💫 Introduction

An application use gRPC to communicate between processes and allow users chat with each other.

What is gRPC?

gRPC (Google Remote Procedure Call) is an open-source, high-performance remote procedure call (RPC) framework developed by Google. It allows communication between client and server applications in a distributed system, enabling them to call methods or functions on remote systems as if they were local.

Key features of gRPC include: Language-agnostic, Protocol Buffers, Bi-directional Streaming, Strong Typing and Code Generation, Interoperability, Performance.

gRPC is widely used in various domains, including microservices architectures, cloud-native applications, and distributed systems. It simplifies the development of client-server communication, promotes code reusability, and enables the building of scalable and performant applications.

Why gRPC?

• Efficient Communication
• Language Agnostic
• Strong Typing and Code Generation
• Streaming and Real-Time Capabilities
• Performance and Scalability
• Extensibility and Interoperability

🧰 Getting Started

📌 Prerequisites

• Python: >= 3.10.7
• gRPC tools: gRPC compiler, Install here.

🦾 How to use gRPC

Step 1: Define your gRPC service using protocol buffers.

Refer to Service documentation for more information.

Step 2: Implement the server-side code for your gRPC service. This will handle incoming requests and provide responses. You can create a new process for each instance of your gRPC server.

Refer to Server documentation for more information.

Step 3: Implement the client-side code for your gRPC service. This will send requests to the server and receive responses. You can create one or more client processes as needed.

Refer to Client documentation for more information.

Step 4: Start the server process and client process(es).

🛠️ Run Locally

Install application

# Clone this repository
git clone https://github.com/QuanBlue/chat-grpc.git

# Go into the repository
cd chat-grpc

Run server

python3 ./server/_server.py

Run client (open new terminal)

python3 ./client/_client.py

Note: Run multiple client by using multiple terminal

💬 Command

We provide a CLI interface for the client. The CLI interface allows users to interact with the chat application with simple commands:

--like [user id]             like for user's message,
--name-len [limit length]    limit the length of the user name. Default is 10,
--frame-width [limit length]   limit the length of the frame. Default is 60,
--padding [limit length]     padding of the content in frame. Default is 2,
--history [limit length]     limit the number of messages in the chat history. Default is 9999,
--help                       show all commands with description,

🤖 Like message rule

LIKE reply: for allow user XX to continue chat (at least 2 LIKE)

Command: --like [user id]

Rule:

• Only LIKE once per user
• Can not LIKE your self

Example: --like 01
