tbtop/admin

Tabletop — Laravel + Inertia admin builder

An admin builder: pages are authored in a PHP DSL, serialized to a JSON structure in Inertia props, and rendered by a React interpreter. Filament's authoring model, without Livewire.

Run the demo

# the demo aliases @tbtop/inertia-admin to packages/client/src, whose Tailwind
# source pulls its own deps — install them first
(cd packages/client && bun install)

cd apps/demo
composer install && npm install
cp .env.example .env && php artisan key:generate
touch database/database.sqlite
php artisan migrate --seed && php artisan storage:link
npm run dev                     # keep running: without a Vite dev server or a
                                # prior `npm run build`, admin pages 500 on the
                                # missing manifest
php artisan serve --port=8090   # in a second terminal
# http://127.0.0.1:8090/admin/posts — admin@admin.com / password

A page in 30 seconds

class PostsIndexPage extends Page
{
    public static function path(): string { return 'posts'; }

    public static function nav(): ?array
    {
        return ['group' => 'Content', 'label' => 'Posts', 'order' => 1];
    }

    public function view(S $s): Node
    {
        return $s->stack([
            $s->table('posts')
                ->columns(['title' => 'Title', 'views' => 'Views'])
                ->searchable(['title'])
                ->defaultSort('created_at', 'desc')
                ->query(fn () => Post::query())
                ->rowActions([
                    $s->action('edit')->label('Edit')
                        ->url('/admin/posts/{row.id}/edit'),   // row template
                    $s->action('delete')->label('Delete')->color('danger')
                        ->confirm('Delete this post?')
                        ->handle(function (ActionCtx $ctx): Effects {
                            Post::whereKey($ctx->row['id'])->delete();
                            return Effects::make()->notify('Deleted')->refreshTable();
                        }, needs: ['row']),
                ])
                ->toNode(),
        ]);
    }
}

Registration: nothing per page. A panel (listed once in config/tbtop-admin.php → 'panels') declares a discovery root in its configure() — ->discoverPages(in: app_path('Admin/Pages'), for: 'App\\Admin\\Pages') — and every page class under it is found and routed automatically. Adding a screen is php artisan make:tbtop-page Posts and nothing else. Pages outside that root (package-owned ones such as the media library) and any page that must come first are listed explicitly with ->pages([...]); discovery merges them and drops duplicates. Routes and the table/data/form/action endpoints are wired under the panel's prefix + middleware.

Discovery results are cached: run php artisan tbtop:cache-pages in deployment, and php artisan tbtop:clear-cached-pages after adding a page locally if the cache is warm.

Forms

$s->form('post', [
    $s->text('title')->label('Title')->required()->rules('max:200'),
    $s->text('intro')->label('Intro')->translatable(),   // per content locale
    $s->repeater('sections')->rules('array|max:10')->set('fields', [
        $s->text('heading')->required(),
    ]),
    $s->actionsRow([
        $s->action('save')->label('Save')->keybinding('mod+s')->submit(),
    ]),
])
->record($post->toArray())                       // initial data → props
->onSubmit(function (ActionCtx $ctx): Effects {  // $ctx->form = validated
    $post->update($ctx->form);
    return Effects::make()->notify('Saved');
});

• Laravel owns validation: rules are collected from the fields (repeater → parent.*.child), validate() → 422 → errors land on the fields. Regex rules must use the array form.
• The declarative subset of rules ships to the client as constraints for on-blur validation.
• Submit goes through Inertia router.post (errors bag, history); success effects arrive via flash.
• A field with no rules gets a baseline nullable (otherwise Laravel drops it from the validated payload).

Actions — five kinds

->confirm(title) wraps a server action in a confirm modal. Server closures resolve by name per-request — they never travel over the wire.

Effects (a closed set): notify | redirect | refreshTable | resetForm | closeModal | haltModal | copyToClipboard | setFormData. The set is closed: anything non-standard goes through custom or a server redirect. Adding an effect means changing the schema, the PHP builder and the client interpreter together, so it is a contract change, not an extension point.

Uploads

An upload field carries its own storage config — there is no global profile registry, and the client cannot override any of it:

$s->upload('doc')->label('Document')
    ->disk('public')->directory('docs')->visibility('public')
    ->accept('image/*')->maxSize(5 * 1024 * 1024)
    ->convertTo('webp')->quality(80),          // optional GD conversion
$s->upload('gallery')->multiple()->maxFiles(8)->reorderable(),

The endpoint is page-scoped — POST {page-path}/uploads/{field} — and inherits the page's gate. It answers {data: {path, url}}, and the form value is the path string (a list of them when multiple()), so $ctx->form['doc'] is what you persist. A private field's url comes back signed and short-lived, so the preview renders without exposing the file publicly. saveUsing() replaces the storage step when you need your own.

The media library is a separate feature with its own manager, tables and config ('media' in config/tbtop-admin.php) — use $s->media() for it.

The contract

packages/contracts/structure.schema.json is the wire grammar. Gates:

• PHP: the kitchen-sink page validates against the schema + a snapshot (UPDATE_FIXTURES=1 vendor/bin/pest to regenerate);
• client: the same fixture passes the zod mirror and a render smoke test.

A new block = update the schema + the zod mirror + the fixture in one PR.

Quality gates

cd packages/php && vendor/bin/pest && vendor/bin/phpstan analyse && vendor/bin/pint --test
cd packages/client && bun test && bunx tsc --noEmit
cd apps/demo && php artisan test

phpstan runs at level 5 (the skeleton default; raise it in phpstan.neon.dist).
