

Directory structure

resources/js/
  common/    # shared UI primitives
  modules/   # feature/domain code
  pages/     # Inertia-rendered pages (mirrors URL structure)
  shadcn/    # generated shadcn-ui (React) — do not edit directly
  lib/       # third-party UI library components (Vue)
  app.tsx / app.ts

React conventions

Page components — suffix Page, default export, typed props:

interface PostsIndexPageProps { posts: Post[] }
export default function PostsIndexPage({ posts }: PostsIndexPageProps) { ... }

Components — one per .tsx file, function declaration, PascalCase filename:

export function Button({ children }: ButtonProps) { ... }  // Button.tsx

Forms — use useForm, never raw axios/fetch:

const { data, setData, post, processing, errors } = useForm({ title: '' });

Shared data — use usePage<SharedProps>().props, not prop drilling:

const { auth } = usePage<SharedProps>().props;

Navigation — use <Link>, not <a>:

<Link href="/posts">View Posts</Link>

Vue conventions

Page components — suffix Page, default export via <script setup>:

<!-- PostsIndexPage.vue -->
<script setup lang="ts">
defineProps<{ posts: Post[] }>();
</script>

Components — one per .vue file, PascalCase filename, prefer <script setup> + Composition API.

Third-party UI — keep under lib/, wrap in common/ with a project-friendly API.

Shared conventions (React + Vue)

Directories: kebab-case. Component files: PascalCase. Helpers/hooks/composables: camelCase .ts.
Avoid barrel/index files — import directly: @/common/button/Button.
Wrap shadcn/third-party components; never import them directly across the app.
Partial reloads: router.reload({ only: ['propName'] }) instead of full visits to refresh one prop.
Deferred props: mark expensive data with Inertia::defer() on the server to load after first render.

Rules reference

See rulebook.json entries INRT-001–INRT-010 (React) and INRT-VUE-001–INRT-VUE-005 (Vue).
