How to use combineReducers with handleActions


I'm trying to create new reducer survey, which must combine name and questions reducers while using handleActions from redux-actions package. But I recieve an error Invariant Violation: Expected handlers to be a plain object. How should I change it to actually work?

import { Map, List } from 'immutable';
import { combineReducers } from 'redux-immutable';
import { handleActions } from 'redux-actions';

const initialNameState = List();
const initialQuestionsState = List();

const name = handleActions({}, initialNameState);
const questions = handleActions({}, initialQuestionsState);

export const initialSurveyState = Map({
  name: initialNameState,
  questions: initialQuestionsState
});

export const survey = handleActions(
  combineReducers({
    name,
    questions
  }),
  initialSurveyState
);


Solution

  • handleAction actually creates a reducer. Directly using combineReducer should solve the problem.

    import React, { Component } from 'react';
    import { render } from 'react-dom';
    import { createStore, combineReducers } from 'redux';
    import { connect, Provider } from 'react-redux';
    import { Map, List } from 'immutable';
    import { combineReducers } from 'redux-immutable';
    import { handleActions, createAction, combineActions } from 'redux-actions';
    
    const initialNameState = List();
    const initialQuestionsState = List();
    
    const name = handleActions({}, initialNameState);
    const questions = handleActions({}, initialQuestionsState);
    
    export const survey = combineReducers({name, questions});
    
    const store = createStore(survey);
