- What is chilldev/dependency-injection-extra used for?
- It provides commonly used patterns and helpers for Symfony2's dependency injection component, extending compiler passes and service definitions. It targets Symfony2 bundle-era applications, not Laravel. Its patterns include service wiring conveniences such as factories, decorators, lazy services, and tagged collections, which Laravel already handles natively.
- Does chilldev/dependency-injection-extra work with Laravel?
- No. Laravel uses Illuminate\Container, not symfony/dependency-injection, so there is no integration seam for Symfony compiler passes. Installing it would mean running a second container alongside Laravel's, which is an anti-pattern. Treat it as a read-only reference if you want pattern ideas.
- Can I install chilldev/dependency-injection-extra in Laravel 10, 11, or 12?
- Composer will likely refuse because constraints target PHP 5.x and symfony/dependency-injection ~2.x, while modern Laravel requires PHP 8.1+ and Symfony 6/7 components. Even a vendored fork would need rewritten constraints and an adapter layer. At that point you have written a new library rather than integrated this one.
- What PHP and Symfony versions does this package require?
- It is a Symfony2-era library, so expect PHP 5.x and symfony/dependency-injection 2.x constraints. Symfony 2.8 reached end of life in November 2018. Those requirements conflict with current Laravel and PHP versions.
- How does it compare to Laravel's bind, singleton, extend, and tag features?
- The package's value proposition overlaps heavily with native Laravel container features. Laravel bind and closures cover factory-style wiring, extend covers decorators, tag and tagged cover tagged-collection patterns, and deferred providers cover lazy service registration. Adopting the package would duplicate capabilities you already have.
- How do I configure chilldev/dependency-injection-extra?
- Configuration is handled through Symfony2 bundle and service-definition conventions, including compiler passes. There is no Laravel service provider or config file for it. In a Laravel app you would have to build a custom bridge, which is not recommended.
- Is chilldev/dependency-injection-extra maintained or safe for production?
- It has no meaningful maintenance signal: zero stars, zero dependents, and a Symfony2 EOL baseline. No active maintainer means no coordinated disclosure path for security issues. Even if container wiring has low CVE surface, an unpatched dependency graph is a production risk. Decline it as a runtime dependency.
- How would I test this package in a Laravel project?
- You cannot meaningfully test it against Laravel's container without a fork and adapter, because the compiler-pass extension model does not plug into Laravel's boot cycle. A spike would only prove that two containers can coexist, not that the package adds value. If you need the patterns, test native Laravel implementations instead.
- What are the alternatives for complex service wiring in Laravel?
- Use Illuminate\Container directly: bind and singleton for factories, extend for decorators, tag and tagged for plugin registries, contextual binding for interface selection, and deferred providers for boot-time cost. If you need reusable helpers, write a small internal package on top of the native container with tests and a supported PHP/Laravel matrix.
- Is there a migration path from Symfony2 DI patterns to Laravel's container?
- There is no incremental migration path because the package has no Laravel starting point. The practical route is pattern extraction: inventory the patterns you actually need, confirm which Laravel already covers, and build only the genuine gaps internally. Budget that as greenfield work, roughly one to two engineer-weeks for a small helper set plus tests.
