Overview

A Team Huddle site where teams can submit metrics ready for a Daily Huddle discussion.
Built with HTML, Javascript, Node.js, Express.
Data is written to a PostgreSQL database.

Features

• Users can select their user and a date then enter their metrics for that day.
• Data is pulled from the PostgreSQL when a user changes the user or date in the form.
• The Huddle host can navigate through the user list using the arrows in the form or with the keyboard left and right arrow keys.
• If a users capacity is greater than 3 or their wellbeing is 30 minutes or less, those metrics will appear as red and bold so the Huddle host can easily spot them.
• There are multiple API endpoints for adding/removing users, and collecting metrics.
