### Bug Description

The HapRamp alpha web app allows users to browse the app as a guest (i.e. without signing in). This is a good thing for people who just come in to read some content and walk away. But it may be possible that these guest users try to rate/comment on the app.

Previously, there was no check for auth status and hence the actions were not restricted. In this post, I will be describing the way in which I handled this case without having to change a significant part of the code.

### Solution

To achieve this, I created an intermediate wrapper for the actions which would check the login status of current user and dispatch accordingly. It worked using the following logic - 

- Is the user logged in while performing the action?
  - Yes
    Let him perform the action
  - No
    Toast a UI notification asking them to log in.

The function looks something like this - 

```js
import notify from './notification';  // For creating UI notifications
import getStore from './storeUtils';  // For getting store state

const notAuthorizedError = () => dispatch => {
	notify.danger('Please log in first!');
	return Promise.reject();
};

export const authRequired = target => getStore().getState().login.isLoggedIn ? target : notAuthorizedError;
```

All the actions that required auth from user were then wrapped with this function to achieve the desired results. Here is an example - 

```js
export const ratePost = authRequired((author, permlink, vote) => dispatch => {
  ...  // Implementation of actual action
});
```
