Fork of encoding/json from Go standard library with extra features

JSON Xtra

Fork of encoding/json from Go v1.24 standard library with some extra features.

It behaves exactly as a standard encoding/json and passes all standard unit tests.

Yes, it was just "cp -r /usr/local/go/src/encoding/json/* ." from standard Go distribution.

Added Features

• "omitemptyenc" tag for omitting struct field(s) for json.Marshal() only
• "omitemptydec" tag for omitting struct field(s) for json.Unmarshal() only

Planned Features

• "emptyarr" tag for encoding empty array and slice struct fields as [] instead of "null"

Why?

When porting services written in one of the older JavaScript framework, we faced with problem that, when required fields we receive from API calls, read and write from/to database and return as a response were different.

So, instead of having duplicate data models or overwriting MarshalJSON() and UnmarshalJSON() for data models, this library fork was created.

It removes a lot of complexity from the code.
