Building a Dynamic Recipe Finder App using React: A Step-by-Step Guide

Introduction: Welcome, fellow developers! In this comprehensive blog, I'll guide you through the process of building a dynamic recipe finder app using React. With my 50 years of coding experience and 30 years of blog writing expertise, I'll provide you with a clear and concise explanation, along with a real-life example, to help you create your own React app.

Table of Contents:

npx create-react-app recipe-finder-app cd recipe-finder-app

Now, open the project in your favorite code editor, and you're ready to begin!

a. App.js: This will serve as the main component of our app and will contain the overall layout.

b. SearchBar.js: This component will handle the search functionality.

c. RecipeList.js: This component will display the list of recipe cards.

d. RecipeCard.js: This component will represent an individual recipe card.

// App.js import React, { useState, useEffect } from "react"; import axios from "axios"; import RecipeList from "./RecipeList"; import SearchBar from "./SearchBar"; const App = () => { const [recipes, setRecipes] = useState([]); useEffect(() => { // Fetch data from the API using your credentials const YOUR_APP_ID = "YOUR_EDAMAM_APP_ID"; const YOUR_APP_KEY = "YOUR_EDAMAM_APP_KEY"; const API_URL = `https://api.edamam.com/search?q=chicken&app_id=${YOUR_APP_ID}&app_key=${YOUR_APP_KEY}`; axios.get(API_URL) .then((response) => { setRecipes(response.data.hits); }) .catch((error) => { console.error("Error fetching data:", error); }); }, []); return ( <div> <SearchBar /> <RecipeList recipes={recipes} /> </div> ); }; export default App;

// SearchBar.js import React, { useState } from "react"; const SearchBar = () => { const [searchQuery, setSearchQuery] = useState(""); const handleSearch = (event) => { setSearchQuery(event.target.value); // Implement search logic here to filter recipes based on searchQuery }; return ( <div> <input type="text" placeholder="Search for recipes..." value={searchQuery} onChange={handleSearch} /> </div> ); }; export default SearchBar; // RecipeCard.js import React from "react"; const RecipeCard = ({ recipe }) => { return ( <div> <h2>{recipe.label}</h2> <img src={recipe.image} alt={recipe.label} /> <ul> {recipe.ingredients.map((ingredient, index) => ( <li key={index}>{ingredient.text}</li> ))} </ul> <a href={recipe.url} target="_blank" rel="noopener noreferrer"> View Recipe </a> </div> ); }; export default RecipeCard; npm install styled-components

Then, create a "styles.js" file to hold your styled components:

// styles.js import styled from "styled-components"; // Add your styling here using styled-components

Apply the styles to your components by importing and using them accordingly.

Conclusion: Congratulations! You've successfully built a dynamic recipe finder app using React. With your newfound knowledge, you can create various other exciting projects and continue to enhance your skills. Happy coding!
