SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Offer practical patterns to manage state in React prototypes without heavyweight libraries.

Core Features & Use Cases

Standard reducer shape: Common state and action patterns.
Separation layers: Data, UI, and derived state patterns.
Minimal state machine helper: Simple, explicit transitions.

Quick Start

Start with a simple useReducer-based state pattern, then evolve with more patterns as needed.

FAQPage Schema

How do I manage state in React prototypes without adding heavy libraries?▼

Use useReducer with standard reducer patterns to manage state in React prototypes. This approach organizes state across data, UI, and derived values without requiring external state-management libraries, keeping your prototype lightweight and explicit.

What's the best way to structure state and actions in a React reducer?▼

Follow standard reducer shapes with explicit action unions and pure reducers that separate data, UI state, and derived state into distinct layers. This structure makes state transitions predictable and easier to test and maintain.

How do I handle derived state in React without recalculating on every render?▼

Separate derived-state computation into its own layer within your reducer pattern. Calculate derived values once during state updates rather than during render, following explicit rules to keep performance efficient and logic centralized.

Can I use context with reducer patterns for feature-scoped state in React?▼

Yes. Combine useReducer with React Context to scope state to specific features in your prototype. This keeps state organized by feature without requiring a state-management library while maintaining clear action and reducer boundaries.

What patterns work for simple state machines in React prototypes?▼

Use minimal state-machine helpers built on top of useReducer to define explicit transitions between states. This keeps state logic simple and readable while preventing invalid state combinations in your prototype.

When should I move from prototype state patterns to a dedicated library?▼

Stick with reducer patterns as long as your prototype has manageable state complexity. Move to a dedicated library when you need advanced features like time-travel debugging, middleware, or when state logic becomes difficult to follow across many reducers.
