Mood is an elegant state machine you can use to model large number of problems, among which are UI state management, communication protocol design, language parsing, artificial intelligence and other engineering applications.
- Finite state machine: Use mood to perform predetermined sequence of actions depending on a sequence of events with which they are presented.
- Asynchronous: Mood plays well with your favorite libraries and use promises to transition from one state to an other.
Usage
import mood from 'mood'
// add transitions from constructor
const door = mood('init', {
'open' :
['lock', () => {
// do something when the current state is 'open'
// and on the 'lock' event
},'locked'],
'locked': [
['close', 'closed'],
['break', () => {
// do something when the current state is 'locked'
// and on the 'break' event
}, 'open']
]
})
// add new transition
// if transition returns promise, wait for promise to be resolved to trigger state change
door.add('closed', 'knock', function () {
return new Promise(resolve => setTimeout(resolve, 1000))
}, 'open')
// trigger open-lock transition
door.trigger('lock')
// trigger locked-break transition
door.trigger('break').then(state => {
// do something with new state
})
