fitbit-client-oauth2

Fitbit client

An OAuth 2.0 client to consume Fitbit's API.

Usage

Using an existing user token

var FitbitClient = require('fitbit-client-oauth2');

var client = new FitbitClient(<YOUR_FITBIT_API_KEY>, <YOUR_FITBIT_API_SECRET> );

// retrieve previously saved user's token from db
client.setTokens(access_token, refresh_token, expires_in);

client.getTimeSeries().then(function(res) {

    console.log('results: ', res);

}).catch(function(err) {
    console.log('error getting user data', err);
});

Refreshing an expired user token

    client.refreshAccessToken().then(function(token) {
    
        // save new token data to db
        // do more stuff here.
    
    }).catch(function(err) {
      console.log('error refreshing user token', err);
    });

TODO

• Implement full OAuth authorization code flow. (now it relays on passport-fitbit-oauth2).
• Cover more of the Fitbit API endpoints
• Add token expiration event to the client (EventEmitter).
• Implement automatic retries on token expiration errors

Other implementations

This package exists because Fitbit's newest endpoints works only with OAuth 2.0 and all other existing packages works only with OAuth 1.0. Some examples:

• fitbit-node
• fitbit-js
• node-fitbit
