14-17: Don't let 'this.user' and 'this.isAdmin' miss their chance to updateJust like seizing the moment, ensure
this.userandthis.isAdminare updated within the store subscription to keep the user's status current. This will prevent any stale user information from lingering in your service.
50-62: Don't let unknown errors make your knees weakIf
error.responseis undefined, possibly due to network issues or unexpected errors, consider handling these cases. Adding anelseclause to manage such scenarios will make your error handling more robust.

Auto Pull Request Review from LlamaPReview
1. Overview
1.1 PR Summary
- Business value and requirements alignment: The PR introduces toast notifications to alert the admin about server issues and proper functioning, improving server monitoring and response time.
- Key components modified:
Client/src/Utils/NetworkService.js - Impact assessment: The PR impacts the user interface (UI) and the network service layer, which handles API requests and responses. It introduces a debounce mechanism to prevent excessive toast notifications and handles errors differently based on the admin's role.
- System dependencies and integration impacts: The PR interacts with
react-toastify,axios,authSlice, anduptimeMonitorsSlice. It also depends on the admin's role and permissions for displaying notifications.
1.2 Architecture Changes
- System design modifications: None
- Component interactions: The PR introduces new interactions between the network service layer and the toast notification component. It also modifies the error handling logic in the network service layer.
- Integration points: The PR integrates with the existing UI, network service layer, and authentication/authorization mechanisms.
2. Detailed Technical Analysis
2.1 Code Logic Deep-Dive
Core Logic Changes
-
Client/src/Utils/NetworkService.js -
handleErrorfunction- Submitted PR Code:
handleError(error) { if (error.response) { const status = error.response.status; if (status === 401) { this.dispatch(clearAuthState()); this.dispatch(clearUptimeMonitorState()); this.navigate("/login"); } else if (this.isAdmin && status >= 500) { this.debounceToast("Checkmate server is not running or has issues. Please check.", "error"); this.errorOccurred = true; } } }
- Analysis:
- The current logic handles 401 errors and 500 errors for admin users. However, it does not handle other error status codes or network errors. It also does not consider the case where the admin is not logged in or does not have the required permissions.
- Edge cases and error handling: The current implementation does not handle other error status codes or network errors. It also does not consider the case where the admin is not logged in or does not have the required permissions.
- Cross-component impact: Changes in error handling might affect other components that rely on the network service layer for error handling.
- Business logic considerations: The current logic assumes that a 500 status indicates a server issue. However, it might not cover all server issues or might be triggered by client-side errors.
- LlamaPReview Suggested Improvements:
handleError(error) { if (error.response) { const status = error.response.status; if (status === 401) { this.dispatch(clearAuthState()); this.dispatch(clearUptimeMonitorState()); this.navigate("/login"); } else if (this.isAdmin && (status >= 500 || status === 0)) { // Include status code 0 for network errors this.debounceToast("Checkmate server is not running or has issues. Please check.", "error"); this.errorOccurred = true; } } else if (error.request) { // Handle network errors this.debounceToast("Checkmate server is not responding. Please check your network connection.", "error"); } else { console.error("An error occurred:", error.message); } }
- Improvement rationale:
- Technical benefits: The improved logic handles network errors and other error status codes, providing more comprehensive error handling.
- Business value: More comprehensive error handling ensures that the admin is notified of a wider range of server issues, enabling quicker resolution.
- Risk assessment: The improved logic reduces the risk of missed server issues and improves the overall system's reliability.
- Submitted PR Code:
-
Client/src/Utils/NetworkService.js -
debounceToastfunction- Submitted PR Code:
debounceToast(message, type, debounceDuration = 5000) { const now = Date.now(); if (now - this.lastToastTimestamp > debounceDuration) { this.lastToastTimestamp = now; type === "success" ? toast.success(message) : toast.error(message); } }
- Analysis:
- The current debounce logic prevents excessive toast notifications by only displaying a new notification if a certain duration has passed since the last notification. However, it does not consider the case where the admin closes the notification before the debounce duration has passed.
- Edge cases and error handling: The current implementation does not handle the case where the admin closes the notification before the debounce duration has passed, potentially leading to excessive notifications.
- Cross-component impact: Changes in the debounce logic might affect other components that rely on toast notifications for displaying messages.
- Business logic considerations: The current logic assumes that the debounce duration is sufficient for the admin to read and act upon the notification. However, it might not be optimal for all use cases.
- LlamaPReview Suggested Improvements:
debounceToast(message, type, debounceDuration = 5000) { const now = Date.now(); if (now - this.lastToastTimestamp > debounceDuration) { this.lastToastTimestamp = now; const toastId = toast[type](message, { autoClose: debounceDuration, onClose: () => { this.lastToastTimestamp = 0; // Reset the timestamp when the toast is closed }, }); } }
- Improvement rationale:
- Technical benefits: The improved logic resets the debounce timestamp when the admin closes the notification, preventing excessive notifications even if the admin closes the notification before the debounce duration has passed.
- Business value: More robust debounce logic ensures that the admin is not overwhelmed with excessive notifications, improving the overall user experience.
- Risk assessment: The improved logic reduces the risk of notification spam and improves the overall system's usability.
- Submitted PR Code:
2.2 Implementation Quality
- Code organization and structure: The PR maintains a clear and organized structure, with the new functions (
handleErroranddebounceToast) added to theNetworkServiceclass. - Design patterns usage: The PR uses the observer pattern for subscribing to store changes and the debounce pattern for preventing excessive toast notifications.
- Error handling approach: The PR introduces more comprehensive error handling, covering a wider range of error status codes and network errors.
- Resource management: The PR does not introduce any new resources that need to be managed.

// Arrange
const networkService = new NetworkService(store, dispatch, navigate);
const error = { response: { status: 401 } };
// Act
networkService.handleError(error);
// Assert
expect(dispatch).toHaveBeenCalledWith(clearAuthState());
expect(dispatch).toHaveBeenCalledWith(clearUptimeMonitorState());
expect(navigate).toHaveBeenCalledWith("/login");
});
test('handleError should handle 500 errors for admin users correctly', () => {
// Arrange
const networkService = new NetworkService({ getState: () => ({ auth: { user: { role: ['admin'] } } }) }, dispatch, navigate);
const error = { response: { status: 500 } };
// Act
networkService.handleError(error);
// Assert
expect(networkService.debounceToast).toHaveBeenCalledWith("Checkmate server is not running or has issues. Please check.", "error");
expect(networkService.errorOccurred).toBe(true);
});
// Test debounceToast function
test('debounceToast should prevent excessive notifications', () => {
// Arrange
const networkService = new NetworkService(store, dispatch, navigate);
const debounceDuration = 5000;
const now = Date.now();
networkService.lastToastTimestamp = now - debounceDuration - 1; // Set lastToastTimestamp to just before the debounce duration
// Act
networkService.debounceToast("Test message", "success");
// Assert
expect(networkService.lastToastTimestamp).toBe(now); // lastToastTimestamp should be updated to the current timestamp
expect(toast.success).toHaveBeenCalledWith("Test message", { autoClose: debounceDuration, onClose: expect.any(Function) });

Out of curiosity are those the toast messages same as the ones in components folder? |
|
I see the configuration of toast in file(https://github.com/bluewave-labs/checkmate/blob/develop/Client/src/Utils/toastUtils.jsx) which is commonly used under components. Presently, I haven't used exactly those same toast but if you want me I can update the code with using those particular toast. |
Yes. If there is a same functionality under components, there is no need to reinvent the wheel. |
|
Thanks for the submission @jasneetsingh6114, I'll have a look at it as soon as I can! |
|
@jasneetsingh6114 I had a brief look and I think you can safely remove all the admin checks and just display the toast for all users. All users should be aware the server isn't responding |

@jasneetsingh6114 as mentioned earlier the admin check is not necessary for this functionality, it can be removed.
The logic for checking if the server is responding or not is not quite correct either.
All that needs to be done in this PR is the following:
if (error.response) {
// current response error implementation
} else if (error.request) {
// Show a toast informing the user the server didn't respond
}
That's all that is needed here, this should be like a 5 line PR.
Simple is often best :smile: | this.lastToastTimestamp = 0; | ||
| this.errorOccurred = false; | ||
| this.user = this.store.getState().auth?.user; | ||
| this.isAdmin = (this.user?.role?.includes("admin") ?? false) || (this.user?.role?.includes("superadmin") ?? false); |

No need to do admin checks, the network error toast shoudl be shown to all users
| class NetworkService { | ||
| constructor(store, dispatch, navigate) { | ||
| this.store = store; | ||
| this.dispatch = dispatch; | ||
| this.navigate = navigate; | ||
| let baseURL = BASE_URL; | ||
| this.lastToastTimestamp = 0; | ||
| this.errorOccurred = false; |

We don't need to worry about informing the user if the server goes back up, if it's up they will know
| if (now - this.lastToastTimestamp > debounceDuration) { | ||
| this.lastToastTimestamp = now; | ||
| type === "success" ? toast.success(message) : toast.error(message); | ||
| } |

Why do you need to debounce the toast? This doesn't seem necessary?
| (response) => { | ||
| if (this.isAdmin && this.errorOccurred && response.status >= 200 && response.status < 300) { | ||
| this.debounceToast("Checkmate server is running properly.", "success"); | ||
| this.errorOccurred = false;// Reset error flag if a successful response is received after errors | ||
| } |

I appreciate the idea here, but I believe it is unnecessary complexity. If the server responds then the user is arleady aware it is functioning properly. This can be removed
| this.navigate("/login"); | ||
| } else if (this.isAdmin && status >= 500) { | ||
| this.debounceToast("Checkmate server is not running or has issues. Please check.", "error"); | ||
| this.errorOccurred = true; |

This won't work if the server doesn't respond at all, which is the issue at hand.
If there is no response, erorr.response will be undefined and the user will not be notfied.
We should be checking for error.request, which is the property that will be defined in the event of a request error.
