XState: Predictable UI State with State Machines

Source: stately.aiadvanced

XState treats UI logic as a formal state machine, making impossible states impossible. It's ideal for complex components like multi-step forms or data fetching UIs. The footgun is overusing it for simple boolean toggles, which adds needless boilerplate.

XState models your UI's behavior as a formal state machine, making impossible states truly impossible. Think of it as a strict flowchart for your component's logic where only predefined events can cause transitions between states like 'loading' or 'success'. This is perfect for managing complex forms or robust data fetching components. The main footgun is applying it to simple state; using a machine for a basic counter is often overkill and introduces unnecessary complexity.
