garmin-connect

v1.6.0 refactor

TODO:

  • New HttpClient class
  • Login and get user token
  • Garmin URLs works with garmin.cn and garmin.com
  • Auto refresh Ouath2 token
  • Oauth1,Oauth2 token import and export.
  • Download Activity, countActivities, getActivities, getActivity, getUserProfile, getUserSettings
  • Upload Activity, delete Activity
  • Implementation of other methods, such as Badge,Workout,Gear etc
  • Handle MFA
  • Handle Account locked
  • Unit test
  • Listeners

If something is not working, please check https://connect.garmin.com/status/ first.

Currently, most of previous features are working, but some of Rest API are not added, such as Gear,Workout,Badge etc. So if you need these features, please add a PR.

All of above work inspired by https://github.com/matin/garth. Many thanks.

A powerful JavaScript library for connecting to Garmin Connect for sending and receiving health and workout data. It comes with some predefined methods to get and set different kinds of data for your Garmin account, but also have the possibility to make custom requests GET, POST and PUT are currently supported. This makes it easy to implement whatever may be missing to suite your needs.

Prerequisites

This library will require you to add a configuration file to your project root called garmin.config.json containing your username and password for the Garmin Connect service.

{
    "username": "my.email@example.com",
    "password": "MySecretPassword"
}

How to install

$ npm install garmin-connect

How to use

const { GarminConnect } = require('garmin-connect');
// Create a new Garmin Connect Client
const GCClient = new GarminConnect({
    username: 'my.email@example.com',
    password: 'MySecretPassword'
});
// Uses credentials from garmin.config.json or uses supplied params
await GCClient.login();
const userProfile = await GCClient.getUserProfile();

Now you can check userProfile.userName to verify that your login was successful.

Reusing your session(since v1.6.0)

Save token to file and reuse it.

GCClient.saveTokenToFile('/path/to/save/tokens');

Result:

$ ls /path/to/save/tokens
oauth1_token.json oauth2_token.json

Reuse token:

GCClient.loadTokenByFile('/path/to/save/tokens');

Or just save your token to db or other storage.

const oauth1 = GCClient.client.oauth1Token;
const oauth2 = GCClient.client.oauth2Token;
// save to db or other storage
...

Reuse token:

GCClient.loadToken(oauth1, oauth2);

Reusing your session(deprecated)

This is an experimental feature and might not yet provide full stability.

After a successful login the sessionJson getter and setter can be used to export and restore your session.

// Exporting the session
const session = GCClient.sessionJson;

// Use this instead of GCClient.login() to restore the session
// This will throw an error if the stored session cannot be reused
GCClient.restore(session);

The exported session should be serializable and can be stored as a JSON string.

A stored session can only be reused once and will need to be stored after each request. This can be done by attaching some storage to the sessionChange event.

GCClient.onSessionChange((session) => {
    /*
        Your choice of storage here
        node-persist will probably work in most cases 
     */
});

Login fallback

To make sure to use a stored session if possible, but fallback to regular login, one can use the restoreOrLogin method. The arguments username and password are both optional and the regular .login() will be called if session restore fails.

await GCClient.restoreOrLogin(session, username, password);

Events

  • sessionChange will trigger on a change in the current sessionJson

To attach a listener to an event, use the .on() method.

GCClient.on('sessionChange', (session) => console.log(session));

There's currently no way of removing listeners.

Uploads an activity file as a new Activity. The file can be a gpx, tcx, or fit file. If the activity already exists, the result will have a status code of 409. Upload fixed in 1.4.4, Garmin changed the upload api, the response detailedImportResult doesn't contain the new activityId.

const upload = await GCClient.uploadActivity('./some/path/to/file.fit');
// not working
const activityId = upload.detailedImportResult.successes[0].internalId;
const uploadId = upload.detailedImportResult.uploadId;

Upload activity image

Uploads an image to activity

Add workout

To add a custom workout, use the addWorkout or more specifically addRunningWorkout.

GCClient.addRunningWorkout('My 5k run', 5000, 'Some description');

Will add a running workout of 5km called 'My 5k run' and return a JSON object representing the saved workout.

Schedule workout

To add a workout to your calendar, first find your workout and then add it to a specific date.

const workouts = await GCClient.getWorkouts();
const id = workouts[0].workoutId;
GCClient.scheduleWorkout({ workoutId: id }, new Date('2020-03-24'));

This will add the workout to a specific date in your calendar and make it show up automatically if you're using any of the Garmin watches.

Delete workout

Deleting a workout is very similar to scheduling one.

const workouts = await GCClient.getWorkouts();
const id = workouts[0].workoutId;
GCClient.deleteWorkout({ workoutId: id });

Custom requests

This library will handle custom requests to your active Garmin Connect session. There are a lot of different url's that is used, which means that this library probably wont cover them all. By using the network analyze tool you can find url's that are used by Garmin Connect to fetch data.

Let's assume I found a GET requests to the following url:

https://connect.garmin.com/modern/proxy/wellness-service/wellness/dailyHeartRate/22f5f84c-de9d-4ad6-97f2-201097b3b983?date=2020-03-24

The request can be sent using GCClient by running

// You can get your displayName by using the getUserInfo method;
const displayName = '22f5f84c-de9d-4ad6-97f2-201097b3b983';
const url =
    'https://connect.garmin.com/modern/proxy/wellness-service/wellness/dailyHeartRate/';
const dateString = '2020-03-24';
GCClient.get(url + displayName, { date: dateString });

and will net you the same result as using the provided way

GCClient.getHeartRate();

Notice how the client will keep track of the url's, your user information as well as keeping the session alive.

Limitations

Many responses from Garmin Connect are missing type definitions and defaults to unknown. Feel free to add types by opening a pull request.

For now, this library only supports the following:

  • Get user info
  • Get social user info
  • Get heart rate
  • Set body weight
  • Get list of workouts
  • Add new workouts
  • Add workouts to you calendar
  • Remove previously added workouts
  • Get list of activities
  • Get details about one specific activity
  • Get the step count
  • Get earned badges
  • Get available badges
  • Get details about one specific badge
