Simple FSM implementation.
Define state machine like this
const actions = {
plus1: n => (n + 1),
};
const stateMap = {
// define initial status and state
// state can be object or anything..
start: {
status: 'init',
state: 0,
},
states: {
// states keys are status name
init: {
// action names, value can be string or function
// if == string => string is next status
// if == function => function() is next status
plus1: 'plused'
},
plused: {
plus1: (v) => {
if(v >= 10) return 'dead';
return 'plused';
},
},
dead: { },
}
}Create a new FSM instance
const FSM = makeFSM(stateMap, actions);Get current FSM status.
Get current FSM state.
Get available actions for current status.
Do action.
