Melodiia Laravel Package

Getting Started

Melodiia is a PHP/Symfony library, not a Laravel package — there is no service provider, facade, or config/melodiia.php publish step. Treat the first hour as a source-reading exercise, not an install-and-go.

1. Read in this order: README.md → docs/ (if present) → src/ (start at the controller/CRUD base classes and the kernel/event wiring) → tests/. With 17 stars and zero dependents, the test suite is the specification; there is no StackOverflow corpus to fall back on.
2. Install and pin: composer require swag-industries/melodiia — but commit an exact version ("swag-industries/melodiia": "x.y.z"), not a caret range. The advertised last release date (2026-10-10) is worth verifying against the actual tag list before you trust it.
3. Confirm the framework contract. Melodiia leans on Symfony HttpFoundation/Routing/Validator (and Doctrine ORM for its CRUD layer). Check which of those it requires vs. suggests before you plan anything, because Laravel already ships overlapping pieces.
4. First use case — one read-only endpoint. Build a single GET /api/things that returns a paginated JSON list. Define a model + repository, extend the library's CRUD controller, register one route, and assert the JSON envelope in a test. Do not attempt the full CRUD surface until that one endpoint is green.

If you are Laravel-only and cannot introduce Symfony components, stop here: the honest outcome is to borrow its conventions (resource controller shape, error envelope, pagination query params) rather than install it.

Implementation Patterns

Resource-per-controller. The package's centre of gravity is an abstract CRUD controller: you subclass it, supply a model/repository, and override only the verbs you need (list, get, create, update, delete). Keep business logic in the repository/domain layer and let the controller stay declarative — that is the pattern the library is optimised for.

Query-param contract. Listing endpoints typically come with filtering, sorting, and pagination driven straight off the request query string. Decide early whether you accept that default or map it onto your own convention; consistency across resources matters more than which one you pick.

Uniform error envelope. Errors are converted into a structured JSON payload by the library's exception handling rather than leaking stack traces. Adopt that shape at your API boundary from day one and make your domain exceptions render into it, so clients only ever parse one error format.

Serialization boundary. Implement the library's serializer/normalizer contract rather than returning Eloquent/Doctrine entities directly. This is where you control field exposure, dates, and relations — and where Laravel's JsonResource habit should be replaced with whatever interface Melodiia expects.

Bridging into Laravel (the realistic path). You have two options, and the second is usually better:

• Kernel bridge — boot a minimal Symfony HttpKernel inside a catch-all Laravel route and dispatch to it. Works, but you now own two containers, two routings, and two exception handlers.
• Component reuse — pull in only the pieces you want (pagination object, responder, exception-to-JSON mapping) and wire them into Laravel controllers yourself. You keep Laravel's container, middleware, and auth, and get Melodiia's API ergonomics.

Testing. Functional tests hitting routes and asserting the JSON envelope catch more regressions here than unit tests, because most of the value is in the request/response plumbing. Test pagination bounds and error payloads explicitly — those are the two things that silently drift.

Gotchas and Tips

• No Laravel integration exists. Any service provider, config publishing, or facade binding is code you write. Budget for it explicitly instead of discovering it mid-sprint.
• Two config surfaces. Configuration typically splits "API prefix" from "documentation/web prefix," plus pagination defaults and documentation toggles. Prefix mismatches are the most common cause of a 404 that looks like a routing bug.
• Documentation route toggles. Auto-generated/described endpoints should be disabled outside local and staging; verify the toggle actually closes the route rather than just hiding links.
• Exception swallowing. Because errors are normalised into JSON, an exception can vanish from your logs while still returning a 500-shaped body. Add logging at the handler boundary before you start debugging anything.
• Release-date anomaly. A future-dated release plus a low star count means you are an early adopter. Pin exact versions, read the diff between tags before upgrading, and be prepared to vendor a fork for a one-line fix.
• Zero dependents. There is no community troubleshooting. If something is undocumented, the answer is in tests/ — grep for the behaviour, not the class name.
• Extension points worth knowing: the responder/serializer (override to match Laravel's JsonResponse conventions), the paginator (swap in a cursor-based one for large tables), and the exception listener (route your domain exceptions through it). Prefer these three over patching vendor code.
• PHP/Symfony version floor. Check composer.json before scoping — a Symfony major that conflicts with your Laravel version is a hard stop, not a resolvable annoyance.
