After enough production projects, you realize most of us keep rebuilding the same infrastructure over and over: database connections that don’t fall over under load, auth that doesn’t get weird six months later, Docker configs that aren’t massive for no reason.

The usual options haven’t felt great to me:

* Copy something from an old project and hope the mistakes don’t come along with it * Piece things together from blog posts that may or may not still be relevant * Install another dependency and inherit its upgrade path forever

So I built Sinew.

It’s a registry of infrastructure patterns—not a framework, not a library. Just curated, tested code you copy directly into your project. You own it, you can read it end-to-end, and you can change it without fighting an abstraction.

There are 30+ patterns across areas like database setup, auth, caching, payments, monitoring, testing, and deployment.

CLI: npm install -g sinew

This is mostly for people who like understanding their infrastructure instead of outsourcing it to packages.
