Simple `createReducer` in functional style for Ramda library.

## Installation

```bash

  npm install redux-ramda-reducer

```

## Reducer with redux library

```javascript

  export default (state = 0, action) => {

    switch (action.type) {

      case 'INCREMENT':

        return state + 1

      case 'DECREMENT':

        return state - 1

      default:

        return state

    }

  }

```

## Reducer with redux-ramda-reducer

Without STATE in handler arguments 

```javascript

import * as R from 'ramda';

import { createReducer } from 'redux-ramda-reducer';

import { COUNTER_ACTIONS } from './constants';

const INITIAL_STATE = {

  value: 1,

};

const incrementHandler = () => R.evolve({ value: R.inc });

const decrementHandler = () => R.evolve({ value: R.dec });

const setValueHandler = ({ value }) => R.assoc('value', value);

const HANDLERS = {

  [COUNTER_ACTIONS.SET_VALUE]: setValueHandler,

  [COUNTER_ACTIONS.INCREMENT]: incrementHandler,

  [COUNTER_ACTIONS.DECREMENT]: decrementHandler,

}

export default createReducer(INITIAL_STATE, HANDLERS);

```

If you need STATE in handler:

```javascript

...

const setSameValueHandler = () => (state) => R.assoc('value', state.value)(state);

const HANDLERS = {

  [COUNTER_ACTIONS.SET_SAME_VALUE]: setSameValueHandler,

}

export default createReducer(INITIAL_STATE, HANDLERS);

```
