Multiplatform dependency injection library explores concepts through blog posts. Features core DI functionality, integration with Android, Compose, ViewModel, and coroutine context handling. Not for production use.
This library should not be used in production. It was made from a series of blog posts on creating a Kotlin Dependency Injection Library. You can find all the posts here.
A multiplatform Dependency Injection library.
implementation("dev.scottpierce:kinject-core:<latest version here>")| Artifact | Description |
|---|---|
| kinject-core | Provides core DI functionality. |
| kinject-android | Provides helper methods for working with ObjectGraphs embedded in Contexts, and helper classes for embedding ObjectGraphs in Contexts. |
| kinject-android-appcompat | Provides KinjectAppCompatActivity. |
| kinject-android-compose | Provides KinjectComponentActivity. |
| kinject-compose | Provides the ability to provide an ObjectGraph in a Compose hierarchy. |
| kinject-compose-viewmodel | Provides the ability to get a ViewModel in a compose hierarchy. |
| kinject-compose-voyager | Provides the ability to get a ScreenModel in a compose hierarchy. |
| kinject-coroutines | Provides a KinjectCoroutineContextElement, to easily allow passing an ObjectGraph via a CoroutineContext. |
| kinject-viewmodel | Provides the ability to declare a view model dependency, and a factory to create it. |
Dependencies:
class A
class B(val a: A)
class C(
val a: A,
val b: B,
)Usage:
val graph = objectGraph {
singleton(A()) // Provided Binding
singleton { B(a = get()) } // Lazy Binding
singleton { C(a = get(), b = get()) } // Lazy Binding
}
val a: A = graph.get()
val b: B = graph.get()
val c: C = graph.get()ObjectGraphs can be added together to scope dependencies. After adding a graph, all of it's
dependencies become accessible to the new graph.
val graph1 = objectGraph {
singleton(A())
singleton { B(a = get()) }
}
val graph2 = objectGraph {
add(graph1) // Add the first graph 2 this graph
singleton { C(a = get(), b = get()) } // Now we can access all of the first graphs dependencies
}
val a: A = graph2.get()
val b: B = graph2.get()
val c: C = graph2.get()This library should not be used in production. It was made from a series of blog posts on creating a Kotlin Dependency Injection Library. You can find all the posts here.
