Quick Start
npm install xstateDetailed Introduction
XState is a powerful, zero-dependency library designed to manage and orchestrate complex application logic using state machines, statecharts, and the actor model. It provides a structured, event-driven approach to handle application and workflow states, making logic predictable, robust, and easier to visualize. By modeling logic as actors and state machines, developers can create highly maintainable and scalable applications across both frontend and backend JavaScript/TypeScript environments.
