Details ------- [](#details) Use this interface to enhance your services, such that a dependency graph can be built. This paves the way for many features, including: 1. Visualization of a dependency graph of all application services. 2. Notification if a dependency is unfulfilled. 3. Suggestion of module packages that may fulfill unmet dependencies. Use together with [`dhii/services`](https://github.com/Dhii/services) to enhance your services with convenient shorthands and type information. Rationale --------- [](#rationale) The current signature of a service is just a callable of form `(ContainerInterface $c) => mixed`. This describes the service itself, and allows it to draw dependencies from the container. However, in order to know what other services are being used by any particular service definition, that definition must first be invoked. This means that as things currently are, it is not possible to build a map of all service relationships without actually executing them all. The solution is to make services aware of and able to expose the names of other services that it depends on. This way, it is possible to make quite a uniform algorithm that can record all of these relationships, and and build a complete graph of all services and their dependencies. This opens up new possibilities for detection and automation. An implementation such as [`Factory`](https://github.com/Dhii/services/blob/0.1.x/src/Factory.php) can declare its dependencies, and automatically resolve them before passing them to the service definition, making it possible to describe the types that the dependencies are expected to be. This also cuts on the amount of code to be written, removing not only type checks/assertions, but also the calls to `$c->get()`. At the same time, this approach re-enforces strictness, because a service definition no longer has the choice of retrieving or not retrieving its dependencies: all dependencies are declared and necessarily resolved before the definition has a chance to do anything. This makes graphs more stable, and creates less opportunity for hidden dependencies that may not show otherwise, such as if simply recording all service names retrieved from the container. The `withDependencies()` method enables [multi-boxing](https://github.com/Dhii/services#multi-boxing), which allows the same service provider to be re-used multiple times in the same application - perhaps with different prefixes. This avoids not only the need for manual re-declaration of already defined services, but also has the potential for solving the service name collision problem, and it's no longer necessary to come up with clever prefixes for service names *in providers*, but shifts a part of the responsibility to the application. This is good, because it further re-enforces the notion that the application is in control - similarly to how the application decides which services override which, how the providers are discovered and loaded, etc. ### Health Score 22 — LowBetter than 22% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity7 Limited adoption so far Community7 Small or concentrated contributor base Maturity46 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
