Recipe Generator using Next.js

In this tutorial, we’ll create a Recipe Generator App using Next.js, a React framework that allows users to generate random recipes. This type of application can be useful for people looking for new meal ideas or wanting to explore different cuisines. application fetches recipe data from API and displays it to the user.

Output Preview: Let us have a look at how the final output will look like.

Prerequisites:

• NPM & NodeJS
• NextJS
• React Hooks
• REST API

Approach to Create Recipe Generator:

• Setup the Project by Creating a new NextJS project Install the necessary libraries.
• Design the components for app, including a Navbar, RecipeGenerator, RecipeCard.
• We will integrate Edamam Api into our app to fetch recipe data.
• React hooks will be utilized to manage the app’s state, such as search queries, recipes.
• We will Implement a search feature that allows users to search for recipes based on keywords.
• Display the fetched recipes in a grid manner, including images, titles, ingredients etc.
• Bootstrap will be utilized for styling the application.

Steps to Create the Recipe Generator Application:

Step 1: Create a application of NextJS using the following command.

npx create-next-app recipe-generator

Step 2: Navigate to project directory

cd recipe-generator

Step 3: Install the necessary package in your project using the following command.

npm install bootstrap
npm install axios

Step 4: Create the folder structure as shown below and create the files in respective folders.

Project Structure:

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

"dependencies": {
    "axios": "^1.6.7",
    "bootstrap": "^5.3.3",
    "next": "14.1.0",
    "react": "^18",
    "react-dom": "^18"
}

Example: Below are the components which describes the implementation of the Recipe Generator.

Javascript

// page.js

import RecipeGenerator from '@/components/RecipeGenerator';
import React from 'react';

const page = () => {
  return (
    <div>
      <RecipeGenerator />
    </div>
  )
}

export default page

Javascript

// Navbar.js

import React from 'react';
import 'bootstrap/dist/css/bootstrap.min.css';

const Navbar = () => {
  return (
    <nav className="nav justify-content-center navbar-light bg-success">
    <li className="nav-item">
    <a className="nav-link text-light" href="#"><h2>GFG Recipe generator</h2></a>
  </li>

</nav>
  );
};

export default Navbar;

Javascript

// RecipeGenerator.js

'use client'
import { useState, useEffect } from 'react';
import axios from 'axios';
import 'bootstrap/dist/css/bootstrap.min.css';
import Navbar from './Navbar';
import RecipeCard from '@/components/RecipeCard';

  const [recipes, setRecipes] = useState([]);
  const [search, setSearch] = useState('');
  const [selectedRecipe, setSelectedRecipe] = useState(null);

  const APP_KEY = 'YOUR_EDAMAM_APP_KEY';

  const generateRecipe = async () => {
    try {
      const response = await axios.get(`https://api.edamam.com/search?q=${search}&app_id=bbb0cce2&app_key=2fe683efd1286808ab9fc1d52132e3dd`);
      if (response.data.hits.length > 0) {
        setRecipes(response.data.hits);
      }
    } catch (error) {
      console.error('Failed to fetch recipe', error);
    }
  };

  const openModal = (recipe) => {
    setSelectedRecipe(recipe);
    document.getElementById('exampleModal').style.display = 'block';
  };

  const closeModal = () => {
    setSelectedRecipe(null);
    document.getElementById('exampleModal').style.display = 'none';
  };

  return (
    <>
    <Navbar />
    <div className="container mt-3 justify-content-center">
      <div className="row">
        <div className="col mb-4">

          <p>No recipes found</p>
        ) : (

         openModal={openModal}
         closeModal={closeModal}
         selectedRecipe={selectedRecipe}

         />
        )}
    </div>
    </>
  );
};

export default RecipeGenerator;

Javascript

// RecipeCard.js

import React from 'react'
import 'bootstrap/dist/css/bootstrap.min.css';
const RecipeCard = ({recipes, openModal, closeModal, selectedRecipe}) => {
  return (
    <div className="row">
        {

            <div className="modal-body">
                <ul>
                    {selectedRecipe && selectedRecipe.recipe.ingredientLines.map((ingredient, index) => (
                        <li key={index}>{ingredient}</li>
                    ))}
                </ul>
            </div>
        </div>
    </div>
</div>

    </div>

  )
}

export default RecipeCard

Start your application using the following command.

npm run dev

Output: Open web-browser and type the following URL http://localhost:3000/
