What is the Peer++ system?

The peer++ evaluation system ensures quality evaluations by matching students with high-level evaluators.

Installation

Convert ./config/env-example to .env and fill in the secret data.

By default port 8080 is used for the webhooks express server and port 3000 is used for the slack bot using the slackbot API.

The slackbot runs over Websockets instead of HTTP Requests.

Development

1. Install NodeJS 18.x or higher.
2. Install dependencies: npm install
3. Use npm run dev for development mode.

Production

In production environments, use Docker.

• Use make up to run in a docker container.
• Use make down to shut down the docker container.

Or, if you're confident in your Docker skills, you can just use the docker compose command directly.

Logrotate

In production, we recommend setting up a logrotate in the logs directory. Create a logrotate config in the /etc/logrotate.d folder.

You can use or modify the configuration below:

/root/peer-bot/logs/log.txt {
        weekly
        missingok
        rotate 4
        compress
        delaycompress
        shred
        ifempty
        create 644 root root
}

Useful how-tos

Add a user to the peer++ group

1. Go to the peer-bot directory.
2. Run node src/scripts/manageUser.js add <login> where <login> is the login of the user you want to add to the peer++ group.

Remove a user from the peer++ group

1. Go to the peer-bot directory.
2. Run node src/scripts/manageUser.js remove <login> where <login> is the login of the user you want to remove from the peer++ group.

List all users in the peer++ group

1. Go to the peer-bot directory.
2. Run node src/scripts/getUsers.js.

Manually schedule a peer++ evaluation

1. Go to the peer-bot directory.
2. Run node src/scripts/bookEval.js <scaleID> <teamID> <userID> where <scaleID> is the scaleID of the scale you want to use for the evaluation, <teamID> is the teamID of the team you want to schedule an evaluation for and <userID> is the userID of the evaluator (the one evaluating the team).

Allow cancellation of a peer++ evaluation

1. Go to the peer-bot directory.
2. Run sqlite3 db/peerdb.sqlite.
3. Run INSERT INTO expiredTeam(teamID) VALUES ('<teamID>'); in the sqlite3 shell, where <teamID> is the teamID of the team you want to cancel the evaluation for.
4. Run .exit to exit the sqlite3 shell.
5. Tell the team that they can now cancel the evaluation (make them press x next to the evaluation on the Intranet).
6. Run node src/scripts/addPoint.js <login> where <login> is the login of the student who lost an evaluation point for the cancellation. This will refund the point to the student.
