Levels Health (unofficial)
Unofficial JS API for Levels Health, mined using Charles proxy.
This API is not associated with Levels Health and you shouldn't bother them if this breaks due to their own API changes.
Installation
npm install --save levels-health-unofficial
yarn install levels-health-unofficial
Usage
const LevelsHealth = require('levels-health-unofficial')
// Class was used to hold `token` and constructors can't be async`
const levels = new LevelsHealth()
const email = 'email@email.com'
const password = 'hunter2!'
// No need to save this, just useful if you want it. Their login method is AWS Cognito so
// this method could be handy utility when the API is expanded and this lib isn't update.
const jwtToken = await levels.login(email, password)
const beginQuery = dayjs().subtract(7, 'days').startOf()
const endQuery = dayjs.add(1, 'days').startOf()
const glucoseHistory = await levels.glucoseHistory(beginQuery, endQuery)
const {
glucoseMetrics,
} = glucoseHistory
glucoseMetrics.values.forEach(console.log)
