react-redux-hooks

The easiest way to connect redux. Power by react hooks.

Getting Started

Install

npm install react-redux-hooks

or

yarn add react-redux-hooks

Usage

See full examples

Connect to redux in component

Just use useRedux. It would return state and dispatch

import { useRedux } from 'react-redux-hooks';

const ToggleButton = () => {
	const [state, dispatch] = useRedux();

	return (
		<button onClick={() => dispatch({ type: 'TOGGLE' })}>
			{state.toggle ? 'Click to close' : 'Click to open'}
		</button>
	);
};

Top level Provider

Just pass redux store with Provider like react-redux.

import React from 'react';
import { createStore } from 'redux';
import { Provider, useRedux } from 'react-redux-hooks';

const store = createStore((state = { toggle: false }, action) => {
	if (action.type === 'TOGGLE') {
		return { toggle: !state.toggle };
	}

	return state;
});

ReactDOM.render(
	<Provider store={store}>
		<ToggleButton />
	</Provider>,
	document.getElementById('content'),
);

Advanced usage

Just like react-redux. We combine Selector, and actions creator in react-redux-hooks

Define mapStateToHook

Just like mapStateToProps.

mapStateToHook should be defined as a function:

function mapStateToHook(state)

Arguments

• state is the store.getState() return value

Return

• Must return plain object

Example:

const mapStateToHook = (state) => state.toggle;

const [toggle, dispatch] = useRedux(mapStateToHook);

Define mapDispatchToHook

Just like mapDispatchToProps.

mapDispatchToHook Could defined as the three types:

• undefined would return dispatch on hook by default
• function would pass dispatch as the function parameter for user customize
• object would combine redux's bindActionCreators by default

Define mapDispatchToHook as the undefined

Return dispatch on hook by default.

Example:

const [, dispatch] = useRedux();

Define mapDispatchToHook as the function

Pass dispatch as the function parameter for user customize.

Example:

const mapDispatchToHook = (dispatch) =>  dispatch({ type: 'TOGGLE' });

const [, onToggle] = useRedux(undefined, mapDispatchToHook);

Define mapDispatchToHook as the object

Combine redux's bindActionCreators by default

Example:

const onToggleAction = () => ({ type: 'TOGGLE' });

const mapDispatchToHook = { onToggle: onToggleAction };

const [, onToggle] = useRedux(undefined, mapDispatchToHook);
