cgm.js

A JavaScript port of pydexcom

Requirements

This has been tested from Node 14 to Node 18, but may work in earlier versions as well.

Usage

$3

``js
const Dexcom = require("cgm.js");
`

For ESM, set "type": "module", in your package.json.

`js
import Dexcom from "cgm.js";
`

$3

Most recent reading:

`js
const dexcom = new Dexcom("user", "pass");
const latestGlucoseReading = await dexcom.getLatestGlucoseReading();
`

getCurrentGlucoseReading() should return the same result but is maintained for parity with the original package.

$3

`js
GlucoseReading {
value: 143,
mgdL: 143,
mmolL: 7.9,
trend: 4,
trendDescription: 'steady',
trendArrow: '→',
time: 2023-02-26T00:48:54.000Z,
json: { WT: 'Date(1677372534000)', Value: 143, Trend: 'Flat' }
}
`

$3

`js
const dexcom = new Dexcom("user", "pass");
const glucoseReadings = await dexcom.getGlucoseReadings(15, 3); // minutes and number of readings readings
`

The service will return the minimum of the two parameters (minutes and maxCount of readings), so if your readings take place every five minutes and you request 30 minutes and 3 readings, you will only see three readings returned.
