Product Ranking Bundle Laravel Package

Getting Started

Reality check on 0.0.1: the only artifact published with this release is a changelog link. There is no README excerpt, no documented API surface, and no migration or config reference in the release notes. Treat 0.0.1 as a source-reading exercise, not a documented integration.

1. Install and pin exactly. Because this is a 0.0.x release, Composer will treat it as unstable-ish semver (0.0.1 has no backward-compatibility promise). Require "tourze/product-ranking-bundle": "0.0.1" with an exact constraint, and commit the lock file.
2. Look at composer.json first. Confirm three things before writing any code:
   • the type field — symfony-bundle versus library tells you whether Laravel's package auto-discovery will do anything for you;
   • the require block — whether it pulls in symfony/* components, Doctrine, or nothing framework-specific;
   • the PSR-4 autoload prefix, which tells you the real root namespace to use (the package name suggests Tourze\ProductRankingBundle, but verify rather than assume).
3. Read .github/workflows/, composer.json require-dev, and any tests/ directory. With no docs, the test suite is the specification. Tests tell you the intended data shape, the ranking algorithm's tie-breaking behaviour, and whether persistence is expected to be supplied by you or by the bundle.
4. Then read src/. Scan for a service provider or Symfony *Extension class (the config entry point), any Repository/Ranker/Calculator/Sorter classes (the actual API), and any Resources/config/ or config/ directory (default options and their keys).

First use case to attempt: a read-only ranking query — take a collection of products with a numeric score, feed it to whatever ranking/sorting service the package exposes, and render the top N. Do this before you touch persistence or write paths, because a 0.0.1 ranking package is most likely to be a pure scoring/sorting library with the storage layer left to you. If that read-only path works, you have learned the core contract; if it requires database tables that don't ship, you have learned that immediately and cheaply.

Implementation Patterns

Wrap it, don't sprinkle it. Put a single ProductRanking adapter class in app/Services/ that owns every call into the package. On a 0.0.x dependency this is not ceremony — it is your upgrade insurance. If 0.0.2 renames a method, you edit one file.

Bind the contract in a service provider. If the package ships interfaces, register concrete bindings in AppServiceProvider::register() rather than resolving classes from the container inline. This is also where you inject your ranking configuration (weights, score sources, limits) so the package stays framework-agnostic and your app owns the policy.

Compute on write, read from a materialised table. Ranking at request time is the pattern that ages badly. Store a rank or score column (or a dedicated product_rankings table) and recompute on a schedule or on relevant model events. The package almost certainly gives you the ordering logic but not the storage — so you own the table, the index, and the recompute trigger.

Use a queued job for bulk recomputation. If ranking is O(n log n) over a full catalogue, a queued RecalculateProductRankings job with WithoutOverlapping middleware prevents a redeploy or a double-click from stacking concurrent recomputes over the same rows.

Scope by tenant/store explicitly. Multi-tenant catalogues break naive ranking because a global top-10 leaks cross-tenant data. If the package's API takes no scope parameter, apply scope in your adapter — filter the candidate set before ranking, never after.

Keep a deterministic tie-breaker. Ties in score are where ranking bugs hide. Always append a stable secondary sort (e.g. product_id ASC) after the package's ordering so paginated results don't reshuffle between page 1 and page 2.

Feature-flag the rollout. Given undocumented behaviour, ship behind a config flag or Laravel Pennant feature so you can compare package output against your existing ordering in production before flipping over.

Gotchas and Tips

• "Bundle" is a Symfony word. The package name strongly suggests a Symfony bundle rather than a Laravel package. Laravel's extra.laravel.providers auto-discovery will silently do nothing if that key is absent. Check composer.json; if there is no Laravel provider, you may need to register services manually or write a thin bridge. Budget for this — it is the single most likely source of a "nothing happens" first hour.
• No documented config means no known defaults. Look for a publishable config (php artisan vendor:publish) or a Symfony Configuration class. If neither exists, configuration is either constructor arguments or absent, and hard-coded defaults are baked into the code — grep for magic numbers.
• Migrations may not ship. If the package expects an entities/tables that it does not create, you will get "table not found" on first query. Check for a Migrations/ or migrations/ directory; if empty, you are writing the schema.
• Pinning is not optional. A 0.0.1 → 0.0.2 bump can legitimately rename classes, change return types, or invert sort direction — under semver that is allowed in the 0.0.x range. Use an exact constraint and read the diff before bumping. Treat every upgrade as a minor review task.
• Sort direction is the classic silent failure. Descending-by-default versus ascending-by-default produces plausible-looking but wrong output that no exception will catch. Assert the first result is the highest scorer in a test before trusting anything downstream.
• Cache invalidation is on you. If you cache ranked lists, key the cache on both the scope (tenant/store) and a catalogue version counter that you bump on any score-affecting write. Keying only on tenant gives you stale rankings that look fresh.
• Add a database index before you need it. If you persist a rank/score column, index it together with your scope column (store_id, rank) — the read path is almost always "top N within scope", and without the composite index you will table-scan once the catalogue grows.
• Log the package's input and output on first integration. A temporary debug log of the candidate set size and the returned ordering, run against a known fixture, is the fastest way to confirm the package is doing what you think before you wire it into a request path.
• Extension points to look for: interfaces you can implement (custom scorers/comparators), events dispatched around recompute, and any strategy/policy class that can be swapped via container binding. On 0.0.1 these may not exist yet — if they don't, keep your adapter thin so that adding them later is cheap rather than a rewrite.
