Custom JSON Formats vs Protobuf

Developers should learn and use custom JSON formats when building systems that require consistent, validated data interchange, such as RESTful APIs, microservices communication, or configuration management, to prevent errors and ensure interoperability meets developers should learn and use protobuf when building high-performance, scalable distributed systems, microservices, or apis where efficient data serialization and low latency are critical, such as in real-time applications, iot devices, or large-scale data processing pipelines. Here's our take.

Custom JSON Formats

Nice Pick

Developers should learn and use custom JSON formats when building systems that require consistent, validated data interchange, such as RESTful APIs, microservices communication, or configuration management, to prevent errors and ensure interoperability

Pros

• They are essential in scenarios like defining API request/response payloads, where structured data with specific fields (e
• Related to: json-schema, rest-api

Cons

• Specific tradeoffs depend on your use case

Protobuf

Developers should learn and use Protobuf when building high-performance, scalable distributed systems, microservices, or APIs where efficient data serialization and low latency are critical, such as in real-time applications, IoT devices, or large-scale data processing pipelines

Pros

• It is particularly valuable in environments with bandwidth constraints or when interoperability between multiple programming languages is required, as it generates type-safe code and ensures backward and forward compatibility through schema evolution
• Related to: grpc, serialization

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Custom JSON Formats is a concept while Protobuf is a tool. We picked Custom JSON Formats based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Custom JSON Formats wins

Based on overall popularity. Custom JSON Formats is more widely used, but Protobuf excels in its own space.
