Example Applications

// Generate an authorization URL
const authUrl = await client.devices.getAuthorizationUrl({
  provider: 'fitbit',
  redirectUri: 'https://your-app.com/callback'
});

// Redirect the user to authUrl to authorize your app

// Handle the callback
app.get('/callback', async (req, res) => {
  const { code } = req.query;

  // Exchange the code for an access token
  const user = await client.devices.completeAuthorization({
    code,
    redirectUri: 'https://your-app.com/callback'
  });

  // User is now connected
  console.log('Connected user:', user.id);
});

// Fetch activity data
const activityData = await client.users.getHealthData({
  userId: 'user_123',
  dataType: 'activity',
  startDate: '2023-01-01',
  endDate: '2023-01-31'
});

console.log('Activity data:', activityData);

// Fetch heart rate data
const heartRateData = await client.users.getHealthData({
  userId: 'user_123',
  dataType: 'heartRate',
  startDate: '2023-01-01',
  endDate: '2023-01-31'
});

console.log('Heart rate data:', heartRateData);

// Analyze sleep patterns
const sleepAnalysis = await client.ai.analyze({
  userId: 'user_123',
  dataType: 'sleep',
  startDate: '2023-01-01',
  endDate: '2023-01-31',
  analysisType: 'pattern'
});

console.log('Sleep analysis:', sleepAnalysis);

// Generate health predictions
const predictions = await client.ai.predict({
  userId: 'user_123',
  predictionType: 'diabetesRisk',
  timeframe: '6months'
});

console.log('Diabetes risk prediction:', predictions);
