Protocol Buffers & gRPC Definition AST Inspection
Modern microservice architectures rely heavily on Protocol Buffers (Protobuf) for cross-language serialization and RPC contracts. Inspecting definitions and bridging between gRPC backends and TypeScript/JavaScript clients often introduces boilerplate friction.
Instant TypeScript & Mock JSON Generation
This lexer and AST parser translates .proto messages and enums into strongly typed TypeScript models and synthesized JSON mock fixtures with zero external tooling.
