SimpleServerSetup

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

Key Terms

• Server-Sent Events (SSE): A web technology enabling a server to push real-time updates to a client over HTTP.
• Standard Input/Output (STDIO): Traditional method for user interaction in the terminal, where input is provided via keyboard and output is printed to the screen.

How the Project Works

SimpleServerSetup allows you to run a 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 results as real-time event streams.
  • Useful for web-based or networked applications that require live updates.

• STDIO Mode:

  • The server (server.py) can also handle requests from a 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.

Both modes use the same server logic, ensuring consistent calculation behavior.

Installation & Usage

Prerequisites:

• Python 3.7 or higher

Installation:

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

Running the Project:

• Start the Server:

  python server.py
  

• Use STDIO Client:

  python client-stdio.py
  

  Enter expressions as prompted and receive results instantly.

• Use SSE Client:

  python client-sse.py
  

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