Actors

Learn how to use actors and the actor model in XState and Stately Studio.

• Actors

  When you run a state machine, it becomes an actor: a running process that can receive events, send events and change its behavior based on the events it receives, which can cause effects outside of the actor.

• Invoke

  XState is based on the actor model. Invoked actors are managed by the state machine. Invoked actors are created and started when the state is entered, and stopped when the state is exited.

• Spawn

  XState is based on the actor model. Spawned actors are managed by the state machine.

• Systems

  An actor system is a collection of actors that can communicate with each other. Actors can invoke/spawn other actors, which forms a natural hierarchy of actors that belong to the same system.
