createLiteMachine<S, E>(definition, initial): object

createLiteMachine<S, E, C>(definition, initial, initialContext): object

Creates a lightweight finite state machine (no trySend, no @zygos/option dependency).

Type Parameters​

S: S extends string​

Union of state names

E: E extends string​

Union of event names

C: C​

Context type

Parameters​

Overload 1:

definition: MachineDefinition<S, E, undefined>​

The state/transition map

initial: S​

The initial state

Overload 2:

The state/transition map

initial: S​

The initial state

initialContext: C​

The initial context value
