[FIXED] How to Check if Axios Call Fails due to No Internet Connection?

Issue

I'm trying to figure out an accurate way to detect axios call failure due to no internet connection.

Does axios call failure return a specific response object or specific response status code or throw a specific error details for the no internet connection scenario?

Example of what i will use the "detection of axios failure due to no internet connection" for

try {
    const res = await server.get('/auth/user?', {
            params: {
                refreshToken: refreshToken,            
                userID: userID
            }
        }
    );

    if(res.user.data){
        dispatch({type: LOGIN_USER_SUCCESS, payload: res.data.user});
    } else {
        if(res.axiosFailsDueToNoInternetConnection){
            alert('no internet connection');
            dispatch({type: RELOAD});
        }
    }

} catch (error) {
    if(error.dueToNoInternetConnection){
        alert('no internet connection');
        dispatch({type: RELOAD});
    }
}

Solution

In your catch clause you can check whether the error is caused by network error or not:

catch (error) {
    if(error.toJSON().message === 'Network Error'){
        alert('no internet connection');
        dispatch({type: RELOAD});
    }
}
