TypeWire 0.1.0 — Explicit, Transparent DI for TypeScript
- TypeWire 0.1.0 is a DI library for TypeScript that promotes clarity and composability as systems scale, without decorators or magic, focusing on explicit registration and typed wires.
- It addresses the challenge of maintaining clear boundaries in systems by formalizing dependency injection and construction behavior, shifting ownership to individual wires.
- TypeWire avoids heavy decorator usage and tight coupling to frameworks, offering declarative type definitions and clear boundaries between resolution, behavior, and configuration.
- Each wire in TypeWire exposes methods for dependency instance retrieval and application, allowing use with compatible DI frameworks.
- By eliminating guesswork and inference via decorators, TypeWire emphasizes types and functions for a more natural DI modeling tool.
- Example code demonstrates how to define and use wires for services like UserService and UserController, emphasizing explicit registration and separation of concerns.
- TypeWire allows easy override of dependencies for testing purposes, promoting explicit mocking without complex setup.
- It supports various instantiation patterns like classes, factory functions, and async constructors, helping formalize system glue as complexity grows.
- TypeWire builds on architectural clarity themes and series by the author, offering a transparent and stable solution, suited for TypeScript projects.
- Feedback is welcome from developers dealing with messy construction logic, blurry service boundaries, or complex DI scenarios, with the project available on GitHub.
