About

This site is a catalog of Frontend Patterns — reusable solutions to recurring problems — together with the Libraries that implement them, the Skills that apply them, and the Blog posts that explore them.

A Pattern is more than a definition: it ships a Skill that applies, assesses, and refactors code toward it, and Guards that keep that code conformant over time. The aim is to help humans and AI agents produce high-quality code, fast.

Goals

Every Pattern earns its place by advancing at least one Goal — a quality of good code that justifies it. The Goals are these:

• Testability
  Behaviour can be pinned down and verified in isolation.
• Maintainability
  Change stays cheap as the code and the team grow.
• Comprehensibility
  Minimal cognitive load — a reader (human or AI) can hold the piece in their head.

About the author

I’m Bogdan Zaharia, a software developer with over 16 years across the stack. I spent my first years on the backend — Java, then Node.js — where I got hooked on design patterns, TDD, and clean architecture. Then I crossed over to the frontend and found that most of that craft hadn’t made the trip.

Frontend Patterns is my attempt to close that gap: adapting the architecture patterns I learned on the backend to the frontend stack, and packaging them so that both humans and AI agents can put them to work.
