A simple library to encode nested hash to grpc object and vice versa

grpc_serializer

A simple Ruby gem for nested grpc message encoding and decoding

Usage

$ gem install grpc_serializer

Sample Proto file (.proto) :

      syntax = "proto3";

       package cpqgrpc.product.v1;

       message Shop {
          string name = 1;   
          repeated string items = 2
       }

       message ProductRequest {
         uint64 id = 2;
         string name = 3;
         repeated string categories = 4;
         Shop shop = 5
       }

Use the generated stub class ProductRequest as follows. Do deep_symbolize_keys before sending as argument

payload:

  {
    id: 1,
    name: "Macbook"
    categories: ["accessories", "electronics"],
    shop: {
      name: "shop 1",
      items: ["item1", "item2"]  
    }
  }

grpc_msg = GrpcSerializer.hash_to_grpc_object(payload, ProductRequest)

To decode to hash on client or server

hash = GrpcSerializer.grpc_object_to_hash(grpc_msg, ProductRequest)
