samber/do is a dependency injection toolkit for Go 1.18+ built on generics, offering a type-safe, reflection-free API with no external dependencies. It provides service registration and invocation, scope trees, health checks, graceful shutdown, and dependency graph debugging tools including a Web UI.

Use cases

• wire up services in a Go application with compile-time type safety
• replace uber/dig or uber/fx with a generics-based DI container
• manage service lifecycle with health checks and graceful shutdown
• organize services into scoped modules with visibility control
• visualize and debug a service dependency graph
• avoid code generation steps like google/wire in the build pipeline

When to choose

• you want compile-time-checked dependency resolution without a build step
• you need built-in health checks and dependency-aware graceful shutdown
• you want zero external dependencies and no reflection
• you need runtime flexibility like conditional registration, overrides, and scopes

When to avoid

• you want zero runtime cost and a fully static graph (use google/wire)
• you're building a large modular app that benefits from uber/fx's batteries-included framework
• you prefer a minimal reflection-based container to build your own framework on (use uber/dig)
