52-78: Fix multiple header writes and inconsistent error handlingThere are several issues in the response handling flow:
WriteHeaderis called twice (lines 52 and 71), but only the first call has any effect- In the error case,
http.Erroris called afterWriteHeader, which is incorrect- Error handling uses
http.Errorwhile success path uses buffer, leading to inconsistent behaviorHere's the suggested fix:
func SendResponse[T any](w http.ResponseWriter, code int, data T, errs []Error, meta *Meta) { w.Header().Set("Content-Type", "application/json; charset=utf-8") response := &Response[T]{ Data: data, Errors: errs, Meta: meta, } - // Set the status code after encoding to ensure no issues with writing the response body - w.WriteHeader(code) - // Attempt to encode the response as JSON var buffer bytes.Buffer if err := json.NewEncoder(&buffer).Encode(response); err != nil { log.Printf("Error writing response: %v", err) - errResponse := `{"errors":[{"code":500,"message":"Internal Server Error"}]}` - http.Error(w, errResponse, http.StatusInternalServerError) + w.WriteHeader(http.StatusInternalServerError) + json.NewEncoder(w).Encode(&Response[T]{ + Errors: []Error{{ + Code: http.StatusInternalServerError, + Message: "Internal Server Error", + }}, + }) return } // Set the status code after success encoding w.WriteHeader(code) // Write the encoded response to the ResponseWriter if _, err := w.Write(buffer.Bytes()); err != nil { log.Printf("Error writing response: %v", err) + // Note: Cannot change status code here as headers are already sent } }This change:
- Removes the redundant
WriteHeadercall- Makes error handling consistent with the success path by using the same Response structure
- Sets status code before writing the response body

75-77: Consider improving error handling for write operationsThe current implementation only logs write errors but can't properly handle them since headers are already sent. Consider adding monitoring or metrics for these errors to track potential issues.
if _, err := w.Write(buffer.Bytes()); err != nil { - log.Printf("Error writing response: %v", err) + // Consider using your application's metrics/monitoring system + log.Printf("Failed to write response body (status=%d): %v", code, err) + metrics.IncCounter("response_write_errors") }

52-52: LGTM! Charset addition meets the requirements.
The Content-Type header now correctly includes the UTF-8 charset specification as required.
Let's verify there are no other Content-Type headers that need similar updates:
✅ Verification successful
Content-Type headers in test files don't require charset updates
The search results show that all other occurrences of Content-Type: application/json headers are in test files (request_test.go). Test files typically don't require charset specifications as they're just simulating HTTP requests for testing purposes. The actual response header in response.go has been correctly updated.

17-43: Consider enhancing test case names for better clarity.While the test cases are well-structured, consider making the test names even more descriptive by including the expected outcome in the name. For example:
- name: "200 OK with TestResponse body", + name: "should return 200 OK with JSON response when given valid TestResponse",This makes it clearer what the test is verifying and what behavior to expect.

Line range hint 16-65: LGTM! Comprehensive test coverage.
The test cases effectively cover various scenarios including:
- Success responses with different payload types
- Error responses with different status codes
- Responses with pagination metadata
- Multiple error messages
70-70: LGTM! Content-Type header assertion correctly updated.
The assertion now properly validates the charset specification in the Content-Type header, aligning with the PR objective and the solution proposed in issue #5.
Let's verify that this is the only place where Content-Type assertions need to be updated:
✅ Verification successful
Content-Type header assertions are correctly scoped
The Content-Type assertions in request_test.go are for setting request headers in test setup, not for validating response headers. The original review comment correctly focused on the response header assertion in response_test.go. No additional changes are needed.

This PR adds the chatset as utf-8 to all responses.
Closes #5
