🔍 Key Components

1. PokemonCard Component

Purpose: Display Pokémon thumbnail information

Tech Highlights:

• Prop Types Validation
• Responsive image loading
• Dynamic type coloring

interface PokemonCardProps {
  id: number;
  name: string;
  types: PokemonType[];
  sprite: string;
}

const PokemonCard: FC<PokemonCardProps> = ({ id, name, types, sprite }) => {
  // Component implementation
}

2. API Service Layer

Design Rationale: Centralized API calls with error handling wrapper

export const fetchPokemonDetails = async (id: string): Promise<Pokemon> => {
  try {
    const response = await fetch(`https://pokeapi.co/api/v2/pokemon/${id}`);
    if (!response.ok) throw new Error('API Error');
    return await response.json();
  } catch (error) {
    console.error('Fetch error:', error);
    throw error;
  }
};

3. Type System Design

Why Interfaces? Strong typing for API responses and component contracts

interface Pokemon {
  id: number;
  name: string;
  types: Array<{
    slot: number;
    type: {
      name: PokemonType;
      url: string;
    };
  }>;
  // ...15+ additional fields
}

🚀 Performance Optimizations

Batch Fetching

// Home.tsx - Fetch first 151 Pokémon
const loadPokemon = async () => {
  const list = await fetchPokemonList(151);
  const details = await Promise.all(
    list.map(p => fetchPokemonDetails(p.name))
  );
  setPokemonList(details);
};

CSS Optimization Strategy

• Minimal global styles
• Component-scoped CSS
• Hardware-accelerated animations
• Responsive grid layout

📈 API Design Decisions

Why PokeAPI?

• Comprehensive Pokémon data
• Free & open API
• Well-maintained documentation
• Community support

Rate Limiting Strategy

• Client-side caching (localStorage)
• Request throttling
• Error retry mechanism (WIP)
