Session Interface Laravel Package

Product Decisions This Supports

• Build vs. buy for session contracts: This package is only an interface layer (Aura\Session\SessionInterface and related contracts) extracted from Aura.Session. It answers a narrow question — "do we need to own a session abstraction?" — rather than "how do we store sessions?" For a Laravel codebase, the answer is usually no: Illuminate\Contracts\Session\Session already exists, is documented, framework-integrated, and battle-tested.
• Framework-agnostic library strategy: The one decision this materially informs is whether a library you publish should depend on a concrete session implementation. If you're shipping a package that must run under Aura, Slim, or plain PHP without dragging in a framework, depending on an interface-only package is defensible — it keeps your composer graph clean and test doubles trivial.
• Testability and swappability: Consuming an interface instead of a concrete session object lets you inject fakes in unit tests and swap storage backends without touching call sites. This is a design-quality benefit, not a product feature; it should be weighed against the cost of adding an adapter on top of Laravel's session.
• Roadmap signal for multi-framework support: If a roadmap item is "make our core package usable outside Laravel," this package is a data point in the analysis — but a weak one, given zero dependents and no ecosystem evidence that anyone else chose this contract.
• Not supported: pricing, packaging, or feature differentiation decisions. Adoption here does not unlock capabilities; it only changes the shape of a dependency.

When to Consider This Package

Consider it when all of the following hold:

• You are building a framework-agnostic PHP library (not a Laravel application) that needs to accept a session object without committing to a storage implementation.
• You are already in or explicitly targeting the Aura ecosystem, or you need binary compatibility with code typed against Aura\Session\SessionInterface.
• You want an interface-only dependency with a negligible install footprint and no runtime code paths to audit.
• You accept MIT licensing and a very small surface area as sufficient governance.

Look elsewhere when:

• You're in Laravel. Use Illuminate\Contracts\Session\Session and the framework's session manager. Wrapping Aura's interface would require a custom adapter, add a translation layer, and gain nothing.
• You need actual session behavior. This package stores nothing. You'd need aura/session or another implementation, at which point you're adopting an entire library for one contract.
• You need vendor assurance. Zero stars, zero dependents, and no downstream consumers means no community validation, no third-party documentation, and an effectively single-maintainer bus factor. There is no visible security disclosure process.
• Your team is Symfony- or PSR-centric. symfony/http-foundation and PSR-7/PSR-15 middleware conventions already cover this ground with vastly larger ecosystems.
• You just need an interface. Defining a three-method session contract in-house is roughly an hour of work and removes an external dependency entirely — often the better PM call.

How to Pitch It (Stakeholders)

For executives: This is a tiny, MIT-licensed PHP interface package with no runtime behavior and no cost. It is not a session implementation and provides no user-facing capability. The strategic value is limited: it would only matter if we commit to shipping framework-agnostic PHP libraries. Given zero stars, zero dependents, and no downstream consumers, it carries no market validation — treating it as a strategic dependency would be over-reading a 500-line contract file.

For engineering: It's the extracted contract from Aura.Session — useful as a reference for what a clean session interface looks like, and viable as a dependency only in non-Laravel, Aura-adjacent contexts. In our Laravel codebase it is redundant with Illuminate\Contracts\Session\Session and would require a bespoke adapter. Recommendation: do not adopt as a dependency. Optionally vendor or mirror the interface shape if we build a portable library, but own the contract ourselves. This keeps our supply chain at zero new maintainers while preserving the design benefit.
