: LGTM! Consider adding a brief comment.The implementation of the
CBOR
method looks good. It follows the pattern of similar methods likeJSON
, handles errors appropriately, and allows for custom content types. The use ofSetBodyRaw
is 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) }

: Consider improving error handling in the JSON methodFor consistency with the newly added
CBOR
method, consider updating theJSON
method to return an error. This would allow for better error handling when JSON encoding fails.Here's a suggested modification to the
JSON
method:-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

: Approve: Improved nil handling in headers mapThis change enhances the robustness of the
DecodeMsg
method by ensuring that no nil values are stored in theheaders
map. 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
UnmarshalMsg
method 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 theheaders
map. 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
headers
map 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.

: LGTM: Correct MIME type constant for CBOR addedThe addition of
MIMEApplicationCBOR
constant 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
MIMEApplicationCBOR
constant 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
CBOR
method to theCtx
interface is consistent with the existing pattern for other data serialization methods likeJSON
andXML
. 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) error
is 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
CBOR
method has been added to theCtx
interface, 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
fiber
package.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

: Overall interface consistency and documentation considerationsThe addition of the
CBOR
method to theCtx
interface 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
CBOR
method 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:

: Overall, the changes look good with minor suggestions for improvementThe addition of the
CBOR
method to theDefaultCtx
struct is well-implemented and consistent with the existing codebase. The suggested improvements (adding a comment to theCBOR
method and updating theJSON

✅ Verification successful
CBOR implementation is properly supported and configured
The codebase has comprehensive CBOR support with proper implementation:
- The client uses
fxamacker/cbor/v2
library for CBOR encoding/decoding - CBOR functionality is properly initialized in the client:
cborUnmarshal
is a configurable field in the Client struct- Default CBOR decoder is set to
cbor.Unmarshal
if not explicitly configured - Custom CBOR decoder can be set via
SetCBORUnmarshal
method

💡 Codebase verification
Additional imports are required for CBOR functionality
The current implementation is missing the required CBOR package import. Based on the codebase analysis:
- The main CBOR functionality uses
github.com/fxamacker/cbor/v2
as seen inapp.go
andbind_test.go
- The implementation relies on
utils.CBORUnmarshal
type fromgofiber/utils/v2
, but the actual CBOR decoding is handled by the external CBOR package
Suggested changes:
- Add
github.com/fxamacker/cbor/v2
to the imports
🔗 Analysis chain
Verify if additional CBOR-related imports are needed.
The current implementation only imports utils/v2
. Consider if we need to import any CBOR-specific packages or testing packages for unit tests.

🛠️ Refactor suggestion
Enhance CBOR test coverage with more comprehensive test cases.
While the basic test structure is good, consider the following improvements:
- Add test cases with more complex CBOR data structures (e.g., maps, arrays, nested objects) to ensure proper encoding.
- Use a more specific error message in the error test case to indicate CBOR-specific issues.
- Add test cases that verify the actual CBOR encoding/decoding logic, not just the marshaling function plumbing.
Here's an example of a more comprehensive test case:
t.Run("set cbor marshal", func(t *testing.T) {
t.Parallel()
- bs, err := hex.DecodeString("f6")
+ // Test complex CBOR data
+ // a2 # map(2)

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)

: 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

✅ 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

- 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.
