Cache Laravel Package

Product Decisions This Supports

• Build vs. buy for a caching layer: yiisoft/cache is a commodity PSR-16 ("simple cache") implementation. If a feature needs a cache, this is a "buy" (adopt) decision, not a build one — it removes the temptation to write a bespoke cache wrapper.
• Framework-agnostic infrastructure bets: Because it implements PSR-16, the interface is get/set/has/delete/clear against any backend (file, array, Redis, Memcached adapters exist in the Yii ecosystem). This supports decisions to keep caching behind an interface rather than coupling product code to a specific store.
• Feature-level performance work: Response/HTML fragment caching, expensive query result caching, computed-value memoization, and throttling counters are the concrete use cases this unlocks without new product surface area.
• Roadmap sequencing for performance initiatives: If the roadmap has "reduce p95 latency" or "cut DB load" items, a standards-based cache is an enabling dependency that can ship early and independently of larger architecture work.
• Vendor/exit-risk posture: BSD-3-Clause and PSR-16 mean near-zero lock-in — swapping to Symfony Cache, Laravel's cache, or a custom PSR-16 implementation is a one-line binding change. That de-risks the "which cache library" debate and lets the team move on.
• Important caveat for this specific evaluation: Despite the framing, this is a Yii ecosystem package, not a Laravel package. In a Laravel codebase, the correct product decision is almost always to use the framework's native Cache facade / illuminate/cache, which already provides PSR-16-compatible Cache::store()->... access plus tags, locks, and framework wiring. Adopting yiisoft/cache inside Laravel would add a dependency to duplicate existing capability — a net-negative decision unless there's a specific portability requirement.

When to Consider This Package

Consider it when:

• The application is built on Yii 2/3 or a framework-agnostic PHP service where no first-party cache abstraction is already in place.
• You specifically want a PSR-16 (simple cache) contract — a small, string-keyed get/set/delete surface — rather than the richer PSR-6 pool/tag model.
• You want a thin, permissively licensed (BSD-3) dependency with no framework gravity, so the cache layer stays swappable.
• Your caching needs are plain key-value with TTLs: fragment caching, config/API-response caching, memoizing expensive computations.
• You need a low-ceremony interface to mock in unit tests (the array/file adapters are trivial to substitute).

Look elsewhere when:

• You are on Laravel. Use illuminate/cache. It already satisfies PSR-16 via its store API, plus tags, atomic locks, and Cache::remember() ergonomics. Adding yiisoft/cache is redundant.
• You need cache tagging, hierarchical invalidation, or distributed locks — that's PSR-6/Symfony Cache territory, not PSR-16.
• Community support is a procurement criterion. 46 GitHub stars and a single-vendor maintenance model (Yii core team) means thin third-party knowledge base, few Stack Overflow answers, and bus-factor risk. For a critical-path dependency, that matters.
• You need long-term vendor SLAs or commercial support — not offered here.
• Your team is already standardized on Symfony Cache — mixing two cache abstractions adds cognitive load for no product benefit.

How to Pitch It (Stakeholders)

For executives (30 seconds): We need a caching layer to hit our latency and database-load targets. yiisoft/cache is a small, free (BSD-3), standards-compliant PHP caching library — it implements PSR-16, the industry-standard "simple cache" interface, which means we are not locked in: we can swap the underlying storage (files, Redis, memory) or replace the library entirely with a one-line configuration change. Cost is effectively zero, integration effort is days not weeks, and the risk of reversal is low. One caveat worth surfacing: this library comes from the Yii ecosystem, and our stack is Laravel. Laravel already ships an equivalent, richer cache capability. My recommendation is to treat this as a reference/fallback evaluation, and default to Laravel's native cache for the actual build — adopting a second cache library into a Laravel app would add maintenance surface without adding capability.

For engineering: PSR-16 is the whole value proposition — a tiny get/set/has/delete/clear contract with TTL support, backed by pluggable adapters (array, file, APCu, Redis, Memcached). It's clean to inject behind our own CacheInterface binding so tests use the array adapter. The tradeoffs are real: no tagging, no atomic locks, no bulk operations, and a small upstream community (≈46 stars, single-maintainer-ish). Under Laravel, Cache::store('redis')->remember(...) covers the same ground with first-party support and tagging — so the honest engineering recommendation is don't add this dependency to a Laravel service; evaluate it only if we're building framework-agnostic PHP components or moving toward Yii, where it's a natural fit.
