pbts-grpc-transcoder

pbts-grpc-transcoder is a TypeScript library (v0.3.2) that provides gRPC-to-HTTP/1 JSON transcoding for protobuf.js, enabling fully-typed RPC calls over HTTP/1. It allows developers to make gRPC-style service calls using protobuf.js message types, which get automatically transcoded to HTTP/1 JSON requests based on google.api.http annotations in the service definition. Unlike envoy or grpc-gateway, this operates client-side, and is ideal for environments where HTTP/2 or gRPC-Web is unavailable. It requires protobuf.js as a peer dependency and uses a JSON descriptor file. Release cadence is low; no recent updates.
