Custom implementation of react hook `useReducer` that will cancel all dispatched actions if the component is unmounted and allows to dispatch [thunk actions](https://github.com/reduxjs/redux-thunk) (that will be canceled either).

![demo-gif](/demo.gif)

Open on [codesanbox](https://codesandbox.io/s/use-cancelable-thunk-reducer-lirs9).

## Installation

```

yarn add use-cancelable-thunk-reducer

npm i use-cancelable-thunk-reducer

```

## useCancelableThunkReducer

```javascript

import useCancelableThunkReducer from 'use-cancelable-thunk-reducer';

const [state, dispatch] = useCancelableThunkReducer(

  reducer,

  initialState,

  callback,

  init

);

```

### `reducer`

useReducer first argument.

### `initialState`

useReducer second argument.

### `callback`

default is `undefined`, if is a `function`, when some action is canceled it is called with the action argument: `callback(action)`.

### `init`

useReducer last argument.

## Thunk action

The thunk actions receive `(dispatch, getState)` args.

```javascript

const thunkAction = args => async (dispatch, getState) => {

  dispatch({type: ACTION_SENT});

  const state = getState();

  ...

}

```
