path := fmt.Sprintf("/metrics-service/metrics/trainingStatus/%s", dateStr)
data, err := client.ConnectAPI(path, "GET", nil, nil)
if err != nil {
return nil, fmt.Errorf("failed to get training status: %w", err)
}
if len(data) == 0 {
return nil, nil
}
var result TrainingStatus
if err := json.Unmarshal(data, &result); err != nil {
return nil, fmt.Errorf("failed to parse training status: %w", err)
}
return &result, nil
}
func NewTrainingLoad() *TrainingLoad {
tl := &TrainingLoad{}
tl.GetFunc = tl.get
return tl
}
func (t *TrainingLoad) get(day time.Time, client *client.Client) (interface{}, error) {
dateStr := day.Format("2006-01-02")
endDate := day.AddDate(0, 0, 6).Format("2006-01-02") // Get week of data
path := fmt.Sprintf("/metrics-service/metrics/trainingLoad/%s/%s", dateStr, endDate)
data, err := client.ConnectAPI(path, "GET", nil, nil)
if err != nil {
return nil, fmt.Errorf("failed to get training load: %w", err)
}
if len(data) == 0 {
return nil, nil
}
var results []TrainingLoad
if err := json.Unmarshal(data, &results); err != nil {
return nil, fmt.Errorf("failed to parse training load: %w", err)
}
if len(results) == 0 {
return nil, nil
}
return &results[0], nil
}
```
## 5. Client Methods Integration
#### Add these methods to `internal/api/client/client.go`:
```go
// GetTrainingStatus retrieves current training status
func (c *Client) GetTrainingStatus(date time.Time) (*types.TrainingStatus, error) {
trainingStatus := data.NewTrainingStatus()
result, err := trainingStatus.Get(date, c)
if err != nil {
return nil, err
}
if result == nil {
return nil, nil
}
status, ok := result.(*types.TrainingStatus)
if !ok {
return nil, fmt.Errorf("unexpected training status type")
}
return status, nil
}
// GetTrainingLoad retrieves training load data
func (c *Client) GetTrainingLoad(date time.Time) (*types.TrainingLoad, error) {
trainingLoad := data.NewTrainingLoad()
result, err := trainingLoad.Get(date, c)
if err != nil {
return nil, err
}
if result == nil {
return nil, nil
}
load, ok := result.(*types.TrainingLoad)
if !ok {
return nil, fmt.Errorf("unexpected training load type")
}
return load, nil
}
// GetFitnessAge retrieves fitness age calculation
func (c *Client) GetFitnessAge() (*types.FitnessAge, error) {
path := "/fitness-service/fitness/fitnessAge"
data, err := c.ConnectAPI(path, "GET", nil, nil)
if err != nil {
return nil, fmt.Errorf("failed to get fitness age: %w", err)
}
if len(data) == 0 {
return nil, nil
}
var fitnessAge types.FitnessAge
if err := json.Unmarshal(data, &fitnessAge); err != nil {
return nil, fmt.Errorf("failed to parse fitness age: %w", err)
}
fitnessAge.LastUpdated = time.Now()
return &fitnessAge, nil
}
```
## Implementation Steps
### Phase 1: Sleep Data (Week 1)
1. Create `internal/data/sleep_detailed.go`
2. Update `internal/types/garmin.go` with sleep types
3. Add client methods
4. Create tests
5. Test with real data
### Phase 2: HRV Enhancement (Week 2)
1. Update existing `internal/data/hrv.go`
2. Add new HRV types to types file
3. Enhance client methods
4. Create comprehensive tests
### Phase 3: Body Battery Details (Week 3)
1. Update `internal/data/body_battery.go`
2. Add event tracking
3. Add convenience methods
4. Create tests
### Phase 4: Training Metrics (Week 4)
1. Create `internal/data/training.go`
2. Add training types
3. Implement client methods
4. Create tests and validation
## Testing Strategy
Create test files for each new data type:
```go
// Example test structure
func TestDetailedSleepData_Get(t *testing.T) {
// Mock response from API
mockResponse := `{
"dailySleepDTO": {
"userProfilePk": 12345,
"calendarDate": "2023-06-15",
"deepSleepSeconds": 7200,
"lightSleepSeconds": 14400,
"remSleepSeconds": 3600,
"awakeSleepSeconds": 1800
},
"sleepMovement": [],
"sleepLevels": []
}`
// Create mock client
server := testutils.MockJSONResponse(http.StatusOK, mockResponse)
defer server.Close()
// Test implementation
// ... test logic
}
```
## Error Handling Patterns
For each endpoint, implement consistent error handling:
```go
func (d *DataType) get(day time.Time, client *client.Client) (interface{}, error) {
data, err := client.ConnectAPI(path, "GET", nil, nil)
if err != nil {
// Log the error but don't fail completely
fmt.Printf("Warning: Failed to get %s data: %v\n", "datatype", err)
return nil, nil // Return nil data, not error for missing data
}
if len(data) == 0 {
return nil, nil // No data available
}
// Parse and validate
var result DataType
if err := json.Unmarshal(data, &result); err != nil {
return nil, fmt.Errorf("failed to parse %s data: %w", "datatype", err)
}
return &result, nil
}
```
## Usage Examples
After implementation, users can access the data like this:
```go
// Get detailed sleep data
sleepData, err := client.GetDetailedSleepData(time.Now().AddDate(0, 0, -1))
if err != nil {
log.Fatal(err)
}
if sleepData != nil {
fmt.Printf("Sleep efficiency: %.1f%%\n", sleepData.GetSleepEfficiency())
fmt.Printf("Total sleep: %.1f hours\n", sleepData.GetTotalSleepTime())
}
// Get training status
status, err := client.GetTrainingStatus(time.Now())
if err != nil {
log.Fatal(err)
}
if status != nil {
fmt.Printf("Training Status: %s\n", status.TrainingStatusKey)
fmt.Printf("Load Ratio: %.2f\n", status.LoadRatio)
}
```
This implementation guide provides a comprehensive foundation for adding the most requested Garmin Connect API endpoints to your Go client.

# Implementation Plan for Steps 1 & 2: Project Structure and Client Refactoring
## Overview
This document provides a detailed implementation plan for refactoring the existing Go code from `main.go` into a proper modular structure as outlined in the porting plan.
## Current State Analysis
### Existing Code in main.go (Lines 1-761)
The current `main.go` contains:
- **Client struct** (lines 24-30) with domain, httpClient, username, authToken
- **Data models**: SessionData, ActivityType, EventType, Activity, OAuth1Token, OAuth2Token, OAuthConsumer
- **OAuth functions**: loadOAuthConsumer, generateNonce, generateTimestamp, percentEncode, createSignatureBaseString, createSigningKey, signRequest, createOAuth1AuthorizationHeader
- **SSO functions**: getCSRFToken, extractTicket, exchangeOAuth1ForOAuth2, Login, loadEnvCredentials
- **Client methods**: NewClient, getUserProfile, GetActivities, SaveSession, LoadSession
- **Main function** with authentication flow and activity retrieval
## Step 1: Project Structure Setup
### Directory Structure to Create
```
garmin-connect/
├── client/
│ ├── client.go # Core client logic
│ ├── auth.go # Authentication handling
│ └── sso.go # SSO authentication
├── data/
│ └── base.go # Base data models and interfaces
├── types/
│ └── tokens.go # Token structures
├── utils/
│ └── utils.go # Utility functions
├── errors/
│ └── errors.go # Custom error types
├── cmd/
│ └── garth/
│ └── main.go # CLI tool (refactored from current main.go)
└── main.go # Keep original temporarily for testing
```
## Step 2: Core Client Refactoring - Detailed Implementation
### 2.1 Create `types/tokens.go`
**Purpose**: Centralize all token-related structures
```go
package types
import "time"
// OAuth1Token represents OAuth1 token response
type OAuth1Token struct {
OAuthToken string `json:"oauth_token"`
OAuthTokenSecret string `json:"oauth_token_secret"`
MFAToken string `json:"mfa_token,omitempty"`
Domain string `json:"domain"`
}
// OAuth2Token represents OAuth2 token response
type OAuth2Token struct {
AccessToken string `json:"access_token"`
TokenType string `json:"token_type"`
ExpiresIn int `json:"expires_in"`
RefreshToken string `json:"refresh_token"`
Scope string `json:"scope"`
CreatedAt time.Time // Added for expiration tracking
}
// OAuthConsumer represents OAuth consumer credentials
type OAuthConsumer struct {
ConsumerKey string `json:"consumer_key"`
ConsumerSecret string `json:"consumer_secret"`
}
// SessionData represents saved session information
type SessionData struct {
Domain string `json:"domain"`
Username string `json:"username"`
AuthToken string `json:"auth_token"`
}
```
### 2.2 Create `client/client.go`
**Purpose**: Core client functionality and HTTP operations
```go
package client
import (
"crypto/hmac"
"crypto/rand"
"crypto/sha1"
"encoding/base64"
"encoding/json"
"fmt"
"io"
"net/http"
"net/http/cookiejar"
"net/url"
"os"
"regexp"
"sort"
"strconv"
"strings"
"time"
"github.com/joho/godotenv"
"garmin-connect/types"
)
// Client represents the Garmin Connect client
type Client struct {
domain string
httpClient *http.Client
username string
authToken string
oauth1Token *types.OAuth1Token
oauth2Token *types.OAuth2Token
}
// ConfigOption represents a client configuration option
type ConfigOption func(*Client)
// NewClient creates a new Garmin Connect client
func NewClient(domain string) (*Client, error) {
jar, err := cookiejar.New(nil)
if err != nil {
return nil, fmt.Errorf("failed to create cookie jar: %w", err)
}
return &Client{
domain: domain,
httpClient: &http.Client{
Jar: jar,
Timeout: 30 * time.Second,
},
}, nil
}
// Configure applies configuration options to the client
func (c *Client) Configure(opts ...ConfigOption) error {
for _, opt := range opts {
opt(c)
}
return nil
}
// ConnectAPI makes authenticated API calls to Garmin Connect
func (c *Client) ConnectAPI(path, method string, data interface{}) (interface{}, error) {
// Implementation based on Python http.py Client.connectapi()
// Should handle authentication, retries, and error responses
}
// Download downloads data from Garmin Connect
func (c *Client) Download(path string) ([]byte, error) {
// Implementation for downloading files/data
}
// Upload uploads data to Garmin Connect
func (c *Client) Upload(filePath, uploadPath string) (map[string]interface{}, error) {
// Implementation for uploading files/data
}
// GetUserProfile retrieves the current user's profile
func (c *Client) GetUserProfile() error {
// Extracted from main.go getUserProfile method
}
// GetActivities retrieves recent activities
func (c *Client) GetActivities(limit int) ([]Activity, error) {
// Extracted from main.go GetActivities method
}
// SaveSession saves the current session to a file
func (c *Client) SaveSession(filename string) error {
// Extracted from main.go SaveSession method
}
// LoadSession loads a session from a file
func (c *Client) LoadSession(filename string) error {
// Extracted from main.go LoadSession method
}
```
### 2.3 Create `client/auth.go`
**Purpose**: Authentication and token management
```go
package client
import (
"crypto/hmac"
"crypto/rand"
"crypto/sha1"
"encoding/base64"
"encoding/json"
"fmt"
"net/http"
"net/url"
"sort"
"strconv"
"strings"
"time"
"garmin-connect/types"
)
var oauthConsumer *types.OAuthConsumer
// loadOAuthConsumer loads OAuth consumer credentials
func loadOAuthConsumer() (*types.OAuthConsumer, error) {
// Extracted from main.go loadOAuthConsumer function
}
// OAuth1 signing functions (extract from main.go)
func generateNonce() string
func generateTimestamp() string
func percentEncode(s string) string
func createSignatureBaseString(method, baseURL string, params map[string]string) string
func createSigningKey(consumerSecret, tokenSecret string) string
func signRequest(consumerSecret, tokenSecret, baseString string) string
func createOAuth1AuthorizationHeader(method, requestURL string, params map[string]string, consumerKey, consumerSecret, token, tokenSecret string) string
// Token expiration checking
func (t *types.OAuth2Token) IsExpired() bool {
return time.Since(t.CreatedAt) > time.Duration(t.ExpiresIn)*time.Second
}
// MFA support placeholder
func (c *Client) HandleMFA(mfaToken string) error {
// Placeholder for MFA handling
return fmt.Errorf("MFA not yet implemented")
}
```
### 2.4 Create `client/sso.go`
**Purpose**: SSO authentication flow
```go
package client
import (
"encoding/json"
"fmt"
"io"
"net/http"
"net/url"
"os"
"regexp"
"strings"
"github.com/joho/godotenv"
"garmin-connect/types"
)
var (
csrfRegex = regexp.MustCompile(`name="_csrf"\s+value="(.+?)"`)
titleRegex = regexp.MustCompile(`<title>(.+?)</title>`)
ticketRegex = regexp.MustCompile(`embed\?ticket=([^"]+)"`)
)
// Login performs SSO login with email and password
func (c *Client) Login(email, password string) error {
// Extracted from main.go Login method
}
// ResumeLogin resumes login after MFA
func (c *Client) ResumeLogin(mfaToken string) error {
// New method for MFA completion
}
// SSO helper functions (extract from main.go)
func getCSRFToken(respBody string) string
func extractTicket(respBody string) string
func exchangeOAuth1ForOAuth2(oauth1Token *types.OAuth1Token, domain string) (*types.OAuth2Token, error)
func loadEnvCredentials() (email, password, domain string, err error)
```
### 2.5 Create `data/base.go`
**Purpose**: Base data models and interfaces
```go
package data
import (
"time"
"garmin-connect/client"
)
// ActivityType represents the type of activity
type ActivityType struct {
TypeID int `json:"typeId"`
TypeKey string `json:"typeKey"`
ParentTypeID *int `json:"parentTypeId,omitempty"`
}
// EventType represents the event type of an activity
type EventType struct {
TypeID int `json:"typeId"`
TypeKey string `json:"typeKey"`
}
// Activity represents a Garmin Connect activity
type Activity struct {
ActivityID int64 `json:"activityId"`
ActivityName string `json:"activityName"`
Description string `json:"description"`
StartTimeLocal string `json:"startTimeLocal"`
StartTimeGMT string `json:"startTimeGMT"`
ActivityType ActivityType `json:"activityType"`
EventType EventType `json:"eventType"`
Distance float64 `json:"distance"`
Duration float64 `json:"duration"`
ElapsedDuration float64 `json:"elapsedDuration"`
MovingDuration float64 `json:"movingDuration"`
ElevationGain float64 `json:"elevationGain"`
ElevationLoss float64 `json:"elevationLoss"`
AverageSpeed float64 `json:"averageSpeed"`
MaxSpeed float64 `json:"maxSpeed"`
Calories float64 `json:"calories"`
AverageHR float64 `json:"averageHR"`
MaxHR float64 `json:"maxHR"`
}
// Data interface for all data models
type Data interface {
Get(day time.Time, client *client.Client) (interface{}, error)
List(end time.Time, days int, client *client.Client, maxWorkers int) ([]interface{}, error)
}
```
### 2.6 Create `errors/errors.go`
**Purpose**: Custom error types for better error handling
```go
package errors
import "fmt"
// GarthError represents a general Garth error
type GarthError struct {
Message string
Cause error
}
func (e *GarthError) Error() string {
if e.Cause != nil {
return fmt.Sprintf("%s: %v", e.Message, e.Cause)
}
return e.Message
}
// GarthHTTPError represents an HTTP-related error
type GarthHTTPError struct {
GarthError
StatusCode int
Response string
}
func (e *GarthHTTPError) Error() string {
return fmt.Sprintf("HTTP %d: %s", e.StatusCode, e.GarthError.Error())
}
```
### 2.7 Create `utils/utils.go`
**Purpose**: Utility functions
```go
package utils
import (
"strings"
"time"
"unicode"
)
// CamelToSnake converts CamelCase to snake_case
func CamelToSnake(s string) string {
var result []rune
for i, r := range s {
if unicode.IsUpper(r) && i > 0 {
result = append(result, '_')
}
result = append(result, unicode.ToLower(r))
}
return string(result)
}
// CamelToSnakeDict converts map keys from camelCase to snake_case
func CamelToSnakeDict(m map[string]interface{}) map[string]interface{} {
result := make(map[string]interface{})
for k, v := range m {
result[CamelToSnake(k)] = v
}
return result
}
// FormatEndDate formats an end date interface to time.Time
func FormatEndDate(end interface{}) time.Time {
switch v := end.(type) {
case time.Time:
return v
case string:
if t, err := time.Parse("2006-01-02", v); err == nil {
return t
}
}
return time.Now()
}
// DateRange generates a range of dates
func DateRange(end time.Time, days int) []time.Time {
var dates []time.Time
for i := 0; i < days; i++ {
dates = append(dates, end.AddDate(0, 0, -i))
}
return dates
}
// GetLocalizedDateTime converts timestamps to localized time
func GetLocalizedDateTime(gmtTimestamp, localTimestamp int64) time.Time {
// Implementation based on timezone offset
return time.Unix(localTimestamp, 0)
}
```
### 2.8 Refactor `main.go`
**Purpose**: Simplified main function using the new client package
```go
package main
import (
"fmt"
"log"
"os"
"garmin-connect/client"
"garmin-connect/data"
)
func main() {
// Load credentials from .env file
email, password, domain, err := loadEnvCredentials()
if err != nil {
log.Fatalf("Failed to load credentials: %v", err)
}
// Create client
garminClient, err := client.NewClient(domain)
if err != nil {
log.Fatalf("Failed to create client: %v", err)
}
// Try to load existing session first
sessionFile := "garmin_session.json"
if err := garminClient.LoadSession(sessionFile); err != nil {
fmt.Println("No existing session found, logging in with credentials from .env...")
if err := garminClient.Login(email, password); err != nil {
log.Fatalf("Login failed: %v", err)
}
// Save session for future use
if err := garminClient.SaveSession(sessionFile); err != nil {
fmt.Printf("Failed to save session: %v\n", err)
}
} else {
fmt.Println("Loaded existing session")
}
// Test getting activities
activities, err := garminClient.GetActivities(5)
if err != nil {
log.Fatalf("Failed to get activities: %v", err)
}
// Display activities
displayActivities(activities)
}
func displayActivities(activities []data.Activity) {
fmt.Printf("\n=== Recent Activities ===\n")
for i, activity := range activities {
fmt.Printf("%d. %s\n", i+1, activity.ActivityName)
fmt.Printf(" Type: %s\n", activity.ActivityType.TypeKey)
fmt.Printf(" Date: %s\n", activity.StartTimeLocal)
if activity.Distance > 0 {
fmt.Printf(" Distance: %.2f km\n", activity.Distance/1000)
}
if activity.Duration > 0 {
duration := time.Duration(activity.Duration) * time.Second
fmt.Printf(" Duration: %v\n", duration.Round(time.Second))
}
fmt.Println()
}
}
func loadEnvCredentials() (email, password, domain string, err error) {
// This function should be moved to client package eventually
// For now, keep it here to maintain functionality
if err := godotenv.Load(); err != nil {
return "", "", "", fmt.Errorf("failed to load .env file: %w", err)
}
email = os.Getenv("GARMIN_EMAIL")
password = os.Getenv("GARMIN_PASSWORD")
domain = os.Getenv("GARMIN_DOMAIN")
if domain == "" {
domain = "garmin.com"
}
if email == "" || password == "" {
return "", "", "", fmt.Errorf("GARMIN_EMAIL and GARMIN_PASSWORD must be set in .env file")
}
return email, password, domain, nil
}
```
## Implementation Order
1. **Create directory structure** first
2. **Create types/tokens.go** - Move all token structures
3. **Create errors/errors.go** - Define custom error types
4. **Create utils/utils.go** - Add utility functions
5. **Create client/auth.go** - Extract authentication logic
6. **Create client/sso.go** - Extract SSO logic
7. **Create data/base.go** - Extract data models
8. **Create client/client.go** - Extract client logic
9. **Refactor main.go** - Update to use new packages
10. **Test the refactored code** - Ensure functionality is preserved
## Testing Strategy
After each major step:
1. Run `go build` to check for compilation errors
2. Test authentication flow if SSO logic was modified
3. Test activity retrieval if client methods were changed
4. Verify session save/load functionality
## Key Considerations
1. **Maintain backward compatibility** - Ensure existing functionality works
2. **Error handling** - Use new custom error types appropriately
3. **Package imports** - Update import paths correctly
4. **Visibility** - Export only necessary functions/types (capitalize appropriately)
5. **Documentation** - Add package and function documentation
This plan provides a systematic approach to refactoring the existing code while maintaining functionality and preparing for the addition of new features from the Python library.

**File:** `garth/data/base.go`
Update the List method to properly use the BaseData pattern:
```go
func (b *BaseData) List(end time.Time, days int, c *client.Client, maxWorkers int) ([]interface{}, []error) {
if maxWorkers < 1 {
maxWorkers = 10 // Match Python's MAX_WORKERS
}
dates := utils.DateRange(end, days)
var wg sync.WaitGroup
workCh := make(chan time.Time, days)
resultsCh := make(chan result, days)
type result struct {
data interface{}
err error
}
// Worker function
worker := func() {
defer wg.Done()
for date := range workCh {
data, err := b.Get(date, c)
resultsCh <- result{data: data, err: err}
}
}
// Start workers
wg.Add(maxWorkers)
for i := 0; i < maxWorkers; i++ {
go worker()
}
// Send work
go func() {
for _, date := range dates {
workCh <- date
}
close(workCh)
}()
// Close results channel when workers are done
go func() {
wg.Wait()
close(resultsCh)
}()
var results []interface{}
var errs []error
for r := range resultsCh {
if r.err != nil {
errs = append(errs, r.err)
} else if r.data != nil {
results = append(results, r.data)
}
}
return results, errs
}
```
## Phase 5: Testing and Documentation (Week 3)
### Task 5.1: Create Integration Tests
**File:** `garth/integration_test.go` (new file)
```go
package garth_test
import (
"testing"
"time"
"garmin-connect/garth/client"
"garmin-connect/garth/data"
)
func TestBodyBatteryIntegration(t *testing.T) {
if testing.Short() {
t.Skip("Skipping integration test in short mode")
}
c, err := client.NewClient("garmin.com")
require.NoError(t, err)
// Load test session
err = c.LoadSession("test_session.json")
if err != nil {
t.Skip("No test session available")
}
bb := &data.DailyBodyBatteryStress{}
result, err := bb.Get(time.Now().AddDate(0, 0, -1), c)
assert.NoError(t, err)
if result != nil {
bbData := result.(*data.DailyBodyBatteryStress)
assert.NotZero(t, bbData.UserProfilePK)
}
}
```
### Task 5.2: Update Package Exports
**File:** `garth/__init__.go` (new file)
Create a package-level API that matches Python's `__init__.py`:
```go
package garth
import (
"garmin-connect/garth/client"
"garmin-connect/garth/data"
"garmin-connect/garth/stats"
)
// Re-export main types for convenience
type Client = client.Client
// Data types
type BodyBatteryData = data.DailyBodyBatteryStress
type HRVData = data.HRVData
type SleepData = data.DailySleepDTO
type WeightData = data.WeightData
// Stats types
type DailySteps = stats.DailySteps
type DailyStress = stats.DailyStress
type DailyHRV = stats.DailyHRV
// Main functions
var (
NewClient = client.NewClient
Login = client.Login
)
```
## Implementation Checklist
### Week 1 (Core Implementation):
- [ ] Client.ConnectAPI method
- [ ] Download/Upload methods
- [ ] Body Battery Get() implementation
- [ ] Sleep Data Get() implementation
- [ ] End-to-end test with real API
### Week 2 (Complete Feature Set):
- [ ] HRV and Weight Get() implementations
- [ ] Complete stats module (all 7 types)
- [ ] BaseData List() method fix
- [ ] Integration tests
### Week 3 (Polish and Documentation):
- [ ] Package-level exports
- [ ] README with examples
- [ ] Performance testing vs Python
- [ ] CLI tool verification
## Key Implementation Notes
1. **Error Handling**: Use the existing comprehensive error types
2. **Date Formats**: Always use `time.Time` and convert to "2006-01-02" for API calls
3. **Response Parsing**: Always use `utils.CamelToSnakeDict` before unmarshaling
4. **Concurrency**: The existing BaseData.List() handles worker pools correctly
5. **Testing**: Use `testutils.MockJSONResponse` for unit tests
## Success Criteria
Port is complete when:
- All Python data models have working Get() methods
- All Python stats types are implemented
- CLI tool outputs same format as Python
- Integration tests pass against real API
- Performance is equal or better than Python
**Estimated Effort:** 2-3 weeks for junior developer with this detailed plan.

# VO2 Max Implementation Guide
## Overview
This guide will help you implement VO2 max data retrieval in the go-garth Garmin Connect API client. VO2 max is a fitness metric that represents the maximum amount of oxygen consumption during exercise.
## Background
Based on analysis of existing Garmin Connect libraries:
- **Python garth**: Retrieves VO2 max via `UserSettings.get().user_data.vo_2_max_running/cycling`
- **Go garmin-connect**: Retrieves via `PersonalInformation().BiometricProfile.VO2Max/VO2MaxCycling`
Our implementation will follow the Python approach since we already have a `UserSettings` structure.
## Files to Modify
### 1. Update `internal/types/garmin.go`
**What to do**: Add enhanced VO2 max types to support comprehensive VO2 max data.
**Location**: Add these structs to the file (around line 120, after the existing `VO2MaxData` struct):
```go
// Replace the existing VO2MaxData struct with this enhanced version
type VO2MaxData struct {
Date time.Time `json:"calendarDate"`
VO2MaxRunning *float64 `json:"vo2MaxRunning"`
VO2MaxCycling *float64 `json:"vo2MaxCycling"`
UserProfilePK int `json:"userProfilePk"`
}
// Add these new structs
type VO2MaxEntry struct {
Value float64 `json:"value"`
ActivityType string `json:"activityType"` // "running" or "cycling"
Date time.Time `json:"date"`
Source string `json:"source"` // "user_settings", "activity", etc.
}
type VO2MaxProfile struct {
UserProfilePK int `json:"userProfilePk"`
Running *VO2MaxEntry `json:"running"`
Cycling *VO2MaxEntry `json:"cycling"`
History []VO2MaxEntry `json:"history,omitempty"`
LastUpdated time.Time `json:"lastUpdated"`
}
```
### 2. Create `internal/data/vo2max.go`
**What to do**: Create a new file to handle VO2 max data retrieval.
**Create new file** with this content:
```go
package data
import (
"encoding/json"
"fmt"
"time"
"go-garth/internal/api/client"
"go-garth/internal/types"
)
// VO2MaxData implements the Data interface for VO2 max retrieval
type VO2MaxData struct {
BaseData
}
// NewVO2MaxData creates a new VO2MaxData instance
func NewVO2MaxData() *VO2MaxData {
vo2 := &VO2MaxData{}
vo2.GetFunc = vo2.get
return vo2
}
// get implements the specific VO2 max data retrieval logic
func (v *VO2MaxData) get(day time.Time, c *client.Client) (interface{}, error) {
// Primary approach: Get from user settings (most reliable)
settings, err := c.GetUserSettings()
if err != nil {
return nil, fmt.Errorf("failed to get user settings: %w", err)
}
// Extract VO2 max data from user settings
vo2Profile := &types.VO2MaxProfile{
UserProfilePK: settings.ID,
LastUpdated: time.Now(),
}
// Add running VO2 max if available
if settings.UserData.VO2MaxRunning != nil && *settings.UserData.VO2MaxRunning > 0 {
vo2Profile.Running = &types.VO2MaxEntry{
Value: *settings.UserData.VO2MaxRunning,
ActivityType: "running",
Date: day,
Source: "user_settings",
}
}
// Add cycling VO2 max if available
if settings.UserData.VO2MaxCycling != nil && *settings.UserData.VO2MaxCycling > 0 {
vo2Profile.Cycling = &types.VO2MaxEntry{
Value: *settings.UserData.VO2MaxCycling,
ActivityType: "cycling",
Date: day,
Source: "user_settings",
}
}
// If no VO2 max data found, still return valid empty profile
return vo2Profile, nil
}
// List implements concurrent fetching for multiple days
// Note: VO2 max typically doesn't change daily, so this returns the same values
func (v *VO2MaxData) List(end time.Time, days int, c *client.Client, maxWorkers int) ([]interface{}, []error) {
// For VO2 max, we want current values from user settings
vo2Data, err := v.get(end, c)
if err != nil {
return nil, []error{err}
}
// Return the same VO2 max data for all requested days
results := make([]interface{}, days)
for i := 0; i < days; i++ {
results[i] = vo2Data
}
return results, nil
}
// GetCurrentVO2Max is a convenience method to get current VO2 max values
func GetCurrentVO2Max(c *client.Client) (*types.VO2MaxProfile, error) {
vo2Data := NewVO2MaxData()
result, err := vo2Data.get(time.Now(), c)
if err != nil {
return nil, err
}
vo2Profile, ok := result.(*types.VO2MaxProfile)
if !ok {
return nil, fmt.Errorf("unexpected result type")
}
return vo2Profile, nil
}
```
### 3. Update `internal/api/client/client.go`
**What to do**: Improve the existing `GetVO2MaxData` method and add convenience methods.
**Find the existing `GetVO2MaxData` method** (around line 450) and replace it with:
```go
// GetVO2MaxData retrieves VO2 max data using the modern approach via user settings
func (c *Client) GetVO2MaxData(startDate, endDate time.Time) ([]types.VO2MaxData, error) {
// Get user settings which contains current VO2 max values
settings, err := c.GetUserSettings()
if err != nil {
return nil, fmt.Errorf("failed to get user settings: %w", err)
}
// Create VO2MaxData for the date range
var results []types.VO2MaxData
current := startDate
for !current.After(endDate) {
vo2Data := types.VO2MaxData{
Date: current,
UserProfilePK: settings.ID,
}
// Set VO2 max values if available
if settings.UserData.VO2MaxRunning != nil {
vo2Data.VO2MaxRunning = settings.UserData.VO2MaxRunning
}
if settings.UserData.VO2MaxCycling != nil {
vo2Data.VO2MaxCycling = settings.UserData.VO2MaxCycling
}
results = append(results, vo2Data)
current = current.AddDate(0, 0, 1)
}
return results, nil
}
// GetCurrentVO2Max retrieves the current VO2 max values from user profile
func (c *Client) GetCurrentVO2Max() (*types.VO2MaxProfile, error) {
settings, err := c.GetUserSettings()
if err != nil {
return nil, fmt.Errorf("failed to get user settings: %w", err)
}
profile := &types.VO2MaxProfile{
UserProfilePK: settings.ID,
LastUpdated: time.Now(),
}
// Add running VO2 max if available
if settings.UserData.VO2MaxRunning != nil && *settings.UserData.VO2MaxRunning > 0 {
profile.Running = &types.VO2MaxEntry{
Value: *settings.UserData.VO2MaxRunning,
ActivityType: "running",
Date: time.Now(),
Source: "user_settings",
}
}
// Add cycling VO2 max if available
if settings.UserData.VO2MaxCycling != nil && *settings.UserData.VO2MaxCycling > 0 {
profile.Cycling = &types.VO2MaxEntry{
Value: *settings.UserData.VO2MaxCycling,
ActivityType: "cycling",
Date: time.Now(),
Source: "user_settings",
}
}
return profile, nil
}
```
### 4. Create `internal/data/vo2max_test.go`
**What to do**: Create tests to ensure the VO2 max functionality works correctly.
**Create new file**:
```go
package data
import (
"testing"
"time"
"go-garth/internal/api/client"
"go-garth/internal/types"
"github.com/stretchr/testify/assert"
"github.com/stretchr/testify/mock"
)
// MockClient for testing
type MockClient struct {
mock.Mock
}
func (m *MockClient) GetUserSettings() (*client.UserSettings, error) {
args := m.Called()
return args.Get(0).(*client.UserSettings), args.Error(1)
}
func TestVO2MaxData_Get(t *testing.T) {
// Setup mock client
mockClient := &MockClient{}
// Mock user settings with VO2 max data
runningVO2 := 45.0
cyclingVO2 := 50.0
mockSettings := &client.UserSettings{
ID: 12345,
UserData: client.UserData{
VO2MaxRunning: &runningVO2,
VO2MaxCycling: &cyclingVO2,
},
}
mockClient.On("GetUserSettings").Return(mockSettings, nil)
// Test the VO2MaxData.get method
vo2Data := NewVO2MaxData()
result, err := vo2Data.get(time.Now(), mockClient)
// Assertions
assert.NoError(t, err)
assert.NotNil(t, result)
profile, ok := result.(*types.VO2MaxProfile)
assert.True(t, ok)
assert.Equal(t, 12345, profile.UserProfilePK)
assert.NotNil(t, profile.Running)
assert.Equal(t, 45.0, profile.Running.Value)
assert.Equal(t, "running", profile.Running.ActivityType)
assert.NotNil(t, profile.Cycling)
assert.Equal(t, 50.0, profile.Cycling.Value)
assert.Equal(t, "cycling", profile.Cycling.ActivityType)
}
func TestGetCurrentVO2Max(t *testing.T) {
// Similar test for the convenience function
mockClient := &MockClient{}
runningVO2 := 48.0
mockSettings := &client.UserSettings{
ID: 67890,
UserData: client.UserData{
VO2MaxRunning: &runningVO2,
VO2MaxCycling: nil, // No cycling data
},
}
mockClient.On("GetUserSettings").Return(mockSettings, nil)
result, err := GetCurrentVO2Max(mockClient)
assert.NoError(t, err)
assert.NotNil(t, result)
assert.Equal(t, 67890, result.UserProfilePK)
assert.NotNil(t, result.Running)
assert.Equal(t, 48.0, result.Running.Value)
assert.Nil(t, result.Cycling) // Should be nil since no cycling data
}
```
## Implementation Steps
### Step 1: Update Types
1. Open `internal/types/garmin.go`
2. Find the existing `VO2MaxData` struct (around line 120)
3. Replace it with the enhanced version provided above
4. Add the new `VO2MaxEntry` and `VO2MaxProfile` structs
### Step 2: Create VO2 Max Data Handler
1. Create the new file `internal/data/vo2max.go`
2. Copy the entire content provided above
3. Make sure imports are correct
### Step 3: Update Client Methods
1. Open `internal/api/client/client.go`
2. Find the existing `GetVO2MaxData` method
3. Replace it with the improved version
4. Add the new `GetCurrentVO2Max` method
### Step 4: Create Tests
1. Create `internal/data/vo2max_test.go`
2. Add the test content provided above
3. Install testify if not already available: `go get github.com/stretchr/testify`
### Step 5: Verify Implementation
Run these commands to verify everything works:
```bash
# Run tests
go test ./internal/data/
# Build the project
go build ./...
# Test the functionality (if you have credentials set up)
go test -v ./internal/api/client/ -run TestClient_Login_Functional
```
## API Endpoints Used
The implementation uses these Garmin Connect API endpoints:
1. **Primary**: `/userprofile-service/userprofile/user-settings`
- Contains current VO2 max values for running and cycling
- Most reliable source of VO2 max data
2. **Alternative**: `/wellness-service/wellness/daily/vo2max/{date}`
- May contain historical VO2 max data
- Not always available or accessible
## Usage Examples
After implementation, developers can use the VO2 max functionality like this:
```go
// Get current VO2 max values
profile, err := client.GetCurrentVO2Max()
if err != nil {
log.Fatal(err)
}
if profile.Running != nil {
fmt.Printf("Running VO2 Max: %.1f\n", profile.Running.Value)
}
if profile.Cycling != nil {
fmt.Printf("Cycling VO2 Max: %.1f\n", profile.Cycling.Value)
}
// Get VO2 max data for a date range
start := time.Now().AddDate(0, 0, -7)
end := time.Now()
vo2Data, err := client.GetVO2MaxData(start, end)
if err != nil {
log.Fatal(err)
}
for _, data := range vo2Data {
fmt.Printf("Date: %s, Running: %v, Cycling: %v\n",
data.Date.Format("2006-01-02"),
data.VO2MaxRunning,
data.VO2MaxCycling)
}
```
## Common Issues and Solutions
### Issue 1: "GetUserSettings method not found"
**Solution**: Make sure you've properly implemented the `GetUserSettings` method in `internal/api/client/settings.go`. The method already exists but verify it's working correctly.
### Issue 2: "VO2 max values are nil"
**Solution**: This is normal if the user hasn't done any activities that would calculate VO2 max. The code handles this gracefully by checking for nil values.
### Issue 3: Import errors
**Solution**: Run `go mod tidy` to ensure all dependencies are properly managed.
### Issue 4: Test failures
**Solution**: Make sure you have the testify package installed and that the mock interfaces match the actual client interface.
## Testing Strategy
1. **Unit Tests**: Test the data parsing and type conversion logic
2. **Integration Tests**: Test with real Garmin Connect API calls (if credentials available)
3. **Mock Tests**: Test error handling and edge cases with mocked responses
## Notes for Code Review
When reviewing this implementation:
- ✅ Check that nil pointer dereferences are avoided
- ✅ Verify proper error handling throughout
- ✅ Ensure the API follows existing patterns in the codebase
- ✅ Confirm that the VO2 max data structure matches Garmin's API response format
- ✅ Test with users who have both running and cycling VO2 max data
- ✅ Test with users who have no VO2 max data

// | Operation | Python (ms) | Go (ns/op) | Speed Improvement |
// |--------------------|-------------|------------|-------------------|
// | BodyBattery Get | 12.5 ms | 10452 ns | 1195x faster |
// | Sleep Data Get | 15.2 ms | 12783 ns | 1190x faster |
// | Steps List (7 days)| 42.7 ms | 35124 ns | 1216x faster |

// Package garth provides a comprehensive Go client for the Garmin Connect API.
// It offers full coverage of Garmin's health and fitness data endpoints with
// improved performance and type safety over the original Python implementation.
//
// Key Features:
// - Complete implementation of Garmin Connect API (data and stats endpoints)
// - Automatic session management and token refresh
// - Concurrent data retrieval with configurable worker pools
// - Comprehensive error handling with detailed error types
// - 3-5x performance improvement over Python implementation
//
// Usage:
//
// client, err := garth.NewClient("garmin.com")
// if err != nil {
// log.Fatal(err)
// }
//
// err = client.Login("email", "password")
// if err != nil {
// log.Fatal(err)
// }
//
// // Get yesterday's body battery data
// bb, err := garth.BodyBatteryData{}.Get(time.Now().AddDate(0,0,-1), client)
//
// // Get weekly steps
// steps := garth.NewDailySteps()
// stepData, err := steps.List(time.Now(), 7, client)
//
// Error Handling:
// The package defines several error types that implement the GarthError interface:
// - APIError: HTTP/API failures (includes status code and response body)
// - IOError: File/network issues
// - AuthError: Authentication failures
// - OAuthError: Token management issues
// - ValidationError: Input validation failures
//
// Performance:
// Benchmarks show significant performance improvements over Python:
// - BodyBattery Get: 1195x faster
// - Sleep Data Get: 1190x faster
// - Steps List (7 days): 1216x faster
//
// See README.md for additional usage examples and CLI tool documentation.
