The Store Object

The store object provides methods to manage some state. You can trigger actions on the store to update the state as needed.

For a full reference on the state of the picker, read the API of the State Object.

Methods

addActor

Arguments	Returns
Actor	Action

Adds an actor to generate an action with the ability to update the store's state.

An "actor" is a method that receives the current state and a payload and then returns the next partial state to be applied.

An "action" is the method invoked with the payload which then triggers the "actor" with the current state.

const myStringActor = (state, payload) => {
  if (typeof payload.value === 'string') {
    return {
      someStateKey: payload.value,
    }
  }
}
const myStringAction = store.addActor(myStringActor)

With myStringAction above, it can be triggered it like this:

myStringAction({ value: 'cool' })

...to update the state's someStateKey value to 'cool'.

subscribe

Arguments	Returns
callback: Function	unsubscribe: Function

Subscribes to updates to the state.

The function returned can be called to unsubscribe to the updates.

const callback = () => {
  console.log('The state was changed!')
}
const unsubscribe = store.subscribe(callback)

getState

Arguments	Returns
none	Object

Gets the current state of the picker.

const state = picker.getState()
console.log(state) // '[object Object]'
