What is SimpleServerSetup?

SimpleServerSetup is an educational Python project that shows how to implement the interaction between clients and servers through two different communication modes (SSE and STDIO). The server provides basic calculator functions, supporting both real-time event push and traditional command-line input methods.

How to use SimpleServerSetup?

First, start the server, then choose to connect using the SSE client or the STDIO client. The SSE client is suitable for scenarios that require real-time updates, while the STDIO client is suitable for simple command-line interactions.

Applicable scenarios

Suitable for teaching demonstrations, learning the basics of network programming, understanding client-server architecture, and exploring the implementation methods of different communication modes.

Main features

Dual-mode communicationSupports both Server-Sent Events (SSE) and Standard Input/Output (STDIO) communication modes simultaneously

Calculator functionProvides basic mathematical operation functions, including addition, subtraction, multiplication, division, etc.

Real-time updatesThe SSE mode supports the server pushing real-time calculation results to the client

Advantages and limitations

Advantages

🚀 Simple Server Setup

A simple Python project demonstrating calculator operations through two client-server communication modes: Server-Sent Events (SSE) and Standard Input/Output (STDIO). This project is ideal for learning basic client-server architectures and dual-modal communication.

🚀 Quick Start

✨ Features

Demonstrates calculator operations using two communication modes: SSE and STDIO.
Suitable for learning basic client-server architectures.
Ensures consistent calculation behavior across different modes.

📦 Installation

Prerequisites:

Python 3.7 or higher

git clone https://github.com/DionBenFernandes-Dev/SimpleServerSetup.git
cd SimpleServerSetup
pip install -r requirements.txt

💻 Usage Examples

Basic Usage

Start the server:

python server.py

Advanced Usage

Use the STDIO client

python client-stdio.py

Follow the prompts to enter expressions and receive results immediately.

Use the SSE client

python client-sse.py

This client will connect to the server and handle calculations via SSE.

Key Terms

Server-Sent Events (SSE): A web technology that allows servers to push real-time updates to clients over HTTP.
Standard Input/Output (STDIO): A traditional command-line interaction method where users provide input via the keyboard, and results are displayed on the screen.

How the Project Runs

SimpleServerSetup allows you to run the calculator service in two modes:

SSE Mode:
- The server (server.py) starts an HTTP endpoint for SSE.
- The SSE client (client-sse.py) connects to the server, sends calculation requests, and receives real-time event stream results.
- Suitable for web-based applications that require real-time updates.
STDIO Mode:
- The server (server.py) can also handle requests from the command-line client (client-stdio.py).
- The client sends expressions via standard input and receives results via standard output.
- Ideal for quick local calculations directly from the terminal.
