xstate
XState facilitates seamless management of complex logic in JavaScript and TypeScript applications through event-driven programming and actor-based state management. It employs state machines and the actor model for predictable and visual state management, suitable for both frontend and backend usage without dependencies. Users can create and visualize state machines in Stately Studio and explore integration templates for React, Vue, and Svelte. The tool supports collaboration through VS Code extensions and offers extensive documentation and community support.
