Json Exception Response Bundle Laravel Package

Getting Started

1. Install via Composer and confirm the resolved Symfony component versions are ^5.0 — this release is primarily a compatibility bump, so the first check is that your app’s Laravel version ships Symfony 5 components (Laravel 7+).
2. Run composer require <vendor>/<package> and watch the solver output. If you are on an older Laravel version pinned to Symfony 4, Composer will either fail or silently keep an older package release; verify with composer show <vendor>/<package>.
3. Look first at the package’s service provider and config/ file. Publish config if available (php artisan vendor:publish --provider=...) and inspect the default bindings before writing any integration code.
4. First use case: resolve the package’s primary service from the container inside a controller or queued job, exercise it against a non-production endpoint, and confirm the Symfony 5 HTTP/event contracts behave as expected (especially if the package wraps HTTP client, routing, or event dispatcher behavior).

Implementation Patterns

• Container-first usage. Prefer constructor injection or app(Contract::class) over facades so you can swap implementations in tests and respect any bindings registered by the provider.
• Config-driven setup. Keep environment-specific values in config/<package>.php and reference them via config(), not hardcoded values. Cache-clearing (php artisan config:clear) should be part of your deploy checklist.
• Queued integration. If the package performs I/O, wrap calls in jobs with retries and backoff. Symfony 5 compatibility may change exception types thrown by underlying components; catch broadly at the job boundary and let failures surface in failed_jobs.
• Testing seam. Use the package’s provided fake/mock if one exists; otherwise bind a test double in the container within setUp(). Assert on observable side effects rather than internal Symfony 5 classes.
• Version pinning in CI. Add a CI matrix step that runs composer why symfony/http-foundation (or equivalent) so an unrelated dependency bump cannot silently downgrade you to Symfony 4 and break the package.
• Upgrade sequencing. When moving a Laravel app forward, update Laravel and this package together. Do not upgrade the package in isolation on a framework still on Symfony 4.

Gotchas and Tips

• This release is a compatibility change, not a feature release. The only stated change is Symfony 5 support. Treat the upgrade as low-risk functionally but verify transitive dependency constraints — a package that now requires Symfony 5 will conflict with any dependency still capped at ^4.4.
• Check composer.lock diffs carefully. A "support" bump can widen or tighten constraints. Confirm whether the new constraint is ^5.0 only or ^4.4|^5.0; the latter preserves backward compatibility, the former is effectively a breaking change for older apps even without a major version bump.
• Watch for deprecation noise. Symfony 5 removed several deprecated APIs from 4.4. If the package previously relied on them, you may see E_USER_DEPRECATED notices or, worse, Error/TypeError at runtime. Enable deprecation logging in staging before production.
• Auto-discovery and config cache. After upgrading, run php artisan package:discover and php artisan config:cache in a clean environment. Stale cached providers are a common cause of "class not found" after a version change.
• Debugging approach. Reproduce with a minimal artisan tinker session resolving the service, then enable Symfony’s debug mode / Laravel’s query and event logging to isolate whether the failure is in the package or in the framework bridge.
• Extension points. If the package exposes events, contracts, or a manager class, prefer extending through those rather than subclassing internals — internal Symfony-facing code is exactly what changes between major compatibility releases.
• No migration guide was provided. Given the terse release note, pin the exact version in composer.json, read the package’s diff for the release if the repository is available, and add a smoke test covering your primary use case before rolling out.
