Motivation
The goal of this library is to provide a simple API to connect your React components to the Redux store. It achieves this by using a single hook useRedux
that subscribes to the state updates in redux store without any need for the traditional Provider
or connect
components.
Installation
yarn add @daniakash/useredux
#or
npm i @daniakash/useredux
Usage
Redux store of a simple counter ﹣
import { createStore } from 'redux'
const countReducer = (
prevState = 0,
action: { type: 'increment' | 'decrement' }
): number => {
switch (action.type) {
case 'increment':
return prevState + 1
case 'decrement':
return prevState - 1
default:
return prevState
}
}
const countStore = createStore(countReducer)
export default countStore
Connecting the countStore to React using useRedux
﹣
import React, { Component } from 'react'
import countStore from './countStore'
import useRedux from '@daniakash/useredux'
const Count = () => {
const count = useRedux(countStore)
return <h1>{count}</h1>
}
const Controller = () => {
const decrement = () =>
countStore.dispatch({
type: 'decrement'
})
const increment = () =>
countStore.dispatch({
type: 'increment'
})
return (
<div>
<button onClick={decrement}>➖</button>
<button onClick={increment}>➕</button>
</div>
)
}
export default function App() {
return (
<div className='App'>
<Count />
<Controller />
</div>
)
}
Working with multiple reducers
If your store has multiple reducers, you can subscribe to the individual reducers by passing the key of the reducer as the second argument to useRedux
If your reducer is ﹣
const rootReducer = combineReducers({
todos: todosReducer,
visibilityFilter: visibilityFilterReducer
})
const store: Store<ApplicationState> = createStore(rootReducer)
To make your component subscribe to updates only on the todosReducer ﹣
const todos = useRedux(store, 'todos')
