nodejs-vote-by-mac

Node.js voting system using the MAC address to identify voters.

This web app is meant to be run on a local network from a Linux machine, such as a Raspberry Pi. The MAC address of the client/voter is only available in this configuration because it uses the local ARP cache to resolve the MAC address from the IP.

Deploy

1. sudo chmod +x /etc/rc.local
2. Append

cd /home/pi/nodejs-vote-by-mac
/usr/bin/nodejs /home/pi/nodejs-vote-by-mac/server.js &

Usage

• Votes are cast by visiting the URL /NUMBER.
• A vote for 0 is used to delete the vote.
• Votes are stored in RAM and lost when the server is restarted.
• Configuration options are available in the file config.js.
