redux ========================= An experiment in fully hot-reloadable Flux. **The API might change any day.** _**Don't use in production.**_ ## Why another Flux framework? Read **[The Evolution of Flux Frameworks](https://medium.com/@dan_abramov/the-evolution-of-flux-frameworks-6c16ad26bb31)** for some context. ### Design Goals * Hot reloading of everything. * A hook for the future devtools to "commit" a state, and replay actions on top of it during hot reload. * No `createAction`, `createStores`, `wrapThisStuff`. Your stuff is your stuff. * I don't mind action constants. Seriously. * Keep Flux lingo. No cursors or observables in core. * Have I mentioned hot reloading yet? ## Demo ``` git clone https://github.com/gaearon/redux.git redux cd redux npm install npm start ``` ## What's it look like? ### Actions ```js // Still using constants... import { INCREMENT_COUNTER, DECREMENT_COUNTER } from '../constants/ActionTypes'; // But action creators are pure functions returning actions export function increment() { return { type: INCREMENT_COUNTER }; } export function decrement() { return { type: DECREMENT_COUNTER }; } // Can also be async if you return a function // (wow, much functions, so injectable :doge:) export function incrementAsync() { return dispatch => { setTimeout(() => { dispatch(increment()); }, 1000); }; } // Could also look into state in the callback form export function incrementIfOdd() { return (dispatch, state) => { if (state.counterStore.counter % 2 === 0) { return; } dispatch(increment()); }; } ``` ### Stores ```js // ... too, use constants import { INCREMENT_COUNTER, DECREMENT_COUNTER } from '../constants/ActionTypes'; // but you can write this part anyhow you like: const initialState = { counter: 0 }; function increment({ counter }) { return { counter: counter + 1 }; } function decrement({ counter }) { return { counter: counter - 1 }; } // what's important is that Store is a pure function too export default function counterStore(state = initialState, action) { // that returns the new state when an action comes switch (action.type) { case INCREMENT_COUNTER: return increment(state, action); case DECREMENT_COUNTER: return decrement(state, action); default: return state; } } // bonus: no special support needed for ImmutableJS, // just return its objects as the state. ``` ### Components #### Dumb Components ```js // The dumb component receives everything using props: import React, { PropTypes } from 'react'; export default class Counter { static propTypes = { counter: PropTypes.number.isRequired, increment: PropTypes.func.isRequired, decrement: PropTypes.func.isRequired }; render() { const { counter } = this.props; return (

Clicked: {counter} times

); } } ``` #### Smart Components ```js // The smart component may inject actions // and observe stores using : import React, { Component } from 'react'; import { Root, Container } from 'redux'; import { increment, decrement } from './actions/CounterActions'; import counterStore from './stores/counterStore'; import Counter from './Counter'; export default class CounterContainer { render() { // stores can be a single store or an array. // actions can only be a string -> function map. // props passed to children will combine these actions and state. return ( {props => } ); } } ``` #### The root component ```js import React from 'react'; import { Root } from 'redux'; @Root export default class App { /* ... */ } ``` ## FAQ ### How does hot reloading work? * http://webpack.github.io/docs/hot-module-replacement.html * http://gaearon.github.io/react-hot-loader/ * those `module.hot` lines in the dispatcher example above ### Can I use this in production? I wouldn't. Many use cases are not be considered yet. If you find some use cases this lib can't handle yet, please file an issue.
