🧹 Nitpick comments (4)
Server/db/models/Monitor.js (1)

37-39: Consider validating port ranges
Sweaty palms might lead to random port usage! The port field lacks constraints: typical ports fall within 1–65535. Introducing a min-max validation or a default value could shield the system from unexpected out-of-range inputs.

Client/src/Validation/validation.js (1)

112-112: Port field validation
This is a neat addition to ensure the front end doesn’t choke on invalid ports (like 0 or 999999). If more robust constraints are desired, you could add .min(1).max(65535) to keep it real.

Client/src/Pages/Uptime/CreateUptime/index.jsx (1)

53-57: Port entry in monitorTypeMaps is coherent.

Labelling the URL as "URL to monitor" could be fine, but you may consider clarifying the wording if it's strictly a hostname for the port.

Server/validation/joi.js (1)

206-206: Adding a numeric port gets a fist bump!

Dropping "port: joi.number()" is sweet for those back-end checks. Just ensure it never goes negative or out of standard port range, though the code seems fine.

Use a min/max check if you want bulletproof port validation. Something like:

-port: joi.number(),
+port: joi.number().min(1).max(65535),

🔇 Additional comments (20)
Server/db/models/Monitor.js (1)

31-31: Ensure consistency of monitor types
This is the perfect spot to slip in the new “port” type to help with that TCP port check. Just double-check that all relevant parts of the system line up with this addition to avoid any mismatches on usage.

Server/utils/messages.js (2)

62-64: New error message: “PORT_FAIL”
The new message “Failed to connect to port” is clear and concise. Looks good—just ensure that it’s consistently wired up wherever you handle port connectivity failures.


136-137: New success message: “PORT_SUCCESS”
This gleaming success message “Port connected successfully” hits the sweet spot. Keep it consistent with your overall i18n or localization approach if you add more languages in the future.

Server/service/statusService.js (1)

146-146: Seamless integration for port checks
Port checks are now hooking in, so it’s time to drop that spaghetti. Confirm that all related database operations and navigation are aligned, especially for any analytics or metrics that rely on check data.

Server/index.js (2)

47-47: Imported net module successfully.

Great addition. Leveraging the built-in 'net' module is appropriate for TCP or port-related work.


133-133: NetworkService constructor update looks good.

Including 'net' as an argument cleanly extends the service for port monitoring. No issues noted.

Client/src/Pages/Uptime/Home/UptimeTable/index.jsx (1)

77-77: Port type included successfully.

The expanded type array ensures that port monitors are fetched. Confirm server-side availability for these types.

Client/src/Pages/Uptime/CreateUptime/index.jsx (4)

90-90: Conditional port assignment is valid.

Including the port property only when type is 'port' is well-structured.


261-271: New TextInput for port is clear.

Using the hidden prop is straightforward. The static analysis note on boolean usage is optional; your implementation is fine as is.

277-277: Placeholder usage is concise.

Falling back to an empty string is appropriate if a namePlaceholder is not provided.


342-350: Port monitor radio option aligns with other checks.

Consistent UI design for selecting a port monitor. Looks good.

Client/src/Features/UptimeMonitors/uptimeMonitorsSlice.js (1)

89-89: Adds 'port' to the types array properly.

Nicely matches the usage across the client for port monitoring.

Server/validation/joi.js (2)

147-152: Yo, new type is shining bright!

They added "port" in the roll call of valid monitor types, making the schema more versatile. Everything seems solid like a rock, no shady lines or second thoughts.


168-173: Another port cameo in the type array!

Repeating the groove: "port" is lined up with "http", "ping", "pagespeed", "docker", "hardware". That extra choice is dope; no red flags jump out.

Server/service/networkService.js (4)

11-11: Double-check your doc block flow, bro!

The param doc for net is on point. Ain’t no flaws in that doc hustle.


15-15: Constructor’s got net in the mix—fresh beats!

You introduced net with style, now all network-based tunes can bounce. Looks like a clean pass, no meltdown in logic.

Also applies to: 21-21, 30-30


271-323: The port-check jam is live!

Droppin’ lines for requestPort method, establishing connections like it’s breakbeats. The error handling, timeouts, and destroy calls rock steady. Just watch out for memory leaks if sockets ain’t closed on error—but you’ve handled that. Great job!


360-361: Switchin’ to the port flow—no more neglected type!

Routing "port" jobs to requestPort is consistent with the rest. Everything’s neat, so the method can vibe right along with HTTP, Docker, and Ping.

Server/db/mongo/modules/monitorModule.js (2)

24-24: ‘port: Check,’ is the new verse!

Now the CHECK_MODEL_LOOKUP spits out checks for port monitors without missing a beat. All good in these lines.


355-360: Group hug for port stats!

This “if” block adding "port" keeps the synergy with "http", "ping", and "docker". Now average response time and uptime stats can include that port vibe, too.

    • Analysis:
      • Current logic and potential issues: The current logic adds "port" to the list of types for fetching monitors. This change is straightforward but has implications for the backend service that handles this request. If the backend is not prepared to handle the new "port" type, it could lead to errors or incorrect data being returned.
      • Edge cases and error handling: The backend service must be able to handle the new "port" type gracefully. If the backend does not support this type, it should return an appropriate error message.
      • Cross-component impact: This change affects the data retrieval logic, which in turn impacts the UI components that display this data. If the backend returns incorrect data or errors, it could lead to UI issues.
      • Business logic considerations: The addition of the "port" type should be aligned with business requirements. If the business logic for handling "port" type monitors is not fully defined, it could lead to inconsistencies.
    • LlamaPReview Suggested Improvements:
      export const getUptimeMonitorsByTeamId = createAsyncThunk(
      	"monitors/getMonitorsByTeamId",
      	async (token, thunkApi) => {
      		const user = jwtDecode(token);
      		try {
      			const res = await networkService.getMonitorsAndSummaryByTeamId({
      				authToken: token,
      				teamId: user.teamId,
      				types: ["http", "ping", "docker", "port"],
      			});
      			if (res.data && res.data.error) {
      				throw new Error(res.data.error);
      			}
      			return res.data;
      		} catch (error) {
      			if (error.response && error.response.data) {
      				return thunkApi.rejectWithValue(error.response.data);

      			};
      			return thunkApi.rejectWithValue(payload);
      		}
      	}
      );
    • Improvement rationale:
      • Technical benefits: Adding error handling for the case where the backend returns an error in the response data ensures that the frontend can gracefully handle such scenarios. This prevents potential UI issues and provides better feedback to the user.
      • Business value: Ensuring that the frontend can handle errors from the backend aligns with the business requirement of providing a robust and reliable user experience.
      • Risk assessment: The risk of UI issues due to backend errors is mitigated by adding this error handling. However, there is a slight risk of increased complexity in the code, which can be managed through proper testing.

    • Analysis:
      • Current logic and potential issues: The current logic creates a TCP connection to the specified URL and port. However, it does not handle the case where the URL is invalid or the port is not open. This could lead to false positives or negatives in monitoring results.
      • Edge cases and error handling: The error handling should be robust enough to handle various network errors, such as invalid URLs, closed ports, or network timeouts. Appropriate error messages should be logged and returned to the caller.
      • Cross-component impact: This change affects the network service, which in turn impacts the monitoring results and the UI components that display these results. If the network service returns incorrect data or errors, it could lead to UI issues.

We could extract these to a variable, maybe an array, and destructure them here. That way we can update in one place and use it in four, do you like the idea?

Absolutely, it was a pain tracking these down all over the app 😂.

Good idea, how about I open a separate PR for that one?
