Features

• Finite State Machine Engines - Provides a deterministic engine that processes events through a predefined graph of states and transitions.
• Statechart Logic Libraries - Provides a formal statechart logic library and finite state machine framework for modeling complex application behavior.
• State Machines - Provides a comprehensive framework for defining states, events, and transitions to govern system behavior.
• Frontend State Management - Maintains predictable application data and UI synchronization through event-driven transitions and reactive snapshots.
• Visual State Machine Editors - Includes a visual editor to design state machine diagrams that automatically generate the corresponding logic and code.
• Actor Models - Implements an actor model for managing independent concurrent entities that communicate via asynchronous events.
• Actor Models - Implements an actor model to manage independent stateful entities that communicate via asynchronous message passing.
• Event-Driven Architectures - Uses event-driven architecture to update system configurations by matching incoming triggers against defined transition rules.
• Statecharts - Implements statecharts with hierarchical states and parallel regions for modeling complex system logic.
• State Transition Models - Allows for the definition of complex system behaviors using declarative state and transition models.
• Statechart Orchestration - Coordinates complex state transitions and orchestration using statecharts and actors to manage intricate behavioral flows.
• Event-Driven State Managers - Updates a central state object using event-driven transitions to ensure predictable data changes.
• Reactive State Management - Provides immutable representations of the current state as reactive snapshots for UI synchronization.
• Lifecycle Management - Provides mechanisms to start and manage the lifecycle of actors to provide reactive state snapshots.
• State Subscriptions - Allows components to connect to actor references and reactively track state changes.
• Event-Based Stores - Maintains a lightweight event-based store for data management using strong type inference.
• Persistent Application State - Supports saving and restoring the current state of system actors to maintain continuity across sessions.
• State Logic Visualizers - Includes a visual editor to create state machine diagrams that automatically generate corresponding logic and code.
• Asynchronous Task Orchestrators - Coordinates asynchronous tasks and side effects that execute in tandem with state transitions and actor lifecycles.
• Schema-Based State Validation - Verifies that event payloads and state changes adhere to a predefined contract during runtime execution.
• Side Effect Handlers - Schedules asynchronous tasks or secondary events to execute immediately after a state transition completes.
• Deterministic Queuing - Schedules asynchronous actions to execute only after a state transition has successfully completed.
• Reactive State Synchronization - Extracts specific data slices using reactive selectors to synchronize state with component frameworks.
• Visual State Logic Design - Provides tools to design state machine diagrams that generate executable code for complex behaviors.
• State Management - State machines and statecharts for complex logic.
• Alternative State Management - Orchestrates complex app logic using actor-based state machines.
