Hang lava middleware on Mux.UseRPCMiddleware so unary and all stream modes share one chain for local and proxy backends, and always emit gRPC-Web trailer frames on success. Co-authored-by: Cursor <cursoragent@cursor.com>
Cache Operation at registration time and look up via Mux helpers so routerTree stays an HTTP index by FullMethod without duplicating schema. Co-authored-by: Cursor <cursoragent@cursor.com>
Wire gzip compressors into the HTTP/gRPC-Web framed path via grpc-encoding / grpc-accept-encoding and per-frame flags, keeping encoding headers out of trailer frames. Co-authored-by: Cursor <cursoragent@cursor.com>
Document UseRPCMiddleware, compression, and Operation as dispatch SSOT so public docs match the Phase 1–3 implementation. Co-authored-by: Cursor <cursoragent@cursor.com>
Wire NewGatewaySurface and UseRPCMiddleware into the multi-protocol example, expand verify for HTTP/gRPC-Web trailers and gzip, and document both example apps. Co-authored-by: Cursor <cursoragent@cursor.com>
Introduce a publishable JS client with createHttpJsonClient and createGrpcWebTransport, and rewire the grpcweb frontend example to consume it. Co-authored-by: Cursor <cursoragent@cursor.com>
Add createGatewayTransport (json/binary/text), JsonRpcTransport with NDJSON streams and errorpb parsing, and rework the grpcweb demo as an agentrun-style rpc facade. Co-authored-by: Cursor <cursoragent@cursor.com>
Check Close errors in tests/verify and drop the redundant Backend() conversion in TransparentHandler. Co-authored-by: Cursor <cursoragent@cursor.com>
Flush server-stream bodies through Fiber SendStreamWriter so subscribe-style WatchHello pushes reach the client incrementally, encode grpc-web-text as one continuous base64 stream, and expand the example/SDK coverage for unary, headers/trailers, and long-lived server streams.
