Requirements

• Node.js: >=20.0.0
• npm: >=9.0.0 (included with Node.js 20+)

Installation

npm install trainingpeaks-sdk

⚠️ Node.js Version: This SDK requires Node.js 20.0.0 or higher due to the use of modern APIs like crypto.randomUUID(). Node.js 18 and earlier are not supported.

Quick Start

Authentication & Basic Usage

import { createTrainingPeaksSdk } from 'trainingpeaks-sdk';

// Initialize the SDK
const sdk = createTrainingPeaksSdk({
  debug: false, // Optional: enable debug logging
  timeout: 30000, // Optional: request timeout in ms
});

// Login with credentials
const loginResult = await sdk.login({
  username: 'your-username',
  password: 'your-password',
});

console.log('Login successful:', loginResult);
// Returns: { token: {...}, user: {...} }

Workout Management

// Get user's workouts list
const workouts = await sdk.getWorkoutsList({
  startDate: '2024-01-01',
  endDate: '2024-12-31',
  // athleteId is optional - uses current user if not provided
});

console.log('Workouts:', workouts);
// Returns: WorkoutListItem[] with id, name, date, etc.

⚠️ Current Limitations: This SDK currently supports authentication and workout list retrieval. Additional features like workout creation, updates, and individual workout details are planned for future releases.

Logout

// Clear authentication and logout
await sdk.logout();
console.log('Logged out successfully');

Error Handling

try {
  const result = await sdk.login({
    username: 'invalid-user',
    password: 'wrong-password',
  });
} catch (error) {
  console.error('Login failed:', error.message);
  // Handle authentication errors
}

Configuration

SDK Configuration

import {
  createTrainingPeaksSdk,
  type TrainingPeaksClientConfig,
} from 'trainingpeaks-sdk';

const config: TrainingPeaksClientConfig = {
  baseUrl: 'https://tpapi.trainingpeaks.com', // Optional
  timeout: 30000, // Optional: request timeout in ms
  debug: true, // Optional: enable debug logging
  headers: {
    // Optional: custom headers
    'User-Agent': 'MyApp/1.0.0',
  },
};

const sdk = createTrainingPeaksSdk(config);

Environment Variables

You can also configure the SDK using environment variables:

# API Base URL (optional)
TRAININGPEAKS_API_BASE_URL=https://tpapi.trainingpeaks.com

# Request timeout in milliseconds (optional)
TRAININGPEAKS_TIMEOUT=30000

# Enable debug logging (optional)
TRAININGPEAKS_DEBUG=true

Error Handling

The SDK provides structured error handling with HTTP-specific error information:

import { createTrainingPeaksSdk } from 'trainingpeaks-sdk';

const sdk = createTrainingPeaksSdk();

try {
  await sdk.login({ username: 'user', password: 'pass' });
} catch (error) {
  // HTTP errors include status, statusText, and response data
  if (error.status) {
    console.error(`HTTP ${error.status}: ${error.statusText}`);
    console.error('Response:', error.data);
  } else {
    console.error('Network or other error:', error.message);
  }
}

TypeScript Support

The SDK is written in TypeScript and provides comprehensive type definitions:

import { createTrainingPeaksSdk } from 'trainingpeaks-sdk';
import type {
  TrainingPeaksClientConfig,
  LoginCredentials,
  GetWorkoutsListCommand,
  WorkoutListItem,
} from 'trainingpeaks-sdk';

// All types are fully typed
const config: TrainingPeaksClientConfig = {
  debug: true,
  timeout: 30000,
};

const credentials: LoginCredentials = {
  username: 'myuser',
  password: 'mypass',
};

const workoutsQuery: GetWorkoutsListCommand = {
  startDate: '2024-01-01',
  endDate: '2024-12-31',
};

Module Exports

The SDK supports multiple import patterns for different use cases:

// Main SDK factory function
import { createTrainingPeaksSdk } from 'trainingpeaks-sdk';

// Type imports
import type {
  TrainingPeaksClientConfig,
  LoginCredentials,
  GetWorkoutsListCommand,
  WorkoutListItem,
} from 'trainingpeaks-sdk';

// ⚠️ UNSTABLE: Internal modules - No SemVer guarantees
// These imports may introduce breaking changes in any version
// Use at your own risk - prefer [public API documentation](./docs/clean-architecture.md#public-api) when possible
import { User } from 'trainingpeaks-sdk/domain';
import { Logger } from 'trainingpeaks-sdk/adapters';
import type { WorkoutType } from 'trainingpeaks-sdk/types';

Architecture

This SDK follows Clean Architecture principles with a hexagonal architecture approach:

• Domain Layer: Core business entities and rules
• Application Layer: Business logic orchestration and contracts
• Adapters Layer: External integrations and concrete implementations (formerly Infrastructure) - see migration guide for infrastructure → adapters transition details

Key Benefits:

• 🧪 Highly Testable: Each layer can be tested independently
• 🔄 Maintainable: Clear separation of concerns and dependencies
• 🔧 Extensible: Easy to add new features or swap implementations
• 📦 Modular: Use individual components or the complete SDK

Documentation:

• Clean Architecture Guide - Detailed implementation patterns
• PRODUCT.md - Product vision and business context
