taylortrimble / framing.proto
Created February 21, 2017 00:32
An idea for framing gRPC requests from JavaScript WebSockets to a generic proxy.
syntax = "proto3";
option go_package = "proxy";
// Frames an API request message.
//
// Each request to the API has a unique stream id per-connection, starting at one.
// This stream id associates all request and response messages for a single request
// together.
