# RequestsHandler

RequestsHandler can handle your requests. You can abort last requests before ended or resolve them. You can do that using methods from RequestsHandler class instance or by emit events from components. This is example how handle request:

{% tabs %}
{% tab title="Javascript" %}

```javascript
import { RequestsHandler, EventsReceiver, Eventrix } from 'eventrix';
import axios from 'axios';

const eventrix = new Eventrix();
const requestsHandler = new RequestsHandler(eventrix);

const fetchUsersReceiver = new EventsReceiver(
    'Users:fetchList',
    (eventName, eventData, stateManager) => {
        const requestId = 'fetchUsers';
        return requestsHandler.handleRequest(
            axios.get('https://abc.com/users'),
            requestId
        ).then(({ data }) => {
            stateManager.setState('users', data);
        });
    }
);

eventrix.useReceiver(fetchUsersReceiver)

export default eventrix;
```

{% endtab %}

{% tab title="Second Tab" %}

{% endtab %}
{% endtabs %}

When you handle request in this way you can abort them by emit event 

```
emit('AbortRequest:fetchUsers', rejectData)
```

You can also abort last requests using RequestsHandler instance

```javascript
import { RequestsHandler, EventsReceiver, Eventrix } from 'eventrix';
import axios from 'axios';

const eventrix = new Eventrix();
const requestsHandler = new RequestsHandler(eventrix);

const fetchUsersReceiver = new EventsReceiver(
    'Users:fetchList',
    (eventName, eventData, stateManager) => {
        const requestId = 'fetchUsers';
        requestsHandler.abortAllById(requestId, 'request rejected'); // reject last requests
        return requestsHandler.handleRequest(
            axios.get('https://abc.com/users'),
            requestId
        ).then(({ data }) => {
            stateManager.setState('users', data);
        });
    }
);

eventrix.useReceiver(fetchUsersReceiver)

export default eventrix;
```

### **Abort event structure**

 **"**AbortRequest:" + **request\_id**

### Resolve event structure

"ResolveRequest:" + **request\_id**

### RequestsHandler instance methods

**abortAll**(rejectData: any) - abort all pending requests

**abortAllById**(requestId: string, responseData: any) - abort all pending requests with requestId

**resolveAll**(rejectData: any) - resolve all pending requests

**resolveAllById**(requestId: string, responseData: any) - resolve all pending requests with requestId

**isAnyPending**(): boolean - check if any request pending

**isPending**(requestId: string): boolean - check if any request pending with requestId
