Alert Integration & Data Validation src/composables/useSerialTerminal.js |
Added ref import and useAlert composable integration; initialized sendAlert within useSerialPorts; tightened response handling to validate response.data.data is an array, resetting serialPortList to [] if invalid; augmented error handling with alert dispatch for non-success responses and catch blocks. |

- Single file modified with consistent pattern changes across multiple functions
- Validation logic is straightforward array type checking
- No changes to method signatures or public API surface
Poem
🐰 Alert, alert! The ports are validated bright,
No more silent failures in the night!
With array checks and messages clear,
Every error whispers true and fair.
A rabbit's refactor, neat and tight! 🎉

33-35: Fix error message wording.The phrase "Catch to get serial port list" is awkward for user-facing error messages.
Apply this diff to improve clarity:
- const message = error.message || 'Catch to get serial port list'; + const message = error.message || 'Failed to get serial port list';
58-60: Fix error message wording.The phrase "Catch to set serial port" is awkward for user-facing error messages.
Apply this diff to improve clarity:
- const message = error.message || 'Catch to set serial port'; + const message = error.message || 'Failed to set serial port';

47-51: Consider alerting on malformed data and simplify validation.Same issues as in
getPortList(lines 22-26): the validation silently fails on malformed data and includes a redundant truthiness check.Apply this diff:
- if (response.data.data && Array.isArray(response.data.data)) { + if (Array.isArray(response.data.data)) { serialPortList.value = response.data.data; } else { serialPortList.value = []; + sendAlert('warning', 'Serial', 'Received unexpected data format from server'); }

src/composables/useSerialTerminal.js (2)
22-26: Consider alerting on malformed data and simplify validation.The validation correctly falls back to an empty array when data is not an array, but this silent failure could hide API or server-side issues. Consider sending an alert when
response.data.code === 0but the data shape is unexpected.Additionally, the
response.data.data &&check is redundant sinceArray.isArray()already returnsfalsefornullandundefined.Apply this diff to simplify validation and add alerting:
- if (response.data.data && Array.isArray(response.data.data)) { + if (Array.isArray(response.data.data)) { serialPortList.value = response.data.data; } else { serialPortList.value = []; + sendAlert('warning', 'Serial', 'Received unexpected data format from server'); }
18-62: Consider extracting common validation logic.Both
getPortListandsetSerialshare identical validation and error handling patterns. Extracting this into a helper function would improve maintainability and ensure consistency.Consider adding a helper function like this at the module level:
const handleSerialResponse = (response, sendAlert, actionDescription) => { if (response.status === 200 && response.data.code === 0) { if (Array.isArray(response.data.data)) { return response.data.data; } else { sendAlert('warning', 'Serial', 'Received unexpected data format from server'); return []; } } else { const message = response.data.msg || `Failed to ${actionDescription}`; sendAlert('error', 'Serial', message); return []; } };Then simplify both functions:
const getPortList = async () => { try { const response = await http.get('/serial'); serialPortList.value = handleSerialResponse(response, sendAlert, 'get serial port list'); } catch (error) { const message = error.message || 'Failed to get serial port list'; sendAlert('error', 'Serial', message); serialPortList.value = []; } };

3-3: LGTM! Essential imports added.The
refimport fixes a missing dependency for the reactive references used at lines 12-13, and theuseAlertimport provides the error notification functionality used throughout the file.Also applies to: 7-7
16-16: LGTM! Proper alert initialization.The
sendAlertfunction is correctly initialized and scoped within the composable function.
