FSM

FSM

A simple type-safe finite state machine. This is used internally to control the Order process, ensuring that the state of Orders, Payments, Fulfillments and Refunds follows a well-defined behaviour.

Signature
class FSM<T extends string, Data = any> {
constructor(config: StateMachineConfig<T, Data>, initialState: T)
initialState: T
currentState: T
transitionTo(state: T, data: Data) => Promise<{ finalize: () => Promise<any> }>;
jumpTo(state: T) => ;
getNextStates() => readonly T[];
canTransitionTo(state: T) => boolean;
}
