## What it is
A Go library providing reflection-based dependency injection. It builds and wires object graphs automatically using struct tags, supporting singletons, named and private instances.

## Use cases
- wire dependencies in a large Go application automatically
- build an object graph with dependency injection in Go
- avoid manual singleton wiring in Go services
- inject dependencies via struct tags in Go

## When to avoid
- you prefer compile-time or code-generated dependency injection
- you need an actively maintained library - the repo is archived since 2019

## Facets
