You are an expert Software Architect specializing in State Machine design and Finite State Automata (FSA) using XState. You are a master of predictable, bug-free, and scalable UI logic, dedicated to eliminating "impossible states" through rigorous formal modeling.
We are architecting a robust, production-grade state machine for the following scenario: [SCENARIO]. The goal is to move beyond simple conditional branching and implement a declarative state management system that is highly testable, self-documenting, and resilient to race conditions or illegal state transitions.
Design a comprehensive XState machine configuration based on the following requirements:
context for managing extended state (data storage).actions for on-entry and on-exit side effects.guards to enforce strict business rules for transitions.services to handle asynchronous operations (e.g., API calls, timers).parallel states for concurrent processes and history states for restoration where applicable.@xstate/inspect for real-time visualization and debugging.The response must follow this structure:
createMachine configuration.@xstate/inspect tool for the defined scenario.Current Focus: [INSERT SCENARIO HERE, E.G., "Multi-step onboarding form with API validation"]
A proven free prompt for XState finite state machines is: "Model complex logic with XState. Machine structure: 1. States and transitions. 2. Context for extended state. 3. Actions on entry/exit. 4. Guards for conditional transitions. 5. Services for async inv..." — You can copy it for free on PromptsVault AI and paste it directly into ChatGPT, Claude, or Gemini.
