@wluwd/toolkit

A collection of proven, type-safe utilities built from real production needs.

This repository contains small, focused packages that have earned their place through actual usage. Nothing here is theoretical — each tool originated in real projects, solved real problems, and has been refined over time.

All packages are:

• 📦 Type-safe — full TypeScript support with accurate inference
• ✅ Production-tested — used in real-world codebases
• 🪶 Lightweight — zero or minimal dependencies
• 🔄 Modern runtime — ESM-only, targets current Node.js LTS

Philosophy

We publish what works. Packages land here once they’ve demonstrated reliability, clarity of API, and long-term usefulness.

These tools exist because they solved real problems. If they help you too, that's the goal.

Packages

Currently included:

• @wluwd/variations - Generate cartesian product variations of object properties for exhaustive testing and configuration matrices

Installation

Each package is installable independently:

npm install @wluwd/package-name

pnpm add @wluwd/package-name

yarn add @wluwd/package-name

Development

This is a monorepo managed with pnpm workspaces.
