Psr7 Laravel Package

Product Decisions This Supports

• Build vs. buy for HTTP message plumbing. PSR-7 (Request, Response, Stream, Uri, UploadedFile) is commodity infrastructure. This package lets you consume a spec-compliant implementation instead of hand-rolling message objects and stream handling — a decision that should almost always resolve to "buy/consume" unless you have unusual performance constraints.
• Roadmap: interoperability as a feature. Adopting PSR-7 is a prerequisite for PSR-15 middleware and for third-party libraries (routing, auth, CORS, rate limiting, logging, OpenAPI tooling) that type-hint PSR-7 rather than a framework-specific request. If your roadmap includes "ecosystem middleware" or "drop-in integrations," this is an enabling dependency, not a headline feature.
• Framework and runtime portability. For services built on Workerman/webman, PSR-7 compatibility reduces the cost of migrating handlers, tests, or gateway components to another runtime later, and lets the same handler code run behind both async and traditional stacks.
• API gateway / BFF and proxy use cases. Message-centric HTTP abstractions are the right primitive for request/response transformation, header manipulation, and upstream proxying — areas where you want to reason about messages, not framework controllers.
• Testability and contracts. PSR-7 request/response doubles make handler tests deterministic and decouple test fixtures from the server runtime. This supports a "definition of done" that includes handler-level tests without booting an event loop.
• Vendor-risk containment. Choosing a PHP-FIG interface as the internal contract means the concrete implementation (this package vs. alternatives) becomes swappable — a deliberate architectural hedge.

When to Consider This Package

Consider it when:

• You are already on Workerman or webman and want PSR-7 messages without introducing a second, unrelated HTTP stack.
• You need a thin, MIT-licensed PSR-7 implementation maintained by the Workerman author — trust here derives from the parent project, not from the package's own adoption.
• Your requirements are message objects and streams only; you are not expecting PSR-17 factories, PSR-15 dispatchers, or a middleware runtime from this dependency.
• You want minimal surface area and no transitive dependency sprawl in a latency-sensitive service.

Look elsewhere when:

• Adoption evidence matters. 10 stars, zero recorded dependents, and a composite score of 0.08 are weak external validation signals. If your organization gates dependencies on community size or a security review with a documented user base, expect friction — be prepared to justify it as a first-party-adjacent component of the Workerman ecosystem rather than an independent library.
• You are not on Workerman. Outside that runtime there is no reason to prefer this over nyholm/psr7, guzzlehttp/psr7, or laminas-diactoros, all of which have far deeper integration documentation and downstream usage.
• You need the full PSR-17 factory set to construct messages generically, or you are standardizing on PSR-15 middleware pipelines; evaluate a stack that ships those natively.
• Bus factor and long-term support are gating concerns. A single-maintainer, low-visibility package in your critical path warrants pinning, an internal fork/exit plan, or a wrapper interface so replacement is a one-file change.
• You need documented production case studies to satisfy architecture review; none are likely to exist at this adoption level.

How to Pitch It (Stakeholders)

To executives: This is a small, MIT-licensed standards component, not a platform commitment. It buys us PHP standard-compliant HTTP messages so our services can use off-the-shelf integrations and so our code is portable across runtimes. Cost is near zero, lock-in is low because the contract is a public standard rather than a vendor API, and it supports the roadmap theme of "integrate with the broader PHP ecosystem instead of building bespoke plumbing." The honest caveat: the package itself is lightly adopted, so we should treat it as a component of the Workerman ecosystem we already depend on, keep it version-pinned, and isolate it behind our own interface so it can be swapped without product impact.

To engineering: Treat this as a thin adapter, not a framework. Consume it where you're already inside Workerman and need PSR-7 messages; wrap it behind an internal boundary so nyholm/psr7 or guzzlehttp/psr7 is a drop-in replacement if maintenance stalls. Expect no PSR-17 factories or middleware runner here — plan those separately. Verify PHP version support and stream behavior against our actual workloads (large uploads, chunked responses) before it lands in a hot path, and add a handler-level test suite to make the swap cheap.
