react-rflux v0.13.8
rflux
ReactJS Flux/Redux reimagined using Functional Reactive Programming with KefirJS + epics.
Installation
With npm:
npm install --save react-rfluxor with jspm:
jspm install npm:react-rfluxWhy rflux?
- Lightweight at less than 30k. With KefirJS, it's still less than 40k!
 - Code components in a manner similar to redux. The power of functional reactive programming as needed. Epics baked right in.
 - Redux compatible. Use redux reducers and middleware. 
redux-dev-toolscompatibility is in the works! 
Why Epics?
Epics can be thought of as observable-based sagas. (If you don't know what sagas are, think of these as a way to handle async workflows.) The main advantage to epics is that observables are standards based. Both describe a language on top of Javascript. However, I strongly suspect that functional reactive programming with observables is more powerful than sagas.
Oh and by the way, functional reactive programming (or FRP) is just programming with 
asynchronous data streams. Think map/reduce but with an asynchronous data source 
instead of arrays. 
Usage Example
Build a channel.
// counter.actiontypes.js
export default {
  increment: 'increment',
  decrement: 'decrement',
}
// counter.actions.js
export default {
  increment: x => ({channel: 'counter', actionType: 'increment', payload: x}),
  decrement: x => ({channel: 'counter', actionType: 'decrement', payload: x})
}
// counter.reducers.js
export default {
  initialState: 0,
  increment(state, action) {
     const {payload} = action
     return state + payload
  },
  decrement(state, action) {
    const {payload} = action
    return state - payload
  }
}
// counter.channel.js
import ActionTypes from './counter.actiontypes'
import Reducers from './counter.reducers'
import ActionFunctions from './counter.actions'
export default {
  channel: 'counter',
  ActionTypes,
  Reducers,
  ActionFunctions
}Build the app state
// appstate.js
import appStateFactory from 'react-rflux'
const {AppState} = appStateFactory({
  channels: [CounterChannel]
})Hook up the component
import {Container} from 'react-rflux'
import {AppState} from './appstate'
const Counter = ({value, inc, dec}) => 
  <div>
     <div>Value: {value}</div>
     <button onClick={inc}>increase</button>
     <button onClick={dec}>decrease</button>
  </div>
const CounterContainer = () => {
  return (
    <Container
       value={AppState.observables.counter}
       inc={() => AppState.actions.increment(1)}
       dec={() => AppState.actions.decrement(2)}
    >
      <Counter/>
    </Container>
  )
