[Recompose] Add Local State with Redux-like Reducers using Recompose
Learn how to use the ‘withReducer‘ higher order component using the alternative reducer form. If you like using reducers in redux, you’ll be able to reuse that same technique but for local state.
import React from ‘react‘;import {withReducer, withHandlers, compose} from ‘recompose‘;const UserStyle = { position: ‘relative‘, background: ‘lightblue‘, display: ‘inline-block‘, padding: ‘10px‘, cursor: ‘pointer‘, marginTop: ‘50px‘};const StatusListStyle = { background: ‘#eee‘, padding: ‘5px‘, margin: ‘5px 0‘};const TooltipStyle = { fontSize: ‘10px‘, position: ‘absolute‘, top: ‘-10px‘, width: ‘80px‘, background: ‘#666‘, color: ‘white‘, textAlign: ‘center‘};const StatusList = () => <div style={StatusListStyle}> <div>pending</div> <div>inactive</div> <div>active</div> </div>;const withToggle = compose( withReducer(‘toggleState‘, ‘dispatch‘, (state = false, action) => { switch(action.type) { case ‘SHOW‘: return true; case ‘HIDE‘: return false; case ‘TOGGLE‘: return !state; default: return state; } }, false), withHandlers({ toggle: ({dispatch}) => (e) => dispatch({type: ‘TOGGLE‘}), show: ({dispatch}) => (e) => dispatch({type: ‘SHOW‘}), hide: ({dispatch}) => (e) => dispatch({type: ‘HIDE‘}) }));const Statue = withToggle( ({ status, toggle, toggleState }) => (<span onClick={() => toggle(!toggleState)}> {status} {toggleState && <StatusList/>} </span>));const Tooltip = withToggle(({ show, hide, toggleState, text, children }) => ( <span> <span> {toggleState && <div style={TooltipStyle}> { text } </div>} <span onm ouseOver={show} onm ouseOut={hide} > { children } </span> </span> </span>));const User2 = ({ status, name }) => ( <div style={UserStyle}> <Tooltip text="Cool Dude!">{name}</Tooltip>- <Statue status={status}/> </div>);export default User2;
‘withReducer‘ take (state_name, dispatch_function, reducer_function, init_state) as params.
