aka diasim. Runs a discrete timestep simulation of diabetic metabolism.

• live modelling of insulin, exercise, and food metabolism.
  • exercise: can specify intensity and duration.
  • food: can specify carbs or protein, and glycemic index
  • insulin: models the nonlinear release curve of Fiasp.
• downloads glucose feed from NightScout.
• designed for use by insulin pump users
  • includes facilities to model basal/bolus parameters

$ npm i
$ npm run dev

# open http://localhost:3000

diasim is in development. You will need to download your NightScout glucose data to a local file in data/glucose.json. This can be automated using a script.

NIGHTSCOUT_ENDPOINT_URL=https://<NIGHTSCOUT_SERVER>.herokuapp.com ./scripts/get-data.sh

Then you can start adding events and simulating different changes to your parameters. Here's a sample of events you can paste and use (implemented in src/pages/helpers.ts):

20/5/2020 begin

# TIME food AMOUNT (carbs/protein) GLYCEMIC_INDEX
14.00 food 20g carbs 80
15.00 food 20g protein
16.00 insulin 12.1

# Bolus/correct uses the specified pump ratios.
16.00 bolus 50g
16.00 correct 12.5

# TIME exercise DURATION INTENSITY
17.00 exercise 30mins .8
