Getting Started

Install and verify before you build on it.

composer require threeleaf/biblioteca

Laravel's package discovery should register the service provider automatically. If not, add ThreeLeaf\Biblioteca\BibliotecaServiceProvider::class to config/app.php.

Publish whatever the package ships:

php artisan vendor:publish --provider="ThreeLeaf\Biblioteca\BibliotecaServiceProvider"
php artisan migrate

Inspect the publish tags first (--tag=config, --tag=migrations) so you don't dump unrelated assets into your app. Then read the source before trusting the README — with 0 stars and 0 dependents, the code is the documentation:

src/Models/ — the actual Eloquent model set (expect Book, and likely Author, Publisher, Genre/Subject, possibly Series).
database/migrations/ — table names, column types, nullability, indexes, and any pivot tables. This is where the real API lives.
src/Providers/ or the service provider — config keys, model bindings, and any mergeable config.
composer.json — supported Laravel/PHP versions and whether it declares a laravel illuminate constraint broadly or narrowly.

First use case: a read-only bibliographic catalog. Seed a few hundred books with authors and publishers, then attach your own domain records (reviews, loans, reading lists, inventory) to Book by foreign key. Treat Biblioteca as the reference-data layer and keep your business logic in your own models.

$book = \ThreeLeaf\Biblioteca\Models\Book::create([
    'title'  => 'The Left Hand of Darkness',
    'isbn'   => '9780441478125',
]);

$book->authors()->attach($author->id); // verify relationship name/shape in source

If the model names or relations differ from the above, trust the migration files over any assumption — the schema is authoritative.

Implementation Patterns

Wrap the package, don't scatter it. Create thin app-level models that extend the package models, so you can add scopes, casts, and accessors without forking:

namespace App\Models;

class Book extends \ThreeLeaf\Biblioteca\Models\Book
{
    protected $with = ['authors']; // or leave empty and eager-load per query

    public function reviews() { return $this->hasMany(Review::class); }
}

Then map the package model to yours once, in a service provider:

// AppServiceProvider::boot()
$this->app->bind(\ThreeLeaf\Biblioteca\Models\Book::class, \App\Models\Book::class);

Whether this actually rewires internal relations depends on how the package resolves models — check for a config-driven models array or hardcoded belongsTo(Author::class) calls. Hardcoded references won't follow your binding; subclassing the related models too is the fallback.

Keep your data in your tables. Add your own migrations for reviews, loans, reading_list_items, etc., with foreignId('book_id')->constrained('books') (verify the actual table name — packages often prefix, e.g. biblioteca_books). Never edit published package migrations; add new ones.

Repository or query-object layer for catalog search. Bibliographic search gets messy (title vs. subtitle, author sort names, ISBN-10 vs. ISBN-13, transliteration). Encapsulate it:

final class BookSearch
{
    public function __invoke(array $filters): Builder
    {
        return Book::query()
            ->when($filters['q'] ?? null, fn ($q, $term) =>
                $q->where(fn ($q) => $q
                    ->where('title', 'like', "%{$term}%")
                    ->orWhereHas('authors', fn ($q) =>
                        $q->where('name', 'like', "%{$term}%"))))
            ->when($filters['author_id'] ?? null,
                fn ($q, $id) => $q->whereHas('authors', fn ($q) => $q->whereKey($id)));
    }
}

Seeding. Build factories against your subclassed models (Book::factory() won't exist unless the package ships one). Seed authors/publishers first, then books, then attach pivots — and use Author::factory()->count(3)->create() style helpers rather than raw insert loops so pivot IDs are real.

API surface. Use JsonResource classes with explicit field selection:

return [
    'id'    => $this->id,
    'title' => $this->title,
    'isbn'  => $this->isbn,
    'authors' => AuthorResource::collection($this->whenLoaded('authors')),
];

Never return $book; directly — package models may expose timestamps, pivot data, or columns you didn't intend to publish.

Import pipelines. If you're ingesting from Open Library / Google Books, write an idempotent importer keyed on ISBN with updateOrCreate, and normalize ISBNs to 13 digits before insert. Bibliographic data is dirty; expect duplicate authors under spelling variants.

Caching. Catalog reads are near-static. Cache rendered book pages and search facets with Cache::remember, keyed on the query hash, and bust on model events via an observer.

Gotchas and Tips

License is the headline risk. GPL-3.0 is a strong copyleft license. If you distribute a Laravel app that includes this package, the GPL's derivative-work argument is contested for PHP libraries but not something to decide casually. Running it on a private SaaS backend is generally lower risk (no distribution); shipping a downloadable/self-hosted product is not. Get a legal read before adopting, or plan to vendor-and-replace the models if the schema is all you actually want. This alone should decide adoption for most commercial teams.

Zero stars, zero dependents, single maintainer. There is no community safety net. Practical mitigations:

Pin an exact version in composer.json ("threeleaf/biblioteca": "1.2.3"), not ^.
Commit composer.lock.
Fork to a private VCS repo and point repositories at your fork so an upstream deletion or force-push can't break your build.
Read every release diff before upgrading.

The release date looks wrong. 2026-09-05 is in the future relative to normal package metadata. Could be a typo, a timezone/epoch artifact, or a republished tag. Verify with composer show threeleaf/biblioteca and check the git tags directly — don't assume composer require gives you something stable.

Migration and table-name collisions. Packages that ship migrations sometimes use generic names (books, authors) that clash with existing tables or with other packages. Read the migration filenames and Schema::create calls before running migrate. If a collision is likely, publish only the config and hand-write your equivalent schema.

Publishing migrations means frozen schema. Once you've published and migrated, upstream schema changes arrive as new migration files, not edits — you must re-publish and apply incrementally. Keep the published set under version control and diff it on upgrade.

Relationship assumptions break. Expect belongsToMany vs. hasMany mismatches for authors (single author column vs. pivot table), and Genre/Subject/Category naming inconsistency. Confirm with php artisan tinker:

>>> $b = \ThreeLeaf\Biblioteca\Models\Book::first();
>>> $b->authors()->toSql();
>>> \Illuminate\Support\Facades\DB::getQueryLog();

N+1 is inevitable on catalog listings. Always ->with(['authors', 'publisher']). Consider Model::preventLazyLoading(! app()->isProduction()) in AppServiceProvider so missing eager loads fail loudly in dev.

Nullable bibliographic fields. ISBNs, publication dates, page counts, and subtitles are all frequently absent in real data. Do not add NOT NULL constraints in your own migrations that depend on package columns; validate at the form-request layer instead, and store publication dates as strings or partial dates if the package does (a date cast on "1974" will throw).

Extension points to use instead of forking: model subclassing + container binding, Eloquent observers/events (Book::observe(...)), custom casts for ISBN/date normalization, config overrides for table names if supported, and a repository layer around reads. Fork only if you need to change schema or relationship definitions.

No tests upstream means you write the integration tests. Cover: model creation, each relationship's cardinality, cascade behavior on delete, and your own migrations. Use RefreshDatabase and assert table existence explicitly so an upgrade that renames a table fails fast:

$this->assertTrue(Schema::hasTable('books'));

Debugging checklist when something's silently wrong: php artisan model:show Book (Laravel 9+) to see actual columns and relations; php artisan migrate:status to confirm package migrations ran; composer show for the resolved version; and grep the package source for config( and env( to find undocumented configuration knobs.

Honest verdict: the schema is the valuable part; the code is small and readable enough to reimplement in a day. Given the GPL license plus zero adoption, the strongest play for a real product is to study the migrations, write your own models, and skip the dependency — or fork it under a license you're comfortable with.
