Glucoscape

Overview

Glucoscape is a small application that helps visualize Continuous Glucose Monitoring (CGM) data quickly and intuitively. It provides a heatmap representation of time spent below range, in range, and above range, allowing for easy identification of glucose patterns.

Features

• Loads the last 14 days of CGM data from your own Nightscout instance.
• Uses the target range you have configured in Nightscout.
• Displays a heatmap representation of time spent below/in/above your target range for each hour of each day.
• Visually summarises time in range for each day ("what was my total time in range yesterday?")
• Visually summarises time in range for each hour of day ("what's my average time in range between 9 and 10am?")

Getting Started

Prerequisite: Nightscout access

To provide access to your Nightscout data, you need to check three things:

1. Find your Nightscout instance address (URL).
2. Create an access token which Glucoscape will use as a password when talking to Nightscout.
   • You can create a token by going to your Nightscout menu > Admin Tools > Subjects - People, Devices > Add new Subject.
   • Set Name to whatever you like, e.g. glucoscape.
   • Set Roles to readable.
3. Make sure your Nightscout instance has CORS enabled.
   • Add cors to the list of enabled plug-ins.
   • See Nightscout docs for details.

Use the app directly on GitHub

This is the simplest way to use the app. It is pre-built and hosted directly by GitHub Pages.

1. Navigate to vitawasalreadytaken.github.io/glucoscape
2. Fill in your Nightscout address and access token and click Connect
3. ⭐️ Optionally bookmark the page for easier access next time (the address will look like https://vitawasalreadytaken.github.io/glucoscape/#session=%7B%22nightscoutUrl...)

Your Nightscout address and access token are never saved by the app. A simple way to keep them (and skip the Connect step next time) is to bookmark the page. Note that the address and access token will be a part of your bookmarked address.

Build and run the app yourself

1. Clone this repository
2. npm install
3. npm run build
4. Open build/index.html in your browser
5. Fill in your Nightscout address and access token and click Connect

I have also built Koboscout, an 'ambient' app showing a chart of your latest CGM readings on an e-reader device or tablet.
