|
## Context and Problem Statement
|
||
|
|
|
||
|
|
The application consists of many components (config, crypt, workspace, etc.) that depend on each other. We need a consistent way to manage these dependencies and allow for easy testing.
|
||
|
|
|
||
|
|
## Decision Drivers
|
||
|
|
|
||
|
|
* Testability.
|
||
|
|
* Modularity.
|
||
|
|
* Ease of service registration.
|
||
|
|
* Clear lifecycle management.
|
||
|
|
|
||
|
|
## Considered Options
|
||
|
|
|
||
|
|
* Global variables/singletons.
|
||
|
|
* Dependency Injection (DI) container.
|
||
|
|
* Manual Dependency Injection.
|
||
|
|
|
||
|
|
## Decision Outcome
|
||
|
|
|
||
|
|
Chosen option: "Service-Oriented Architecture with Dual-Constructor DI". Each service follows a pattern where it provides a `New()` constructor for standalone use/testing (static DI) and a `Register()` function for registration with the `Core` service container (dynamic DI).
|
||
|
|
|
||
|
|
### Positive Consequences
|
||
|
|
|
||
|
|
* Easy to unit test services by passing mock dependencies to `New()`.
|
||
|
|
* Automatic service discovery and lifecycle management via `Core`.
|
||
|
|
* Decoupled components.
|
||
|
|
|
||
|
|
### Negative Consequences
|
||
|
|
|
||
|
|
* Some boilerplate required for each service (`New` and `Register`).
|
||
|
|
* Dependency on `pkg/core` for `Register`.
