SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

UI behavior often becomes inconsistent as interactions grow, causing invisible or invalid states and confusing user feedback.

Core Features & Use Cases

  • Finite state modeling of UI components
  • Defining states, events, transitions, actions, and guards
  • Validation and predictable behavior across forms, data fetching, and authentication flows

Quick Start

Map a sample form flow (idle, editing, submitting, success/failure) to a state-machine and validate transitions.

FAQPage Schema
How do I prevent invalid UI states in a multi-step form wizard?

Modeling UI behavior as a finite state machine prevents invalid states by defining explicit states, events, transitions, and guards. This formalizes interactions to eliminate impossible states and stabilize complex form wizard behaviors.

What is a finite state machine used for in interaction design?

A finite state machine is used in interaction design to map UI component behavior through defined states, events, and transitions. This ensures predictable user feedback and reliable validation across web and mobile interfaces.

How do I model authentication flows to stabilize user interactions?

Model authentication flows by defining states, events, and transitions to stabilize interactions. This formalizes behavior and enables validation, ensuring predictable outcomes for authentication processes across platforms.

Can I use state machines for data fetching and onboarding UI flows?

Yes, state machines apply to data fetching and multi-step onboarding UI flows. Defining states, actions, and guards ensures predictable behavior and eliminates invisible invalid states during asynchronous operations.

Do I need defined transitions and guards to formalize UI behavior?

Yes, formalizing UI behavior requires clearly defined states, events, transitions, actions, and guards. This structure validates transitions and ensures reliable, predictable interactions across web and mobile applications.

Why does UI behavior become inconsistent as interactions grow?

UI behavior becomes inconsistent as interactions grow because unstructured logic creates invisible or invalid states. Mapping flows to a state machine formalizes behavior and provides validation to stabilize user feedback.
