Understanding What We're Building
Imagine creating CookPal - the ultimate culinary companion that turns anyone into a confident cook. Your mission is to build an app that helps users discover amazing recipes, learn about ingredients, and get personalized meal suggestions based on what they have in their kitchen.
TheMealDB is your digital cookbook - containing thousands of recipes from around the world, complete with ingredients, instructions, and beautiful food photography.
Setting Up Your React Environment
Let's prepare your digital kitchen:
npx create-react-app cookpal
cd cookpal
npm start
Think of this as organizing your kitchen before cooking a feast. React is your cooking station, and TheMealDB is your comprehensive recipe collection that never runs out of inspiration.
Understanding Recipe APIs
A recipe API is like having a master chef who knows every dish from every cuisine in the world. You can ask specific questions like "What can I make with chicken?" or "Show me Italian desserts," and they'll instantly provide detailed recipes with instructions.
TheMealDB offers several "cooking conversations":
-
Search by name:
https://www.themealdb.com/api/json/v1/1/search.php?s=
-
Random meal:
https://www.themealdb.com/api/json/v1/1/random.php
-
Lookup by ID:
https://www.themealdb.com/api/json/v1/1/lookup.php?i=
-
Filter by ingredient:
https://www.themealdb.com/api/json/v1/1/filter.php?i=
-
Browse categories:
https://www.themealdb.com/api/json/v1/1/categories.php
Searching for Recipes
Let's start by creating a recipe search that feels as natural as asking a friend for cooking advice:
import React, { useState } from 'react';
function RecipeSearch() {
const [recipes, setRecipes] = useState([]);
const [searchTerm, setSearchTerm] = useState('');
const [loading, setLoading] = useState(false);
const [error, setError] = useState(null);
const searchRecipes = async () => {
if (!searchTerm.trim()) {
setError('Please enter a recipe name to search');
return;
}
setLoading(true);
setError(null);
try {
// Ask TheMealDB: "Do you have any recipes with this name?"
const response = await fetch(
`https://www.themealdb.com/api/json/v1/1/search.php?s=${encodeURIComponent(searchTerm)}`
);
if (!response.ok) {
throw new Error(`Search failed: ${response.status}`);
}
const data = await response.json();
// TheMealDB returns null if no recipes found
if (data.meals) {
setRecipes(data.meals);
} else {
setRecipes([]);
setError('No recipes found. Try a different search term!');
}
} catch (error) {
console.error('Recipe search failed:', error);
setError('Failed to search recipes. Please try again.');
} finally {
setLoading(false);
}
};
const handleKeyPress = (e) => {
if (e.key === 'Enter') {
searchRecipes();
}
};
return (
<div style={{ padding: '20px', maxWidth: '800px', margin: '0 auto' }}>
<h2>🔍 Recipe Search</h2>
<div style={{ marginBottom: '20px', display: 'flex', gap: '10px' }}>
<input
type="text"
value={searchTerm}
onChange={(e) => setSearchTerm(e.target.value)}
onKeyPress={handleKeyPress}
placeholder="Search for recipes (e.g., pasta, chicken, cake)..."
style={{

}}
/>
<button
onClick={searchRecipes}
disabled={loading}
style={{
backgroundColor: '#ff6b35',
color: 'white',
padding: '12px 24px',
border: 'none',
borderRadius: '8px',
cursor: loading ? 'not-allowed' : 'pointer',
fontSize: '16px'
}}
>
{loading ? '🔍 Searching...' : '👨🍳 Find Recipes'}
</button>
</div>
{error && (
<div style={{
backgroundColor: '#ffebee',
color: '#c62828',
padding: '15px',
borderRadius: '8px',
marginBottom: '20px'
}}>
{error}
</div>
)}
{recipes.length > 0 && (
<div>
<h3>🍽️ Found {recipes.length} delicious recipes:</h3>
<div style={{
display: 'grid',
gridTemplateColumns: 'repeat(auto-fill, minmax(300px, 1fr))',
gap: '20px',
marginTop: '20px'
}}>
{recipes.map((recipe) => (
<RecipeCard key={recipe.idMeal} recipe={recipe} />
))}
</div>
</div>
)}
</div>
);
}
// Component to display individual recipe cards
function RecipeCard({ recipe }) {
return (
<div style={{
backgroundColor: 'white',
borderRadius: '12px',
overflow: 'hidden',
boxShadow: '0 4px 6px rgba(0,0,0,0.1)',
transition: 'transform 0.2s'
}}>
<img

<div style={{ padding: '15px' }}>
<h3 style={{ margin: '0 0 10px 0', color: '#333' }}>

<p style={{ color: '#666', fontSize: '14px', margin: '5px 0' }}>

<button style={{

borderRadius: '6px',

}}>

</button>
</div>
</div>
);
}
Breaking this down:
-
useState
keeps track of our recipe collection and search status -
fetch()
is our messenger that goes to TheMealDB's kitchen -
encodeURIComponent()
ensures search terms are properly formatted - The grid layout displays recipes like a beautiful cookbook spread
Fetching Detailed Recipe Information
When users want the full recipe, we need to get all the cooking details:
function RecipeDetails({ recipeId }) {
const [recipe, setRecipe] = useState(null);
const [loading, setLoading] = useState(false);
const [ingredients, setIngredients] = useState([]);
const fetchRecipeDetails = async () => {
setLoading(true);
try {
const response = await fetch(
`https://www.themealdb.com/api/json/v1/1/lookup.php?i=${recipeId}`
);
const data = await response.json();
if (data.meals && data.meals[0]) {
const recipeData = data.meals[0];
setRecipe(recipeData);
// Extract ingredients and measurements (TheMealDB stores them separately)
const ingredientsList = extractIngredients(recipeData);
setIngredients(ingredientsList);
}
} catch (error) {
console.error('Failed to fetch recipe details:', error);
} finally {
setLoading(false);
}
};
// TheMealDB stores ingredients as strIngredient1, strIngredient2, etc.
const extractIngredients = (recipeData) => {
const ingredients = [];
for (let i = 1; i <= 20; i++) {
const ingredient = recipeData[`strIngredient${i}`];
const measure = recipeData[`strMeasure${i}`];
if (ingredient && ingredient.trim()) {
ingredients.push({
name: ingredient.trim(),
measure: measure ? measure.trim() : ''
});
}
}
return ingredients;
};
useEffect(() => {
if (recipeId) {
fetchRecipeDetails();
}
}, [recipeId]);
if (loading) {
return <div style={{ textAlign: 'center', padding: '40px' }}>
🍳 Loading recipe details...

}
if (!recipe) {
return <div>Recipe not found</div>;
}
return (
<div style={{ maxWidth: '800px', margin: '0 auto', padding: '20px' }}>
<div style={{ textAlign: 'center', marginBottom: '30px' }}>

);
}
Browsing by Categories and Ingredients
Let users explore recipes like browsing through different sections of a market:
function RecipeBrowser() {
const [categories, setCategories] = useState([]);
const [selectedCategory, setSelectedCategory] = useState(null);
const [categoryRecipes, setCategoryRecipes] = useState([]);
const [availableIngredients] = useState([
'chicken', 'beef', 'pork', 'fish', 'rice', 'pasta',
'tomato', 'onion', 'garlic', 'cheese', 'eggs'
]);
const fetchCategories = async () => {
try {
const response = await fetch('https://www.themealdb.com/api/json/v1/1/categories.php');
const data = await response.json();
setCategories(data.categories || []);
} catch (error) {
console.error('Failed to fetch categories:', error);
}
};
const fetchRecipesByCategory = async (categoryName) => {
try {
const response = await fetch(
`https://www.themealdb.com/api/json/v1/1/filter.php?c=${categoryName}`
);
const data = await response.json();
setCategoryRecipes(data.meals || []);
setSelectedCategory(categoryName);
} catch (error) {
console.error('Failed to fetch recipes by category:', error);
}
};
const fetchRecipesByIngredient = async (ingredient) => {
try {
const response = await fetch(
`https://www.themealdb.com/api/json/v1/1/filter.php?i=${ingredient}`
);
const data = await response.json();
setCategoryRecipes(data.meals || []);
setSelectedCategory(`Recipes with ${ingredient}`);
} catch (error) {
console.error('Failed to fetch recipes by ingredient:', error);
}
};
const getRandomRecipe = async () => {
try {
const response = await fetch('https://www.themealdb.com/api/json/v1/1/random.php');
const data = await response.json();
if (data.meals && data.meals[0]) {
setCategoryRecipes([data.meals[0]]);
setSelectedCategory('Random Recipe Surprise');
}
} catch (error) {
console.error('Failed to fetch random recipe:', error);
}
};
useEffect(() => {
fetchCategories();
}, []);
return (
<div style={{ padding: '20px', maxWidth: '1200px', margin: '0 auto' }}>
<h2>🗂️ Browse Recipes</h2>
<div style={{ marginBottom: '30px' }}>

))}
</div>
</div>
)}
</div>
);
}
Error Handling and User Experience
Cooking apps should be forgiving - like a patient cooking instructor:
const [networkError, setNetworkError] = useState(false);
const [retryAttempts, setRetryAttempts] = useState(0);
const fetchWithRetry = async (url, maxRetries = 3) => {
for (let attempt = 0; attempt <= maxRetries; attempt++) {
try {
const response = await fetch(url);
if (!response.ok) {
throw new Error(`HTTP ${response.status}`);
}
setNetworkError(false);
setRetryAttempts(0);
return await response.json();
} catch (error) {
if (attempt === maxRetries) {
setNetworkError(true);
setRetryAttempts(attempt + 1);
throw error;
}
// Wait before retrying (exponential backoff)
await new Promise(resolve => setTimeout(resolve, Math.pow(2, attempt) * 1000));
}
}
};
// Graceful handling of missing recipe data
const formatRecipeData = (recipe) => {
return {
id: recipe.idMeal,
name: recipe.strMeal || 'Unnamed Recipe',
image: recipe.strMealThumb || '/placeholder-food.jpg',
category: recipe.strCategory || 'Unknown',
area: recipe.strArea || 'International',
instructions: recipe.strInstructions || 'Instructions not available',
youtube: recipe.strYoutube || null,
ingredients: extractIngredients(recipe)
};
};
// Show helpful error messages
const ErrorMessage = ({ error, onRetry }) => (
<div style={{
backgroundColor: '#ffebee',
border: '1px solid #f44336',
borderRadius: '8px',
padding: '20px',
textAlign: 'center',
margin: '20px 0'
}}>
<h3>🤔 Oops! Something went wrong</h3>
<p>{error}</p>
<button
onClick={onRetry}
style={{
backgroundColor: '#f44336',
color: 'white',
border: 'none',
padding: '10px 20px',
borderRadius: '6px',
cursor: 'pointer'
}}
>
🔄 Try Again
</button>
</div>
);
Local Development Tips for Global Access
Working from Bamenda or areas with slower connections? Here are some optimization tips:
// Cache frequently accessed data
const recipeCache = new Map();
const CACHE_DURATION = 10 * 60 * 1000; // 10 minutes
const getCachedRecipe = (id) => {
const cached = recipeCache.get(id);
if (cached && (Date.now() - cached.timestamp) < CACHE_DURATION) {
return cached.data;
}
return null;
};
const setCachedRecipe = (id, data) => {
recipeCache.set(id, {
data,
timestamp: Date.now()
});
};
// Optimize image loading
const LazyImage = ({ src, alt, ...props }) => {
const [loaded, setLoaded] = useState(false);
const [error, setError] = useState(false);
return (
<div style={{ position: 'relative', backgroundColor: '#f5f5f5' }}>
{!loaded && !error && (
<div style={{
position: 'absolute',
top: '50%',
left: '50%',
transform: 'translate(-50%, -50%)'
}}>
🍽️ Loading...
</div>
)}
<img
src={src}
alt={alt}
onLoad={() => setLoaded(true)}
onError={() => setError(true)}
style={{
...props.style,
opacity: loaded ? 1 : 0,
transition: 'opacity 0.3s'
}}
/>
{error && (
<div style={{
position: 'absolute',
top: '50%',
left: '50%',
transform: 'translate(-50%, -50%)',
textAlign: 'center'
}}>
🖼️ Image unavailable
</div>
)}
</div>
);
};
