886-902: LGTM! Consider adding a brief comment.The implementation of the
CBORmethod looks good. It follows the pattern of similar methods likeJSON, handles errors appropriately, and allows for custom content types. The use ofSetBodyRawis efficient for setting the response body.Consider adding a brief comment explaining the purpose of this method, similar to other methods in this file. For example:
// CBOR converts any interface or string to CBOR encoded bytes and sets it as the response body. // If the ctype parameter is given, it sets the Content-Type header to the provided value. // Otherwise, it sets the Content-Type header to "application/cbor". func (c *DefaultCtx) CBOR(data any, ctype ...string) error { // ... (existing implementation) }

1048-1066: Consider improving error handling in the JSON methodFor consistency with the newly added
CBORmethod, consider updating theJSONmethod to return an error. This would allow for better error handling when JSON encoding fails.Here's a suggested modification to the
JSONmethod:-func (c *DefaultCtx) JSON(data any, ctype ...string) error { +func (c *DefaultCtx) JSON(data any, ctype ...string) error { raw, err := c.app.config.JSONEncoder(data) if err != nil { - return err + return fmt.Errorf("failed to encode JSON: %w", err) } c.fasthttp.Response.SetBodyRaw(raw) if len(ctype) > 0 { c.fasthttp.Response.Header.SetContentType(ctype[0]) } else { c.fasthttp.Response.Header.SetContentType(MIMEApplicationJSON) } return nil }This change would make the error handling more informative and consistent with the new

321-334: Ensure comments for CBOR encoder and decoder fields are clear and consistentThe comments for
CBOREncoderandCBORDecoderin theConfigstruct could be improved for clarity and consistency with existing documentation comments. Consider revising the comments to match the style of other encoder/decoder fields.Apply this diff to adjust the comments:

middleware/cache/manager_msgp.go (3)
55-57: Approve: Improved nil handling in headers mapThis change enhances the robustness of the
DecodeMsgmethod by ensuring that no nil values are stored in theheadersmap. By initializing nil byte slices to empty slices, it maintains consistency in the data structure and potentially prevents nil pointer dereferences in code that uses these headers. This is a good practice for handling potentially nil values.
273-275: Approve: Consistent nil handling in UnmarshalMsgThis change in the
UnmarshalMsgmethod mirrors the improvement made inDecodeMsg. It ensures consistent handling of nil values across different serialization operations, maintaining data integrity and preventing potential issues with nil values in theheadersmap. This consistency is crucial and demonstrates a thorough approach to the nil-value handling enhancement.
55-57: Summary: Improved robustness in cache serializationThese changes enhance the reliability of the caching mechanism by ensuring consistent handling of nil values in the
headersmap during both decoding and unmarshaling operations. While not directly related to CBOR encoding, this improvement aligns with the PR's objective of enhancing data handling capabilities within the framework. It provides a more robust foundation for interacting with various data formats, including CBOR, by ensuring that the underlying data structures are always in a consistent state.The nil-to-empty-slice conversion simplifies error handling for consumers of this cache data, as they can now assume that header values are always valid byte slices. This could lead to more predictable behavior and easier integration with new features like CBOR encoding.
While there might be a negligible performance impact due to the additional nil checks and potential memory allocations for empty slices, the benefits in terms of increased robustness and consistency outweigh this minor concern.

constants.go (2)
26-26: LGTM: Correct MIME type constant for CBOR addedThe addition of
MIMEApplicationCBORconstant with the value"application/cbor"is correct and consistent with the existing MIME type constants in the file. This constant will be useful for setting the appropriate Content-Type header when sending CBOR-encoded responses.
26-26: Summary: Minimal, focused change for CBOR supportThe addition of the
MIMEApplicationCBORconstant is the only change in this file. It's a minimal and focused modification that supports the PR's objective of adding CBOR encoding capabilities. The change maintains backward compatibility and follows existing patterns in the codebase.ctx_interface_gen.go (3)
166-170: New CBOR method added to Ctx interfaceThe addition of the
CBORmethod to theCtxinterface is consistent with the existing pattern for other data serialization methods likeJSONandXML. This enhancement allows for encoding response bodies in CBOR format, which aligns with the PR objectives.A few observations:
- The method signature
CBOR(data any, ctype ...string) erroris consistent with other serialization methods in the interface.- The comment describes the functionality and default behavior for the Content-Type header, which is helpful for developers.
To ensure consistency across the codebase, let's verify the implementation of this method:
#!/bin/bash # Search for the CBOR method implementation rg -p 'func \(c \*DefaultCtx\) CBOR\(' --type go
Line range hint
1-170: Summary of changes to ctx_interface_gen.goThe changes to this file are minimal but significant:
- A new
CBORmethod has been added to theCtxinterface, enhancing the framework's serialization capabilities.- The addition is consistent with existing patterns and doesn't break the interface contract.
Overall, this change successfully implements part of the PR's objective to allow encoding response bodies in CBOR format. The integration is clean and follows the established conventions of the
fiberpackage.To ensure full implementation:
Let's check for any related configuration options or utilities added for CBOR support:
#!/bin/bash # Search for CBOR-related additions in other files rg -p 'CBOR' --type go
Line range hint
1-170: Overall interface consistency and documentation considerationsThe addition of the
CBORmethod to theCtxinterface is well-integrated and consistent with the existing design. It follows the same pattern as other serialization methods likeJSON,JSONP, andXML.Considerations:
- The interface remains backwards-compatible as the new method doesn't alter existing method signatures.
- The placement of the
CBORmethod alongside other serialization methods enhances discoverability for developers.Consider updating the package documentation and examples to include usage of the new CBOR functionality. This will help developers understand how to utilize this new feature effectively.
Let's check if the documentation has been updated:
ctx.go (1)
Line range hint
1-3140: Overall, the changes look good with minor suggestions for improvementThe addition of the
CBORmethod to theDefaultCtxstruct is well-implemented and consistent with the existing codebase. The suggested improvements (adding a comment to theCBORmethod and updating theJSONmethod's error handling) would enhance the code's documentation and consistency.No other significant issues were found in the surrounding code. The file maintains a good structure and follows consistent patterns throughout.
app.go (2)
26-26: Import statement added appropriatelyThe import of
github.com/fxamacker/cbor/v2is necessary to support CBOR encoding and decoding functionalities.
552-557: Default CBOR encoder and decoder are correctly initializedThe default CBOR encoder and decoder are properly set to
cbor.Marshalandcbor.Unmarshalif they are not provided in the configuration, ensuring consistent behavior.ctx_test.go (3)
15-15: Import of "encoding/hex" is appropriateThe addition of
"encoding/hex"to the imports is necessary for encoding CBOR outputs to hex strings in the tests.
3576-3631: CBOR test functions are well implementedThe
Test_Ctx_CBORfunction provides comprehensive tests for the CBOR encoding functionality. It covers various cases including complex numbers, different data types, custom content types, empty values, and custom CBOR encoders. The tests are well-structured and follow existing patterns in the codebase.
3633-3655: Benchmark function for CBOR encoding is properly structuredThe
Benchmark_Ctx_CBORfunction effectively measures the performance of CBOR encoding. It aligns with the standard benchmarking practices used in the codebase, ensuring consistency and reliability of benchmark results.

binder/cbor.go (1)
1-15: Consider adding unit tests and documentation.As this is a new binding implementation, please ensure:
- Add comprehensive unit tests covering both success and error cases
- Add godoc comments explaining the binding's purpose and usage
- Update the framework's documentation to include CBOR binding examples
- Consider adding benchmarks to compare with other binding implementations
Would you like me to help generate:
- Unit test cases?
- Documentation examples?
- Benchmark tests?
client/response.go (1)
78-81: Enhance method documentation for better clarity.The implementation looks good and follows the established pattern of other unmarshal methods. Consider enhancing the documentation to provide more details about the CBOR unmarshaling process and any potential errors that might be returned.
-// CBOR method will unmarshal body to cbor. +// CBOR method unmarshals the response body as CBOR into the given value. +// It uses the client's CBOR unmarshaler to decode the response body. +// Returns an error if the unmarshaling fails.bind.go (1)
123-128: Add documentation and ensure test coverage.Please consider the following improvements:
- Add documentation comments for the CBOR method explaining:
- Purpose and usage
- Any specific CBOR encoding considerations
- Example usage if helpful
- Ensure comprehensive test coverage in
bind_test.go:
- Basic CBOR binding
- Error cases
- Performance benchmarks comparing with JSON
Example documentation:
+// CBOR binds CBOR-encoded body data into the provided struct. +// The binding uses the application's configured CBORDecoder for custom decoding if provided. func (b *Bind) CBOR(out any) error {client/hooks.go (1)
133-134: Consider setting Accept header for consistencyWhile the CBOR case correctly sets the Content-Type header, consider setting the Accept header to match the pattern used in the JSON case for consistency:
case cborBody: req.RawRequest.Header.SetContentType(applicationCBOR) + req.RawRequest.Header.Set(headerAccept, applicationCBOR)client/client.go (2)
155-175: Fix documentation comments referencing XML instead of CBORThe documentation comments for CBOR methods incorrectly reference XML. This should be updated to maintain accuracy.
Update the comments as follows:
-// CBORMarshal returns xml marshal function in Core. +// CBORMarshal returns CBOR marshal function in Core. -// SetCBORMarshal Set xml encoder. +// SetCBORMarshal Set CBOR encoder. -// CBORUnmarshal returns xml unmarshal function in Core. +// CBORUnmarshal returns CBOR unmarshal function in Core. -// SetCBORUnmarshal Set xml decoder. +// SetCBORUnmarshal Set CBOR decoder.

607-608: Consider adding CBOR support to Config structThe
Configstruct andsetConfigToRequestfunction currently default to JSON serialization for the Body field. Consider adding support for CBOR serialization to maintain consistency with the new CBOR functionality.Consider adding a field to specify the serialization format:
type Config struct { Body any + // BodyFormat specifies the serialization format (e.g., "json", "xml", "cbor") + BodyFormat string // ... rest of the fields }Then update
setConfigToRequest:if cfg.Body != nil { + switch cfg.BodyFormat { + case "cbor": + req.SetCBOR(cfg.Body) + case "xml": + req.SetXML(cfg.Body) + default: req.SetJSON(cfg.Body) + } return }client/request.go (2)
341-345: Add documentation comments for consistency.Other methods in this file include documentation comments. Consider adding a comment to describe the CBOR functionality:
+// SetCBOR method sets CBOR body in request. func (r *Request) SetCBOR(v any) *Request {
341-345: LGTM! Consider adding validation for better error handling.The implementation correctly follows the established pattern. However, consider adding validation to ensure the input can be properly encoded to CBOR:
func (r *Request) SetCBOR(v any) *Request { + if v == nil { + return r + } r.body = v r.bodyType = cborBody return r }bind_test.go (3)
15-15: Use an import alias for clarityConsider adding an alias for the
cborpackage to improve code readability and avoid potential naming conflicts.Apply this diff to add an import alias:
- "github.com/fxamacker/cbor/v2" + cbor "github.com/fxamacker/cbor/v2"
1103-1131: Handle errors consistently in benchmarksIn the
Benchmark_Bind_Body_CBORfunction, consider usingb.Fatalfinstead ofb.Errorto halt the benchmark immediately if marshalling fails. This ensures that the benchmark does not continue running with invalid data.Apply this diff for consistent error handling:
body, err := cbor.Marshal(&Demo{Name: "john"}) if err != nil { - b.Error(err) + b.Fatalf("Failed to marshal CBOR data: %v", err) }
1751-1760: Avoid duplicating error handling codeExtract the CBOR marshalling and error handling into a helper function to reduce code duplication and improve maintainability.
Create a helper function:
func marshalCBOR(t *testing.T, v interface{}) []byte { enc, err := cbor.Marshal(v) if err != nil { t.Fatal(err) } return enc }Modify your test code to use the helper function:
- cb, err := cbor.Marshal(&Request{ + cb := marshalCBOR(t, &Request{ BodyParam: "body_param", -}) -if err != nil { - t.Error(err) -} +})Update the call to
testDecodeParser:- testDecodeParser(MIMEApplicationCBOR, string(cb)) + testDecodeParser(MIMEApplicationCBOR, cb)Ensure
testDecodeParseraccepts a byte slice:-func testDecodeParser(contentType, body string) { +func testDecodeParser(contentType string, body []byte) {

7-7: LGTM! Clean type definition.
The empty struct is an appropriate choice for a stateless binding implementation.
13-15: 🛠️ Refactor suggestion
Consider adding input validation.
The Bind method directly passes the input to the decoder without any validation. Consider adding checks for:
- nil body
- empty body
- nil decoder function
- nil output parameter
Here's a suggested implementation:
func (*cborBinding) Bind(body []byte, cborDecoder utils.CBORUnmarshal, out any) error {
+ if len(body) == 0 {
+ return nil
+ }
+ if cborDecoder == nil {
+ return fmt.Errorf("cbor decoder is nil")
+ }
+ if out == nil {
+ return fmt.Errorf("output parameter is nil")
+ }
return cborDecoder(body, out)

78-81: Verify client's CBOR unmarshal implementation.
The method relies on client.cborUnmarshal. Let's verify its implementation to ensure proper CBOR support.
✅ Verification successful
CBOR implementation is properly supported and configured
The codebase has comprehensive CBOR support with proper implementation:
- The client uses
fxamacker/cbor/v2library for CBOR encoding/decoding - CBOR functionality is properly initialized in the client:
cborUnmarshalis a configurable field in the Client struct- Default CBOR decoder is set to
cbor.Unmarshalif not explicitly configured - Custom CBOR decoder can be set via
SetCBORUnmarshalmethod

✅ Verification successful
Based on the search results, I can now provide a final response since I have found sufficient evidence about the CBOR decoder initialization:
CBORDecoder is properly initialized with default implementation
The implementation is verified to be correct:
- CBORDecoder is defined in the Config struct with type
utils.CBORUnmarshal - Default initialization is handled in app.go:
if app.config.CBORDecoder == nil { app.config.CBORDecoder = cbor.Unmarshal } - This follows the same pattern as other decoders (JSON, XML) in the framework

Avoid converting CBOR binary data to a string
CBOR data is binary, and converting it to a string can lead to data corruption or unexpected behavior. Modify testDecodeParser to accept a byte slice instead of a string to handle binary data properly.
Refactor testDecodeParser to accept []byte for the body parameter:
-func testDecodeParser(t *testing.T, contentType, body string) {
+func testDecodeParser(t *testing.T, contentType string, body []byte) {
t.Helper()
c := app.AcquireCtx(&fasthttp.RequestCtx{})
c.Request().Header.SetContentType(contentType)
- c.Request().SetBody([]byte(body))
+ c.Request().SetBody(body)
c.Request().Header.SetContentLength(len(body))
d := new(Demo)
require.NoError(t, c.Bind().Body(d))
require.Equal(t, "john", d.Name)
}Update the test case to pass the byte slice directly:
- str := string(enc)
- testDecodeParser(t, MIMEApplicationCBOR, str)
+ testDecodeParser(t, MIMEApplicationCBOR, enc)📝 Committable suggestion

3619-3679: Consider expanding test coverage for CBOR encodingThe test cases look good but could be enhanced for more thorough coverage:
- Add test cases for complex nested structures and arrays
- Add test cases for all primitive types (bool, int8/16/32/64, uint8/16/32/64, float32/64)
- Add test cases for concurrent encoding to verify thread safety
- Add test cases for handling nil values in nested structures
Example test case for nested structure:
type NestedStruct struct { Name string Age int IsActive bool Tags []string Metadata map[string]interface{} } data := NestedStruct{ Name: "John", Age: 30, IsActive: true, Tags: []string{"user", "admin"}, Metadata: map[string]interface{}{ "lastLogin": time.Now(), "visits": 42, }, } err := c.CBOR(data)

26-26: LGTM! Good choice of CBOR library.
The fxamacker/cbor library is a well-maintained and widely-used implementation of CBOR for Go.
321-334: LGTM! Well-structured Config additions.
The new CBOR configuration fields follow the established pattern of existing encoder/decoder fields. The documentation is clear and the types allow for custom implementations, maintaining flexibility.
552-557: LGTM! Proper initialization of CBOR encoders/decoders.
The default initialization follows the established pattern and uses appropriate default implementations from the CBOR library.
321-334: Verify complete CBOR integration across the framework.
While the core CBOR support is well implemented, ensure that CBOR handling is consistently implemented across all necessary components.
Also applies to: 552-557
✅ Verification successful
CBOR integration is complete and well-implemented across the framework
The verification shows comprehensive CBOR support across all necessary components:
- CBOR binding implementation exists in
binder/cbor.go - CBOR binding method is properly integrated in
bind.go - CBOR response method is available in
ctx.go - CBOR support is present in client components
- The implementation follows the same pattern as other formats (JSON, XML) with consistent integration across binding, context, and client layers
The framework provides complete CBOR support with proper integration across all required components, matching the implementation pattern of other supported formats.

726-727: Consider enhancing Config struct for CBOR support.The current implementation allows setting CBOR functions but doesn't provide a way to specify CBOR as the preferred encoding in the Config struct. Consider:
- Adding a ContentType field to Config to allow specifying the encoding (JSON/XML/CBOR)
- Updating setConfigToRequest to handle CBOR encoding when specified
This would make CBOR support more accessible in the convenient request methods (Get, Post, etc.).

🛠️ Refactor suggestion
Enhance error handling test coverage
The error test for complex numbers is good, but should be expanded to cover more error cases:
- Test encoding of channels (should error)
- Test encoding of functions (should error)
- Test encoding of recursive structures (should error)
- Test encoding of very large numbers that may overflow
// Test invalid types
err = c.CBOR(make(chan int))
require.Error(t, err)
err = c.CBOR(func() {})
require.Error(t, err)
// Test recursive struct
type Recursive struct {
Next *Recursive
}
r := &Recursive{}
r.Next = r
err = c.CBOR(r)
require.Error(t, err)
Description
Adds support for CBOR encoding and decoding through Gofiber.
