# STEP-6 Extension plugins

In this step, we going finally write our first Extension plugins, at first we will assign our reducer to the global redux store, and then will plugin into the Router container mapDispatchToProps.

[**STEP-6**](https://github.com/GAkim/SocialShareGraphQl/tree/STEP-6)

1. First, let’s add our reducer.\
   In your **\<SOURCE>/plugin** create the file **StoreReducer.plugin.js**

{% code title="scandipwa-socialshare/src/plugin/StoreReducer.plugin.js" %}

```javascript
import { SocialShareReducer } from '../store/SocialShare/SocialShare.reducer';

const getStaticReducers = (args, callback, instance) => ({
   ...callback(...args),
   SocialShareReducer
});

export const config = {
   'Store/Index/getStaticReducers': {
       function: getStaticReducers
   }
};

export default config;
```

{% endcode %}

&#x20;   2\. Open [**Redux DevTools**](https://chrome.google.com/webstore/detail/redux-devtools/lmhkpmbekcpmknklioeibfkpmmfibljd) you should see **SocialShareReducer** object initial state.\
&#x20;look into **SocialShare.reducer.js lines 4 - 8**\

3\. What we want to succeed is to load all related to social share configurations on the initial page load.\
The same way that **ConfigReducer** does.\
In **Router Container** we can find ***initializeApplication*** method which is calling initial prop method **init();** here is our source theme **mapDispatchToProps&#x20;*****and initializeApplication***&#x20;

{% tabs %}
{% tab title=" mapDispatchToProps" %}
{% code title="src/component/Router/Router.container.js line 62 - 83" %}

```javascript
/** @namespace Component/Router/Container/mapDispatchToProps */
export const mapDispatchToProps = (dispatch) => ({
   updateMeta: (meta) => dispatch(updateMeta(meta)),
   updateConfigDevice: (device) => dispatch(updateConfigDevice(device)),
   init: () => {
       ConfigDispatcher.then(
           ({ default: dispatcher }) => dispatcher.handleData(dispatch)
       );
       MyAccountDispatcher.then(
           ({ default: dispatcher }) => dispatcher.handleCustomerDataOnInit(dispatch)
       );
       WishlistDispatcher.then(
           ({ default: dispatcher }) => dispatcher.updateInitialWishlistData(dispatch)
       );
       CartDispatcher.then(
           ({ default: dispatcher }) => dispatcher.updateInitialCartData(dispatch)
       );
       ProductCompareDispatcher.then(
           ({ default: dispatcher }) => dispatcher.updateInitialProductCompareData(dispatch)
       );
   }
});
```

{% endcode %}
{% endtab %}

{% tab title="initializeApplication " %}
{% code title="src/component/Router/Router.container.js lines 197 - 200" %}

```javascript
    initializeApplication() {
        const { init } = this.props;
        init();
    }
```

{% endcode %}
{% endtab %}
{% endtabs %}

Of course, we could plugin into **mapDispatchToProps** add new prop, then plugin into **initializeApplication** call original method and then our&#x73;**,** but it would be too boring, that why we going to plugin just in **mapDispatchToProps** and then going to mutate **init** prop method,\
let’s begin, In you **\<SOURCE>/plugin** create the file **RouterContainerMDTP.plugin.js**

{% code title="scandipwa-socialshare/src/plugin/RouterContainerMDTP.plugin.js" %}

```javascript
export const SocialShareDispatcher = import(
   /* webpackMode: "lazy", webpackChunkName: "dispatchers" */
   '../store/SocialShare/SocialShare.dispatcher'
);

/** @namespace ScandipwaSocialshare/Plugin/RouterContainerPlugin/mapDispatchToProps */
export const mapDispatchToProps = (args, callback, instance) => {
   const [dispatch] = args;
   const mdtp = callback(...args);
   const { init } = mdtp;

   mdtp.init = (...args) => {
       init(...args);
       SocialShareDispatcher.then(
           ({ default: dispatcher }) => dispatcher.handleData(dispatch)
       );
   };

   return mdtp;
};

export const config = {
   'Component/Router/Container/mapDispatchToProps': {
       function: mapDispatchToProps
   }
};

export default config;

```

{% endcode %}

4\. Now restart your frontend and open [**Redux DevTools**](https://chrome.google.com/webstore/detail/redux-devtools/lmhkpmbekcpmknklioeibfkpmmfibljd) you should find **SocialShareReducer** object with value coming from the backend from our resolver check\
**ScandiPWA/SocialShareGraphQl/Model/Resolver/SocialShare.php line 27 -32**\

Congrats, the most important part is done, we establish data transfer between our backend and frontend and, created a new reducer.<br>
