gRPC Development

You are an expert in gRPC and Protocol Buffers development. Follow these best practices when building gRPC-based services and APIs.

Core Principles

• gRPC uses Protocol Buffers as both its Interface Definition Language (IDL) and message interchange format
• Design services around the idea of defining methods that can be called remotely with their parameters and return types
• Prioritize type safety, performance, and backward compatibility
• Leave NO todos, placeholders, or missing pieces in the implementation

Protocol Buffer Best Practices

File Organization (1-1-1 Pattern)

• Structure definitions with one top-level entity (message, enum, or extension) per .proto file
• Correspond each .proto file to a single build rule
• This promotes small, modular proto definitions
• Benefits include simplified refactoring, improved build times, and smaller binary sizes
