Robot (robot3) is a small (~1KB) functional and immutable finite state machine library for JavaScript. It brings declarative state management to UI applications with integrations for React, Preact, Haunted, and other frameworks.

Use cases

• manage complex UI state with finite state machines
• model toggle, loading, and async states declaratively
• prevent invalid states in frontend components
• use a state machine with React or Preact via hooks
• handle async invocations and context in application state
• replace boolean flags with explicit state transitions

When to choose

• you want a tiny, dependency-free state machine library
• you prefer a functional API over options objects
• you need declarative state management for UI components
• you use React, Preact, or Haunted and want machine integration

When to avoid

• you need a full-featured statechart solution with actors and hierarchical states
• your team prefers Redux-style global stores
• you need server-side or non-JavaScript state machine tooling
