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. ================================================ FILE: implementation-plan-steps-1-2.md ================================================ # 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

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

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(`(.+?)`) ticketRegex = regexp.MustCompile(`embed\?ticket=([^"]+)"`) ) // Login performs SSO login with email and password func (c *Client) Login(email, password string) error { //

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

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** -

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. ================================================ FILE: v02.md ================================================ # 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 ================================================ FILE: internal/api/client/auth.go ================================================ package client import ( "time" ) // OAuth1Token represents OAuth 1.0a credentials type OAuth1Token struct { Token string TokenSecret string CreatedAt time.Time } // Expired checks if token is expired (OAuth1 tokens typically don't expire but we'll implement for consistency) func (t *OAuth1Token) Expired() bool { return false // OAuth1 tokens don't typically expire } // OAuth2Token represents OAuth 2.0 credentials type OAuth2Token struct { AccessToken string RefreshToken string TokenType string ExpiresIn int ExpiresAt time.Time } // Expired checks if token is expired func (t *OAuth2Token) Expired() bool { return time.Now().After(t.ExpiresAt) } // RefreshIfNeeded refreshes token if expired (implementation pending) func (t *OAuth2Token) RefreshIfNeeded(client *Client) error { // Placeholder for token refresh logic return nil } ================================================ FILE: internal/api/client/auth_test.go ================================================ package client_test import ( "testing" "github.com/sstent/go-garth/internal/api/client" "github.com/sstent/go-garth/internal/auth/credentials" "github.com/stretchr/testify/assert" "github.com/stretchr/testify/require" ) func TestClient_Login_Functional(t *testing.T) { if testing.Short() { t.Skip("Skipping functional test in short mode") } // Load credentials from .env file email, password, domain, err := credentials.LoadEnvCredentials() require.NoError(t, err, "Failed to load credentials from .env file.
