reducer

The form reducer. Should be given to mounted to your Redux state at form.

If you absolutely must mount it somewhere other than form, you may provide a getFormState(state) function to the reduxForm() decorator, to get the slice of the Redux state where you have mounted the redux-form reducer.

ES5 Example

var redux = require('redux');
var formReducer = require('redux-form').reducer;

var reducers = {
  // ... your other reducers here ...
  form: formReducer
};
var reducer = redux.combineReducers(reducers);
var store = redux.createStore(reducer);

ES6 Example

import { createStore, combineReducers } from 'redux';
import { reducer as formReducer } from 'redux-form';

const reducers = {
  // ... your other reducers here ...
  form: formReducer
};
const reducer = combineReducers(reducers);
const store = createStore(reducer);

Additional Functionality

reducer.normalize(Object<String, Object<String, Function>>)

Returns a form reducer that will also pass each form value through the normalizing functions provided. The parameter is an object mapping from formName to an object mapping from fieldName to a normalizer function. The normalizer function is given four parameters and expected to return the normalized value of the field. See details.
