XState is a TypeScript/JavaScript library for building state machines, statecharts, and actors. It enables deterministic, visual, and testable application logic for both frontend and backend environments.

Use cases

• model complex UI interactions with finite state machines
• orchestrate multi-step workflows in serverless functions
• manage application state in React, Vue, or Svelte projects
• visualize statecharts using Stately Studio
• implement robust event-driven logic in Node.js services
• create reusable actors for microservice communication

When to choose

• You need a predictable, testable way to handle complex state transitions.
• Your project uses TypeScript and benefits from strong type inference.
• You want visual tooling (Stately Studio) to design and simulate state machines.
• Zero runtime dependencies are important for bundle size.

When to avoid

• Your application has trivial state needs that can be handled by simple hooks or Redux.
• You prefer a purely functional or immutable data approach without explicit state machines.
• You need a solution that works out‑of‑the‑box with non‑JavaScript runtimes.
