Ciao!

Ciao! allows people taking part in the same event to exchange contacts via QR code. It is a lightweight, no-nonsense web application.

Introduction

Before the event, you are to sign in with your credentials and print your badge. Make sure to pin it on your chest: as you meet new people, they might want to scan its QR code, or you could scan theirs. Either way, both your email addresses will be added to the other person's Ciao! contact list.

User setup

Ciao! is a Node.js web application which relies on Node Package Manager. Having both of them on your machine is required. While in this repository's root folder, you can install the needed dependencies using

npm i

After that, you can start your web server with

DOMAIN=$DOMAIN PORT=$PORT SECRET=$SECRET npm start

where $DOMAIN is the domain linking to your server, $PORT is the port used for connection, and $SECRET is used to sign the session ID cookies.
