gRPC Reverse Proxy with Go

This is a sample Go program that demonstrates a simple gRPC reverse proxy setup. The code consists of two main components: a gRPC server and a gRPC reverse proxy server. Components

1. gRPC Server

The server struct in the code represents a simple gRPC server with a SayHello method. This method responds to a client with a greeting. The server is intended to be running on port :50052, but it is currently commented out in the code. 2. gRPC Proxy Server

The proxyServer struct acts as a reverse proxy for the gRPC server. It forwards incoming gRPC requests to the actual gRPC server running on localhost:9090. The proxy server listens on port :8080. How to Run

Uncomment the code related to the gRPC server if you want to run it separately on port :50052.
Connect to the gRPC server by dialing its address (localhost:9090).
Create a gRPC proxy using the proxy.NewProxy function, passing the connection to the gRPC server.
Start the proxy server, listening on port :8080.
The reverse proxy is now running, forwarding requests from port :8080 to the gRPC server on localhost:9090.

Dependencies

The code uses the following external dependencies:

github.com/mwitkow/grpc-proxy/proxy: A package for creating a gRPC proxy server.
google.golang.org/grpc: The official gRPC Go implementation.

Run the Code

To run the code, execute the following steps:

bash

Clone the repository

git clone https://github.com/your-username/your-repository.git cd your-repository

Install dependencies

go get -u github.com/mwitkow/grpc-proxy/proxy go get -u google.golang.org/grpc

Run the code

go run main.go

Ensure that you have Go installed on your machine. Access the gRPC Server and Proxy

The gRPC server (if uncommented) is accessible at localhost:50052.
The gRPC reverse proxy is accessible at localhost:8080. It forwards requests to the gRPC server.
