protodef-protobuf

A transpiler and runtime for using Google Protocol Buffers (.proto files) with ProtoDef in Node.js. Version 1.0.0 is the current stable release; the package is actively maintained with an irregular release cadence (last two releases: 0.0.2 and 1.0.0). Key differentiators include support for Proto2 and Proto3, nested messages, enums, maps, packed repeated fields, extensions, imports (including Google well-known types), and a protobuf_message container for length-prefixing. It offers both a compiler mode for high performance via ProtoDef's AOT compiler and an interpreter mode for dynamic schemas. Compared to alternatives like protobuf.js or protobuf-es, this library integrates tightly with the ProtoDef ecosystem, making it suitable for projects already using ProtoDef for protocol definitions.
