Installation

This repository contains a Linux script for quickly starting this project. To use this script, the packages git, python3.10, and python-venv needs to be available from the command line. Then, the following commands can be used to start the server:

# Linux
apt-get install Python3.10 Python3.10-venv
git clone https://github.com/DHBW-FN-TIT20/EchoChat
cd EchoChat && ./start.sh

The EchoChat server can also be started manually with the following Python dependencies:

# Linux
pip3 install fastapi
pip3 install uvicorn
pip3 install websockets
pip3 install argparse

# Windows
pip install fastapi
pip install uvicorn
pip install websockets
pip install argparse

Alternatively, replace pip3/pip with python -m pip install [package]. Then, the server can be started by invoking uvicorn from the command line.

# Linux
cd EchoChat && uvicorn app:app

# Windows
cd EchoChat
uvicorn app:app

This should create a webserver available at http://127.0.0.1:8000. Additionally, the repo also contains a Python CLI available under ./app/client.py. Usage information is available by calling python client.py --help.
