This is a basic gRPC server and client written in Go. It is based on the gRPC Quickstart and gRPC Basics: Go tutorials.

Implemented a simple gRPC server and client with the following functionality:

• simple RPC
• server-side streaming RPC
• client-side streaming RPC
• bidirectional streaming RPC

1. Create a new directory for your project and cd into it

mkdir basic-go-grpc
cd basic-go-grpc
mkdir client server proto

2. Installing the gRPC Go plugin

go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.28

go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.2

choco install protoc 

note that choco supports windows only.

3. Initialize a Go module

go mod init example.com/your-project-name/proto

go mod tidy

4. Create the proto file with the required services and messages in the proto directory

5. Generate .pb.go files from the proto file

depending on what path you mention in your greet.proto file, you will either run this -

protoc --go_out=. --go-grpc_out=. proto/greet.proto

6. Create the server and client directories and create the main.go files with necessary controllers and services

1. Install the dependencies

go mod tidy

2. Run the server

cd server
go run .

3. Run the client

cd client
go run .
