Haleluak / gRPC

Create gRPC Server and Client in Go. We will create a fictional blockchain service.

Goal

Create gRPC Server and Client in Go. We will create a fictional blockchain service.

Steps

• Install protoc compiler.
• Install protoc-gen-go plugin: go get -u github.com/golang/protobuf/protoc-gen-go
• Define service definition in .proto file.
• Build Go bindings from .proto file. protoc --go_out=plugins=grpc:. proto/blockchain.proto
• Install grpc Go package - go get -u google.golang.org/grpc.
• Install context package - go get -u golang.org/x/net/context.
• Install protobuf package - go get -u github.com/golang/protobuf/proto
• Implement Server, interface BlockchainServer.
• Create a client using BlockchainClient.
• Run server first.
• Run client.

Usage

Start server:

go run server/main.go

Add block as client:

go run client/main.go --add

get blockchain as client:

go run client/main.go --list
