Utilities for managing mouse state with redux.

Setup

First, add the reducer somewhere in your reducer tree. It's just a reducer so you can put it wherever you want! For example, you could put it in your top level call to combineReducers.

// reducer.js

import {combineReducers} from 'redux'
import {mouseReducer} from 'redux-mouse'

export default combineReducers({
    mouse: mouseReducer,
})

Second, you must add the event handlers to the window. To do this, use the provided store enhancer.

// store.js

import {createStore} from 'redux'
import {mouseStoreEnhancer} from 'redux-mouse'
import reducer from './reducer'

const store = createStore(reducer, mouseStoreEnhancer)

// or, if you have an initial state for the store
const store = createStore(reducer, initialState, mouseStoreEnhancer)

export default store

Note that if you are also using some middlewares, the call will look more like this:

import {createSore, applyMiddlewares, compose} from 'redux'
import {mouseStoreEnhancer} from 'redux-mouse'
import reducer from './reducer'

const store = createStore(
    reducer,
    compose(
        mouseStoreEnhancer,
        applyMiddlewares(middleware1, middleware2)
    )
)

// or, if you have an initial state for the store
const store = createStore(
    reducer,
    initialState,
    compose(
        mouseStoreEnhancer,
        applyMiddlewares(middleware1, middleware2)
    )
)

export default store

The Mouse State

The mouseReducer adds an object with the following keys to the store:

• isDown: (bool) True if the mouse is down. False if it is up.
• x: (number) The x position of the mouse.
• y: (number) The y position of the mouse.

For example, if you put the mouseReducer under the key mouse (as is done in the examples above) then you can access the mouse's coordinates and click state like so

// get the current state from the store
const state = store.getState()

// mouse's x position
state.mouse.x
// mouse's y position
state.mouse.y
// true if the mouse is down.  false if it is up.
state.mouse.isDown
