ReactJS Flux/Redux reimagined using Functional Reactive Programming with KefirJS + epics.
With npm:
npm install --save react-rflux
or with jspm:
jspm install npm:react-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-tools
compatibility is in the works!
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.
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>
)
}
