react-immutable-js-store v0.0.1

react-immutable-js-store

React wrapper around immutable-js-store.

Installation

npm install react-immutable-js-store

Api

connect({ actions, component, store, subscriptions })

Connects a React component to an immutable-js-store store. This function accepts the following named parameters:

The subscriptions object can contain 2 types of values:

• Array values will be auto-subscribed and the corresponding property will be updated when the subscription is notified.
• Keys with Function values will be called each time the store changes; a single parameter (the current state) will be passed.

Example

import React, { Component } from 'react'
import ImmutableStore from 'immutable-js-store'
import { connect } from 'react-immutable-js-store'

// Initialize store with default data
const store = new ImmutableStore({
  items: [],
  newItemText: ''
})

// Expose the current state of the store to the "connected" component.
// Keys with Array values will be subscribed and have their props auto-updated.
// Keys with Function values will be called each time the store changes.
const subscriptions = {
  hasNext: (state) => store.hasNext(),
  hasPrevious: (state) => store.hasPrevious(),
  newItemText: ['newItemText'],
  items: ['items']
}

// Expose updates to the store to the "connected" component
const actions = {
  addItem: (text) => {},
  removeItemAt: (index) => {},
  stepBack: () => {
    store.stepBack()
  },
  stepForward: () => {
    store.stepForward()
  },
  toggleAll: () => {},
  toggleItemAt: (index) => {}
}
