I use redux + react to build my website, and I want to use redux to control a sidebar visible.The sidebar is defined by semantic-ui-react.Because I want to control it across another component, so I defined the props in sidebar's parent component const { visible, dispatch } = this.props, there is a onClick function to handle this. I will show my code.
Uncaught Error: Actions must be plain objects. Use custom middleware for async actions.
This error confused me one afternoon, and I don't know why! This is my action code:
**action**
export const SIDEBARISVISIBLE = 'sidebarVisible'
export function sidebarVisibleAction() {
return { type: SIDEBARISVISIBLE }
}
As you can see, I defined an action creator returned a plain object.
And this is my reducer code:
**reducer**
import SIDEBARISVISIBLE from '../actions/outside.js'
function sidebarVisible(state = {
sidebarIsVisible: false
}, action) {
switch (action.type) {
case SIDEBARISVISIBLE:
return Object.assign({}, state, {
sidebarIsVisible: !state.sidebarIsVisible
})
default:
return state
}
}
export default sidebarVisible
Also my store code:
**store**
import { createStore, applyMiddleware, compose } from 'redux'
import thunk from 'redux-thunk'
import sidebarVisible from '../reducers/outside.js'
export default initialState => {
return createStore(
sidebarVisible,
initialState,
applyMiddleware(thunk)
)
}
Then, my component code(part of):
class OutsideView extends Component {
constructor(props) {
super(props)
this.state = { activeItem: '' }
}
handleItemClick = (e, { name }) => this.setState({ activeItem: name })
render() {
const { activeItem } = this.state
const { visible, dispatch } = this.props
return (
<div>
<SidebarNav visible={ visible } />
......
<Menu.Item
name='sidebar'
active={ activeItem === 'sidebar'}
onClick={ (e, {name}) => {
this.setState({ activeItem: name })
dispatch(sidebarVisibleAction)
} }>
<Icon color='red' name='list' />
</Menu.Item>
OutsideView.PropTypes = {
visible: PropTypes.bool.isRequired,
dispatch: PropTypes.func.isRequired
}
function mapStateToProps(state) {
return {
visible: state.sidebarIsVisible,
}
}
export default connect(
mapStateToProps
)(OutsideView)
The last, my Router:
import configureStore from './store/index.js'
const store = configureStore()
export default class Root extends Component {
render() {
return (
<Provider store={ store }>
<Router history={ browserHistory }>
<Route path=/ component={ OutsideRedux }>
<Route path='register' component={ Register } />
<Route path='login' component={ Login } />
<Route path='blog' component={ Blog } />
<Route path='about' component={ About } />
<Route path='home' component={ Home } />
<Route path='ask' component={ Ask } />
<Route path='panel' component={ Panel } />
<Route path='setting' component={ Setting } />
<Route path='user' component={ User } />
</Route>
</Router>
</Provider>
)
}
}
So, I search for answer for this error, most of them say, you have to setup redux-thunk and with ApplyMiddleware to use it, the simplest way.But the action I defined is plain object.If I don't use redux-thunk, I think I will not encounter this error either.So, I'm very confused, how to solve this?
Thanks for all the help
