The blog will provide insights about this project!

"Kaho aur Suno" (Hindi: कहो और सुनो, English: "Say and Listen") is a delightful showcase of a gRPC-based message broker. It provides examples of both the broker server and clients, all elegantly written in Go. It's important to note that this application is intended as a Proof of Concept and not suitable for production use.

Structure

This project has been divided into multiple sub-directories and is managed by a vscode workspace.

• proto: Contains protobuf files
• lib: Here's the generated proto packages goes in
  • go: The proto package for go. Designed as a local package and can be installed in standalone projects
• scripts/protogen.sh: Used to generate the proto package
• server: Server side implementation. To run the server, hit the command: go run main.go in it's directory
• client: Client side implementations
  • go: Implementation in Go (Root)
    • publisher: Publish messages, run: go run publisher/main.go
    • subsciber: Subscribe messages, run: go run subscibe/main.go <topic-name>

Extending

Right now the proto package and client implementations are only done in Go, however the directories are set up in a way that they can be later extended for other programming languages and/or use cases too!

This Message Broker is just a hobby project and not a production ready application at all. There are still multiple sectors in which we can improve it - like persisting messages, improved error handlings, message delivery acknowlegements, delayed delivery, etc. There are various industry grade Message Brokers like RabbitMQ, ActiveMQ, Google Pub/Sub etc. which implements such features!
