godi Documentation

godi brings type-safe dependency injection to Go with zero magic. Start simple, scale seamlessly.

Quick Start

// 1. Register your services
services := godi.NewServiceCollection()
services.AddSingleton(NewLogger)
services.AddScoped(NewUserService)

// 2. Build the container
provider, _ := services.BuildServiceProvider()
defer provider.Close()

// 3. Use your services
userService, _ := godi.Resolve[*UserService](provider)

That’s it! No annotations, no reflection magic, just functions.

Why godi?

• ✅ Never update constructors everywhere - Change once, godi handles the rest

• ✅ Perfect for web apps - Request isolation with scopes

• ✅ Testing made easy - Swap implementations instantly

• ✅ Start simple - Use only what you need

• ✅ Type-safe - Compile-time checking with generics
