📦 Installation

# npm
npm install @api-wrappers/pokeapi

# yarn
yarn add @api-wrappers/pokeapi

# pnpm
pnpm add @api-wrappers/pokeapi

🚀 Quick Start

import { PokeApiClient } from '@api-wrappers/pokeapi';

// Create a client
const client = new PokeApiClient();

// Get a Pokemon by name
const pikachu = await client.getPokemon('pikachu');
console.log(pikachu.data.name); // 'pikachu'
console.log(pikachu.data.types); // [{ slot: 1, type: { name: 'electric', url: '...' } }]

// Get a Pokemon by ID
const charizard = await client.getPokemon(6);
console.log(charizard.data.name); // 'charizard'

📖 Usage Examples

Basic Pokemon Operations

import { PokeApiClient } from '@api-wrappers/pokeapi';

const client = new PokeApiClient();

// Get Pokemon list with pagination
const pokemonList = await client.getPokemonList({ limit: 20, offset: 0 });
console.log(`Found ${pokemonList.data.count} Pokemon total`);
console.log(pokemonList.data.results[0].name); // 'bulbasaur'

// Get detailed Pokemon information
const bulbasaur = await client.getPokemon('bulbasaur');
console.log(bulbasaur.data);
console.log(bulbasaur.data.stats); // Base stats
console.log(bulbasaur.data.abilities); // Abilities
console.log(bulbasaur.data.types); // Types

Pokemon Species and Evolution

// Get species information
const species = await client.getPokemonSpecies('pikachu');
console.log(species.data.evolution_chain.url); // Evolution chain URL
console.log(species.data.growth_rate.name); // Growth rate
console.log(species.data.egg_groups); // Egg groups

Abilities, Types, and Moves

// Get ability information
const staticAbility = await client.getAbility('static');
console.log(staticAbility.data.effect_entries[0].short_effect);

// Get type information
const electricType = await client.getType('electric');
console.log(electricType.data.damage_relations.no_damage_to); // Weaknesses

// Get move information
const thunderbolt = await client.getMove('thunderbolt');
console.log(thunderbolt.data.power); // 90
console.log(thunderbolt.data.accuracy); // 100

Items and Berries

// Get item information
const potion = await client.getItem('potion');
console.log(potion.data.cost); // 300
console.log(potion.data.effect_entries[0].short_effect);

// Get berry information
const cherri = await client.getBerry('cherri');
console.log(cherri.data.growth_time); // 3
console.log(cherri.data.max_harvest); // 5

⚙️ Configuration

Basic Configuration

const client = new PokeApiClient({
  timeout: 10000, // Request timeout in milliseconds
  retries: 3, // Number of retries for failed requests
});

Advanced Configuration

const client = new PokeApiClient({
  baseURL: 'https://pokeapi.co/api/v2', // Custom base URL
  timeout: 15000,
  retries: 5,
  headers: {
    'User-Agent': 'My-App/1.0.0',
    Authorization: 'Bearer your-token', // If needed
  },
  // Rate limiting (if implemented)
  rateLimit: {
    requests: 100,
    period: 60000, // per minute
  },
  // Caching (if implemented)
  cache: {
    ttl: 300000, // 5 minutes
    maxSize: 100,
  },
});

API Configuration

// Get current API configuration
const config = client.getApiConfig();
console.log(config.version); // 'v2'
console.log(config.language); // 'en'
console.log(config.baseURL); // 'https://pokeapi.co/api/v2'

🛡️ Error Handling

The client provides comprehensive error handling with specific error types:

import { PokeApiClient, ApiError, NotFoundError } from '@api-wrappers/pokeapi';

const client = new PokeApiClient();

try {
  const pokemon = await client.getPokemon('nonexistent');
} catch (error) {
  if (error instanceof NotFoundError) {
    console.log('Pokemon not found:', error.message);
  } else if (error instanceof ApiError) {
    console.log('API Error:', error.status, error.code);
  } else {
    console.log('Unexpected error:', error);
  }
}

Available Error Types

ApiError - Base API error
NetworkError - Network-related errors
TimeoutError - Request timeout
NotFoundError - 404 Not Found
RateLimitError - Rate limit exceeded
ValidationError - Input validation errors

🔍 Data Validation

The client includes built-in validation methods:

const response = await client.getPokemon('pikachu');

// Validate response data
if (client.isValidPokemon(response.data)) {
  console.log('Valid Pokemon data');
}

// Validate list responses
const listResponse = await client.getPokemonList();
if (client.isValidPokemonList(listResponse.data)) {
  console.log('Valid Pokemon list');
}

📊 Response Metadata

All responses include useful metadata:

const response = await client.getPokemon('pikachu');

console.log(response.status); // HTTP status code
console.log(response.success); // true/false
console.log(response.metadata.duration); // Request duration in ms
// Rate limit info (when available)
// response.metadata.rateLimit

🧪 Testing

The package includes comprehensive test utilities for your applications:

import {
  createMockApiResponse,
  createMockPokemon,
} from '@api-wrappers/pokeapi';

// Create mock responses for testing
const mockResponse = createMockApiResponse(
  createMockPokemon({ id: 25, name: 'pikachu' })
);

// Use in your tests
expect(mockResponse.success).toBe(true);
expect(mockResponse.data.name).toBe('pikachu');

Automatic Retries - Failed requests are automatically retried
Rate Limit Detection - Respects API rate limits
Request Caching - Intelligent response caching (configurable)
Timeout Handling - Configurable request timeouts
Connection Pooling - Efficient HTTP connection reuse

🐛 Troubleshooting

Common Issues

Request Timeout

// Increase timeout for slow connections
const client = new PokeApiClient({ timeout: 30000 });

Rate Limiting

// The client automatically handles rate limits
// Check response metadata for rate limit info
const response = await client.getPokemon('pikachu');
if (response.metadata.rateLimit?.remaining === 0) {
  console.log('Rate limit reached');
}

Network Errors

try {
  const pokemon = await client.getPokemon('pikachu');
} catch (error) {
  if (error instanceof NetworkError) {
    console.log('Network issue, will retry automatically');
  }
}
