Getting Started

A simple Counter APP...

import Arbor from "arbor-store"
import timetravel from "arbor-timetravel"

const store = timetravel(new Arbor({
  todos: []
}))

// retrieves the current time cursor value
store.timeline.cursor

// goes back one time unit
store.timeline.travel.step(-1)

// move forward one time unit
store.timeline.travel.step(1)

// travels to a specific point in time
store.timeline.travel.to(5)

// goes back to the beginning of time
store.timeline.travel.origin()

// travels to the last state change (present)
store.timeline.travel.present()

State Tree Time Travel

Arbor leverages Structural Sharing in order to perform state mutations. A new state tree is always created by applying the minimum amount of operations necessary to generate the new state. With this, a series of state snapshots may be recorded. This packages leverages that behavior in order to provide time traveling features for Arbor based stores.
