Introduction
Frontend teams often debate Redux vs Jotai vs Zustand.
The real problem is not which library you choose — it’s how hard it is to change later.
This article demonstrates a compile-time state swap pattern using a frontend template I built, validated with a real demo app.
The Usual Problem
In most projects:
- UI components import store-specific hooks
- Business logic leaks into reducers or atoms
- Changing state libraries means rewriting half the app
That is not scalable.
The Core Idea
UI should depend on contracts, not implementations.
In this template:
- UI consumes a single useCounter() hook
- That hook is the only swap boundary
- Redux and Jotai both conform to the same outward shape
{
count: number
increment(): void
decrement(): void
}
No UI changes.
No page-level changes.
No runtime assumptions.
State Swap in Action
The demo app contains:
- One Counter page
- One hook boundary
- Two implementations:
- Redux Toolkit
- Jotai
Swapping engines means changing one import, nothing else.
- Template Repo: Frontend Foundation Template Kit
- State Swap Demo: State Management Swap Demo App
Why This Matters in Real Teams
This pattern:
- Reduces long-term technical risk
- Makes architectural decisions reversible
- Allows teams to adopt new libraries safely
- Fits enterprise and startup codebases alike
Closing Thoughts
Libraries will change. Frameworks will evolve.
Your architecture must survive those changes.
This template is my attempt to codify that principle. If this resonates, I’d love to hear your thoughts.
