# Redux & React.js
Install required packages
`npm install --save react-redux redux`

## To start using Redux we have to
* Create store
* Create actions
* Create reducer

### Store
`store.js`
```
import { createStore } from 'redux';
import reducers from './reducers';

export const store = createStore(reducers);
```

### Actions
Actions represent changes of the state. We can change state of the store ony by using actions.
Create `index.js` inside `actions` folder.
```
export const fetchUserData = () => ({
  type: 'FETCH_USER_DATA`
});
```

### Provider
We provide top level component with redux store in
`index.js`
```
import { store } from './store';
import { Provider } from 'react-redux';

ReactDOM.remder(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root)
);
```
