do - Dependency Injection **⚙️ A dependency injection toolkit based on Go 1.18+ Generics.** This library implements the Dependency Injection design pattern. It may replace the fantastic package. uses Go 1.18+ generics and therefore offers a type‑safe API. **See also:** • samber/ro: Reactive Programming for Go: declarative and composable API for event-driven applications • samber/lo: A Lodash-style Go library based on Go 1.18+ Generics • samber/mo: Monads based on Go 1.18+ Generics (Option, Result, Either...) • samber/cc-skills-golang: AI Agent Skills for Golang ---- 💖 Sponsored by: DBOS - Durable workflow orchestration library for Go ---- **Why this name?** I love the **short name** for such a utility library. This name is the sum of and and no Go package uses this name. 💡 Features • **📒 Service registration** • Register by type • Register by name • Register multiple services from a package at once • **🪃 Service invocation** • Eager loading • Lazy loading • Transient loading • Tag-based invocation • Circular dependency detection • **🧙‍♂️ Service aliasing** • Implicit (provide struct, invoke interface) • Explicit (provide struct, bind interface, invoke interface) • **🔁 Service lifecycle** • Health check • Graceful unload (shutdown) • Dependency-aware parallel shutdown • Lifecycle hooks • **📦 Scope (a.k.a module) tree** • Visibility control • Dependency grouping • **📤 Container** • Dependency graph resolution and visualization • Default container • Container cloning • Service override • **🧪 Debugging & introspection** • Explain APIs: scope tree and service dependencies • Web UI & HTTP middleware (std, Gin, Fiber, Echo, Chi) • **🌈 Lightweight, no dependencies** • **🔅 No code generation** • **😷 Type‑safe API** 🚀 Install This library is v2 and follows SemVer strictly. No breaking changes will be made to exported APIs before v3.0.0. This library has no dependencies except the Go std lib. 🔥 Migration from v1 to v2 Documentation here 🤠 Documentation • GoDoc: https://godoc.org/github.com/samber/do/v2 • Documentation • Examples • Project templates 🎬 Project boilerplate • do-template-api • do-template-worker • do-template-cli 🤝 Contributing • Ping me on Twitter @samuelberthe (DMs, mentions, whatever :)) • Fork the project • Fix open issues or request new features Don't hesitate ;) 👤 Contributors 💫 Show your support Give a ⭐️ if this project helped you! 📝 License Copyright © 2022 Samuel Berthe.
