hRPC

A simple RPC system using protocol buffers over HTTP and WebSockets

hRPC was designed to be used as a very simple alternative to gRPC. gRPC streams are known to be problematic due to how they were designed to be long-living, so as a result hRPC was born.

Supported Languages

hRPC was made with the intention to be as simple as possible, so creating a code generator / transport isn't actually that scary. That said, we have already built with hRPC using the following languages:

• Rust (using hrpc-rs)
• TypeScript (using @harmony-dev/hrpc)
• C++ (using protoc-gen-hrpc with --hrpc_opt="cpp_client")
• C# (using protoc-gen-hrpc with --hrpc-opt="csharp_client" or --hrpc-opt="csharp_server", and hrpc.net wrapper)
• Dart (using protoc-gen-hrpc with --hrpc_opt="dart_client")
• Elixir (using protoc-gen-hrpc with --hrpc_opt="elixir_server")

WIP Languages

• Go (using protoc-gen-go-hrpc not protoc-gen-hrpc)

Examples

Example applications are located at the hRPC examples repository.

Protocol and Spec

See the protobuf files in protocol. That folder also contains documentation regarding to hRPC.
