Currently a read only implementation for reading data from the Fitbit API as an authenticated user.
### TODO
I've split this into two sections, top section is what I need to have for the project I created this module for and the latter is what the API supports.
Needed by me:
- Add user model
- Add time series data for models
- Allow data models to be updated("logged") and deleted via the API
Supported by API:
- Add Blood pressure, heart rate, glucose resource models
- Add goals for all models that support them
- Collection metadata models
- Anything else...
npm install fitbit
Below is an example usage for authenticating and making a resource request:
var express = require('express')
, config = require('./config/app')
, app = express()
, Fitbit = require('fitbit');
app.use(express.cookieParser());
app.use(express.session({secret: 'hekdhthigib'}));
app.listen(3000);
// OAuth flow
app.get('/', function (req, res) {
// Create an API client and start authentication via OAuth
var client = new Fitbit(config.CONSUMER_KEY, config.CONSUMER_SECRET);
client.getRequestToken(function (err, token, tokenSecret) {
if (err) {
// Take action
return;
}
req.session.oauth = {
requestToken: token
, requestTokenSecret: tokenSecret
};
res.redirect(client.authorizeUrl(token));
});
});
// On return from the authorization
app.get('/oauth_callback', function (req, res) {
var verifier = req.query.oauth_verifier
, oauthSettings = req.session.oauth
, client = new Fitbit(config.CONSUMER_KEY, config.CONSUMER_SECRET);
// Request an access token
client.getAccessToken(
oauthSettings.requestToken
, oauthSettings.requestTokenSecret
, verifier
, function (err, token, secret) {
if (err) {
// Take action
return;
}
oauthSettings.accessToken = token;
oauthSettings.accessTokenSecret = secret;
res.redirect('/stats');
}
);
});
// Display some stats
app.get('/stats', function (req, res) {
client = new Fitbit(
config.CONSUMER_KEY
, config.CONSUMER_SECRET
, { // Now set with access tokens
accessToken: req.session.oauth.accessToken
, accessTokenSecret: req.session.oauth.accessTokenSecret
, unitMeasure: 'en_GB'
}
);
// Fetch todays activities
client.getActivities(function (err, activities) {
if (err) {
// Take action
return;
}
// `activities` is a Resource model
res.send('Total steps today: ' + activities.steps());
});
});
