ContainerDI

ContainerDI is a dependency injection (DI) framework for Go (Golang). It provides a compile-time safe and type-safe way to manage dependencies within an application. The primary goal of ContainerDI is to reduce boilerplate code often associated with manual dependency management and to improve the overall structure and testability of Go applications.

It works by defining a container that holds and manages the instantiation of various objects, referred to as "providers." Developers define these providers, specifying how to create and configure the objects they represent. The container then resolves these dependencies based on their types. ContainerDI emphasizes compile-time checks, meaning many potential dependency issues are caught during the build process rather than at runtime, leading to more robust software.

Key features include the ability to declare dependencies using generic types, which enhances type safety. It also supports features like constructor injection and setter injection. The framework aims to be performant and minimize overhead, making it suitable for various application sizes and complexities. ContainerDI is often chosen by developers looking for a more structured approach to managing object lifecycles and inter-component relationships in their Go projects.
