# Redocer

_Pronounced: reducer_

A custom reducer enhancer that returns a reducer that handles undo and redo

actions.

### API

```jsx

import makeRedocer from 'redocer'

function reducer(state, action) { ... };

let redoable = makeRedocer(reducer, initialState);

// Regular actions pass through to the original reducer

redoable(state, 'some-action')

// if you have already called the reducer with a custom action

// then you can call it with a `redo` action, returning the previous state

redoable(state, 'redo')

// Once you have redone a change, you can call the reducer with `undo`

redoable(state, 'undo')

```
