Recipe Finder using ReactJS

In this project article, we will be creating a recipe finder application using the React library. We have given the application the name “GeeksforGeeks Recipe Finder“. This application is completely developed in ReactJS and mainly focuses on the functional components and also manages the various states of the application.

This application allows users to search for a wide range of recipes for different dishes. There are default recipes displayed to the user when the user visits the application for the first time. All the logic of recipe research, getting the results, and displaying them in the card format is implemented using JSX.

Prerequisites and Technologies:

• ReactJS
• CSS
• JSX
• Function Components in React

Approach:

For creating the Recipe Finder application using ReactJS, we have developed a search bar in which the user can input the dish name for which he or she needs the recipe. Once the user enters the dish name, the recipes are fetched from an Edamam API. This contains a large set of food databases, along with the dishes and their recipes. So according to the user’s search, the matching dishes and their recipes are shown to the user in the form of card elements. We are using Tailwind CSS for styling the UI components of the application.

Project Structure:

Steps to create the application:

Step 1: Set up the React project using the below command in VSCode IDE.

npx create-react-app recipe-app

Step 2: Navigate to the newly created project folder by executing the below command.

cd recipe-app

Step 3: As we are using Tailwind CSS for styling, we need to install it using the npm manager. So execute the below command in the terminal, to install the tailwind CSS.

npm install -D tailwindcss
npx tailwindcss init

The updated dependencies in package.json will look like this:

  "dependencies": {
    "@testing-library/jest-dom": "^5.17.0",
    "@testing-library/react": "^13.4.0",
    "@testing-library/user-event": "^13.5.0",
    "react": "^18.2.0",
    "react-dom": "^18.2.0",
    "react-scripts": "5.0.1",
    "web-vitals": "^2.1.4"
  },
"devDependencies": {
        "tailwindcss": "^3.3.3"
      }

Step 4: After executing the above command, a ‘tailwind.config.js‘ will be generated, so paste the below content in this file for the correct configuration.

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./src/**/*.{js,jsx,ts,tsx}",
  ],
  theme: {
    extend: {},
  },
  plugins: [],
}

Step 5: Now, in the src directory create a file as RecipeCard.jsx, which will consist of the code for presenting the recipes to the user.

Example: Insert the below code in the App.js and RecipeCard.jsx file mentioned in the above directory structure.

Javascript

// App.js

import React, { useEffect, useState } from 'react';
import RecipeCard from './RecipeCard';

const App = () => {
    const APP_ID = 'YOUR_API_ID';
    const APP_KEY = 'YOUR_API_KEY';
    const [food_recipes, setfood_recipes] = useState([]);
    const [search_recipe, setSearch_recipe] = useState('');
    const [search_query, setSearch_Query] = useState('chicken');

    useEffect(() => {
        getRecipesFunction();
    }, [search_query]);

    const getRecipesFunction = async () => {
        const response = await fetch(
`https://api.edamam.com/search?q=${search_query}&app_id=${APP_ID}&app_key=${APP_KEY}`
        );
        const data = await response.json();
        setfood_recipes(data.hits);
    };

    const updateSearchFunction = (e) => {
        setSearch_recipe(e.target.value);
    };

    const getSearchFunction = (e) => {
        e.preventDefault();
        setSearch_Query(search_recipe);
        setSearch_recipe('');
    };

Steps to run the application:

Step 1: Run the application by executing the following command in the terminal.

npm start
or
npm run start

Step 2: Open a web browser like Chrome or Firefox and type the following URL in the address bar.

http://localhost:3000/

Step 3: Change API Key and API Code in your App.js

 const APP_ID = 'YOUR_API_ID';
 const APP_KEY = 'YOUR_API_KEY';

Output:
