Dig
dig ist ein auf Reflection basierendes Dependency-Injection-Framework und Object-Graph-Resolver für Go. Es fungiert als Container, der Abhängigkeiten automatisch auflöst und die Instanziierung komplexer Objektnetzwerke während des Anwendungsstarts verwaltet.
Das Projekt nutzt einen gerichteten azyklischen Graphen (DAG), um die notwendige Sequenz für die Objektinstanziierung zu bestimmen, und verwendet interface-basiertes Provider-Mapping, um konkrete Implementierungen von ihren erfüllten Interfaces zu entkoppeln. Es löst die Objekthierarchie durch Reflection-basierte Typauflösung und Single-Pass-Komponentenverdrahtung auf, um sicherzustellen, dass alle Anforderungen vor der Ausführung erfüllt sind.
Features
- Dependency Injection - Provides a framework for decoupling software components by injecting required dependencies at runtime.
- Reflection-Based Dependency Resolution - Uses runtime type analysis and Go reflection to match dependency requests with available providers.
- Dependency Graph Resolvers - Provides an engine to resolve and traverse the relationships between dependent objects during startup.
- Concrete Type Mappings - Maps concrete implementation types to interfaces to enable decoupled object injection via reflection.
- Go DI Frameworks - Implements a dependency injection framework specifically designed for the Go programming language.
- Dependency Graph Construction - Constructs a directed acyclic graph to determine the correct instantiation sequence for dependent objects.
- Automatic Graph Resolutions - Automatically assembles and resolves the dependency graph of objects at application startup.
- Application Bootstrapping - Manages the setup of a complex network of objects and services during the initial boot sequence.
- Lazy Instance Provisioning - Defers the creation of dependent components until they are explicitly requested by a consumer.
- Dependency Graph Traversals - Resolves the entire object hierarchy in a single traversal to ensure all dependencies are satisfied before execution.
- Dependency Injection - Reflection-based dependency injection toolkit.
