Why Redux reducer returns undefined after action click?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have a React-table in which I pass data from reducer's initialState like this:
const getData = () => {
return {
data: [{},{},{}]
}
}
const initialState = getData();
const ipReducer = (state = initialState, action) => {
if (action.type === 'CHANGE_IP_STATUS') {
let newState = Object.assign({}, state);
return { newState }
} else {
return state;
}
}
export default ipReducer;
getData() will get data from server.
And I have switchers in table rows which can change the table data state. So I perform a redux action to change the state of a table. But when the action is done the table table gets undefined data.
This is my table:
<div>
<ReactTable
data={this.props.data}
columns={columns}
/>
</div>
And this is my state to props map:
const mapStateToProps = (state) => ({
data: state.ipTable.data,
})
From console.log() I see that my ipReducer returns valid data object. But why this object doesn't appears in my table component after change state perform?

Instead of returning return { newState } you should just return newState since its already an object created from updated state
const ipReducer = (state = initialState, action) => {
if (action.type === 'CHANGE_IP_STATUS') {
let newState = Object.assign({}, state);
return newState;
} else {
return state;
}
}
