assemble — Pragmatic Dependency Injection for Go

assemble is a pragmatic, lightweight dependency injection (DI) library for Go.
It focuses on clarity, type safety, and zero reflection through a combination of runtime and generated dependency graphs.

Key Features

• 🧩 Strongly typed DI container — safe, reflection-free dependency resolution
• ⚙️ Static code generation: compile-time wiring for performance and safety
• 🔄 Lifecycle hooks: OnStart, OnStop, plus type-aware OnStartFor[T] / OnStopFor[T]
• 🧠 Deterministic startup and shutdown based on creation order and priorities
• ⏱️ Timeouts and multi-error aggregation for clean lifecycle management
• 🧭 Graph export (DOT / PlantUML) for visualizing dependency and shutdown order
• 🧰 Designed for modular services, CLIs, and testable applications
