Protocol Buffers

For Go developers working with Protocol Buffers, ensuring data integrity is crucial. While Protobufs guarantee type safety, they don’t enforce semantic rules out of the box. This is where protocheck comes in, a lightweight and powerful tool for adding validation logic to your Protobuf messages.

This blog post will explore the design choices behind protocheck, focusing on its simplicity of declaration and code generation. We’ll also compare it to bufbuild/protovalidate to help you choose the right tool for your project.
