**A lightweight, type-safe dependency injection library for TypeScript.**

`ts-inject` simplifies dependency management in TypeScript applications by providing a straightforward and efficient way to inject dependencies, enhancing modularity and testability.

## ✨ Features

- **Type-Safe**: Leverages TypeScript's type system for compile-time safety.
- **Lightweight**: Minimal overhead with a focus on simplicity.
- **Flexible**: Supports various injection patterns to suit different needs.
- **Test-Friendly**: Facilitates easy mocking and testing of dependencies.

## 📦 Installation

```bash
npm install @michaelganchas/ts-inject
# or
yarn add @michaelganchas/ts-inject
```

## 📌 Where to Use

You can use `ts-inject` in any **TypeScript-based project** where clean architecture, testability, and modularity matter. Some common use cases include:

- **Modular backend applications** (e.g. Node.js with Express or Koa)
- **Domain-driven design (DDD)** implementations
- **Microservices** and **serverless functions**
- **CLIs and tooling** built with TypeScript
- **Unit testing** with easily mockable dependencies
- **Frontend apps** (e.g. React, React Native or Vue with TypeScript) that follow service-based architecture

> If you're tired of manually wiring dependencies or passing instances all over your codebase, `ts-inject` offers a clean, intuitive alternative.
