Graph Simulator

This repository contains the code used in TPSI lessons to simulate different graph behaviours

Get Started

Backend

The backend is created using typescript, Express.js and the WS package. The service is hosted on the Plesk platform of the school's servers at https://graphsimulator.barsanti.edu.it

Links for further informations about configurations:

• Configure Websockets on Plesk
• Use Node.js on Plesk

Frontend

The backend also serves a simple web page to inspect the network state providing the actions of all the users in realtime and also a visual representation of the network.

Java Client

The repository also contains a starter project to interact with the backend service.

Download the repository and setup the serverUrl string in the Main.java file to point to the school's backend.

Additional info in the Client README
