Go gRPC Examples

This repository contains simple and educational examples of using gRPC in Go. It covers various RPC patterns including unary, client streaming, server streaming, and bidirectional streaming.

Prg01: Unary RPC – Square Calculation

• The server listens on port 50051.
• The client sends a single integer value (e.g., 4) to the server.
• The server responds with the square of the number (e.g., 16).

Prg02: Bidirectional Streaming

• The server listens on port 50051.
• The client establishes a bidirectional stream with the server.
• Both client and server send 5 messages to each other through the stream.

Prg03: Client Streaming

• The server listens on port 50051.
• The client streams multiple messages to the server.
• The server counts the number of received messages.
• When the client finishes (EOF), the server responds with the total count.

Prg04: Server Streaming

• The server listens on port 50051.
• The client sends a single number (e.g., 5) to the server.
• The server logs the number and streams 5 messages back to the client.

Each program demonstrates how to implement and run different types of gRPC functions using Go.

Run Instructions

For each program:

# Run server
go run server.go

# Run client
go run client.go
