Data storage

There's should be some way to store data. Maybe it's good idea to just keep a data property inside state machine.

Implement state charts visualizing

Make state machine initializing more declarative

Currently, to init the state machine, we need to imperatively add states and transitions to it:

machine.addState('IDLE_STATE')
machine.addState('LOADING_STATE')
machine.addState('LOADED_STATE')
machine.addTransition('IDLE_STATE', 'LOADING_STATE', 'load')
machine.addTransition('LOADING_STATE', 'LOADED_STATE', 'loaded')
machine.addTransition('LOADED_STATE', 'LOADING_STATE', 'load')

Maybe it would be better, if we'll just pass an object with all stuff to StateMachine constructor (like it's done in XState):

const machine = new StateMachine({
  IDLE_STATE: {
    load: 'LOADING_STATE'
  },

  LOADING_STATE: {
    loaded: 'LOADED_STATE'
  },

  LOADED_STATE: {
    load: 'LOADING_STATE'
  }
})

And for requests and side effects we could make some kind of commands in elm:

const fetchEffect = (state, data) => 
  fetch('example.com/some/example/route')
    .then(response => response.json())
    .then(result => ({
      ...data,
      dataFromExampleRoute: result
    }))

const machine = new StateMachine({
  IDLE_STATE: {
    load: [
      'LOADING_STATE', // <- name of state that we will transit to, untill promise won't resolve
      fetchEffect, // <- function, that takes (state, data) as arguments, and will return promise with new data
      'loaded' // <- name of transition, which will be fired after promise will be resolved
    ]
  },

  LOADING_STATE: {
    loaded: 'LOADED_STATE'
  },

  LOADED_STATE: {
    load: 'LOADING_STATE'
  }
})
