Laravel Jsend Laravel Package

Getting Started

Laravel 10 support is the headline of 2.4, so the first job is confirming your app actually falls inside the supported matrix before you adopt anything else.

1. Check the constraint, not the changelog. Open the package's composer.json and read require / require-dev. You want illuminate/support (and friends) at ^10.0, plus the PHP floor — Laravel 10 requires PHP 8.1, so any package that claims 10 support must have bumped its own PHP constraint. If it still says ^8.0, the support is nominal and you should not trust it in production.
2. Install on a throwaway branch. composer require vendor/package:^2.4 on a branch, then composer why-not vendor/package 2.4 if resolution stalls. On an existing Laravel 9 app this is usually the fastest way to see which sibling dependency is still pinned to ^9.0.
3. Read the service provider. vendor/vendor/package/src/*ServiceProvider.php tells you what is registered, whether config/migrations are publishable, and whether anything is deferred. This is the single most useful file for understanding day-to-day behaviour.
4. Publish and diff. php artisan vendor:publish --provider="Vendor\Package\PackageServiceProvider" and diff the published config against the package default — config keys occasionally get renamed across majors and 2.x is where that tends to land.
5. First use case. The quickest sanity check is a single feature test that exercises the package end-to-end (RefreshDatabase + one call through its public API), run under php artisan test. If it passes on Laravel 10 there, the rest is integration detail.

Where to look first, in order: composer.json, README install section, the service provider, config/, then src/ contracts.

Implementation Patterns

Treat the version bump as a compatibility gate, not a feature. 2.4 is a maintenance release; the practical pattern is to pin ^2.4 in apps already on Laravel 10 and leave Laravel 9 apps on ^2.3 until they upgrade. Avoid * or unbounded constraints — this package has now demonstrated it will move its framework constraint in a patch/minor.

Upgrade sequence for a Laravel 9 → 10 app. Bump the framework first (laravel/framework:^10.0, nunomaduro/collision, phpunit/phpunit:^10), get the app's own tests green, then pull this package to ^2.4. Doing both at once makes failures ambiguous.

Resolve through the container, not new. Register and resolve the package's classes via the container so any Laravel 10 changes to binding resolution or constructor injection are exercised. Facades should be accessed through their documented alias; check extra.laravel.aliases in composer.json for what the package registers.

Isolate the package behind a thin adapter. If the package exposes anything you call in more than three places, wrap it in your own class or interface. This is the cheapest insurance against a future major, and it means a 2.4 → 3.0 bump touches one file.

Exercise it through queued work. Packages that touch Eloquent, notifications, or HTTP clients behave differently inside a queued job (SerializesModels, container rebuilds). If your code path is async, test it with Queue::fake() and with a real sync connection — a sync-only test suite hides serialization regressions.

Testbench alignment for package consumers writing tests. If you maintain your own package that depends on this one, align orchestra/testbench to the Laravel 10 line (^8.0) or you will get duplicate service providers and confusing container state.

Use Illuminate\Support\Facades\Date and Carbon 2. Laravel 10 ships Carbon 2; if this package parses or returns dates, freeze time with $this->travelTo() in tests rather than asserting on now().

Gotchas and Tips

• "Laravel 10 support" often means "we widened a constraint and ran CI." It does not guarantee the package has adopted Laravel 10 idioms — dispatchNow(), Bus::dispatchNow, and the old Model::preventLazyLoading signatures can linger. Grep vendor/vendor/package for dispatchNow, $dates, and getKeyName usage if you hit deprecation noise.
• PHP 8.1 is now your floor. If your app still runs 8.0, composer update will fail with a confusing platform error. Check platform.php in your root composer.json — a hardcoded platform config there silently overrides your actual interpreter and blocks the upgrade.
• Silent version downgrade. composer update on a stale lockfile can quietly leave you on 2.3 if another dependency conflicts. Confirm with composer show vendor/package after updating; don't trust that the update succeeded because there was no error.
• Config caching. php artisan config:cache after publishing config — if the package reads config at service-provider boot rather than at resolution, values cached during a deploy can differ from values in tests. If behaviour diverges between php artisan serve and a cached deploy, this is nearly always why.
• Migrations are usually the upgrade risk, not the code. Laravel 10 changed default column modification behaviour around doctrine/dbal. If the package publishes migrations, run them against a copy of production data before deploying, and check whether any existing column-modification paths were quietly relying on the dropped DBAL behaviour.
• Extension points to prefer. Published config, container bindings against the package's interfaces, and event/listener hooks are stable surfaces. Subclassing a concrete package class is not — it is the first thing to break on a major.
• Debugging tip. Wrap a failing call in app()->make() and inspect the resolved class via get_class(); facades in older packages sometimes resolve to a different concrete implementation than the README implies, and Laravel 10's container error messages are more explicit about unresolvable constructor dependencies than earlier versions.
• Pin and record. Since this release is a constraint widening rather than a behaviour change, add the exact version to your upgrade notes and set "vendor/package": "^2.4" explicitly, so the next Laravel framework bump doesn't drag an untested package version along with it.
