The React hook for managing the state of the XState machine is used to connect React components with state machines defined in XState. First, we import the necessary functions and tools:
|`React`| Provides access to core React functions and components, allowing the creation of components and state management in React applications. |
42
-
|`createContext`| Creates a React context, enabling data sharing between components without manually passing props through each level of the component tree. |
43
-
|`useContext`| Allows accessing the value of the React context in a functional component, enabling consuming the context and using its value anywhere within the component. |
44
-
|`useEffect`| Enables executing side effects in React components, such as subscriptions to external data, DOM updates, and resource cleanup. |
45
-
|`useRef`| Creates a mutable reference that persists throughout the component's lifecycle, primarily used for accessing DOM nodes or mutable values without causing additional re-renders. |
46
-
|`useState`| Adds local state to functional components in React, allowing declaring state variables within a functional component and updating them using the `setState` method. |
47
25
|`useActor`| Provides access to XState actors in React components, allowing subscribing to changes in actor state and sending events to state machines. |
48
26
|`Actions`| Provides functions and utilities for defining actions within XState machines, representing operations performed in response to events. |
49
27
|`assign`| Defines an action that assigns values to properties of the state machine's context. |
Overall, these custom hooks encapsulate the logic for accessing state data, obtaining the current state of the state machine, and sending events to the state machine. They provide convenient abstractions for interacting with the state machine within React components, promoting code reusability and maintainability.

The React hook for managing the state of the XState machine provides an efficient and straightforward way to interact with state machines in React applications. By following this guide, developers can easily integrate state machine logic into their React components in an organized and efficient manner.
The `getInternetStatus` function checks if the device has an active internet connection by attempting to reach Google's homepage. It returns a boolean value indicating whether the internet is accessible.

#### Imports
21
+
```javascript
22
+
importaxios, { AxiosRequestConfig } from'axios';
23
+
import { Sid } from'..';
24
+
```
25
+
-**axios**: Used for making HTTP requests.
26
+
-**AxiosRequestConfig**: Type used for configuring the axios request.
27
+
-**Sid**: A type imported from the parent directory, presumably representing session ID or similar credentials.
28
+
29
+
#### Parameters
30
+
-`sid`: A session identifier of type `Sid`, required to authenticate or manage the session context for the request.
31
+
32
+
#### Returns
33
+
-**Promise of boolean**: ```Promise<boolean>``` A promise that resolves to `true` if the internet is reachable, otherwise `false`.
34
+
35
+
#### Function Logic
36
+
1.**Prepare the Request:**
37
+
- The function constructs a JSON string that includes the command to check internet connectivity by using `wget` to quietly fetch Google's homepage.
38
+
- The command will print 'true' if the fetch is successful, and 'false' otherwise.
- The catch block handles various errors such as axios cancellation due to timeout, server responses indicating failure, no response received, or other axios errors.
77
+
- In any error scenario, the function returns `false`, indicating no internet connectivity.
