asr-fsm-navigation

Given an fsm description of how users should be able to navigate between states:

Watches for dispatch and dispatchInput events, interprets the first argument to be the action type, and when it sees one it has a command for, it tells the abstract-state-router to navigate to that state (inheriting all parameters from the current state).

const asrFsmNavigation('asr-fsm-navigation') 
const makeAsrStateWatcher = require('asr-active-state-watcher')
 
const stateWatcher = makeAsrStateWatcher(stateRouter)
const startFsmNavigation = asrFsmNavigation(stateRouter, stateWatcher)
 
var stopNavigating = startFsmNavigation({
    'parent1': {
        GO_TO_PARENT2_CHILD1: 'parent2.child1',
        GO_TO_PARENT2_CHILD2: 'parent2.child2'
    },
    'parent2.child1': {
        GO_TO_PARENT1: 'parent1'
    },
    'parent2.child2': {
        GO_TO_PARENT1: 'parent1',
        GO_TO_PARENT1_CHILD2: 'parent1.child2'
    }
})

If the user is at the parent1.child1 state and dispatches a GO_TO_PARENT2_CHILD1 event, the module will navigate to the parent2.child1 state.

State navigation options

You can pass in an options object when you start the navigator. Defaults to { inherit: true }.

const startFsmNavigation = asrFsmNavigation(stateRouter, stateWatcher)
 
startFsmNavigation({
    'parent1': {
        GO_TO_PARENT2_CHILD1: 'parent2.child1',
        GO_TO_PARENT2_CHILD2: 'parent2.child2'
    },
    'parent2.child2': {
        GO_TO_PARENT1: 'parent1',
    }
}, {
    inherit: false
})

Querystring parameters

For each action, you can specify particular parameter values that will be set when navigating to the next state.

To do this, give an object with name/parameters parameters, instead of a string for a state destination:

const startFsmNavigation = asrFsmNavigation(stateRouter, stateWatcher)
 
startFsmNavigation({
    'parent1.child1': {
        GO_TO_PARENT2_CHILD1: {
            name: 'parent2.child1',
            parameters: {
                shiny: 'yes'
            }
        }
    },
    'parent2.child1': {
        GO_TO_PARENT1: 'parent1',
    }
}, {
    inherit: false
})
