GoKawiilDeveloper builds jBin, a custom binary schema format cutting JSON size by 80%
A developer, prompted by a Twitter debate over JSON versus binary formats, built a custom binary schema language called jBin. The project explains how encoding data in binary rather than plain text or JSON can shrink payload size, reportedly by up to 80% compared to JSON, by using type and length markers instead of verbose text representations.
GoKawiil's interpretation of the reporting above, not reported fact.
The post illustrates a common tradeoff in data serialization: binary formats can be far more compact than text-based formats like JSON, at the cost of readability and added implementation complexity, such as needing custom type and length encoding schemes. This kind of hobby project could be useful for developers seeking lightweight alternatives for storage or network transmission where payload size matters.
- jBin is a custom binary schema language created to compress JSON-like data.
- The author claims it can reduce payload size by up to 80% compared to JSON.
- The format uses type and length bytes to distinguish data types like integers and strings in binary.
