Hey @cnlangzi - I've reviewed your changes - here's some feedback:
Overall Comments:
- There's an inconsistency in the ResponseWriter naming - the type was renamed to stdResponseWriter but some references still use responseWriter. These should be updated for consistency.

question (bug_risk): Returning empty URL instead of nil may mask errors.
Returning an emptyURL instead of nil in RequestReferer changes the function's semantics. This might mask errors where a nil return was expected to indicate the absence of a referer. Consider whether this change aligns with the intended design.

issue (bug_risk): Consider keeping the panic on view loading errors during initialization
Just logging view loading errors during app initialization could mask serious problems that should prevent the app from starting. These are likely fatal errors that indicate misconfiguration.

suggestion: Consider handling view engine load failures more robustly
Simply logging the error and continuing could lead to undefined behavior if critical views aren't loaded. Consider either maintaining the panic for critical failures or implementing a more graceful degradation strategy.

suggestion: Reconsider changing return type from *url.URL to string
Returning a string instead of *url.URL makes the API less useful as callers lose access to parsed URL components and validation. Consider keeping the original return type unless there's a compelling performance reason.
Suggested implementation:
// RequestReferer returns the referer of the request as a parsed URL.
// Returns nil if the referer is empty or invalid.
func (c *Context) RequestReferer() *url.URL {
var v string
if c.app.interceptor != nil {
v = c.app.interceptor.RequestReferer(c)
} else {
v = c.req.Header.Get("Referer")
}
if v == "" {
return nil
}
u, err := url.Parse(v)
if err != nil {
return nil
}
return uMake sure to import "net/url" if it's not already imported in the file.

suggestion (testing): Add tests for edge cases.
Consider adding tests for edge cases like invalid URLs, different HTTP methods, and error handling within the interceptor.
Suggested implementation:
func TestHtmxInterceptor(t *testing.T) {
m := http.NewServeMux()
tests := []struct {
name string
method string
url string
headers map[string]string
expectedStatus int
expectedError bool
}{
{
name: "Valid GET request",
method: "GET",
url: "/test",
headers: map[string]string{"HX-Request": "true"},
expectedStatus: http.StatusOK,
expectedError: false,
},
{
name: "Invalid URL",
method: "GET",
url: "http://invalid\x7f.com",
headers: map[string]string{"HX-Request": "true"},
expectedStatus: http.StatusBadRequest,
expectedError: true,
},
{
name: "Missing HTMX headers",
method: "GET",
url: "/test",
headers: map[string]string{},
expectedStatus: http.StatusBadRequest,
expectedError: true,
},
{
name: "POST request",
method: "POST",
url: "/test",
headers: map[string]string{"HX-Request": "true"},
expectedStatus: http.StatusOK,
expectedError: false,
},
{
name: "PUT request",
method: "PUT",
url: "/test",
headers: map[string]string{"HX-Request": "true"},
expectedStatus: http.StatusOK,
expectedError: false,
},
{
name: "DELETE request",
method: "DELETE",
url: "/test",
headers: map[string]string{"HX-Request": "true"},
expectedStatus: http.StatusOK,
expectedError: false,
},
}
for _, tt := range tests {
t.Run(tt.name, func(t *testing.T) {
req := httptest.NewRequest(tt.method, tt.url, nil)
for key, value := range tt.headers {
req.Header.Set(key, value)
}
w := httptest.NewRecorder()
handler := xun.NewChain(HtmxInterceptor()).Then(m)
handler.ServeHTTP(w, req)
if tt.expectedError {
require.Equal(t, tt.expectedStatus, w.Code)
} else {
require.Equal(t, tt.expectedStatus, w.Code)
require.Equal(t, "true", w.Header().Get("HX-Request"))
}
})
}The developer will need to:
- Ensure the HtmxInterceptor properly handles these edge cases in the actual implementation
- Adjust the expected status codes and error conditions based on the actual implementation
- Add any additional specific headers or response body checks based on their HTMX implementation
- Consider adding more specific error cases based on their application's requirements
