Product Decisions This Supports
Stack note: webman/cache is a cache component for the webman framework (Workerman/event-loop PHP), not Laravel. If the product runs on Laravel, this package is out of scope and the built-in illuminate/cache is the default answer. The assessment below assumes we are, or might become, a webman shop — for example a high-concurrency service, WebSocket gateway, or long-lived worker process where Laravel's request-per-process model is a poor fit.
For that context, this package informs these decisions:
- Build vs. buy for the caching layer. The alternative is writing our own cache wrapper around Redis/file/array drivers. This package is a thin, MIT-licensed abstraction with a conventional API. Buying (adopting) avoids a bespoke internal utility that we would own forever and that every new engineer would have to learn.
- Framework consolidation. If we standardize on webman for performance-sensitive services, we need a sanctioned answer to "where does caching go?" Providing one blessed component reduces the drift into three teams with three different Redis wrappers.
- Environment parity. A single API that swaps drivers (file/array in local dev, Redis in staging/prod) means fewer "works on my machine" cache bugs and cheaper ephemeral environments.
- Roadmap sequencing for caching-dependent features. Rate limiting, feature flags, hot-read caching of catalog/config data, and short-lived session-ish state all need a cache primitive before they can be planned. This package is the prerequisite, not the feature.
- Coupling and reversibility. Because the surface area is small and PSR-style, we can adopt it now and exit cheaply later. That makes it a low-regret decision that unblocks work without locking architecture.
When to Consider This Package
Adopt when all of these hold:
- The service is on webman/Workerman (or we've committed to it for a specific service), and caching must work inside a long-lived event-loop process rather than a per-request lifecycle.
- We need a uniform cache API across multiple drivers and want dev/prod parity without custom code.
- The caching requirements are basic: get/set/delete/TTL, maybe increment. No tagging, no cross-process invalidation semantics, no distributed locking.
- We can tolerate single-maintainer, low-adoption risk — pin the version, wrap it behind our own interface, and accept a replacement cost measured in hours, not weeks.
- We want to avoid inventing an internal utility that no one else will maintain.
Look elsewhere when:
- The product is on Laravel or Symfony — use the framework's native cache; adding a foreign component here is pure cost.
- We need advanced cache semantics: tag-based invalidation, cache stampede protection, atomic locks, cluster/sharding, serialization guarantees, or observable hit/miss metrics out of the box.
- We need vendor support, SLAs, or a security review trail. Three stars and zero dependents means we are effectively the first production user; every edge case is ours to find.
- Cross-worker consistency matters. Per-process in-memory drivers won't be shared across workers — if correctness depends on a single source of truth, we should go straight to Redis and skip the abstraction debate.
- The team has no webman experience. The savings from a thin cache component are dwarfed by the operational learning curve of the runtime.
How to Pitch It (Stakeholders)
To executives: This is a small, MIT-licensed caching component for our webman services. It costs nothing to license, replaces a utility we would otherwise build and maintain internally, and standardizes how caching is done across services. It is deliberately thin and replaceable — the decision is reversible at low cost, so it does not constrain future platform choices. The main caveat is maturity: it is a low-adoption package, so we treat it as an internal dependency with a pinned version and a documented fallback rather than a strategic platform bet.
To engineering: Adopt it as the sanctioned caching primitive for webman services, behind our own thin wrapper interface. That gives us one API, swappable drivers for local vs. production, and a one-day exit path to Symfony Cache or a hand-rolled Redis client if the package stalls or we hit its limits. Pin the version, own the wrapper, and do not let feature code call the package directly — treat the wrapper as the contract.
To the risk register: low blast radius, low switching cost, but real maintenance-concentration risk. Mitigation is the wrapper plus a quarterly check on release cadence; if releases stop, we fork or replace without touching product code.
