gRPC CSV Reader

This is a gRPC CSV reader system that streams data from a server to a client. The server reads rows from a CSV file and streams them to the client via gRPC.

How to Run

1. Install Dependencies

Run the following command to install all required dependencies:

go mod tidy

2. Generate .pb.go Files (if needed)

If the files csv_reader.pb.go and csv_reader_grpc.pb.go are not already present in the proto/ folder, generate them using the this command:

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

3. Install Protocol Buffers Compiler and Plugins

Ensure the following tools are installed:

• Protocol Buffers Compiler (protoc): Install using Homebrew:

  brew install protobuf

• Protobuf Go Plugin (protoc-gen-go): Install with:

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

• gRPC Go Plugin (protoc-gen-go-grpc): Install with:

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

4. Add Go Binaries to PATH

Make sure the Go binaries are in your PATH environment variable. Run the this command:

export PATH=$PATH:$(go env GOPATH)/bin

Add this line to your shell configuration file (ie, .bashrc or .zshrc) to make it permanent:

echo 'export PATH=$PATH:$(go env GOPATH)/bin' >> ~/.zshrc

Reload your shell configuration:

source ~/.zshrc

5. Run the Server

Start the server by running:

go run main.go

You should see this message:

Server is running on port 50051...

6. Run the Client

Open a new terminal and run the client to fetch the CSV data:

go run client/client.go

You should now see the streamed rows from the server in the client’s output.
