TypeWire 0.1.0 — Explicit, Transparent DI for TypeScript

TL;DR: TypeWire is a small DI library for TypeScript — no decorators, no magic, just typed wires and explicit registration. Designed for clarity and composability as your system scales. In recent posts, I’ve been writing about architectural clarity — how good boundaries come from assigning clear ownership and avoiding ambient behaviors. That doesn’t just apply to services or classes — it also applies to how we wire them together. Constructors and factories are part of your system’s behavior. They may not drive core business logic directly, but they shape how that logic can be composed and reused. When we manually stitch them together across files and modules, boundaries blur. It’s not always obvious at first — but as the system grows, that blur often becomes expensive over time. We already have solutions to this problem — DI frameworks and libraries. But many come with known challenges and friction in practice. Given these known problems, TypeWire, is my attempt to experiment on solution to the problem. TypeWire is a small, transparent DI library for TypeScript — designed to formalize those boundaries.
