LaravelCodeCommons

Shared Laravel/Livewire conventions, packaged once instead of hand-copied per project. These pieces used to live as near-identical copies across consuming apps and drifted; this package is the single canonical home.

Requires PHP 8.3+ and illuminate/support ^13.8 (Laravel 13). MIT-licensed.

Install

composer require mwebbers/laravel-code-commons

Until it is on Packagist, add the repository to the consuming app's composer.json:

"repositories": [
    { "type": "vcs", "url": "https://github.com/mwebbers/LaravelCodeCommons" }
]

What's in it

Support\Json — typed mixed narrowing

The single sanctioned place a JSON/config() mixed becomes a real type, which is what lets a consuming app keep PHPStan at level 10 without scattered casts. Every accessor degrades to a default instead of crashing on a wrong-typed or missing value.

use Mwebbers\LaravelCodeCommons\Support\Json;

Json::str($node['title'] ?? null, '(untitled)');   // string, scalars stringified
Json::int($config['limit'] ?? null, 50);           // int, numeric strings coerced
Json::rows($response->json());                      // list<array> — non-array rows dropped

Livewire\Concerns\WithCollectionSorting — a stable sortable-table concern

Click-to-sort for a Livewire table over an in-memory collection. Owns only the sort state and the toggle; the host supplies a column => extractor map. The sort is stable in both directions — equal-key rows keep their natural order whether ascending or descending (it uses sortByDesc, never a reverse() of the ascending sort, which would flip ties). Uses only Illuminate collections, so the logic is testable without a Livewire runtime.

use Mwebbers\LaravelCodeCommons\Livewire\Concerns\WithCollectionSorting;

class Tickets extends Component
{
    use WithCollectionSorting;

    public function render()
    {
        $rows = $this->sortedBy($this->tickets(), [
            'title'    => fn ($t) => $t->title,
            'deadline' => fn ($t) => $t->deadline?->getTimestamp() ?? PHP_INT_MAX,
        ]);
        // ...
    }
}

Livewire\TableRow is a tiny typed row DTO shipped as the reference shape to sort over (a generic callable(TValue) does not narrow an array-shape closure param under level 10, so a typed object keeps the example clean).

Livewire\Concerns\WithCollectionPagination — paginate an in-memory collection

Composes the sort concern with Livewire's pagination: it paginates an already-derived collection at perPage() rows, renders one page at a time, and resets to page 1 when the sort changes. An out-of-range ?page= clamps to the last real page — the URL is user-controlled input, and the data exists (just not 99 pages of it), so an empty table would be misleading. For a query builder use Livewire's native ->paginate(); this is for a set you already hold in memory.

Livewire\Concerns\LazyTableSkeleton — a #[Lazy] table's placeholder

Pairs with #[Lazy] to render a skeleton while the table body hydrates in a second request. It uses the page's real column headers so the skeleton auto-sizes like the live table (no layout shift). The placeholder view is app-provided — ship a livewire.placeholders.table Blade view (it carries your design system, e.g. Flux), or override skeletonView() to point at your own; a host overrides skeletonColumns() / skeletonRows() to match its table. A skeletonColumns() entry is either a bare label or a 'label' => alignment pair (start/center/end), so a column the live table end-aligns starts where it will end up — the view normalizes both forms. One caveat: a purely numeric label ('2024') cannot carry an alignment pair, because PHP coerces such array keys to int.

Testing\ScopeCoverage — the SCOPE↔test traceability checker

A coverage gate, extracted so every consuming app runs the same checker instead of a hand-copied ScopeCoverageTest. It reads the feature IDs from a SCOPE.md ## Features section and the #[Group('F-00X')] references across a tests directory, and reports either side's gaps.

An app's ScopeCoverageTest becomes a thin wrapper:

use Mwebbers\LaravelCodeCommons\Testing\ScopeCoverage;
use PHPUnit\Framework\TestCase;

final class ScopeCoverageTest extends TestCase
{
    public function test_scope_and_tests_stay_in_sync(): void
    {
        $coverage = new ScopeCoverage(dirname(__DIR__, 2).'/SCOPE.md', dirname(__DIR__, 2).'/tests');
        $result = $coverage->mismatch(__FILE__);

        $this->assertSame([], $result['missing'], 'SCOPE features with no test: '.implode(', ', $result['missing']));
        $this->assertSame([], $result['stale'], 'Test groups for unknown features: '.implode(', ', $result['stale']));
    }
}

Roadmap

Planned for later minors: a DuskTestCase base for browser smoke tests, and publishing to Packagist (so consumers can drop the VCS repositories entry). See CHANGELOG.md.
