Argon Routing

Argon Routing is the HTTP routing layer that powers the Argon ecosystem.
It is designed around the Argon container, the shared middleware pipeline, and the request-handler resolver. The library embraces those components to provide:

• auto-registration of routes in the container;
• seamless middleware stack compilation;
• request handler resolution that honours Argon’s logging and pipeline stages.

Because of those tight integrations, Argon Routing is not intended for use outside the Argon stack. It has hard runtime dependencies on:

• maduser/argon-container (service container and service providers);
• maduser/argon-middleware (pipeline manager/store).

If you need a framework-agnostic router, you should look at an alternative.

Installation

Make sure your project already pulls in maduser/argon-container and maduser/argon-middleware; they are required at runtime. When developing locally inside the Argon monorepo, the path repositories configured there will resolve the packages automatically.

Quick Start

Middleware passed to the router can be concrete middleware service IDs or group aliases from the container's middleware.http tag metadata. Route metadata stores the resolved container service IDs, not the original aliases, so the cached route stack can be handed directly to maduser/argon-middleware. Those service IDs may be concrete middleware classes or interfaces bound in the container.

Once you hand the RouteManager instance to Argon’s middleware pipeline and request-handler resolver (see the main Argon documentation), requests will flow through the registered middleware stacks and invoke your controllers through the container.

Handler Contract

Container-backed routes support these handler definitions:

Route placeholders are forwarded to the container invocation as named arguments. Controller methods should declare those placeholders directly:

Do not expect a single array $args parameter in container-backed handlers. The container prepares controller invocations through reflection, so route arguments are mapped by name.

Not Found Contract

When no route matches the incoming request, RouteMatcher throws Maduser\Argon\Routing\Exception\RouteNotFoundException. The exception carries code 404, which lets Argon runtime error handlers render the failure as an HTTP not-found response instead of an internal-server-error.

Model / DTO Bindings via Interceptors

Frameworks such as Laravel or Symfony implement “route model binding” inside the router. In Argon the router keeps things agnostic: it forwards the raw route arguments (['user' => '42']) into the container, and interceptors take care of loading any richer objects you expect in your controllers.

Instead of hard-coding a single binding strategy in the router, this approach lets you decide how arguments should be turned into rich objects: one interceptor may hydrate entities from IDs, another may validate and map JSON payloads into DTOs, others could parse XML or JSON-RPC requests. Because interceptors are just classes registered with the container, you can combine and layer them however you like. See the Argon container README for more patterns and advanced usage.

Notes

• The InMemoryStore bundled with the package exists to keep tests simple and for early prototyping; production builds should rely on the container-backed store registered by the ArgonRoutingServiceProvider.
• The FileSystemStore is a placeholder for potential standalone usage. It is not required when running inside Argon.
• Shared interfaces (such as ResultContextInterface) now ship with maduser/argon-middleware packages; make sure your project is aligned with the versions shipped there.
