Go_gRPC is a complete demonstration of building modern gRPC services in Go.
It includes all four types of gRPC calls:
- 🔹 Unary RPC — single request, single response.
- 🔸 Server Streaming RPC — single request, multiple responses.
- 🔸 Client Streaming RPC — multiple requests, single response.
- 🔹 Bidirectional Streaming RPC — multiple requests, multiple responses simultaneously.
"I want to understand, not to be understood."
This project was built to master gRPC concepts in Go by exploring each RPC type in detail, with clean modular code and full explanation.
git clone https://github.com/Girish070/Go_gRPC.git
cd Go_gRPC
2️⃣ Install dependencies
go mod tidy
3️⃣ Generate protobuf code
protoc --go_out=. --go-grpc_out=. proto/great.proto
💻 Running the Project
Start server
cd server
go run *.go
Run client
cd client
go run *.go
⚡ Switch between RPC types
In client/main.go, choose which RPC call to execute:
callSayHello(client)
callSayHelloServerStream(client, names)
callSayHelloClientStream(client, names)
callHelloBidirectionalStream(client, names)
Uncomment the desired call and comment the others.
