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

You can enhance the behavior of the redux-form reducer by calling additional methods on it when you mount it to the Redux state. You may call as many of these on it as you wish, and each will return a new copy of the reducer with the additional functionality.

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

Returns a form reducer that will also run the synchronous validation function given for each form name.

The old v5 functionality of normalize() and plugin() have not yet been implemented in v6.
