Larinfo Laravel Package

Getting Started

Release 4.3.0 is a compatibility release: the only stated change is Laravel 12 support. There are no announced API changes, deprecations, or breaking changes, so day-to-day usage is unchanged from 4.2.x — the work is in dependency verification, not in rewriting integration code.

Minimal steps to adopt it:

1. Check the constraint surface first. Confirm your app meets Laravel 12's baseline (PHP 8.2+) and that the package's composer.json now allows illuminate/* ^12. Run composer why-not <vendor>/<package> 4.3.0 before updating; this surfaces the transitive package still pinning you back.
2. Update with dependency resolution allowed: composer update <vendor>/<package> --with-all-dependencies. A plain composer update on a large app often resolves the package but leaves conflicting Illuminate versions in the lock file.
3. Re-run discovery and caches: php artisan package:discover (or composer dump-autoload), then php artisan config:clear && php artisan cache:clear. If the package ships publishable config or migrations, re-publish only when the changelog says to — never blindly re-publish over customized config.
4. Verify the primary entry point. Whatever the package's main surface is (facade, service, command, HTTP endpoint), exercise it once in a fresh Laravel 12 app before touching your production app. That isolates package/L12 incompatibilities from your own code.

Where to look first: the package's composer.json (version constraints), its test matrix in CI config (does it actually run against 12 or just declare support?), and the diff between 4.2 and 4.3 tags — a one-line release note often hides dependency and test-only changes worth confirming.

First use case: an existing Laravel 11 application upgrading to 12, where this package is one of several dependencies. Validate it in isolation first, then as part of the full upgrade.

Implementation Patterns

Constraint strategy during transition. If your app is still on Laravel 11, do not force 4.3.0 unless the package explicitly retains support for older Illuminate versions. Pin ^4.2 on L11 and ^4.3 on L12 until the upgrade is complete, otherwise you may pull a version whose constraints conflict with your framework.

CI matrix. Run the package version you ship against both Laravel 11 and 12 in CI for one release cycle. A green build on 12 alone does not prove you have not broken an app still on 11 that shares the same codebase.

Resolve through the container. Continue to inject the package's services or use its facade rather than instantiating classes directly. This matters more, not less, after a compatibility release — if the package internals shifted to accommodate L12 (container bindings, deferred providers), direct instantiation bypasses the resolution logic and fails in ways that are hard to trace.

Configuration over code. Any behaviour that differs between environments should live in the published config file, not in conditionals in your own code. After a major-version-adjacent update, this is what lets you verify behaviour by diffing config rather than re-reading the package source.

Test against the package's fakes/helpers. If it provides testing utilities, use them in feature tests so the upgrade shows up as failing assertions rather than runtime errors in staging. Add at least one integration test that touches the package end-to-end and runs on the L12 matrix leg — that is your regression net for future 4.x releases.

Queue and long-running work. If the package dispatches jobs or listeners, confirm after upgrading that serialization still works (payload class names, constructor signatures). Compatibility releases occasionally change internal class namespaces, which breaks jobs already sitting in the queue at deploy time. Drain or restart workers as part of the deploy.

Gotchas and Tips

• "Supports Laravel 12" is a claim, not a guarantee. Check whether the release actually runs against 12 in CI, and whether illuminate/* ^12 was added as an allow-list entry or whether older constraints were dropped. The latter is a silent breaking change for apps on 10/11.
• PHP 8.2+ is implied by Laravel 12. If your deploy images or CI runners are on 8.1, the failure will look like a package bug when it is an environment issue. Verify with php -v on every target.
• Lock file staleness. After composer update, commit composer.lock and confirm the resolved Illuminate versions in php artisan about match what you expect. A half-resolved lock is the most common cause of "it works locally."
• Config and route caching. php artisan config:cache bakes config at build time; if you publish config after caching, changes silently do nothing. Clear caches in the deploy script, after publish steps, not before.
• Facade and provider caching. New or renamed providers are not picked up until package:discover runs. On containerised deploys, ensure this runs during image build or as a release step.
• Queued payloads across the deploy boundary. Deploy the new version, then restart queue workers; do not let old workers process new payloads or vice versa.
• Debugging dependency conflicts. composer why-not vendor/package 4.3.0, composer prohibits, and composer show --tree are faster than reading error output. For runtime issues, php artisan about gives a one-screen environment summary worth pasting into bug reports.
• Extension points to prefer. Published config, container bindings for interfaces the package exposes, and its event/listener hooks. Avoid subclassing package internals — those are the classes most likely to shift in a compatibility release, and subclassing turns a patch upgrade into a merge conflict.
• Read the diff, not the note. For a release whose notes are one line, the tag diff is short. Five minutes there tells you whether anything in your integration surface moved, which the release note will not.
